Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statements	The financial information in this report presented for interim periods is unaudited and includes the accounts of Fidelity National Financial, Inc. and its subsidiaries (collectively, “we,” “us,” “our,” the "Company" or “FNF”) prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All adjustments made were of a normal, recurring nature. This report should be read in conjunction with our Annual Report on Form 10-K (our "Annual Report") for the year ended December 31, 2023.
Earnings Per Share	Earnings Per Share Basic earnings per share, as presented on the unaudited Condensed Consolidated Statement of Earnings, is computed by dividing net earnings available to common shareholders in a given period by the weighted average number of common shares outstanding during such period. In periods when earnings are positive, diluted earnings per share is calculated by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding plus assumed conversions of potentially dilutive securities. For periods when we recognize a net loss, diluted loss per share is equal to basic loss per share as the impact of assumed conversions of potentially dilutive securities is considered to be antidilutive. We have granted certain stock options and shares of restricted stock, which have been treated as common share equivalents for purposes of calculating diluted earnings per share for periods in which positive earnings have been reported. Options or other instruments, which provide the ability to purchase shares of our common stock that are antidilutive, are excluded from the computation of diluted earnings per share. There were no antidilutive instruments outstanding during the three and nine months ended September 30, 2024. There were fewer than 1 million antidilutive instruments outstanding during the three and nine months ended September 30, 2023.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Pronouncements In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-02, Accounting for Investments in Tax Credit Structure Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force). The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. We adopted this standard on January 1, 2024, as required, and there was no material impact to our unaudited Condensed Consolidated Financial Statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments in this update affect all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction and clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. Additionally, the amendments require the following disclosures for equity securities subject to contractual sale restrictions: the fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet, the nature and remaining duration of the restriction(s), and the circumstances that could cause a lapse in the restriction(s). The amendments in this update do not change the principles of fair value measurement, rather, they clarify those principles when measuring the fair value of an equity security subject to a contractual sale restriction and improve current GAAP by reducing diversity in practice, reducing the cost and complexity in measuring fair value, and increasing comparability of financial information across reporting entities that hold those investments. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. We adopted this standard as of January 1, 2024, and it did not have a material impact on our unaudited Condensed Consolidated Financial Statements and related disclosures upon adoption. Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expense categories that are regularly provided to the chief operating decision maker (CODM) and included in each reported measure of a segment’s profit or loss. In addition, the amendments enhance interim disclosure requirements that are currently required annually, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, and contain other disclosure requirements. The amendments in this update are incremental to the current requirements of Topic 280 and do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The enhanced segment disclosure requirements apply retrospectively to all prior periods presented in the financial statements. The significant segment expense and other segment item amounts disclosed in prior periods shall be based on the significant segment expense categories identified and disclosed in the period of adoption. The amendments in this update are effective for all public entities for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted, and the updates must be applied retrospectively to all periods presented in the financial statements. We did not early adopt this standard and are in the process of assessing its impact on our disclosures upon adoption. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this update enhance the transparency of the income tax disclosures by expanding on the disclosures required annually. The amendments require entities to disclose in their rate reconciliation table additional categories of information about federal, state, and foreign income taxes, in addition to providing details about the reconciling items in some categories if above a quantitative threshold. Additionally, the amendments require annual disclosure of income taxes paid (net of refunds received) disaggregated by jurisdiction based on a quantitative threshold. The amendments in this update are effective for public business entities for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments should be applied on a prospective basis, however, retrospective application is permitted. We do not currently expect to early adopt this standard and are in the process of assessing its impact on our disclosures upon adoption. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): The amendment in this update enhances the transparency of certain expense captions by disclosing more granular information of specific expenses within those captions such as personnel cost, depreciation and amortization. The amendment also requires additional qualitative descriptions of such expenses. The amendments in this update are effective for public business entities for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to all prior periods presented in the financial statements. We are currently evaluating our adoption timing and are in the process of assessing its impact on our disclosures upon adoption.
Market Risk Benefits (“MRBs”)	Market Risk Benefits (“MRBs”) MRBs are contracts or contract features that both provide protection to the contract holder from other-than-nominal capital market risk (equity, interest rate, and foreign exchange risk) and expose the Company to other-than-nominal capital market risk. MRBs include certain contract features primarily on fixed index annuity ("FIA") products that provide minimum guarantees to policyholders, such as guaranteed minimum death benefit, guaranteed minimum withdrawal benefit (“GMWB”) riders, and guaranteed minimum accumulation benefit riders. In certain reinsurance transactions, the underlying risks ceded to a reinsurer contain MRBs. MRBs (inclusive of reinsured MRBs) are measured at fair value using an attributed fee measurement approach, where attributed fees are explicit rider charges collectible from the policyholder (or paid to the reinsurer) used to cover the excess benefits, which represent expected benefits in excess of the policyholder’s account value. At contract inception, an attributed fee ratio is calculated equal to rider charges over benefits paid in excess of the account value attributable to the MRBs. The attributed fee ratio remains static over the life of the MRBs and is capped at 100%. Each period subsequent to contract inception, the attributed fee ratio is used to calculate the fair value of the MRBs using a risk neutral valuation method and is based on current net amounts at risk, market data, internal and industry experience, and other factors. The balances are computed using assumptions including mortality, full and partial surrender, GMWB utilization, risk-free rates including non-performance spread and risk margin, market value of options, and economic scenarios. Policyholder behavior assumptions are reviewed at least annually, typically in the third quarter, for any revisions. Reinsured MRBs are valued using a methodology consistent with direct MRBs, with the exception of the non-performance spread, which reflects the credit of the reinsurer. MRBs can either be in an asset or liability position and are presented separately on the unaudited Condensed Consolidated Balance Sheets as the right of setoff criteria are not met. Changes in fair value, net, are recognized in Market risk benefits (gains) losses in the unaudited Condensed Consolidated Statements of Earnings, except for the change in fair value due to a change in our instrument-specific credit risk, which is recognized in the unaudited Condensed Consolidated Statements of Comprehensive Earnings. See a description of the fair value methodology used in Note C Fair Value of Financial Instruments and Note P Market Risk Benefits.
Revenue Recognition	Our Direct title insurance premiums are recognized as revenue at the time of closing of the underlying transaction as the earnings process is then considered complete. Regulation of title insurance rates varies by state. Premiums are charged to customers based on rates predetermined in coordination with each states' respective Department of Insurance. Cash associated with such revenue is typically collected at closing of the underlying real estate transaction. Premium revenues from agency title operations are recognized when the underlying title order and transaction closing, if applicable, are complete. Revenues from our home warranty business are generated from contracts with customers to provide warranty for major home appliances. Substantially all of our home warranty contracts are one year in length and revenue is recognized ratably over the term of the contract.
Revenue Recognition, Services, Real Estate Transactions	Escrow fees and other title-related fees and income in our Title segment are closely related to Direct title insurance premiums and are primarily associated with managing the closing of real estate transactions, including the processing of funds on behalf of the transaction participants, gathering and recording the required closing documents, providing notary and home inspection services, and other real estate or title-related activities. Revenue is primarily recognized upon closing of the underlying real estate transaction or completion of services. Cash associated with such revenue is typically collected at closing. Revenues from ServiceLink, excluding its title premiums, escrow fees and loan subservicing fees primarily include revenues from real estate appraisal services and foreclosure processing and facilitation services. Revenues from real estate appraisal services are recognized when all appraisal work is complete, a final report is issued to the client and the client is billed. Revenues from foreclosure processing and facilitation services are primarily recognized upon completion of the services and when billing to the client is complete. Life insurance premiums in our F&G segment reflect premiums for life-contingent PRT, traditional life insurance products, and life-contingent immediate annuity products, which are recognized as revenue when due from the policyholder. We have ceded the majority of our traditional life business to unaffiliated third party reinsurers. While the base contract has been reinsured, we continue to retain the return of premium rider. Insurance and investment product fees and other consist primarily of the cost of insurance on IUL policies, unearned revenue liabilities ("URL") on IUL policies, policy rider fees primarily on FIA policies and surrender charges assessed against policy withdrawals in excess of the policyholder's allowable penalty-free amounts. Premium and annuity deposit collections for indexed annuities, fixed rate annuities, immediate annuities and PRT without life contingency, and amounts received for funding agreements are reported in the financial statements as deposit liabilities (i.e., contractholder funds) instead of as sales or revenues. Similarly, cash payments to customers are reported as decreases in the liability for contractholder funds and not as expenses. Sources of revenues for products accounted for as deposit liabilities include net investment income, surrender, cost of insurance and other charges deducted from contractholder funds, and net realized gains (losses) on investments. Components of expenses for products accounted for as deposit liabilities are interest-sensitive and index product benefits (primarily interest credited to account balances or the hedging cost of providing index credits to the policyholder), amortization of value of business acquired ("VOBA"), deferred acquisition costs ("DAC") and deferred sales inducements ("DSI"), other operating costs and expenses, and income taxes. Real estate technology revenues are primarily comprised of subscription fees for use of software provided to real estate professionals. Subscriptions are only offered on a month-by-month basis and fees are billed monthly. Revenue is recognized in the month services are provided. Loan subservicing revenues are generated by certain subsidiaries of ServiceLink and are associated with the servicing of mortgage loans on behalf of its customers. Revenue is recognized when the underlying work is performed and billed. Loan subservicing revenues are subject to the recognition requirements of ASC Topic 860.
Revenue Recognition, Other	We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, primarily related to revenue from our home warranty business, and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
