Basis of Presentation [Abstract]
Basis of Presentation	2. Basis of Presentation  Our unaudited consolidated financial statements included herein have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include our accounts and the accounts of our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2017 included in our Annual Report on Form 10-K filed with the SEC.  The interim financial data as of March 31, 2018 and 2017 is unaudited. However, in the opinion of management, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The results of operations for the period ended March 31, 2018 are not necessarily indicative of the operating results to be expected for the full year.   Reclassifications  Certain prior year amounts have been reclassified to conform with current year presentation.  Income Taxes  We file a consolidated federal income tax return. Deferred federal income taxes reflect the future tax consequences of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end. Deferred taxes are recognized using the liability method, whereby tax rates are applied to cumulative temporary differences based on when and how they are expected to affect the tax return. Deferred tax assets and liabilities are adjusted for tax rate changes in effect for the year in which these temporary differences are expected to be recovered or settled.  Use of Estimates in the Preparation of the Financial Statements  Our preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect our reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting period. Refer to “Critical Accounting Estimates and Judgments” under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2017 for information on accounting policies that we consider critical in preparing our consolidated financial statements. Actual results could differ materially from those estimates.  Fair Value of Financial Instruments  Fair value estimates are made at a point in time based on relevant market data as well as the best information available about the financial instruments. Fair value estimates for financial instruments for which no or limited observable market data is available are based on judgments regarding current economic conditions, credit and interest rate risk. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the instrument. In addition, changes in the underlying assumptions used in the fair value measurement technique, including discount rate and estimates of future cash flows, could significantly affect these fair value estimates.  Cash and Cash Equivalents : The carrying amounts reported in the balance sheet for these instruments approximate their fair values.  Restricted Cash : The carrying amount for restricted cash reported in the balance sheet approximates the fair value.  Revolving Credit Facility Payable : A revolving credit facility with Frost Bank had a carried value of $30.0 million and a fair value of $30.2 million as of March 31, 2018 . The fair value is based on discounted cash flows using a discount rate derived from LIBOR spot rates plus a market spread resulting in discount rates ranging between 4.4 % to 4.8 % for each future payment date. This revolving credit facility would be included in Level 3 of the fair value hierarchy if it was reported at fair value.  Subordinated Debt Securities : Our trust preferred securities have a carried value of $55.8 million and a fair value of $ 45.5 million as of March 31, 2018. The fair value of our trust preferred securities is based on discounted cash flows using a current yield to maturity of 8.0% , which is based on similar issues to discount future cash flows. Our trust preferred securities would be included in Level 3 of the fair value hierarchy if they were reported at fair value.  For reinsurance balances, premiums receivable, federal income tax recoverable, other assets and other liabilities, the carrying amounts approximate fair value because of the short maturity of such financial instruments.  Variable Interest Entities  On June 21, 2005, we formed Hallmark Statutory Trust I (“Trust I”), an unconsolidated trust subsidiary, for the sole purpose of issuing $30.0 million in trust preferred securities. Trust I used the proceeds from the sale of these securities and our initial capital contribution to purchase $30.9 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust I, and the payments under the debt securities are the sole revenues of Trust I.  On August 23, 2007, we formed Hallmark Statutory Trust II (“Trust II”), an unconsolidated trust subsidiary, for the sole purpose of issuing $25.0 million in trust preferred securities. Trust II used the proceeds from the sale of these securities and our initial capital contribution to purchase $25.8 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust II, and the payments under the debt securities are the sole revenues of Trust II.  We evaluate on an ongoing basis our investments in Trust I and Trust II (collectively the “Trusts”) and have determined that we do not have a variable interest in the Trusts. Therefore, the Trusts are not included in our consolidated financial statements.  We are also involved in the normal course of business with variable interest entities (“VIE’s”) primarily as a passive investor in mortgage-backed securities and certain collateralized corporate bank loans issued by third party VIE’s. The maximum exposure to loss with respect to these investments is the investment carrying values included in the consolidated balance sheets.  Adoption of New Accounting Pronouncements   In January 2017, the FASB issued ASU 2017-01, “Clarifying the Definition of a Business” (Topic 715). ASU 2017-01 is intended to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  On February 14, 2018, the FASB issued updated guidance that allows a reclassification of the stranded tax effects in accumulated other comprehensive income (AOCI) resulting from the Tax Cuts and Jobs Act of 2017 (TCJA). Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of TCJA related to items in AOCI. The updated guidance was effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the TCJA related to items remaining in AOCI are recognized or at the beginning of the period of adoption. Early adoption is permitted. The Company adopted the updated guidance effective January 1, 2018 and elected to reclassify the income tax effects of the TCJA from AOCI to retained earnings as of January 1, 2018. This reclassification resulted in a decrease in retained earnings of $2.6 million as of January 1, 2018 and an increase in AOCI by the same amount.  In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (Subtopic 825-10). ASU 2016-01 will require equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. ASU 2016-01 will also require us to assess the ability to realize our deferred tax assets (“DTAs”) related to an available-for-sale debt security in combination with our other DTAs. ASU 2016-01 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this guidance resulted in the recognition of $17.0 million of net after-tax unrealized gains on equity investments as a cumulative effect adjustment that increased retained earnings as of January 1, 2018 and decreased AOCI by the same amount. The Company elected to report changes in the fair value of equity investments in investment gains and (losses) in the Consolidated Statement of Operations. At December 31, 2017, equity investments were classified as available-for-sale on the Company's balance sheet. However, upon adoption, the updated guidance eliminated the available-for-sale balance sheet classification for equity investments .  In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (Topic 230). ASU 2016-15 will reduce diversity in practice on how eight specific cash receipts and payments are classified on the statement of cash flows. The ASU will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The purpose of ASU 2016-18 is to eliminate the diversity in classifying and presenting changes in restricted cash in the statement of cash flows. The new guidance requires restricted cash to be combined with cash and cash equivalents when reconciling the beginning and ending balances of cash on the statement of cash flows, thereby no longer requiring transactions such as transfers between restricted and unrestricted cash to be treated as a cash flow activity. Further, the new guidance requires the nature of the restrictions to be disclosed, as well as a reconciliation between the balance sheet and the statement of cash flows on how restricted and unrestricted cash are segregated. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within that fiscal year, with early adoption permitted. Effective January 1, 2018, we retrospectively adopted this new guidance.  In May 2014, the FASB issued guidance which revises the criteria for revenue recognition. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies the performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs. The guidance was effective for reporting periods beginning after December 15, 2017 and is to be applied retrospectively. Revenue from insurance contracts is excluded from the scope of this new guidance. While insurance contracts are excluded from this guidance, policy fee income, billing and other fees and fee income related to property business written as a cover-holder through a Lloyds Syndicate will be subject to this updated guidance. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  Recently Issued Accounting Pronouncements  In March 2017, the FASB issued ASU 2017-08, “Premium Amortization on Purchased Callable Securities” (Subtopic 310-20). ASU 2017-08 is intended to enhance the accounting for amortization of premiums for purchased callable debt securities. The guidance amends the amortization period for certain purchased callable debt securities held at a premium. Securities that contain explicit, noncontingent call features that are callable at fixed prices and on preset dates should shorten the amortization period for the premium to the earliest call date (and if the call option is not exercised, the effective yield is reset using the payment terms of the debt security). The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings. We are currently evaluating the impact that the adoption of ASU 2017-08 will have on our financial results and disclosures. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (Topic 350). ASU 2017-04 requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We are currently evaluating the impact that the adoption of ASU 2017-04 will have on our financial results and disclosures.  In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016-13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. ASU 2016-13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures, but do not anticipate that any potential impact would be material.  In February 2016, the FASB issued ASU 2016-02, “Leases” (Topic 842). ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, ASU 2016-02 modifies current guidance for lessors' accounting. ASU 2016-02 is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. We do not anticipate that this standard will have a material impact on our results of operations, but we anticipate an increase to the value of our assets and liabilities related to leases, with no material impact to equity.

Fair Value [Abstract]
Fair Value	3. Fair Value  ASC 820 defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. ASC 820, among other things, requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In addition, ASC 820 precludes the use of block discounts when measuring the fair value of instruments traded in an active market, which were previously applied to large holdings of publicly traded equity securities.  We determine the fair value of our financial instruments based on the fair value hierarchy established in ASC 820. In accordance with ASC 820, we utilize the following fair value hierarchy: · Level 1: quoted prices in active markets for identical assets;  · Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, inputs of identical assets for less active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument; and  · Level 3: inputs to the valuation methodology that are unobservable for the asset or liability.  This hierarchy requires the use of observable market data when available.  Under ASC 820, we determine fair value based on the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy described above. Fair value measurements for assets and liabilities where there exists limited or no observable market data are calculated based upon our pricing policy, the economic and competitive environment, the characteristics of the asset or liability and other factors as appropriate. These estimated fair values may not be realized upon actual sale or immediate settlement of the asset or liability.  Where quoted prices are available on active exchanges for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include common and preferred stock and an equity warrant classified as Other Investments.  Level 2 investment securities include corporate bonds, collateralized corporate bank loans, municipal bonds, U.S. Treasury securities, other obligations of the U.S. Government and mortgage-backed securities for which quoted prices are not available on active exchanges for identical instruments. We use third party pricing services to determine fair values for each Level 2 investment security in all asset classes. Since quoted prices in active markets for identical assets are not available, these prices are determined using observable market information such as quotes from less active markets and/or quoted prices of securities with similar characteristics, among other things. We have reviewed the processes used by the pricing services and have determined that they result in fair values consistent with the requirements of ASC 820 for Level 2 investment securities. We have not adjusted any prices received from third party pricing sources. There were no transfers between Level 1 and Level 2 securities.  In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy. Level 3 investments are valued based on the best available data in order to approximate fair value. This data may be internally developed and consider risk premiums that a market participant would require. Investment securities classified within Level 3 include other less liquid investment securities.        The following table presents for each of the fair value hierarchy levels, our assets that are measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017 (in thousands):     As of March 31, 2018  Quoted Prices in Other  Active Markets for Observable Unobservable  Identical Assets Inputs Inputs  (Level 1) (Level 2) (Level 3) Total  U.S. Treasury securities and obligations of U.S. Government $ - $ 49,418 $ - $ 49,418  Corporate bonds - 255,880 305 256,185  Collateralized corporate bank loans - 138,407 - 138,407  Municipal bonds - 134,292 2,896 137,188  Mortgage-backed - 14,648 - 14,648  Total debt securities - 592,645 3,201 595,846   Total equity securities 52,194 - 621 52,815   Total other investments 3,461 - - 3,461  Total investments $ 55,655 $ 592,645 $ 3,822 $ 652,122       As of December 31, 2017  Quoted Prices in Other  Active Markets for Observable Unobservable  Identical Assets Inputs Inputs  (Level 1) (Level 2) (Level 3) Total  U.S. Treasury securities and obligations of U.S. Government $ - $ 49,947 $ - $ 49,947  Corporate bonds - 278,760 313 279,073  Collateralized corporate bank loans - 125,937 - 125,937  Municipal bonds - 131,433 2,823 134,256  Mortgage-backed - 16,533 - 16,533  Total debt securities - 602,610 3,136 605,746   Total equity securities 51,142 - 621 51,763   Total other investments 3,824 - - 3,824  Total investments $ 54,966 $ 602,610 $ 3,757 $ 661,333  Due to significant unobservable inputs into the valuation model for certain municipal bonds, one corporate bond and one equity security as of March 31, 2018 and December 31, 2017, we classified these investments as Level 3 in the fair value hierarchy. We used an income approach in order to derive an estimated fair value of the municipal bonds classified as Level 3, which included inputs such as expected holding period, benchmark swap rate, benchmark discount rate and a discount rate premium for illiquidity. The corporate bond is a convertible senior note and its fair value was estimated by the sum of the bond value using an income approach discounting the scheduled interest and principal payments and the conversion feature utilizing a binomial lattice model. We also estimated the fair value of the corporate bond utilizing an as-if converted basis into the underlying securities. The equity security classified as Level 3 in the fair value hierarchy is an investment in a non-public entity. Given the size of this investment and since there was not an observable market for the security, we estimated its fair value as the fair value on the date we acquired the investment. Significant changes in the unobservable inputs in the fair value measurement of these municipal bonds could result in a significant change in the fair value measurement.  The following table summarizes the changes in fair value for all financial assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three months ended March 31, 2018 and 2017 (in thousands):     Beginning balance as of January 1, 2018 $ 3,757  Sales -  Settlements -  Purchases -  Issuances -  Total realized/unrealized gains included in net income 65  Net gains included in other comprehensive income -  Transfers into Level 3 -  Transfers out of Level 3 -  Ending balance as of March 31, 2018 $ 3,822    Beginning balance as of January 1, 2017 $ 5,945   Sales -  Settlements -  Purchases 775  Issuances -  Total realized/unrealized gains included in net income -  Net gains included in other comprehensive income 200  Transfers into Level 3 -  Transfers out of Level 3 -  Ending balance as of March 31, 2017 $ 6,920

At December 31, 2017, the gross unrealized losses more than twelve months old were attributable to 25 debt security positions. We consider these losses as a temporary decline in value as they are predominately on bonds that we do not intend to sell and do not believe we will be required to sell prior to recovery of our amortized cost basis. We see no other indications that the decline in values of these securities is other-than-temporary.  We complete a detailed analysis each quarter to assess whether any decline in the fair value of any fixed maturity investment below cost is deemed other-than-temporary. All fixed maturity investments with an unrealized loss are reviewed. We recognize an impairment loss when an investment's value declines below cost, adjusted for accretion, amortization and previous other-than-temporary impairments, and it is determined that the decline is other-than-temporary.  We assess whether we intend to sell, or it is more likely than not that we will be required to sell, a fixed maturity investment before recovery of its amortized cost basis less any current period credit losses. For fixed maturity investments that are considered other-than-temporarily impaired and that we do not intend to sell and will not be required to sell, we separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the investment’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the investment’s fair value and the present value of future expected cash flows is recognized in other comprehensive income. Details regarding the carrying value of the other investments portfolio as of March 31, 2018 and December 31, 2017 are as follows (in thousands):     March 31, December 31,  2018 2017  Investment Type  Equity warrant $ 3,461 $ 3,824  Total other investments $ 3,461 $ 3,824  We acquired this warrant in an active market.

Share-Based Payment Arrangements [Abstract]
Share-Based Payment Arrangements	7. Share-Based Payment Arrangements  Our 2005 Long Term Incentive Plan (“2005 LTIP”) is a stock compensation plan for key employees and non-employee directors that was initially approved by the shareholders on May 26, 2005 and expired by its terms on May 27, 2015. As of March 31, 2018, there were outstanding incentive stock options to purchase 127,574 shares of our common stock, non-qualified stock options to purchase 259,157 shares of our common stock. The exercise price of all such outstanding stock options is equal to the fair market value of our common stock on the date of grant.  Our 2015 Long Term Incentive Plan (“2015 LTIP”) was approved by shareholders on May 29, 2015. There are 2,000,000 shares authorized for issuance under the 2015 LTIP. As of March 31, 2018, restricted stock units representing the right to receive up to 324,440 shares of our common stock were outstanding under the 2015 LTIP. There were no stock option awards granted under the 2015 LTIP as of March 31, 2018.  Stock Options:  Incentive stock options granted under the 2005 LTIP prior to 2009 vest 10% , 20% , 30% and 40% on the first, second, third and fourth anniversary dates of the grant, respectively, and terminate five to ten years from the date of grant. Incentive stock options granted in 2009 vest in equal annual increments on each of the first seven anniversary dates and terminate ten years from the date of grant. One grant of 25,000 incentive stock options in 2010 vests in equal annual increments on each of the first three anniversary dates and terminates ten years from the date of grant. Non-qualified stock options granted under the 2005 LTIP generally vest 100% six months after the date of grant and terminate ten years from the date of grant. One grant of 200,000 non-qualified stock options in 2009 vests in equal annual increments on each of the first seven anniversary dates and terminates ten years from the date of grant.  A summary of the status of our stock options as of March 31, 2018 and changes during the three months then ended is presented below:      Average  Weighted Remaining Aggregate  Average Contractual Intrinsic  Number of Exercise Term Value  Shares Price (Years) ($000)   Outstanding at January 1, 2018 406,731 $ 7.85  Granted - $ -  Exercised - $ -  Forfeited or expired (20,000) $ 11.46  Outstanding at March 31, 2018 386,731 $ 7.66 1.0 $ 669  Exercisable at March 31, 2018 386,731 $ 7.66 1.0 $ 669            The following table details the intrinsic value of options exercised, total cost of share-based payments charged against income before income tax benefit and the amount of related income tax benefit recognized in income for the periods indicated (in thousands):      Three Months Ended  March 31,  2018 2017   Intrinsic value of options exercised $ - $ 21   Cost of share-based payments (non-cash) $ - $ -   Income tax benefit of share-based payments recognized in income $ - $ -  As of March 31, 2018, there was no unrecognized compensation cost related to non-vested stock options granted under our plans which is expected to be recognized in the future.  The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes option pricing model. Expected volatilities are based on the historical volatility of Hallmark’s and similar companies’ common stock for a period equal to the expected term. The risk-free interest rates for periods within the contractual term of the options are based on rates for U.S. Treasury Notes with maturity dates corresponding to the options expected lives on the dates of grant. Expected term is determined based on the simplified method as we do not have sufficient historical exercise data to provide a basis for estimating the expected term. There were no stock options granted during the first three months of 2018 or 2017.  Restricted Stock Units:  Restricted stock units awarded under the 2015 LTIP represent the right to receive shares of common stock upon the satisfaction of vesting requirements, performance criteria and other terms and conditions. Restricted stock units vest and, if performance criteria have been satisfied, shares of common stock become issuable on March 31 of the third calendar year following the year of grant.  The performance criteria for all restricted stock units require that we achieve certain compound average annual growth rates in book value per share as well as certain average combined ratio percentages over the vesting period in order to receive shares of common stock in amounts ranging from 50% to 150% of the number of restricted stock units granted. Grantees of restricted stock units do not have any rights of a stockholder, and do not participate in any distributions to our common stockholders, until the award fully vests upon satisfaction of the vesting schedule, performance criteria and other conditions set forth in their award agreement. Therefore, unvested restricted stock units are not considered participating securities under ASC 260, “Earnings Per Share,” and are not included in the calculation of basic or diluted earnings per share.  Compensation cost is measured as an amount equal to the fair value of the restricted stock units on the date of grant and is expensed over the vesting period if achievement of the performance criteria is deemed probable, with the amount of the expense recognized based on our best estimate of the ultimate achievement level. The grant date fair value of restricted stock units granted in 2015, 2016 and 2017 was $11.10 , $11.41 and $10.20 per unit, respectively. We incurred compensation expense of $44 thousand and $27 thousand related to restricted stock units during the three months ended March 31, 2018 and 2017, respectively. We recorded income tax benefit of $9 thousand related to restricted stock units during both the three months ended March 31, 2018 and 2017, respectively  A summary of the status of our restricted stock units as of March 31, 2018 and 2017 and changes during the three months then ended is presented below:     Number of  Restricted  Stock Units  2018 2017   Non-vested at January 1 385,779 296,574  Granted - -  Vested (8,198) (5,998)  Forfeited (161,288) (43,509)  Non-vested at March 31 216,293 247,067  As of March 31, 2018, there was $1.4 million of unrecognized grant date compensation cost related to unvested restricted stock units. Based on the current performance estimate, we expect to recognize $0.4 million of compensation cost related to unvested restricted stock units, of which $0.1 million is expected to be recognized during the remainder of 2018, $0.2 million is expected to be recognized in 2019 and $0.1 million is expected to be recognized in 2020.

Reinsurance [Abstract]
Reinsurance	9. Reinsurance  We reinsure a portion of the risk we underwrite in order to control the exposure to losses and to protect capital resources. We cede to reinsurers a portion of these risks and pay premiums based upon the risk and exposure of the policies subject to such reinsurance. Ceded reinsurance involves credit risk and is generally subject to aggregate loss limits. Although the reinsurer is liable to us to the extent of the reinsurance ceded, we are ultimately liable as the direct insurer on all risks reinsured. Reinsurance recoverables are reported after allowances for uncollectible amounts. We monitor the financial condition of reinsurers on an ongoing basis and review our reinsurance arrangements periodically. Reinsurers are selected based on their financial condition, business practices and the price of their product offerings. In order to mitigate credit risk to reinsurance companies, most of our reinsurance recoverable balance as of March 31, 2018 was with reinsurers that had an A.M. Best rating of “A–” or better.  The following table shows earned premiums ceded and reinsurance loss recoveries by period (in thousands):     Three Months Ended  March 31,  2018 2017   Ceded earned premiums $ 61,629 $ 45,717  Reinsurance recoveries $ 49,438 $ 26,701

Revolving Credit Facility [Abstract]
Revolving Credit Facility	10. Revolving Credit Facility  Our Second Restated Credit Agreement with Frost Bank (“Frost”) dated June 30, 2015, reinstated the credit facility with Frost which expired by its terms on April 30, 2015. The Second Restated Credit Agreement also amended certain provisions of the credit facility and restated the agreement with Frost in its entirety. The Second Restated Credit Agreement provides a $15.0 million revolving credit facility (“Facility A”), with a $5.0 million letter of credit sub-facility. The outstanding balance of the Facility A bears interest at a rate equal to the prime rate or LIBOR plus 2.5% , at our election. We pay an annual fee of 0.25% of the average daily unused balance of Facility A and letter of credit fees at the rate of 1.00% per annum. As of March 31, 2018, we had no outstanding borrowings under Facility A.  On December 17, 2015, we entered into a First Amendment to Second Restated Credit Agreement and a Revolving Facility B Agreement (the “Facility B Agreement”) with Frost to provide a new $30.0 million revolving credit facility (“Facility B”), in addition to Facility A. On November 1, 2016, we amended the Facility B Agreement with Frost to extend by one year the termination date for draws under Facility B and the maturity date for amounts outstanding thereunder. We paid Frost a commitment fee of $75,000 when Facility B was established and an additional $30,000 fee when Facility B was extended. On December 20, 2017, we entered into a Second Amendment to Second Restated Credit Agreement and a Second Amendment to Revolving Facility B Agreement with Frost. The Second Amendment to Second Restated Credit Agreement revised certain definitions in the Second Restated Credit Agreement. The Second Amendment to Revolving Facility B Agreement amended the Revolving Facility B Agreement to further extend by one year the termination date for draws thereunder and the maturity date for amounts outstanding thereunder. We paid Frost an additional $30,000 fee in connection with the latest extension of Facility B. On March 15, 2018, we entered into a Third Amendment to Second Restated Credit Agreement with Frost to further revise certain definitions.  We may use Facility B loan proceeds solely for the purpose of making capital contributions to AHIC and HIC. As amended, we may borrow, repay and reborrow under Facility B until December 17, 2019, at which time all amounts outstanding under Facility B are converted to a term loan. Through December 17, 2019, we pay Frost a quarterly fee of 0.25% per annum of the average daily unused balance of Facility B. Facility B bears interest at a rate equal to the prime rate or LIBOR plus 3.00% , at our election. Until December 17, 2019, interest only on amounts from time to time outstanding under Facility B are payable quarterly. Any amounts outstanding on Facility B as of December 17, 2019 are converted to a term loan payable in quarterly installments over five years based on a seven year amortization of principal plus accrued interest. All remaining principal and accrued interest on Facility B become due and payable on December 17, 2024. As of March 31, 2018, we had $30.0 million outstanding under Facility B.  The obligations under both Facility A and Facility B are secured by a security interest in the capital stock of AHIC and HIC. Both Facility A and Facility B contain covenants that, among other things, require us to maintain certain financial and operating ratios and restrict certain distributions, transactions and organizational changes. We are in compliance with or have obtained a waiver of all of these covenants.

Subordinated Debt Securities [Abstract]
Subordinated Debt Securities	11. Subordinated Debt Securities  On June 21, 2005, we entered into a trust preferred securities transaction pursuant to which we issued $30.9 million aggregate principal amount of subordinated debt securities due in 2035 . To effect the transaction, we formed Trust I as a Delaware statutory trust. Trust I issued $30.0 million of preferred securities to investors and $0.9 million of common securities to us. Trust I used the proceeds from these issuances to purchase the subordinated debt securities. The interest rate on our Trust I subordinated debt securities was 7.725 % until June 15, 2015 , after which interest adjusts quarterly to the three-month LIBOR rate plus 3.25 percentage points . Trust I pays dividends on its preferred securities at the same rate. Under the terms of our Trust I subordinated debt securities, we pay interest only each quarter and the principal of the note at maturity. The subordinated debt securities are uncollaterized and do not require maintenance of minimum financial covenants. As of March 31, 2018, the principal balance of our Trust I subordinated debt was $30.9 million and the interest rate was 5.37% per annum.  On August 23, 2007, we entered into a trust preferred securities transaction pursuant to which we issued $25.8 million aggregate principal amount of subordinated debt securities due in 2037 . To effect the transaction, we formed Trust II as a Delaware statutory trust. Trust II issued $25.0 million of preferred securities to investors and $0.8 million of common securities to us. Trust II used the proceeds from these issuances to purchase the subordinated debt securities. The interest rate on our Trust II subordinated debt securities was 8.28 % until September 15, 2017 , after which interest adjusts quarterly to the three-month LIBOR rate plus 2.90 percentage points. Trust II pays dividends on its preferred securities at the same rate. Under the terms of our Trust II subordinated debt securities, we pay interest only each quarter and the principal of the note at maturity. The subordinated debt securities are uncollaterized and do not require maintenance of minimum financial covenants. As of March 31, 2018, the principal balance of our Trust II subordinated debt was $25.8 million and the interest rate was 5.02% per annum.

Income Taxes [Abstract]
Income Taxes	15. Income Taxes  Our effective tax rate was 20% for the first quarter of 2018 as compared to 31.7% for the same period in 2017. The decrease in the effective tax rate was due primarily to the lower statutory rate from the enactment of the TCJA on December 22, 2017. The rates varied from the statutory rate primarily due to the amount of tax exempt income in relation to pretax income.

Basis of Presentation (Policy)

Basis of Presentation (Policy)	3 Months Ended

Basis of Presentation [Abstract]
Income Taxes	Income Taxes  We file a consolidated federal income tax return. Deferred federal income taxes reflect the future tax consequences of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end. Deferred taxes are recognized using the liability method, whereby tax rates are applied to cumulative temporary differences based on when and how they are expected to affect the tax return. Deferred tax assets and liabilities are adjusted for tax rate changes in effect for the year in which these temporary differences are expected to be recovered or settled. 
Use of Estimates in the Preparation of the Financial Statements	 Use of Estimates in the Preparation of the Financial Statements  Our preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect our reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting period. Refer to “Critical Accounting Estimates and Judgments” under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2017 for information on accounting policies that we consider critical in preparing our consolidated financial statements. Actual results could differ materially from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments  Fair value estimates are made at a point in time based on relevant market data as well as the best information available about the financial instruments. Fair value estimates for financial instruments for which no or limited observable market data is available are based on judgments regarding current economic conditions, credit and interest rate risk. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the instrument. In addition, changes in the underlying assumptions used in the fair value measurement technique, including discount rate and estimates of future cash flows, could significantly affect these fair value estimates.  Cash and Cash Equivalents : The carrying amounts reported in the balance sheet for these instruments approximate their fair values.  Restricted Cash : The carrying amount for restricted cash reported in the balance sheet approximates the fair value.  Revolving Credit Facility Payable : A revolving credit facility with Frost Bank had a carried value of $30.0 million and a fair value of $30.2 million as of March 31, 2018 . The fair value is based on discounted cash flows using a discount rate derived from LIBOR spot rates plus a market spread resulting in discount rates ranging between 4.4 % to 4.8 % for each future payment date. This revolving credit facility would be included in Level 3 of the fair value hierarchy if it was reported at fair value.  Subordinated Debt Securities : Our trust preferred securities have a carried value of $55.8 million and a fair value of $ 45.5 million as of March 31, 2018. The fair value of our trust preferred securities is based on discounted cash flows using a current yield to maturity of 8.0% , which is based on similar issues to discount future cash flows. Our trust preferred securities would be included in Level 3 of the fair value hierarchy if they were reported at fair value.  For reinsurance balances, premiums receivable, federal income tax recoverable, other assets and other liabilities, the carrying amounts approximate fair value because of the short maturity of such financial instruments.
Variable Interest Entities	Variable Interest Entities  On June 21, 2005, we formed Hallmark Statutory Trust I (“Trust I”), an unconsolidated trust subsidiary, for the sole purpose of issuing $30.0 million in trust preferred securities. Trust I used the proceeds from the sale of these securities and our initial capital contribution to purchase $30.9 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust I, and the payments under the debt securities are the sole revenues of Trust I.  On August 23, 2007, we formed Hallmark Statutory Trust II (“Trust II”), an unconsolidated trust subsidiary, for the sole purpose of issuing $25.0 million in trust preferred securities. Trust II used the proceeds from the sale of these securities and our initial capital contribution to purchase $25.8 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust II, and the payments under the debt securities are the sole revenues of Trust II.  We evaluate on an ongoing basis our investments in Trust I and Trust II (collectively the “Trusts”) and have determined that we do not have a variable interest in the Trusts. Therefore, the Trusts are not included in our consolidated financial statements.  We are also involved in the normal course of business with variable interest entities (“VIE’s”) primarily as a passive investor in mortgage-backed securities and certain collateralized corporate bank loans issued by third party VIE’s. The maximum exposure to loss with respect to these investments is the investment carrying values included in the consolidated balance sheets. 
New Accounting Pronouncements	 In January 2017, the FASB issued ASU 2017-01, “Clarifying the Definition of a Business” (Topic 715). ASU 2017-01 is intended to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  On February 14, 2018, the FASB issued updated guidance that allows a reclassification of the stranded tax effects in accumulated other comprehensive income (AOCI) resulting from the Tax Cuts and Jobs Act of 2017 (TCJA). Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of TCJA related to items in AOCI. The updated guidance was effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the TCJA related to items remaining in AOCI are recognized or at the beginning of the period of adoption. Early adoption is permitted. The Company adopted the updated guidance effective January 1, 2018 and elected to reclassify the income tax effects of the TCJA from AOCI to retained earnings as of January 1, 2018. This reclassification resulted in a decrease in retained earnings of $2.6 million as of January 1, 2018 and an increase in AOCI by the same amount.  In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (Subtopic 825-10). ASU 2016-01 will require equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. ASU 2016-01 will also require us to assess the ability to realize our deferred tax assets (“DTAs”) related to an available-for-sale debt security in combination with our other DTAs. ASU 2016-01 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this guidance resulted in the recognition of $17.0 million of net after-tax unrealized gains on equity investments as a cumulative effect adjustment that increased retained earnings as of January 1, 2018 and decreased AOCI by the same amount. The Company elected to report changes in the fair value of equity investments in investment gains and (losses) in the Consolidated Statement of Operations. At December 31, 2017, equity investments were classified as available-for-sale on the Company's balance sheet. However, upon adoption, the updated guidance eliminated the available-for-sale balance sheet classification for equity investments .  In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (Topic 230). ASU 2016-15 will reduce diversity in practice on how eight specific cash receipts and payments are classified on the statement of cash flows. The ASU will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The purpose of ASU 2016-18 is to eliminate the diversity in classifying and presenting changes in restricted cash in the statement of cash flows. The new guidance requires restricted cash to be combined with cash and cash equivalents when reconciling the beginning and ending balances of cash on the statement of cash flows, thereby no longer requiring transactions such as transfers between restricted and unrestricted cash to be treated as a cash flow activity. Further, the new guidance requires the nature of the restrictions to be disclosed, as well as a reconciliation between the balance sheet and the statement of cash flows on how restricted and unrestricted cash are segregated. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within that fiscal year, with early adoption permitted. Effective January 1, 2018, we retrospectively adopted this new guidance.  In May 2014, the FASB issued guidance which revises the criteria for revenue recognition. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies the performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs. The guidance was effective for reporting periods beginning after December 15, 2017 and is to be applied retrospectively. Revenue from insurance contracts is excluded from the scope of this new guidance. While insurance contracts are excluded from this guidance, policy fee income, billing and other fees and fee income related to property business written as a cover-holder through a Lloyds Syndicate will be subject to this updated guidance. Effective January 1, 2018, we adopted this new guidance which did not have a material impact on our financial results or disclosures.  Recently Issued Accounting Pronouncements  In March 2017, the FASB issued ASU 2017-08, “Premium Amortization on Purchased Callable Securities” (Subtopic 310-20). ASU 2017-08 is intended to enhance the accounting for amortization of premiums for purchased callable debt securities. The guidance amends the amortization period for certain purchased callable debt securities held at a premium. Securities that contain explicit, noncontingent call features that are callable at fixed prices and on preset dates should shorten the amortization period for the premium to the earliest call date (and if the call option is not exercised, the effective yield is reset using the payment terms of the debt security). The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings. We are currently evaluating the impact that the adoption of ASU 2017-08 will have on our financial results and disclosures. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (Topic 350). ASU 2017-04 requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We are currently evaluating the impact that the adoption of ASU 2017-04 will have on our financial results and disclosures.  In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016-13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. ASU 2016-13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures, but do not anticipate that any potential impact would be material.  In February 2016, the FASB issued ASU 2016-02, “Leases” (Topic 842). ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, ASU 2016-02 modifies current guidance for lessors' accounting. ASU 2016-02 is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. We do not anticipate that this standard will have a material impact on our results of operations, but we anticipate an increase to the value of our assets and liabilities related to leases, with no material impact to equity.
