Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include accounts, after elimination of intercompany accounts and transactions, of Conifer Holdings, Inc. (the “Company” or “Conifer”), its wholly owned subsidiaries, Conifer Insurance Company ("CIC"), White Pine Insurance Company ("WPIC"), Red Cedar Insurance Company ("RCIC"), and Sycamore Insurance Agency, Inc. ("SIA"). CIC, WPIC, and RCIC are collectively referred to as the "Insurance Company Subsidiaries." On a stand-alone basis, Conifer Holdings, Inc. is referred to as the "Parent Company." The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company has applied the rules and regulations of the United States Securities and Exchange Commission (“SEC”) regarding interim financial reporting and therefore the consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments, consisting of items of a normal recurring nature, necessary for a fair presentation of the consolidated interim financial statements, have been included. The results of operations for the nine months ended September 30, 2018 , are not necessarily indicative of the results expected for the year ended December 31, 2018 . These consolidated financial statements and the notes thereto should be read in conjunction with the Company's audited consolidated financial statements and related notes included in its Annual Report on Form 10-K/A for the year ended December 31, 2017 , as filed with the SEC. Business The Company is engaged in the sale of property and casualty insurance products and has organized its business model around two classes of insurance businesses: commercial and personal lines. The Company underwrites a variety of specialty insurance products, including property, general liability, liquor liability, automobile, homeowners and dwelling policies. The Company markets and sells its insurance products through a network of independent agents and managing general agents. Policies are written in all 50 states. The Company’s corporate headquarters is located in Birmingham, Michigan with additional office facilities in Florida, Pennsylvania and Tennessee. The Company also generates other revenues through investment income and other income which mainly consists of installment fees and policy issuance fees generally related to the policies we write. We also generate equity earnings from SIA's 50% owned agency (the "Affiliate"). The Affiliate places small commercial risks mainly for alarm and security guard markets. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While management believes the amounts included in the consolidated financial statements reflect management's best estimates and assumptions, actual results may differ from these estimates. Recently Issued Accounting Guidance Effective January 1, 2018, the Company adopted FASB Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities . As a result of adoption of this ASU, equity instruments that do not result in consolidation and are not accounted for under the equity method are measured at fair value and any changes in fair value are recognized in net income. Previously, the Company’s equity securities were classified as available-for-sale and changes in fair value were recorded in other comprehensive income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $1.1 million , net of deferred income taxes of $0.5 million , were reclassified from accumulated other comprehensive income into accumulated deficit. Prior periods have not been recast to conform to the current presentation. See Note 2 ~ Investments for details regarding the change in net unrealized gains on equity securities included in net income for the current quarter ended September 30, 2018 . Effective January 1, 2018, the Company early adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU provides an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, the Company reclassified $77,000 of previously recognized deferred taxes from accumulated other comprehensive income into accumulated deficit as of January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which addresses the financial reporting of leasing transactions. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability will be expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the consolidated statement of cash flows. For finance leases, interest on the lease liability will be recognized separately from the amortization of the right-of-use asset in the consolidated statement of operations and the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the consolidated statement of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. We do not have any financing leases. If the standard were adopted as of September 30, 2018 , approximately $4.4 million of future lease liabilities would be added to our balance sheet with a corresponding right-of-use asset. We have approximately $860,000 of operating lease expenses for the nine months ended September 30, 2018 , and do not expect that there would be a materially different expense upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) , which amends the current methodology and timing for recognizing credit losses. This amendment will replace the current GAAP "incurred loss" methodology for credit losses with a methodology based on expected credit losses. The new guidance will also require expanded consideration of a broader range of reasonable and increased supportable information for the credit loss estimates. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted for years beginning after December 15, 2018. Management is currently evaluating the impact of the guidance. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 840) , which modifies the disclosure requirements for assets and liabilities measured at fair value. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted upon the issuance of this update. Management is currently evaluating the impact of the guidance.

The Company’s sources of net investment income are as follows (dollars in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Debt securities $ 801 $ 733 $ 2,495 $ 2,030 Equity securities 33 44 98 94 Cash and short-term investments 19 64 55 91 Total investment income 853 841 2,648 2,215 Investment expenses (67 ) (73 ) (223 ) (207 ) Net investment income $ 786 $ 768 $ 2,425 $ 2,008 The following table summarizes the gross realized gains and losses from sales or maturities of available-for-sale debt and equity securities (dollars in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Debt securities: Gross realized gains $ 52 $ 29 $ 54 $ 29 Gross realized losses (131 ) (1 ) (146 ) (8 ) Total debt securities (79 ) 28 (92 ) 21 Equity securities: Gross realized gains 84 11 290 40 Gross realized losses (26 ) — (46 ) (30 ) Total equity securities 58 11 244 10 Total net realized investment gains (losses) $ (21 ) $ 39 $ 152 $ 31 Proceeds from the sales of debt securities, maturities and other redemptions (primarily the return of capital) were $23.5 million and $19.5 million for the nine months ended September 30, 2018 and 2017 , respectively. Effective January 1, 2018, the Company adopted ASU No. 2016-01. As a result, equity securities are no longer classified as available for sale with unrealized gains and losses recognized in other comprehensive income; rather, all changes in fair value of equity securities are now recognized in net income. The change in fair value of equity securities included in net income for the three and nine months ended September 30, 2018 , was a $151,000 gain and a $116,000 loss, respectively. Prior periods have not been recast for the adoption of this guidance. The table below summarizes the amortized cost and fair value of available-for-sale debt securities by contractual maturity at September 30, 2018 . Actual maturities may differ from contractual maturities because certain borrowers have the right to call or prepay obligations with or without call or prepayment penalties (dollars in thousands): Amortized Cost Estimated Fair Value Due in one year or less $ 7,009 $ 6,986 Due after one year through five years 35,377 34,818 Due after five years through ten years 12,972 12,578 Due after ten years 8,197 7,999 Securities with contractual maturities 63,555 62,381 Asset-backed securities 24,006 23,841 Mortgage-backed securities 31,320 29,805 Commercial mortgage-backed securities 3,890 3,790 Collateralized mortgage obligations 2,247 2,179 Total debt securities $ 125,018 $ 121,996 At September 30, 2018 and December 31, 2017 , the Insurance Company Subsidiaries had an aggregate of $8.2 million on deposit in trust accounts to meet the deposit requirements of various state insurance departments. At September 30, 2018 and December 31, 2017 , the Company had $41.0 million and $18.4 million , respectively, held in trust accounts to meet collateral requirements with other third-party insurers, relating to various fronting arrangements. There are withdrawal and other restrictions on these deposits, including the type of investments that may be held, however, the Company may generally invest in high-grade bonds and short-term investments and earn interest on the funds.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company’s financial instruments include assets and liabilities carried at fair value, as well as assets and liabilities carried at cost or amortized cost but disclosed at fair value in these consolidated financial statements. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principally most advantageous market for the asset or liability in an orderly transaction between market participants. In determining fair value, the Company applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices from sources independent of the reporting entity (“observable inputs”) and the lowest priority to prices determined by the reporting entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (“unobservable inputs”). The fair value hierarchy is as follows: Level 1 —Valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 —Valuations that are based on observable inputs (other than Level 1 prices) such as quoted prices for similar assets or liabilities at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 —Unobservable inputs that are supported by little or no market activity. The unobservable inputs represent the Company’s best assumption of how market participants would price the assets or liabilities. The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis, classified by the valuation hierarchy as of September 30, 2018 and December 31, 2017 (dollars in thousands): September 30, 2018 Fair Value Measurements Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Debt Securities: U.S. Government $ 15,503 $ — $ 15,503 $ — State and local government 15,756 — 15,756 — Corporate debt 31,122 — 31,122 — Asset-backed securities 23,841 — 23,841 — Mortgage-backed securities 29,805 — 29,805 — Commercial mortgage-backed securities 3,790 — 3,790 — Collateralized mortgage obligations 2,179 — 2,179 — Total debt securities 121,996 — 121,996 — Equity Securities 5,645 5,381 264 — Short-term investments 9,905 9,905 — — Total marketable investments measured at fair value $ 137,546 $ 15,286 $ 122,260 $ — Investments measured at NAV: Investment in limited partnership $ 4,187 Total investments measured at NAV $ 4,187 Total assets measured at fair value $ 141,733 Liabilities: Senior Unsecured Notes * $ 22,000 $ 22,000 $ — $ — Subordinated Notes * 9,907 — — 9,907 Total Liabilities measured at fair value $ 31,907 $ 22,000 $ — $ 9,907 * Carried at cost or amortized cost on the consolidated balance sheet December 31, 2017 Fair Value Measurements Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Debt Securities: U.S. Government $ 17,090 $ — $ 17,090 $ — State and local government 17,503 — 17,503 — Corporate debt 38,908 — 38,908 — Asset-backed securities 23,540 — 23,540 — Mortgage-backed securities 33,458 33,458 Commercial mortgage-backed securities 3,491 3,491 Collateralized mortgage obligations 2,546 2,546 Total debt securities 136,536 — 136,536 — Equity securities 5,627 5,381 246 — Short-term investments 11,427 8,429 2,998 — Total marketable investments measured at fair value $ 153,590 $ 13,810 $ 139,780 $ — Investments measured at NAV: Investment in limited partnership $ 4,060 Total investments measured at NAV $ 4,060 Total assets measured at fair value $ 157,650 Liabilities: Debt * $ 29,888 $ — $ — $ 29,888 Total Liabilities measured at fair value $ 29,888 $ — $ — $ 29,888 * Carried at cost or amortized cost on the consolidated balance sheet Level 1 investments consist of equity securities traded in an active exchange market. The Company uses unadjusted quoted prices for identical instruments to measure fair value. Level 1 also includes money market funds and other interest-bearing deposits at banks, which are reported as short-term investments. The fair value measurements that were based on Level 1 inputs comprise 10.8% of the fair value of the total investment portfolio as of September 30, 2018 . Level 2 investments include debt securities, which consist of U.S. government agency securities, state and local municipal bonds (including those held as restricted securities), corporate debt securities, mortgage-backed and asset-backed securities. The fair value of securities included in the Level 2 category were based on the market values obtained from a third party pricing service that were evaluated using pricing models that vary by asset class and incorporate available trade, bid and other observable market information. The third party pricing service monitors market indicators, as well as industry and economic events. The fair value measurements that were based on Level 2 inputs comprise 86.3% of the fair value of the total investment portfolio as of September 30, 2018 . The Company obtains pricing for each security from independent pricing services, investment managers or consultants to assist in determining fair value for its Level 2 investments. To validate that these quoted prices are reasonable estimates of fair value, the Company performs various quantitative and qualitative procedures, such as (i) evaluation of the underlying methodologies, (ii) analysis of recent sales activity, (iii) analytical review of our fair values against current market prices and (iv) comparison of the pricing services’ fair value to other pricing services’ fair value for the same investment. No markets for the investments were determined to be inactive at period-ends. Based on these procedures, the Company did not adjust the prices or quotes provided from independent pricing services, investment managers or consultants. As of September 30, 2018 , Level 3 is entirely comprised of the Company's subordinated debt. In determining the fair value of the subordinated debt outstanding at September 30, 2018 , the security attributes (issue date, maturity, coupon, calls, etc.) and market rates on September 29, 2017 (the date of issuance) were fed into a valuation model. A lognormal trinomial interest rate lattice was created within the model to compute the option adjusted spread (“OAS”) which is the amount, in basis points, of interest rate required to be paid under the debt agreement over the risk-free U.S. Treasury rates. The OAS was then fed back into the model along with the September 30, 2018 , U.S. Treasury rates. A new lattice was generated and the fair value was computed from the OAS. There were no changes in assumptions of credit risk from the issuance date. The Company’s policy on recognizing transfers between hierarchy levels is applied at the end of each reporting period. There were no transfers between Levels 1, 2 and 3 for the nine months ended September 30, 2018 and 2017 , respectively.

Deferred Policy Acquisition Costs Disclosures [Abstract]
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs The Company defers costs incurred which are incremental and directly related to the successful acquisition of new or renewal insurance business, net of corresponding amounts of ceded reinsurance commissions. Net deferred policy acquisition costs are amortized and charged to expense in proportion to premium earned over the estimated policy term. The Company anticipates that its deferred policy acquisition costs will be fully recoverable and there were no premium deficiencies for the nine months ended September 30, 2018 and 2017 . The activity in deferred policy acquisition costs, net of reinsurance transactions, is as follows (dollars in thousands): Three Months Ended Nine Months Ended 2018 2017 2018 2017 Balance at beginning of period $ 12,021 $ 12,649 $ 12,781 $ 13,290 Deferred policy acquisition costs 6,274 6,759 18,499 19,018 Amortization of policy acquisition costs (6,452 ) (6,655 ) (19,437 ) (19,555 ) Net change (178 ) 104 (938 ) (537 ) Balance at end of period $ 11,843 $ 12,753 $ 11,843 $ 12,753

Unpaid Losses and Loss Adjustme

Insurance Loss Reserves [Abstract]
Unpaid Losses and Loss Adjustment Expenses	Unpaid Losses and Loss Adjustment Expenses The Company establishes reserves for unpaid losses and loss adjustment expenses ("LAE") which represent the estimated ultimate cost of all losses incurred that were both reported and unreported (i.e., incurred but not yet reported losses; or “IBNR”) and LAE incurred that remain unpaid at the balance sheet date. The Company’s reserving process takes into account known facts and interpretations of circumstances and factors including the Company’s experience with similar cases, actual claims paid, historical trends involving claim payment patterns and pending levels of unpaid claims, loss management programs, product mix and contractual terms, changes in law and regulation, judicial decisions, and economic conditions. In the normal course of business, the Company may also supplement its claims processes by utilizing third party adjusters, appraisers, engineers, inspectors, and other professionals and information sources to assess and settle catastrophe and non-catastrophe related claims. The effects of inflation are implicitly considered in the reserving process. Reserves are estimates of unpaid portions of losses that have occurred, including IBNR losses; therefore the establishment of appropriate reserves is an inherently uncertain and complex process. The ultimate cost of losses may vary materially from recorded amounts, which are based on management’s best estimates. The highest degree of uncertainty is associated with reserves for losses incurred in the current reporting period as it contains the greatest proportion of losses that have not been reported or settled. The Company regularly updates its reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in reserve estimates, which may be material, are reported in the results of operations in the period such changes are determined to be needed and recorded. Management believes that the reserve for losses and LAE, net of reinsurance recoverables, is appropriately established in the aggregate and adequate to cover the ultimate net cost of reported and unreported claims arising from losses which had occurred by the date of the consolidated financial statements based on available facts and in accordance with applicable laws and regulations. The table below provides the changes in the reserves for losses and LAE, net of reinsurance recoverables, for the periods indicated as follows (dollars in thousands): Three Months Ended Nine Months Ended 2018 2017 2018 2017 Gross reserves - beginning of period $ 83,662 $ 66,917 $ 87,896 $ 54,651 Less: reinsurance recoverables on unpaid losses 20,467 10,552 20,066 6,658 Plus: deferred gain on ADC (2,412 ) — — — Net reserves - beginning of period 65,607 56,365 67,830 47,993 Add: incurred losses and LAE, net of reinsurance: Current period 13,153 24,398 40,079 49,449 Prior period 3,401 2,070 4,871 9,426 Total net incurred losses and LAE 16,554 26,468 44,950 58,875 Deduct: loss and LAE payments, net of reinsurance: Current period 5,423 7,194 11,448 14,410 Prior period 7,877 6,411 32,471 23,230 Total net loss and LAE payments 13,300 13,605 43,919 37,640 Net reserves - end of period 68,861 69,228 68,861 69,228 Plus: reinsurance recoverables on unpaid losses 27,118 13,528 27,118 13,528 Less: deferred gain on ADC (4,933 ) — (4,933 ) — Gross reserves - end of period $ 91,046 $ 82,756 $ 91,046 $ 82,756 On September 28, 2017, the Company entered into an adverse development cover reinsurance agreement (the "ADC") to cover loss development of up to $17.5 million in excess of stated reserves as of June 30, 2017. The agreement provides up to $17.5 million of reinsurance for adverse net loss reserve development for accident years 2005 through 2016. The agreement attaches when net losses exceed $1.4 million of the $36.6 million carried reserves at June 30, 2017, and extends to $19.5 million in coverage up to $57.5 million (inclusive of a 10% co-participation). The Company accounts for the agreement as retroactive reinsurance. For the three and nine months ended September 30, 2018 , the Company recorded $4.1 million and $7.3 million of net adverse loss development covered under this agreement, which increased the retroactive reinsurance recoverable to $14.5 million , leaving $3.0 million of coverage remaining on the ADC. The Company recorded the retroactive reinsurance recoverable in excess of the consideration as a deferred gain that is amortized to earnings using the interest method over the estimated claims settlement period. As of September 30, 2018 , the deferred gain of $4.9 million , net of amortization, is included in Other Liabilities on the consolidated balance sheets. The Company’s incurred losses during the three and nine months ended September 30, 2018 , included adverse prior-year reserve development of $3.4 million and $4.9 million , respectively. Before the effect of the ADC deferred gain, the commercial lines of business reported $4.2 million of adverse prior-year development and personal lines reported $612,000 of adverse development for the three months ended September 30, 2018 . Before the effect of the ADC deferred gain, the commercial lines of business reported $5.3 million of adverse prior-year development and personal lines reported $1.9 million of adverse development for the nine months ended September 30, 2018 . Included in the unfavorable development was $83,000 and $471,000 attributable to additional 2017 losses from Hurricane Harvey for the three and nine months ended September 30, 2018 , respectively. The ADC had a favorable impact of $1.5 million and $2.4 million on prior year reserve development for the three and nine months ended September 30, 2018 , respectively. The Company’s incurred losses during the three and nine months ended September 30, 2017, included prior-year adverse reserve development of $2.1 million and $9.4 million , respectively. The $2.1 million of net adverse development was comprised of $865,000 from the commercial liability line of business, $697,000 from the Florida homeowners line, $604,000 from the commercial auto line of business, $350,000 from the commercial property line, offset by $446,000 of favorable development from other lines. For the nine months ended September 30, 2017, there was adverse development of $4.2 million from the commercial liability line of business, $2.4 million from the Florida homeowners line, $2.2 million from the commercial property line, $932,000 from the commercial auto line of business, offset by $277,000 of favorable development in other lines.

Reinsurance Disclosures [Abstract]
Reinsurance	Reinsurance In the normal course of business, the Company seeks to minimize the loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with reinsurers. The Company participates in reinsurance agreements in order to limit its loss exposure including protecting against catastrophe losses. The Company primarily ceded all specific property risks in excess of $300,000 in 2018 and $500,000 in 2017 and primarily ceded all specific liability risks in excess of $500,000 in both 2018 and 2017. Reinsurance does not discharge the direct insurer from liability to its policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial condition of its reinsurers and monitors the concentration of credit risk arising from similar geographic regions, activities, or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. To date, the Company has not experienced any significant difficulties in collecting reinsurance recoverables. The Company assumes written premiums under a few fronting arrangements, most of which are net of other reinsurance arrangements. The fronting arrangements are with unaffiliated insurers who write on behalf of the Company in markets that require a higher A.M. Best rating than the Company’s current rating, where the policies are written in a state where the Company is not licensed or for other strategic reasons. The consideration for the ADC entered into in the third quarter of 2017 was a payment of $7.2 million , which resulted in a one-time charge to ceded premiums fully earned in the third quarter of 2017. There is a 35% contingent recovery depending on the performance of the reserves over time. No recovery is currently reflected in the financial statements. The following table presents the effects of such reinsurance and assumption transactions on premiums and losses and LAE (dollars in thousands). The 2018 ceded written and earned premium amounts include $257,000 and $797,000 of reinsurance reinstatement costs relating to Hurricane Irma for the three and nine months ended September 30, 2018 , respectively.

Debt	Debt The Company's debt is comprised of three instruments: $22.0 million of senior unsecured notes which were issued in September 2018, a $10.0 million line of credit which commenced in June 2018, and $30.0 million of subordinated notes which commenced in September 2017. A summary of the Company's outstanding debt is as follows (dollars in thousands): September 30, 2018 December 31, 2017 Senior unsecured notes $ 20,779 $ — Subordinated notes 8,971 29,027 Line of credit — — Total $ 29,750 $ 29,027 On September 24, 2018, the Company issued $22.0 million of senior unsecured notes (the "Notes"). The Notes bear interest at the rate of 6.75% per year, and interest on the Notes is payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, beginning on December 31, 2018. The Notes will mature on September 30, 2023. The Company may redeem the Notes, in whole or in part at any time or from time to time on or after September 30, 2021, at the redemption price of 100% aggregate principal amount, plus any accrued and unpaid interest. $20.0 million of the proceeds from the Notes were used to pay off the Company's private placement subordinated notes (the "Subordinated Notes"). On June 21, 2018, the Company entered into a $10.0 million line of credit. The agreement has a maturity date of June 21, 2019 and bears interest at the London Interbank rate ("LIBOR") plus 2.75% per annum, payable monthly. The agreement includes several covenants, including but not limited to a minimum tangible net worth, a minimum fixed-charge coverage ratio, and minimum statutory risk-based capital levels. As of September 30, 2018 , the Company has not drawn down on the line of credit. On September 29, 2017, the Company executed $30.0 million of Subordinated Notes. The Subordinated Notes have a maturity date of September 29, 2032, bear interest, payable quarterly at a fixed annual rate of 8.0% , and allow for up to four quarterly interest deferrals. On the fifth and tenth anniversary of the Subordinated Notes, the interest rate resets to 1,250 basis points and 1,500 basis points, respectively, above the 5 -year mid-swap rate. The Company paid down $20.0 million of the Subordinated Notes in September 2018. The carrying value of the Notes and Subordinated Notes are offset by $1.2 million and $1.0 million of debt issuance costs, respectively. The debt issuance costs will be amortized through interest expense over the life of the loans. The Subordinated Notes contain various restrictive covenants that relate to the Company’s tangible net worth, fixed-charge coverage ratios, dividend paying capacity, reinsurance retentions, and risk-based capital ratios. At September 30, 2018 , the Company was in compliance with all of its financial covenants.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity In September 2017, the Company issued $5.0 million of common equity through a private placement for 800,000 shares priced at $6.25 per share. The participants in the private placement consisted mainly of members of the Company’s management team and insiders, including Chairman and CEO James Petcoff. The Company used the proceeds to strengthen its balance sheet through contributions to the subsidiaries to support their future growth, as well as cover the cost of the ADC and reserve strengthening. On February 25, 2016, the Company's Board of Directors authorized a stock repurchase program, under which the Company may repurchase up to $2.1 million of its outstanding common stock. Under this program, management was authorized to repurchase shares at prevailing market prices through open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b5-1 and 10b-18 of the Securities Exchange Act of 1934, as amended. The actual timing, number and value of shares repurchased under the program was determined by management in its discretion and depends on a number of factors, including the market price of the Company’s stock, general market conditions, and other factors. For the nine months ended September 30, 2018 and 2017, the Company had not repurchased any shares of stock. Repurchased shares remain authorized but not issued or outstanding, and are available to be reissued in the future. As of September 30, 2018 and December 31, 2017, the Company had 8,602,703 and 8,520,328 issued and outstanding shares of common stock, respectively. Holders of common stock are entitled to one vote per share and to receive dividends only when and if declared by the board of directors. The holders have no preemptive, conversion or subscription rights.

Stock-based Compensation	Stock-based Compensation In 2015, the Company issued 390,352 restricted stock units ("RSUs") to executive officers and other employees to be settled in shares of common stock. The total RSUs were valued at $4.1 million on the dates of grant. In 2016, the Company issued 111,281 RSUs to executive officers and other employees valued at $909,000 on the date of grant. In 2018, the Company issued 70,000 RSUs to executive officers and other employees valued at $404,000 on the dates of grant. The following summarizes our RSU activity (units in thousands): Number of Units Weighted Average Grant-Date Fair Value Outstanding at December 31, 2016 416 $ 9.87 Units vested (93 ) 9.97 Units forfeited (14 ) 9.95 Outstanding at September 30, 2017 309 $ 9.84 Units vested (2 ) 9.56 Outstanding at December 31, 2017 307 $ 9.84 Units granted 70 5.76 Units vested (89 ) 10.02 Units forfeited (15 ) 8.81 Outstanding at September 30, 2018 273 $ 8.79 The Company recorded $716,000 and $650,000 of compensation expense related to the RSUs for the nine months ended September 30, 2018 and 2017 , respectively. The total compensation cost related to the non-vested portion of the restricted stock units which has not been recognized as of September 30, 2018 , was $2.2 million .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal proceedings The Company and its subsidiaries are subject at times to various claims, lawsuits and proceedings relating principally to alleged errors or omissions in the placement of insurance, claims administration, and other business transactions arising in the ordinary course of business. Where appropriate, the Company vigorously defends such claims, lawsuits and proceedings. Some of these claims, lawsuits and proceedings seek damages, including consequential, exemplary or punitive damages, in amounts that could, if awarded, be significant. Most of the claims, lawsuits and proceedings arising in the ordinary course of business are related to the insurance policy issued. On the basis of current information, the Company does not believe that there is a reasonable possibility that any material loss exceeding amounts already accrued, if any, will result from any of the claims, lawsuits and proceedings to which the Company is subject, either individually, or in the aggregate.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company is engaged in the sale of property and casualty insurance products and has organized its business model around two classes of insurance businesses: commercial and personal lines. Within these two insurance businesses, the Company offers various insurance products. Such insurance businesses are engaged in underwriting and marketing insurance coverages, and administering claims processing for such policies. The Company defines its operating segments as components of the business where separate financial information is available and used by the chief operating decision-making group in deciding how to allocate resources to its segments and in assessing its performance. In assessing performance of its operating segments, the Company’s chief operating decision-making group, comprised of key senior executives, reviews a number of financial measures including gross written premiums, net earned premiums and losses and LAE, net of reinsurance recoveries. The primary measure used for making decisions about resources to be allocated to an operating segment and assessing its performance is segment underwriting gain or loss which is defined as segment revenues, consisting of net earned premiums and other income, less segment expenses, consisting of losses and LAE, policy acquisition costs and operating expenses of the operating segments. Operating expenses primarily include compensation and related benefits for underwriting personnel, policy issuance and claims systems, rent and utilities. The Company markets, distributes and sells its insurance products through its own insurance agencies and a network of independent agents. All of the Company’s insurance activities are conducted in the United States with a concentration of activity in Florida, Michigan, Texas and Pennsylvania. For the nine months ended September 30, 2018 and 2017 , gross written premiums attributable to these four states were 54% and 60% , respectively, of the Company’s total gross written premiums. In addition to the reportable operating segments, the Company maintains a Corporate and Other category to reconcile segment results to the consolidated totals. The Corporate and Other category includes: (i) corporate operating expenses such as salaries and related benefits of the Company’s executive management team and finance and information technology personnel, and other corporate headquarters expenses, (ii) interest expense on the Company’s debt obligations; (iii) depreciation and amortization on property and equipment, and (iv) all investment income activity. All investment income activity is reported within net investment income and net realized investment gains on the consolidated statements of operations. The Company’s assets on the consolidated balance sheet are not allocated to the reportable segments. The following tables present information by reportable operating segment (dollars in thousands): Three Months Ended September 30, 2018 Commercial Lines Personal Lines Corporate & Other Total Gross written premiums $ 24,806 $ 1,823 $ — $ 26,629 Net written premiums $ 22,160 $ 686 $ — $ 22,846 Net earned premiums $ 21,270 $ 2,180 $ — $ 23,450 Other income 167 199 39 405 Total revenue 21,437 2,379 39 23,855 Losses and loss adjustment expenses, net 14,445 2,109 — 16,554 Policy acquisition costs 5,441 1,011 — 6,452 Operating expenses 3,969 416 401 4,786 Total expenses 23,855 3,536 401 27,792 Underwriting gain (loss) $ (2,418 ) $ (1,157 ) $ (362 ) $ (3,937 ) Net investment income 786 786 Net realized investment gains (21 ) (21 ) Change in fair value of equity securities 151 151 Interest expense (598 ) (598 ) Income (loss) before equity earnings of affiliates and income taxes $ (44 ) $ (3,619 ) Three Months Ended September 30, 2017 Commercial Lines Personal Lines Corporate & Other Total Gross written premiums $ 23,509 $ 6,072 $ — $ 29,581 Net written premiums $ 16,221 $ 2,174 $ — $ 18,395 Net earned premiums $ 15,658 $ 2,001 $ — $ 17,659 Other income 162 281 34 477 Total revenue 15,820 2,282 34 18,136 Losses and loss adjustment expenses, net 19,589 6,879 — 26,468 Policy acquisition costs 5,161 1,494 — 6,655 Operating expenses 3,322 808 344 4,474 Total expenses 28,072 9,181 344 37,597 Underwriting gain (loss) $ (12,252 ) $ (6,899 ) (310 ) (19,461 ) Net investment income 768 768 Net realized investment gains 39 39 Interest expense (303 ) (303 ) Income (loss) before equity earnings of affiliates and income taxes $ 194 $ (18,957 ) Nine Months Ended September 30, 2018 Commercial Lines Personal Lines Corporate & Other Total Gross written premiums $ 71,602 $ 5,326 $ — $ 76,928 Net written premiums $ 63,866 $ 1,420 $ — $ 65,286 Net earned premiums $ 62,270 $ 8,918 $ — $ 71,188 Other income 471 593 148 1,212 Total revenue 62,741 9,511 148 72,400 Losses and loss adjustment expenses, net 36,979 7,971 — 44,950 Policy acquisition costs 16,028 3,409 — 19,437 Operating expenses 11,294 1,134 848 13,276 Total expenses 64,301 12,514 848 77,663 Underwriting gain (loss) $ (1,560 ) $ (3,003 ) (700 ) (5,263 ) Net investment income 2,425 2,425 Net realized investment gains 152 152 Change in fair value of equity securities (116 ) (116 ) Interest Expense (1,834 ) (1,834 ) Income (loss) before equity earnings of affiliates and income taxes $ (73 ) $ (4,636 ) Nine Months Ended September 30, 2017 Commercial Lines Personal Lines Corporate & Other Total Gross written premiums $ 66,258 $ 16,778 $ — $ 83,036 Net written premiums $ 54,616 $ 9,185 $ — $ 63,801 Net earned premiums $ 55,443 $ 10,852 $ — $ 66,295 Other income 485 601 117 1,203 Total revenue 55,928 11,453 117 67,498 Losses and loss adjustment expenses, net 43,819 15,056 — 58,875 Policy acquisition costs 15,180 4,375 — 19,555 Operating expenses 8,231 1,967 3,176 13,374 Total expenses 67,230 21,398 3,176 91,804 Underwriting gain (loss) $ (11,302 ) $ (9,945 ) (3,059 ) (24,306 ) Net investment income 2,008 2,008 Net realized investment gains (losses) 31 31 Other gains 750 750 Interest expense (745 ) (745 ) Income (loss) before equity earnings of affiliates and income taxes $ (1,015 ) $ (22,262 )

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On October 12, 2018 the Company announced that the underwriters for the previously announced public offering of the Company’s 6.75% Senior Unsecured Notes due 2023 exercised in full their over-allotment option to purchase an additional $3.3 million aggregate principal amount of the Notes. The total aggregate principal amount of Notes sold by the Company in the offering increased to $25.3 million . The principal amount of the Notes is offset by approximately $1.4 million of debt issuance costs for a net carrying value of $23.9 million . Refer to Note 7 ~ Debt for further details of the previously announced public offering. On November 2, 2018, the Company amended the terms of the Subordinated Notes. Under the new terms, the Subordinated Notes carry a principle value of $10.5 million and mature on September 30, 2038. The Subordinated Notes bear an annual interest rate of 7.5% until September 30, 2023, and 12.5% thereafter. Interest is payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, beginning on December 31, 2018. Beginning September 30, 2021, the Company may redeem the Subordinated Notes, in whole or in part, or any quarter thereafter, for a call premium of $1.1 million on September 30, 2021. The call premium escalates quarterly to $1.75 million on September 30, 2023, then steps up to $3.05 million on December 31, 2023, and increases quarterly at a 12.5% per annum rate thereafter. The debt covenants are consistent with the existing Subordinated Note terms. A $105,000 loan origination fee was paid on the effective date.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include accounts, after elimination of intercompany accounts and transactions, of Conifer Holdings, Inc. (the “Company” or “Conifer”), its wholly owned subsidiaries, Conifer Insurance Company ("CIC"), White Pine Insurance Company ("WPIC"), Red Cedar Insurance Company ("RCIC"), and Sycamore Insurance Agency, Inc. ("SIA"). CIC, WPIC, and RCIC are collectively referred to as the "Insurance Company Subsidiaries." On a stand-alone basis, Conifer Holdings, Inc. is referred to as the "Parent Company." The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company has applied the rules and regulations of the United States Securities and Exchange Commission (“SEC”) regarding interim financial reporting and therefore the consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments, consisting of items of a normal recurring nature, necessary for a fair presentation of the consolidated interim financial statements, have been included. The results of operations for the nine months ended September 30, 2018 , are not necessarily indicative of the results expected for the year ended December 31, 2018 . These consolidated financial statements and the notes thereto should be read in conjunction with the Company's audited consolidated financial statements and related notes included in its Annual Report on Form 10-K/A for the year ended December 31, 2017 , as filed with the SEC.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While management believes the amounts included in the consolidated financial statements reflect management's best estimates and assumptions, actual results may differ from these estimates.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance Effective January 1, 2018, the Company adopted FASB Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities . As a result of adoption of this ASU, equity instruments that do not result in consolidation and are not accounted for under the equity method are measured at fair value and any changes in fair value are recognized in net income. Previously, the Company’s equity securities were classified as available-for-sale and changes in fair value were recorded in other comprehensive income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $1.1 million , net of deferred income taxes of $0.5 million , were reclassified from accumulated other comprehensive income into accumulated deficit. Prior periods have not been recast to conform to the current presentation. See Note 2 ~ Investments for details regarding the change in net unrealized gains on equity securities included in net income for the current quarter ended September 30, 2018 . Effective January 1, 2018, the Company early adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU provides an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, the Company reclassified $77,000 of previously recognized deferred taxes from accumulated other comprehensive income into accumulated deficit as of January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which addresses the financial reporting of leasing transactions. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability will be expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the consolidated statement of cash flows. For finance leases, interest on the lease liability will be recognized separately from the amortization of the right-of-use asset in the consolidated statement of operations and the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the consolidated statement of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. We do not have any financing leases. If the standard were adopted as of September 30, 2018 , approximately $4.4 million of future lease liabilities would be added to our balance sheet with a corresponding right-of-use asset. We have approximately $860,000 of operating lease expenses for the nine months ended September 30, 2018 , and do not expect that there would be a materially different expense upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) , which amends the current methodology and timing for recognizing credit losses. This amendment will replace the current GAAP "incurred loss" methodology for credit losses with a methodology based on expected credit losses. The new guidance will also require expanded consideration of a broader range of reasonable and increased supportable information for the credit loss estimates. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted for years beginning after December 15, 2018. Management is currently evaluating the impact of the guidance. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 840) , which modifies the disclosure requirements for assets and liabilities measured at fair value. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted upon the issuance of this update. Management is currently evaluating the impact of the guidance.
Fair Value Measurements	Level 1 investments consist of equity securities traded in an active exchange market. The Company uses unadjusted quoted prices for identical instruments to measure fair value. Level 1 also includes money market funds and other interest-bearing deposits at banks, which are reported as short-term investments. The fair value measurements that were based on Level 1 inputs comprise 10.8% of the fair value of the total investment portfolio as of September 30, 2018 . Level 2 investments include debt securities, which consist of U.S. government agency securities, state and local municipal bonds (including those held as restricted securities), corporate debt securities, mortgage-backed and asset-backed securities. The fair value of securities included in the Level 2 category were based on the market values obtained from a third party pricing service that were evaluated using pricing models that vary by asset class and incorporate available trade, bid and other observable market information. The third party pricing service monitors market indicators, as well as industry and economic events. The fair value measurements that were based on Level 2 inputs comprise 86.3% of the fair value of the total investment portfolio as of September 30, 2018 . The Company obtains pricing for each security from independent pricing services, investment managers or consultants to assist in determining fair value for its Level 2 investments. To validate that these quoted prices are reasonable estimates of fair value, the Company performs various quantitative and qualitative procedures, such as (i) evaluation of the underlying methodologies, (ii) analysis of recent sales activity, (iii) analytical review of our fair values against current market prices and (iv) comparison of the pricing services’ fair value to other pricing services’ fair value for the same investment. No markets for the investments were determined to be inactive at period-ends. Based on these procedures, the Company did not adjust the prices or quotes provided from independent pricing services, investment managers or consultants. As of September 30, 2018 , Level 3 is entirely comprised of the Company's subordinated debt. In determining the fair value of the subordinated debt outstanding at September 30, 2018 , the security attributes (issue date, maturity, coupon, calls, etc.) and market rates on September 29, 2017 (the date of issuance) were fed into a valuation model. A lognormal trinomial interest rate lattice was created within the model to compute the option adjusted spread (“OAS”) which is the amount, in basis points, of interest rate required to be paid under the debt agreement over the risk-free U.S. Treasury rates. The OAS was then fed back into the model along with the September 30, 2018 , U.S. Treasury rates. A new lattice was generated and the fair value was computed from the OAS. There were no changes in assumptions of credit risk from the issuance date. The Company’s policy on recognizing transfers between hierarchy levels is applied at the end of each reporting period. There were no transfers between Levels 1, 2 and 3 for the nine months ended September 30, 2018 and 2017 , respectively. The Company’s financial instruments include assets and liabilities carried at fair value, as well as assets and liabilities carried at cost or amortized cost but disclosed at fair value in these consolidated financial statements. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principally most advantageous market for the asset or liability in an orderly transaction between market participants. In determining fair value, the Company applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices from sources independent of the reporting entity (“observable inputs”) and the lowest priority to prices determined by the reporting entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (“unobservable inputs”). The fair value hierarchy is as follows: Level 1 —Valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 —Valuations that are based on observable inputs (other than Level 1 prices) such as quoted prices for similar assets or liabilities at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 —Unobservable inputs that are supported by little or no market activity. The unobservable inputs represent the Company’s best assumption of how market participants would price the assets or liabilities.
