Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Condensed Consolidated Financial Statements	Basis of Condensed Consolidated Financial Statements CoreLogic, Inc., together with its subsidiaries (collectively "we", "us" or "our"), is a leading global property information, insight, analytics and data-enabled solutions provider operating in North America, Western Europe and Asia Pacific. Our combined data from public, contributory and proprietary sources provides detailed coverage of property, mortgages and other encumbrances, consumer credit, tenancy, location, hazard risk and related performance information. The markets we serve include real estate and mortgage finance, insurance, capital markets and the public sector. We deliver value to clients through unique data, analytics, workflow technology, advisory and managed solutions. Clients rely on us to help identify and manage growth opportunities, improve performance and mitigate risk. Our condensed consolidated financial information included in this report has been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the condensed consolidated financial statements and accompanying notes. Actual amounts may differ from these estimated amounts. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The 2016 year-end condensed consolidated balance sheet was derived from the Company's audited financial statements for the year ended December 31, 2016 . Interim financial information does not require the inclusion of all the information and footnotes required by GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2016 . The accompanying unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of only normal recurring items which, in the opinion of management, are necessary for a fair statement of the results of operations for the periods shown. The results of operations for such periods are not necessarily indicative of the results expected for the full year or for any future periods. Client Concentration We generate the majority of our revenues from clients with operations in the U.S. residential real estate, mortgage origination and mortgage servicing markets. Approximately 37% and 41% of our operating revenues for the three months ended September 30, 2017 and 2016 , respectively, and 39% and 42% for the nine months ended September 30, 2017 and 2016 , respectively, were generated from our top ten clients, who consist of the largest U.S. mortgage originators and servicers. One of our clients accounted for approximately 11% of our operating revenues for the three months ended September 30, 2017 , and two of our customers accounted for approximately 15% and 11% of our operating revenues for the three months ended September 30, 2016 . Two of our clients accounted for approximately 12% and 10% of our operating revenues for the nine months ended September 30, 2017 and 15% and 12% of our operating revenues for the nine months ended September 30, 2016 . Out-of-Period Correction During the second quarter of 2017, we identified a balance sheet misclassification related to certain liability balances, which overstated our accounts payable and accrued expenses and understated other liabilities by approximately $32.0 million as of December 31, 2016. We corrected the balance sheet misclassification error on a prospective basis during the second quarter of 2017 as we determined the misclassification error was not material to the current financial condition or for the prior annual or interim periods. During 2017, we identified errors which had previously overstated our provision for income taxes by $4.3 million reflected within net income from continuing operations for the year ended December 31, 2015. As a result, we recorded out-of-period adjustments of $1.3 million and $3.0 million in the three months ended June 30, 2017 and September 30, 2017, respectively, lowering our provision for incomes taxes in both periods. We assessed the materiality of the aggregated errors and concluded that the errors were not material to the results of operations or financial condition for the current or prior annual and interim periods, and the corrections are not expected to be material to the full year results for fiscal year 2017. Comprehensive Income Comprehensive income includes all changes in equity except those resulting from investments by owners and distributions to owners. Specifically, foreign currency translation adjustments, amounts related to supplemental benefit plans, unrealized gains and losses on interest rate swap transactions and unrealized gains and losses on investment are recorded in other comprehensive income/(loss). The following table shows the components of accumulated other comprehensive loss, net of taxes as of September 30, 2017 and December 31, 2016 : 2017 2016 Cumulative foreign currency translation $ (95,310 ) $ (118,071 ) Cumulative supplemental benefit plans (4,748 ) (6,267 ) Net unrecognized gains on interest rate swaps 3,541 1,920 Accumulated other comprehensive loss $ (96,517 ) $ (122,418 ) Investment in Affiliates Investments in affiliates are accounted for under the equity method of accounting when we are deemed to have significant influence over the affiliate but do not control or have a majority voting interest in the affiliate. Investments are carried at the cost of acquisition, including subsequent impairments, capital contributions and loans from us, plus our equity in undistributed earnings or losses since inception of the investment. We recorded equity in losses of affiliates, net of tax of $0.2 million and equity in earnings of affiliates, net of tax of $0.6 million for the three months ended September 30, 2017 and 2016 , respectively, and equity in losses of affiliates, net of tax of $1.2 million and equity in earnings of affiliates, net of tax of $0.6 million for the nine months ended September 30, 2017 and 2016 , respectively. For the three months ended September 30, 2017 and 2016 , we recorded $2.8 million and $2.5 million , respectively, of operating revenues and $3.2 million and $2.9 million , respectively, of operating expenses related to our investment in affiliates. For the nine months ended September 30, 2017 and 2016 , we recorded $6.9 million and $7.7 million , respectively, of operating revenues and $8.9 million and $8.4 million , respectively, of operating expenses related to our investment in affiliates. In June 2017, we acquired a 45.0% interest in Mercury Network, LLC ("Mercury") for $70.0 million , which included a call option to purchase the remaining 55.0% interest within the next nine-month period. We fair-valued the call option using the Black-Scholes model at $4.6 million . In August 2017, we purchased the remaining 55.0% ownership of Mercury for an additional $83.0 million and wrote-off our related call option, which resulted in a net loss of $1.9 million within loss on extinguishment of debt and other, net, in the accompanying consolidated statement of operations for the three months ended September 30, 2017 . See Note 8 - Fair Value of Financial Instruments for further discussion. Prior to our acquisition of the controlling interest, we accounted for the investment in Mercury using the equity method. As of August 2017 we completed the acquisition, see Note 11 - Acquisitions for further discussion. Tax Escrow Disbursement Arrangements We administer tax escrow disbursements as a service to our clients in connection with our property tax processing solutions. These deposits are maintained in segregated accounts for the benefit of our clients. Tax escrow deposits totaled $1.3 billion as of September 30, 2017 and $619.4 million as of December 31, 2016 . Because these deposits are held on behalf of our clients, they are not our funds and, therefore, are not included in the accompanying condensed consolidated balance sheets. These deposits generally remain in the accounts for a period of two to five business days. We earn interest income or earnings credits from these deposits and bear the cost of bank-related fees. Under our contracts with our clients, if we make a payment in error or fail to pay a taxing authority when a payment is due, we could be held liable to our clients for all or part of the financial loss they suffer as a result of our act or omission. We maintained claim reserves relating to incorrect disposition of assets of $21.2 million and $22.2 million as of September 30, 2017 and December 31, 2016 , respectively, which is reflected in our accompanying condensed consolidated balance sheets as a component of other liabilities. Pension Plan Buyout We have historically offered a variety of employee benefit plans, including a defined benefit pension plan incorporated with the acquisition of RELS (the "RELS Pension Plan"). The RELS Pension Plan offered participants lump sum and annuity payment options based on a number of factors. In October 2016, RELS voted to terminate the RELS Pension Plan effective October 31, 2016. In June 2017, we made a contribution of $13.5 million to settle the defined benefit pension plan incorporated with the acquisition of RELS. We recorded a loss of $6.1 million within loss on extinguishment of debt and other, net in our condensed consolidated statement of operations and cleared the corresponding RELS Pension Plan liability of $9.2 million and corresponding accumulated other comprehensive loss of $1.8 million within our condensed consolidated balance sheets and condensed consolidated statements of comprehensive income. Recent Accounting Pronouncements In August 2017, Financial Accounting Standards Board (“FASB”) issued guidance to amend and improve the accounting for hedging activities. The amendment eliminates the requirement to separately measure and report hedge ineffectiveness. An initial quantitative assessment to establish that the hedge is highly effective is still required but the amendment allows until the end of the first quarter it is designated to perform to prepare the assessment. After initial qualification, a qualitative assessment can be performed if the hedge is highly effective and the documentation at inception can reasonably support an expectation of high effectiveness throughout the hedge’s term. The amendment requires companies to present all hedged accounting elements that affect earnings in the same income statement line as the hedged item. For highly effective cash flow hedges, fair value changes will be recorded in other comprehensive income and reclassed to earnings when the hedged item impacts earnings. The guidance is effective prospectively in fiscal years beginning after December 15, 2018. Early adoption is permitted but we do not anticipate to elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In May 2014, the FASB issued updated guidance on revenue recognition in order to i) remove inconsistencies in revenue requirements, ii) provide a better framework for addressing revenue issues, iii) improve comparability across entities, industries, jurisdictions, and capital markets, iv) provide more useful information through improved disclosures, and v) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. Under the amendment, an entity should recognize revenue to depict the transfer of promised goods or services to clients in the amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting treatment for the incremental costs of obtaining a contract, which would not have been incurred had the contract not been obtained. Further, an entity is required to disclose sufficient information to enable the user of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows from contracts with clients. The updated guidance provides two methods of adoption: i) retrospective application to each prior reporting period presented, or ii) recognition of the cumulative effect from the retrospective application at the date of initial application. We elected the modified retrospective approach. As updated by FASB in August 2015, the guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Earlier adoption was permitted for annual reporting periods beginning after December 15, 2016 but we did not elect early adoption. Accordingly, we will adopt the new standard as of January 1, 2018. In adopting the updated guidance, we are implementing changes to our accounting policies, business and contract-management processes. We anticipate that our notes to the consolidated financial statements related to revenue recognition will be expanded and the most substantial change to our consolidated financial statements will be a net increase to total deferred revenue of approximately 5% , primarily within our Risk Management and Work Flow (“RMW”) reporting segment, in the initial year of adoption. The expected increase to deferred revenue is principally driven by a change in the accounting for contracts with future discounts that give rise to material rights. Under the current standard, these future discounts are recognized at a point-in-time whereas, under the updated guidance, a portion of the consideration is allocated to material rights and recognized when the future goods or services are transferred. The cumulative impact of all changes to stockholders’ equity is expected to be a net reduction of approximately 5% upon implementation. Further, the updated guidance is not expected to materially impact our revenues and results of operations in the upcoming fiscal years and interim periods. However, we are still in the process of updating our systems and financial controls and continue to review the presentation of our consolidated financial statements and related disclosures required by the updated guidance.

Credit Agreement In August 2017, we amended and restated our credit agreement (the “Credit Agreement”) with Bank of America, N.A. as the administrative agent, and other financial institutions. The Credit Agreement provides for a $1.8 billion five-year term A loan facility (the “Term Facility”), and a $700.0 million five-year revolving credit facility ("Revolving Facility"). The Term Facility matures and the Revolving Facility expires in August 2022. The Revolving facility includes a $100.0 million multicurrency revolving sub-facility and a $50.0 million letter of credit sub-facility. The Credit Agreement also provides for the ability to increase the Term Facility and/or Revolving Facility by up to $100.0 million in the aggregate; however the lenders are not obligated to do so. The loans under the Credit Agreement will bear interest, at the election of the Company, at (i) the Alternate Base Rate (defined as the greatest of (a) Bank of America's “prime rate”, (b) the Federal Funds effective rate plus 0.50% and (c) the reserve adjusted London interbank offering rate for a one month Eurocurrency borrowing plus 1.00% ) plus the Applicable Rate (as defined in the Credit Agreement) or (ii) the London interbank offering rate for Eurocurrency borrowings, adjusted for statutory reserves (the “Adjusted Eurocurrency Rate”) plus the Applicable Rate. The initial Applicable Rate for Alternate Base Rate borrowings is 1.00% and for Adjusted Eurocurrency Rate borrowings is 2.00% . After December 31, 2017, the Applicable Rate will vary depending upon the Company's leverage ratio. The minimum Applicable Rate for Alternate Base Rate borrowings will be 0.25% and the maximum will be 1.00% . The minimum Applicable Rate for Adjusted Eurocurrency Rate borrowings will be 1.25% and the maximum will be 2.00% . The Credit Agreement also requires the Company to pay a commitment fee for the unused portion of the Revolving Facility, which will be a minimum of 0.25% and a maximum of 0.40% , depending on the Company's leverage ratio. The Credit Agreement provides that loans under the Term Facility shall be repaid in equal quarterly installments, commencing on the last day of the next full fiscal quarter and continuing on each three-month anniversary thereafter. The loans under the Term Facility shall be repaid in an amount equal to $22.5 million for the first eight quarterly payments and in an amount equal to $45.0 million for each quarterly payment thereafter. The outstanding balance of the term loans will be due in August 2022. The Credit Agreement contains the following financial maintenance covenants: (i) a maximum total leverage ratio not to exceed 4.50 : 1.00 ; (stepped down to 4.25 : 1.00 starting with the fiscal quarter ending on September 30, 2018, with a further step down to 4.00 : 1.00 starting with the fiscal quarter ending on September 30, 2019, with an additional step down to 3.75 : 1.00 starting with the fiscal quarter ending on September 30, 2020, and a final step down to 3.50 to 1.00 starting with the fiscal quarter ending on September 30, 2021) and (ii) a minimum interest coverage ratio of at least 3.50 : 1.00 . At September 30, 2017, we had borrowing capacity of $700.0 million under the Revolving Facility and we were in compliance with all of our covenants under the Credit Agreement. Debt Issuance Costs In connection with the amendment and restatement of the Credit Agreement, we incurred approximately $14.3 million of debt issuance costs of which $0.3 million were expensed in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2017. We capitalized the remaining $14.0 million of debt issuance costs within long-term debt, net in the accompanying condensed consolidated balance sheets, and will amortize these costs over the term of the Credit Agreement. When we amended and restated the Credit Agreement, we had unamortized costs of $13.8 million , of which we wrote-off $1.8 million for the year ended September 30, 2017 and the remaining $12.0 million will amortize over the term of the Credit Agreement. For the nine months ended September 30, 2016, we recorded $6.3 million of debt issuance costs of which $0.3 million were expensed in the accompanying condensed consolidated statements of operations. We capitalized the remaining $6.0 million of debt issuance costs within long-term debt, net in the accompanying condensed consolidated balance sheets. Further, we wrote-off $10.2 million of unamortized debt issuance costs during the nine months ended September 30, 2016. 7.55% Senior Debentures In April 1998, we issued $100.0 million in aggregate principal amount of 7.55% senior debentures due 2028. The indentures governing these debentures, as amended, contain limited restrictions on the Company. Interest Rate Swaps We have entered into amortizing interest rate swaps ("Swaps") in order to convert a portion of our interest rate exposure on the Term Facility floating rate borrowings from variable to fixed. In June 2017, we entered into Swaps which become effective in March 2018 and terminate in March 2021. The Swaps entered in June 2017 are for an initial notional balance of $275.0 million , with a notional step up of $200.0 million in March 2019 and a fixed interest rate of 1.83% . In August 2016, we entered into Swaps which became effective in September 2016 and terminate in April 2020. The Swaps entered in August 2016 are for an initial notional balance of $500.0 million , with a fixed interest rate of 1.03% , and amortize quarterly by $25.0 million through December 2018, with a notional step up of $100.0 million in March 2019, continued quarterly amortization of $25.0 million through April 2020, and a remaining notional amount of $275.0 million . In May 2014, we entered into Swaps which became effective in December 2014 and terminate in March 2019. The Swaps entered in May 2014 are for an initial notional balance of $500.0 million , with a fixed interest rate of 1.57% , and amortize quarterly by $12.5 million through December 31, 2017 and $25.0 million through December 31, 2018. We have designated the Swaps as cash flow hedges. The estimated fair value of these cash flow hedges is recorded in other assets and/or other liabilities in the accompanying condensed consolidated balance sheets. The estimated fair value of these cash flow hedges resulted in an asset of $6.0 million and a liability of $0.2 million as of September 30, 2017 . We recorded an asset of $5.4 million and a liability of $2.3 million as of December 31, 2016 . Unrealized gains of less than $0.1 million (net of less than $0.1 million in deferred taxes) and unrealized gains of $0.4 million (net of $0.2 million in deferred taxes) for the three months ended September 30, 2017 and 2016 , respectively, and unrealized gains of $1.6 million (net of $1.0 million in deferred taxes) and unrealized losses of $2.7 million (net of $1.7 million in deferred taxes) for the nine months ended September 30, 2017 and 2016 , respectively, were recognized in other comprehensive income/(loss) related to the Swaps.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate for income taxes as a percentage of income from continuing operations before equity in losses of affiliates and income taxes was 27.6% and 31.0% for the three months ended September 30, 2017 and 2016 , respectively, and 30.0% and 33.5% for the nine months ended September 30, 2017 and 2016 , respectively. For the three months ended September 30, 2017 , when compared to 2016 , the decrease in the effective income tax rate was primarily attributable to a favorable domestic out-of-period adjustment recorded in the third quarter of 2017 and favorable discrete items, partially offset by unfavorable foreign rate differentials, due to foreign exchange gain and losses in jurisdictions with tax rates lower than the U.S., and a nonrecurring prior year favorable adjustment related to contingent consideration recorded in connection with an acquisition. For the nine months ended September 30, 2017 when compared to 2016 , the decrease in the effective tax rate was primarily attributable to a favorable domestic out-of-period adjustment recorded in the third quarter of 2017 and favorable discrete items and favorable tax benefits related to the adoption of stock-based compensation accounting guidance, partially offset by unfavorable foreign rate differentials, due to foreign exchange gain and losses in jurisdictions with tax rates lower than the U.S., and a nonrecurring prior year favorable release of reserves for foreign uncertain tax benefits. Income taxes included in equity in losses of affiliates were a benefit of $0.1 million and expense of $0.5 million for the three months ended September 30, 2017 and 2016 , respectively, and a benefit of $0.8 million and expense of $0.9 million for the nine months ended September 30, 2017 and 2016 , respectively. For the purpose of segment reporting, these amounts are included in corporate and therefore not reflected in our reportable segments. We are currently under examination for the years 2006-2011, by the US, our primary taxing jurisdiction, and various other state taxing authorities. It is reasonably possible the amount of the unrecognized benefits with respect to unrecognized tax positions could change within the next twelve months. The portion of uncertain tax benefits that are not subject to the First American Financial Corporation (“FAFC”) indemnification could significantly increase or decrease and have an impact on net income. The FAFC indemnification could change by up to $14.0 million due to statutory requirements and would have no impact on net income.

For the nine months ended September 30, 2017 and 2016 , an aggregate of less than 0.1 million RSUs and an aggregate of less than 0.1 million stock options, respectively, were excluded from the weighted-average diluted common shares outstanding due to their anti-dilutive effect.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The market approach is applied for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value balances are classified based on the observability of those inputs. A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize observable inputs in active markets for similar assets and liabilities, or, quoted prices in markets that are not active. In estimating the fair value of the financial instruments presented, we used the following methods and assumptions: Cash and cash equivalents For cash and cash equivalents, the carrying value is a reasonable estimate of fair value due to the short-term nature of the instruments. Restricted cash Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit secured by us and escrow accounts due to acquisitions and divestitures. We deem the carrying value to be a reasonable estimate of fair value due to the nature of these instruments. Contingent consideration The fair value of the contingent consideration was estimated using the Monte-Carlo simulation model, which relies on significant assumption and estimates including discount rates and future market conditions, among others. Long-term debt The fair value of debt was estimated based on the current rates available to us for similar debt of the same remaining maturities and consideration of our default and credit risk. Swaps The fair value of the interest rate swap agreements were estimated based on market-value quotes received from the counterparties to the agreements. The fair values of our financial instruments as of September 30, 2017 are presented in the following table: Fair Value Measurements Using (in thousands) Level 1 Level 2 Level 3 Fair Value Financial Assets: Cash and cash equivalents $ 149,411 $ — $ — $ 149,411 Restricted cash — 13,532 — 13,532 Total Financial Assets $ 149,411 $ 13,532 $ — $ 162,943 Financial Liabilities: Contingent consideration $ — $ — $ 1,800 $ 1,800 Total debt — 1,825,984 — 1,825,984 Total Financial Liabilities $ — $ 1,825,984 $ 1,800 $ 1,827,784 Swaps: Asset for swap $ — $ 5,951 $ — $ 5,951 Liability for swap $ — $ 217 $ — $ 217 The fair values of our financial instruments as of December 31, 2016 are presented in the following table: Fair Value Measurements Using (in thousands) Level 1 Level 2 Level 3 Fair Value Financial Assets: Cash and cash equivalents $ 72,031 $ — $ — $ 72,031 Restricted cash — 17,943 — 17,943 Total Financial Assets $ 72,031 $ 17,943 $ — $ 89,974 Financial Liabilities: Total debt $ — $ 1,622,811 $ — $ 1,622,811 Swaps: Asset for swap $ — $ 5,392 $ — $ 5,392 Liability for swap $ — $ 2,283 $ — $ 2,283 There were no transfers between Level 1, Level 2 or Level 3 securities during the three and nine months ended September 30, 2017 . In connection with our call option related to the Mercury acquisition, we recorded a loss of $4.6 million in our condensed consolidated statement of operations for both the three and nine months ended September 30, 2017. See Note 11 - Acquisitions for further discussion. In connection with our acquisition of Myriad in August 2017, we entered into a contingent consideration agreement of up to $3.0 million to be paid in cash in 2019 upon the achievement of certain revenue targets in fiscal years 2017 and 2018. See Note 11 - Acquisition for further discussion. We fair valued the contingent payment using the Monte-Carlo simulation model and initially recorded $1.8 million as contingent consideration. The contingent payment is fair-valued quarterly and changes are recorded within loss on extinguishment of debt and other, net in our condensed consolidated statement of operations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation We currently issue equity awards under the Amended and Restated CoreLogic, Inc. 2011 Performance Incentive Plan, which was initially approved by our stockholders at our Annual Meeting held on May 19, 2011 with an amendment and restatement approved by our stockholders at our Annual Meeting held on July 29, 2014, and a subsequent technical amendment by the Board in December 2016 (the “Plan”). The Plan includes the ability to grant RSUs, performance-based restricted stock units ("PBRSUs") and stock options. Prior to the approval of the Plan, we issued share-based awards under the CoreLogic, Inc. 2006 Incentive Plan. The Plan provides for up to 21,909,000 shares of the Company's common stock to be available for award grants. We primarily utilize RSUs and PBRSUs as our share-based compensation instruments for employees and directors. The fair value of any share-based compensation instrument grant is based on the market value of our shares on the date of grant and is recognized as compensation expense over its vesting period. Restricted Stock Units For the nine months ended September 30, 2017 and 2016 , we awarded 671,568 and 967,826 RSUs, respectively, with an estimated grant-date fair value of $26.9 million and $33.7 million , respectively. The RSU awards will vest ratably over three years from their grant date. RSU activity for the nine months ended September 30, 2017 is as follows: Number of Weighted-Average Grant-Date (in thousands, except weighted-average fair value prices) Shares Fair Value Unvested RSUs outstanding at December 31, 2016 1,555 $ 34.14 RSUs granted 672 $ 39.99 RSUs vested (858 ) $ 34.29 RSUs forfeited (61 ) $ 35.87 Unvested RSUs outstanding at September 30, 2017 1,308 $ 37.22 As of September 30, 2017 , there was $31.8 million of total unrecognized compensation cost related to unvested RSUs that is expected to be recognized over a weighted-average period of 2.0 years . The fair value of RSUs is based on the market value of our common stock on the date of grant. Performance-Based Restricted Stock Units For the nine months ended September 30, 2017 and 2016 , we awarded 288,331 and 285,475 PBRSUs, respectively, with an estimated grant-date fair value of $11.5 million and $10.1 million , respectively. These awards are subject to service-based, performance-based and market-based vesting conditions. For PBRSUs awarded during the nine months ended September 30, 2017 , the performance period is from January 1, 2017 to December 31, 2019 and the performance metrics are adjusted earnings per share and market-based conditions. Subject to satisfaction of the performance criteria, the 2017 awards will vest on December 31, 2019. The performance period for the PBRSUs awarded during the nine months ended September 30, 2016 is from January 1, 2016 to December 31, 2018 and the performance metrics are adjusted earnings per share and market-based conditions. Subject to satisfaction of the performance criteria, the 2016 awards will vest on December 31, 2018. The fair values of the 2017 and 2016 awards were estimated using Monte-Carlo simulation with the following weighted-average assumptions: For the Nine Months Ended September 30, 2017 2016 Expected dividend yield — % — % Risk-free interest rate (1) 1.47 % 0.99 % Expected volatility (2) 27.83 % 25.12 % Average total stockholder return (2) 1.46 % (1.23 )% (1) The risk-free interest rate for the periods within the contractual term of the PBRSUs is based on the U.S. Treasury yield curve in effect at the time of the grant. (2) The expected volatility and average total stockholder return are measures of the amount by which a stock price has fluctuated or is expected to fluctuate based primarily on our and our peers' historical data. PBRSU activity for the nine months ended September 30, 2017 is as follows: Number of Weighted-Average Grant-Date (in thousands, except weighted-average fair value prices) Shares Fair Value Unvested PBRSUs outstanding at December 31, 2016 738 $ 34.13 PBRSUs granted 288 $ 39.79 PBRSUs vested (227 ) $ 31.90 PBRSUs forfeited (159 ) $ 36.48 Unvested PBRSUs outstanding at September 30, 2017 640 $ 36.91 As of September 30, 2017 , there was $10.3 million of total unrecog n ized compensation cost related to unvested PBRSUs that is expected to be recognized over a weighted-average period of 1.8 years. The fair value of PBRSUs is based on the market value of our common stock on the date of grant. Stock Options Prior to 2015, we issued stock options as incentive compensation for certain employees. Option activity for the nine months ended September 30, 2017 is as follows: (in thousands, except weighted-average price) Number of Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term Aggregate Intrinsic Value Options outstanding at December 31, 2016 1,504 $ 21.22 Options exercised (215 ) $ 24.69 Options vested, exercisable, and outstanding at September 30, 2017 1,289 $ 20.64 2.4 $ 32,985 As of September 30, 2017 , there was no unrecognized compensation cost related to unvested stock options. The intrinsic value of options exercised was $3.3 million and $4.4 million for the nine months ended September 30, 2017 and 2016 , respectively. This intrinsic value represents the difference between the fair market value of our common stock on the date of exercise and the exercise price of each option. Employee Stock Purchase Plan The employee stock purchase plan allows eligible employees to purchase our common stock at 85.0% of the lesser of the closing price on the first day or the last day of each quarter. Our employee stock purchase plan was approved by our stockholders at our 2012 annual meeting of stockholders and the first offering period commenced in October 2012.

Litigation and Regulatory Conti

Litigation and Regulatory Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Litigation and Regulatory Contingencies	Litigation and Regulatory Contingencies We have been named in various lawsuits and we may from time to time be subject to audit or investigation by governmental agencies. Currently, governmental agencies are auditing or investigating certain of our operations. With respect to matters where we have determined that a loss is both probable and reasonably estimable, we have recorded a liability representing our best estimate of the financial exposure based on known facts. For matters where a settlement has been reached, we have recorded the expected amount(s) of such settlements. With respect to audits, investigations or lawsuits that are ongoing, although their final dispositions are not yet determinable, we do not believe that the ultimate resolution of such matters, either individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows. As of September 30, 2017, we do not believe that a material loss exceeding amounts accrued of $20.1 million is probable, of which $17.6 million was recorded in the three months ended September 30, 2017 . The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. We record expenses for legal fees as incurred. Fair Credit Reporting Act Class Actions In February 2012, CoreLogic National Background Data, LLC (n/k/a CoreLogic Background Data, LLC) (“CBD”) was named as a defendant in a putative class action styled Tyrone Henderson, et. al., v. CoreLogic National Background Data, in the United States District Court for the Eastern District of Virginia. Plaintiffs allege violation of the Fair Credit Reporting Act, and have pled a putative class claim relating to CBD’s return of criminal record data in response to search queries initiated by its consumer reporting agency customers, which then prepare and transmit employment background screening reports to their employer customers. Plaintiffs contend that CBD failed to send notice letters to consumers each time search results were returned to CBD’s consumer reporting agency customers. In February 2016, the court denied CBD’s motion for partial summary judgment. Plaintiffs initially sought to represent a nationwide class of consumers who were the subject of searches conducted by CBD’s customers. The court denied without prejudice Plaintiffs’ motion to certify a nationwide class on three separate occasions in April 2015, April 2016 and September 2016. However, in September 2016, the court allowed Plaintiffs to seek certification of three subclasses and in March 2017, Plaintiffs filed a motion for class certification as to one of these subclasses, seeking to certify a class of consumers for whom sex offender records were returned that did not reflect a date of birth associated with the record. Following a series of judicial settlement conferences concluding in August 2017, the parties entered into an agreement to settle the case with respect to a class of 75,400 consumers. In September 2017, the court preliminarily approved the settlement. A final fairness hearing is set for January 2018. In June 2015, a companion case, Witt v. CoreLogic National Background Data, et. al. was filed in the United States District Court for the Eastern District of Virginia by the same attorneys as in Henderson, alleging the same claim against CBD. Witt also names as a defendant CoreLogic SafeRent, LLC (n/k/a CoreLogic Rental Property Solutions, LLC (“RPS”)) on the theory that RPS provides criminal record “reports” to CBD at the same time that CBD delivers reports to CBD’s consumer reporting agency customers. Witt is pending in the same court and before the same judge as Henderson, and the two cases have been deemed related by the Court. In April 2017, Plaintiffs filed a motion for class certification, seeking to certify a class of consumers for whom Virginia criminal record data was returned that did not reflect a year of birth associated with the record. Following a series of judicial settlement conferences concluding in August 2017, the parties entered into two agreements to settle the case with respect to two classes, which together total 216,226 consumers. In September 2017, the court preliminarily approved the settlements. A final fairness hearing is set for January 2018. On July 2017, CoreLogic SafeRent, LLC (n/k/a CoreLogic Rental Property Solutions, LLC (“RPS”)) was named as a defendant in a putative class action lawsuit styled Claudinne Feliciano, et. al., v. CoreLogic SafeRent, LLC, in the United States District Court for the Southern District of New York. An amended complaint was filed on August 9 to name RPS as the Defendant, and service was made on August 11. The case alleges violation of the Fair Credit Reporting Act and the New York Fair Credit Reporting Act. The named plaintiff alleges that RPS prepared a background screening report about her that contained a record of a New York Housing Court action without noting that the action had previously been dismissed. Plaintiff seeks to represent a class of similarly situated consumers with respect to reports issued during the period of July 2015 to the present. RPS filed an answer on October 2017, denying liability. RPS intends to defend against these claims vigorously. Separation Following the Separation, we are responsible for a portion of FAFC's contingent and other corporate liabilities. In the Separation and Distribution Agreement we entered into in connection with the Separation (the "Separation and Distribution Agreement"), we agreed with FAFC to share equally in the cost of resolution of a small number of corporate-level lawsuits, including certain consolidated securities litigation matters from which we have since been dropped. There were no liabilities incurred in connection with the consolidated securities matters. Responsibility to manage each case has been assigned to either FAFC or us, with the managing party required to update the other party regularly and consult with the other party prior to certain important decisions, such as settlement. The managing party will also have primary responsibility for determining the ultimate total liability, if any, related to the applicable case. We will record our share of any such liability when the responsible party determines a reserve is necessary. At September 30, 2017, no reserves were considered necessary. In addition, the Separation and Distribution Agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our predecessor, The First American Corporation's ("FAC") financial services business, with FAFC and financial responsibility for the obligations and liabilities of FAC's information solutions business with us. Specifically, each party will, and will cause its subsidiaries and affiliates to, indemnify, defend and hold harmless the other party, its respective affiliates and subsidiaries and each of its respective officers, directors, employees and agents for any losses arising out of or otherwise in connection with the liabilities each such party assumed or retained pursuant to the Separation

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations In September 2014, we completed the sale of our collateral solutions and field services businesses, which were included in the former reporting segment Asset Management and Processing Solutions ("AMPS"). In September 2012, we completed the wind down of our consumer services business and our appraisal management company business, which were included in our PI and Risk Management and Work Flow ("RMW") segments, respectively. In September 2011, we closed our marketing services business, which was included in our PI segment. In December 2010, we completed the sale of our Employer and Litigation Services businesses ("ELI"). In connection with previous divestitures, we retain the prospect of contingent liabilities for indemnification obligations or breaches of representations or warranties. With respect to one such divestiture, in September 2016, a jury returned an unfavorable verdict against a discontinued operating unit that, if upheld on appeal, could result in indemnification exposure up to $25.0 million , including interest. We do not consider this outcome to be probable and intend to vigorously assert our contractual and other rights, including to pursue an appeal to eliminate or substantially reduce any potential post-divestiture contingency. Any actual liability that comes to fruition would be reflected in our results from discontinued operations. Each of these businesses is reflected in our accompanying condensed consolidated financial statements as discontinued operations. For the nine months ended September 30, 2017 , we recorded a gain of $4.5 million related to a pre-tax legal settlement in AMPS within our discontinued operations.

Segment Reporting [Abstract]
Segment Information	Segment Information We have organized our reportable segments into two segments: PI and RMW. Property Intelligence . Our PI segment owns or licenses real property information, mortgage information and consumer information, which includes loan information, property sales and characteristic information, property risk and replacement cost, natural hazard data, geospatial data, parcel maps and mortgage-backed securities information. We have also developed proprietary technology and software platforms to access, automate or track our data and assist our clients with compliance regulations. We deliver this information directly to our clients in a standard format over the web, through customizable software platforms or in bulk data form.

Basis of Condensed Consolidat21

Basis of Condensed Consolidated Financial Statements (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Client Concentration	Client Concentration We generate the majority of our revenues from clients with operations in the U.S. residential real estate, mortgage origination and mortgage servicing markets. Approximately 37% and 41% of our operating revenues for the three months ended September 30, 2017 and 2016 , respectively, and 39% and 42% for the nine months ended September 30, 2017 and 2016 , respectively, were generated from our top ten clients, who consist of the largest U.S. mortgage originators and servicers. One of our clients accounted for approximately 11% of our operating revenues for the three months ended September 30, 2017 , and two of our customers accounted for approximately 15% and 11% of our operating revenues for the three months ended September 30, 2016 . Two of our clients accounted for approximately 12% and 10% of our operating revenues for the nine months ended September 30, 2017 and 15% and 12% of our operating revenues for the nine months ended September 30, 2016 .
Reclassification, Policy [Policy Text Block]	Out-of-Period Correction During the second quarter of 2017, we identified a balance sheet misclassification related to certain liability balances, which overstated our accounts payable and accrued expenses and understated other liabilities by approximately $32.0 million as of December 31, 2016. We corrected the balance sheet misclassification error on a prospective basis during the second quarter of 2017 as we determined the misclassification error was not material to the current financial condition or for the prior annual or interim periods.
Comprehensive Income	Comprehensive Income Comprehensive income includes all changes in equity except those resulting from investments by owners and distributions to owners. Specifically, foreign currency translation adjustments, amounts related to supplemental benefit plans, unrealized gains and losses on interest rate swap transactions and unrealized gains and losses on investment are recorded in other comprehensive income/(loss).
Schedule of Accumulated Other Comprehensive Loss	The following table shows the components of accumulated other comprehensive loss, net of taxes as of September 30, 2017 and December 31, 2016 : 2017 2016 Cumulative foreign currency translation $ (95,310 ) $ (118,071 ) Cumulative supplemental benefit plans (4,748 ) (6,267 ) Net unrecognized gains on interest rate swaps 3,541 1,920 Accumulated other comprehensive loss $ (96,517 ) $ (122,418 )
Investment in Affiliates	Investment in Affiliates Investments in affiliates are accounted for under the equity method of accounting when we are deemed to have significant influence over the affiliate but do not control or have a majority voting interest in the affiliate. Investments are carried at the cost of acquisition, including subsequent impairments, capital contributions and loans from us, plus our equity in undistributed earnings or losses since inception of the investment. We recorded equity in losses of affiliates, net of tax of $0.2 million and equity in earnings of affiliates, net of tax of $0.6 million for the three months ended September 30, 2017 and 2016 , respectively, and equity in losses of affiliates, net of tax of $1.2 million and equity in earnings of affiliates, net of tax of $0.6 million for the nine months ended September 30, 2017 and 2016 , respectively. For the three months ended September 30, 2017 and 2016 , we recorded $2.8 million and $2.5 million , respectively, of operating revenues and $3.2 million and $2.9 million , respectively, of operating expenses related to our investment in affiliates. For the nine months ended September 30, 2017 and 2016 , we recorded $6.9 million and $7.7 million , respectively, of operating revenues and $8.9 million and $8.4 million , respectively, of operating expenses related to our investment in affiliates. In June 2017, we acquired a 45.0% interest in Mercury Network, LLC ("Mercury") for $70.0 million , which included a call option to purchase the remaining 55.0% interest within the next nine-month period. We fair-valued the call option using the Black-Scholes model at $4.6 million . In August 2017, we purchased the remaining 55.0% ownership of Mercury for an additional $83.0 million and wrote-off our related call option, which resulted in a net loss of $1.9 million within loss on extinguishment of debt and other, net, in the accompanying consolidated statement of operations for the three months ended September 30, 2017 . See Note 8 - Fair Value of Financial Instruments for further discussion. Prior to our acquisition of the controlling interest, we accounted for the investment in Mercury using the equity method. As of August 2017 we completed the acquisition, see Note 11 - Acquisitions for further discussion.
Tax Escrow Disbursement Arrangements	Tax Escrow Disbursement Arrangements We administer tax escrow disbursements as a service to our clients in connection with our property tax processing solutions. These deposits are maintained in segregated accounts for the benefit of our clients. Tax escrow deposits totaled $1.3 billion as of September 30, 2017 and $619.4 million as of December 31, 2016 . Because these deposits are held on behalf of our clients, they are not our funds and, therefore, are not included in the accompanying condensed consolidated balance sheets. These deposits generally remain in the accounts for a period of two to five business days. We earn interest income or earnings credits from these deposits and bear the cost of bank-related fees. Under our contracts with our clients, if we make a payment in error or fail to pay a taxing authority when a payment is due, we could be held liable to our clients for all or part of the financial loss they suffer as a result of our act or omission. We maintained claim reserves relating to incorrect disposition of assets of $21.2 million and $22.2 million as of September 30, 2017 and December 31, 2016 , respectively, which is reflected in our accompanying condensed consolidated balance sheets as a component of other liabilities.
Pension Plan Buyout	Pension Plan Buyout We have historically offered a variety of employee benefit plans, including a defined benefit pension plan incorporated with the acquisition of RELS (the "RELS Pension Plan"). The RELS Pension Plan offered participants lump sum and annuity payment options based on a number of factors. In October 2016, RELS voted to terminate the RELS Pension Plan effective October 31, 2016. In June 2017, we made a contribution of $13.5 million to settle the defined benefit pension plan incorporated with the acquisition of RELS. We recorded a loss of $6.1 million within loss on extinguishment of debt and other, net in our condensed consolidated statement of operations and cleared the corresponding RELS Pension Plan liability of $9.2 million and corresponding accumulated other comprehensive loss of $1.8 million within our condensed consolidated balance sheets and condensed consolidated statements of comprehensive income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2017, Financial Accounting Standards Board (“FASB”) issued guidance to amend and improve the accounting for hedging activities. The amendment eliminates the requirement to separately measure and report hedge ineffectiveness. An initial quantitative assessment to establish that the hedge is highly effective is still required but the amendment allows until the end of the first quarter it is designated to perform to prepare the assessment. After initial qualification, a qualitative assessment can be performed if the hedge is highly effective and the documentation at inception can reasonably support an expectation of high effectiveness throughout the hedge’s term. The amendment requires companies to present all hedged accounting elements that affect earnings in the same income statement line as the hedged item. For highly effective cash flow hedges, fair value changes will be recorded in other comprehensive income and reclassed to earnings when the hedged item impacts earnings. The guidance is effective prospectively in fiscal years beginning after December 15, 2018. Early adoption is permitted but we do not anticipate to elect early adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In May 2014, the FASB issued updated guidance on revenue recognition in order to i) remove inconsistencies in revenue requirements, ii) provide a better framework for addressing revenue issues, iii) improve comparability across entities, industries, jurisdictions, and capital markets, iv) provide more useful information through improved disclosures, and v) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. Under the amendment, an entity should recognize revenue to depict the transfer of promised goods or services to clients in the amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting treatment for the incremental costs of obtaining a contract, which would not have been incurred had the contract not been obtained. Further, an entity is required to disclose sufficient information to enable the user of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows from contracts with clients. The updated guidance provides two methods of adoption: i) retrospective application to each prior reporting period presented, or ii) recognition of the cumulative effect from the retrospective application at the date of initial application. We elected the modified retrospective approach. As updated by FASB in August 2015, the guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Earlier adoption was permitted for annual reporting periods beginning after December 15, 2016 but we did not elect early adoption. Accordingly, we will adopt the new standard as of January 1, 2018. In adopting the updated guidance, we are implementing changes to our accounting policies, business and contract-management processes. We anticipate that our notes to the consolidated financial statements related to revenue recognition will be expanded and the most substantial change to our consolidated financial statements will be a net increase to total deferred revenue of approximately 5% , primarily within our Risk Management and Work Flow (“RMW”) reporting segment, in the initial year of adoption. The expected increase to deferred revenue is principally driven by a change in the accounting for contracts with future discounts that give rise to material rights. Under the current standard, these future discounts are recognized at a point-in-time whereas, under the updated guidance, a portion of the consideration is allocated to material rights and recognized when the future goods or services are transferred. The cumulative impact of all changes to stockholders’ equity is expected to be a net reduction of approximately 5% upon implementation. Further, the updated guidance is not expected to materially impact our revenues and results of operations in the upcoming fiscal years and interim periods. However, we are still in the process of updating our systems and financial controls and continue to review the presentation of our consolidated financial statements and related disclosures required by the updated guidance.
