Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation – The accompanying Consolidated Financial Statements include the accounts and operations of Investors Title Company and its subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Earnings attributable to noncontrolling interests in majority-owned insurance agencies, including redeemable noncontrolling interests, are recorded in the Consolidated Statements of Income. Noncontrolling interests representing the portion of equity not related to the Company's ownership interests are recorded in separate sections of the Consolidated Balance Sheets. All intercompany balances and transactions have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents For the purpose of presentation in the Company’s Consolidated Statements of Cash Flows, cash equivalents are highly liquid instruments with remaining original maturities of three months or less. The carrying amount of cash and cash equivalents is a reasonable estimate of fair value due to the short-term maturity at purchase of these instruments.
Investments in Securities	Investments in Securities Securities for which the Company has the intent and ability to hold to maturity are classified as held-to-maturity and reported at cost, adjusted for amortization of premiums or accretion of discounts, and other-than-temporary declines in fair value. Securities held principally for resale in the near term are classified as trading securities and recorded at fair values. Realized and unrealized gains and losses on trading securities are included in other income. Securities not classified as either trading or held-to-maturity are classified as available-for-sale and reported at fair value with unrealized gains and losses, net of tax and adjusted for other-than-temporary declines in fair value, reported as accumulated other comprehensive income. As of December 31, 2015 and 2014, all investments in securities are classified as available-for-sale. Securities are regularly reviewed for differences between the cost and estimated fair value of each security for factors that may indicate that a decline in fair value is other-than-temporary. Some factors considered in evaluating whether or not a decline in fair value is other-than-temporary include the duration and extent to which the fair value has been less than cost and the Company’s ability and intent to retain the investment for a period of time sufficient to allow for a recovery in value. Such reviews are inherently uncertain and the value of the investment may not fully recover or may decline in future periods resulting in a realized loss. Fair values of the majority of investments are based on quoted market prices. Realized gains and losses are determined on the specific identification method. Refer to Note 3 for further information regarding investments in securities and fair value.
Short-term Investments	Short-term Investments Short-term investments are comprised of money market accounts which are invested in short-term funds, time deposits with banks and savings and loan associations, and other investments expected to have maturities or redemptions greater than three months and less than twelve months. The Company monitors any events or changes in circumstances that may have a significant adverse effect on the fair value of these investments.
Other Investments	Other Investments Other investments consist primarily of investments in title insurance agencies structured as limited liability companies (“LLCs”), which are accounted for under the equity or cost methods of accounting. The aggregate cost of the Company’s cost method investments totaled $3,572,914 and $2,423,408 at December 31, 2015 and 2014, respectively. The Company monitors any events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments and makes any necessary adjustments.
Property Acquired in Settlement of Claims	Property Acquired in Settlement of Claims Property acquired in settlement of claims is held for sale and valued at the lower of cost or market. Adjustments to reported estimated realizable values and realized gains or losses on dispositions are recorded as increases or decreases in claim costs. Properties acquired in settlement of claims are included in prepaid expenses and other assets in the Consolidated Balance Sheets.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and are depreciated principally under the straight-line method over the estimated useful lives (3 to 25 years) of the respective assets. Maintenance and repairs are charged to operating expenses and improvements are capitalized.
Reserves for Claims	Reserves for Claims Total reserves for all reported and unreported losses the Company incurred through December 31, 2015 are represented by the reserves for claims. The Company’s reserves for unpaid losses and loss adjustment expenses are established using estimated amounts required to settle claims for which notice has been received (reported) and the amount estimated to be required to satisfy incurred claims of policyholders which may be reported in the future. Despite the variability of such estimates, management believes that the reserves are adequate to cover claim losses resulting from pending and future claims for policies issued through December 31, 2015. The Company continually reviews and adjusts its reserve estimates as necessary to reflect its loss experience and any new information that becomes available. Adjustments resulting from such reviews may be significant. Claims and losses paid are charged to the reserves for claims. Although claims losses are typically paid in cash, occasionally claims are settled by purchasing the interest of the insured or the claimant in the real property. When this event occurs, the acquiring company carries assets at the lower of cost or estimated realizable value, net of any indebtedness on the property.
Income Taxes	Income Taxes The Company makes certain estimates and judgments in determining income tax expense (benefit) for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. The Company provides for deferred income taxes (benefits) for the tax consequences in future years of temporary differences between the financial statements’ carrying values and the tax bases of assets and liabilities using currently enacted tax rates. The Company establishes a valuation allowance if it believes that it is more likely than not that some or all of its deferred tax assets will not be realized. Refer to Note 8 for further information regarding income taxes.
Premiums Written and Commissions to Agents	Premiums Written and Commissions to Agents Generally, title insurance premiums are recognized at the time of closing of the related real estate transaction, as the earnings process is then considered complete. Policies or commitments are issued upon receipt of final certificates or preliminary reports with respect to titles. Title insurance commissions earned by the Company’s agents, taxes and a provision for claims losses are recognized as expenses concurrent with recognition of related premium revenue.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Company management continually evaluates the collectability of receivables and provides an allowance for doubtful accounts equal to estimated losses expected to be incurred in the collection of premiums and fees receivable. Changes to the allowance for doubtful accounts are reflected within net premiums written in the Consolidated Statements of Income. Amounts are charged off in the period they are deemed to be uncollectible. Quarterly, the Company evaluates the collectability of receivables. Premiums not collected within 7 months are fully reserved. Write-offs of receivables have not been material to the Company.
Exchange Services Revenue	Exchange Services Revenue Fees are recognized at the signing of a binding agreement and investment earnings are recognized as they are earned. Exchange services revenues are included in other revenues in the Consolidated Statements of Income.
Fair Values of Financial Instruments	Fair Values of Financial Instruments The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, short-term investments, premium and fees receivable, accrued interest and dividends, accounts payable, commissions payable, reinsurance payable and current income taxes recoverable/payable approximate fair value due to the short-term nature of these assets and liabilities. Estimated fair values for the majority of investment securities are based on quoted market prices. Auction rate securities (“ARS”) are valued using discounted cash flow models to determine the estimated fair value of these investments. Some of the inputs for determining the fair value of ARS are unobservable in the securities markets and are significant. Refer to Note 3 for further information regarding investments in securities and fair value.
Comprehensive Income	Comprehensive Income The Company’s accumulated other comprehensive income is comprised of unrealized holding gains/losses on available-for-sale securities, net of tax, and unrecognized prior service cost and unrealized gains/losses associated with postretirement benefit liabilities, net of tax. Accumulated other comprehensive income as of December 31, 2015 consists of $11,597,741 of unrealized holding gains on available-for-sale securities and $114,726 of unrecognized prior service cost and unrecognized actuarial losses associated with postretirement benefit liabilities. Accumulated other comprehensive income as of December 31, 2014 consists of $12,934,497 of unrealized holding gains on available-for-sale securities and $77,988 of unrecognized prior service cost and unrecognized actuarial losses associated with postretirement benefit liabilities. Accumulated other comprehensive income as of December 31, 2013 consists of $11,395,757 of unrealized holding gains on available-for-sale securities and $48,353 of unrecognized prior service cost and unrecognized actuarial losses associated with postretirement benefit liabilities.
Share-Based Compensation	Share-Based Compensation The Company accounts for share-based compensation in accordance with the fair value based principles required by the Financial Accounting Standards Board (“FASB”). Share-based compensation cost is generally measured at the grant date, based on the estimated fair value of the award, and is recognized as an expense over the employee’s requisite service period. As the share-based compensation expense recognized in the Consolidated Statements of Income is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Other Intangible Assets	Other Intangible Assets The Company’s other intangible assets consist of a non-compete agreement and referral relationships resulting from an agency acquisition and are recorded at the acquisition date fair value. The referral relationships are amortized on a straight-line basis over the useful life and amortization of the non-compete contract will start at a future date when the related employment agreement is terminated. Intangible assets are reviewed for impairment at least quarterly.
Subsequent Events	Subsequent Events The Company has evaluated and concluded that there were no material subsequent events requiring adjustment or disclosure to its Consolidated Financial Statements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the FASB updated guidance to improve financial reporting for leasing transactions. The core principle of the guidance is that lessees will be required to recognize assets and liabilities on the balance sheet for all leases with terms of more than 12 months. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. The accounting applied by a lessor is largely unchanged from current GAAP, with some targeted improvements. Disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. In transition, both lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The amendments of this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact that the recently issued accounting standard will have on the Company's financial position and results of operations, and is currently uncertain as to whether it will have a material effect. In January 2016, the FASB updated guidance to enhance the reporting model for financial instruments. Among the main principles of the guidance applicable to the Company are provisions to require equity investments, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income; simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, noting that when a qualitative assessment indicates that impairment exists that an entity is required to measure the investment at fair value; eliminate the requirement to disclose methods and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost; require entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; require separate presentation of financial assets and financial liabilities by measuring category and form of financial asset on the balance sheet or accompanying notes to the financial statements; and clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments of this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will be required to apply the amendments of this update by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with the amendments related to equity securities without readily determinable fair values being applied prospectively to equity investments that exist as of the date of adoption. The guidance is expected to have a material impact on the Company’s financial condition and results of operations once effective, primarily resulting from fluctuations in security exchanges or markets. In February 2015, the FASB updated guidance to change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities; eliminate the presumption that a general partner should consolidate a limited partnership; affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and provide a scope exception from consolidation guidance for reporting entities that are required to comply with or operate in accordance with certain requirements similar to those for registered money market funds. For public entities, this update becomes effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted. The Company is currently evaluating the impact that the recently issued accounting standard will have on the Company's financial position and results of operations, but does not expect it to have a material impact. In May 2014, the FASB updated guidance to improve the comparability of revenue recognition practices for entities that either enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards such as insurance contracts or lease standards. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For public entities, this update originally became effective for interim and annual reporting periods beginning after December 15, 2016. In August 2015, the FASB updated guidance to defer the effective date of the standard by one year. Early adoption is not permitted, although public entities are permitted to elect to adopt the amendments on the original effective date. The Company is currently evaluating the impact that the recently issued accounting standard will have on the Company's financial position and results of operations, but does not expect it to have a material impact.
Use Of Estimates and Assumptions	Use of Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period and accompanying notes. Actual results could differ materially from those estimates and assumptions used. The more significant of these estimates and assumptions include the following: Claims – The Company’s reserves for claims are established using estimated amounts required to settle claims for which notice has been received (reported) and the amount estimated to be required to satisfy incurred claims of policyholders which may be reported in the future (incurred but not reported, or “IBNR”). A provision for estimated future claims payments is recorded at the time policy revenue is recorded as a percentage of premium income. By their nature, title claims can often be complex, vary greatly in dollar amounts, vary in number due to economic and market conditions such as an increase in mortgage foreclosures, and involve uncertainties as to ultimate exposure. In addition, some claims may require a number of years to settle and determine the final liability for indemnity and loss adjustment expense. The payment experience may extend for more than 20 years after the issuance of a policy. Events such as fraud, defalcation and multiple property defects can substantially and unexpectedly cause increases in estimates of losses. Due to the length of time over which claim payments are made and regularly occurring changes in underlying economic and market conditions, these estimates are subject to variability. Management considers factors such as the Company’s historical claims experience, case reserve estimates on reported claims, large claims, actuarial projections and other relevant factors in determining loss provision rates and the aggregate recorded expected liability for claims. In establishing reserves, actuarial projections are compared with recorded reserves to evaluate the adequacy of such recorded claims reserves and any necessary adjustments are then recorded in current operations. As the most recent claims experience develops and new information becomes available, the loss reserve estimate related to prior periods will change to more accurately reflect updated and improved emerging data. The Company reflects any adjustments to reserves in the results of operations in the period in which new information (principally claims experience) becomes available. The Company’s reserves for claims are established using estimated amounts required to settle claims for which notice has been received (reported) and the amount estimated to be required to satisfy incurred claims of policyholders which have been incurred but not reported (“IBNR”). During the third quarter of 2013 certain actuarial inputs were changed to reflect recent trends. See Note 6 in the accompanying Consolidated Financial Statements for further information regarding this change in accounting estimate. Premiums written – The Company’s premium revenues from certain agency operations include accruals based on estimates. These accruals estimate unreported agency premiums related to transactions which have settled as of the balance sheet date. Accruals for premiums from certain agencies are necessary because of the lag between policy effective dates and the reporting of these transactions to the Company by the agents. The current lag time used in the Company’s estimates typically ranges between 0 and 180 days after the policy effective date, with the majority of agencies reporting within 60 to 90 days. The lag time is reviewed periodically to monitor accruals. To determine the estimated premiums, the Company uses historical experience, as well as other factors, to make certain assumptions about the average elapsed time between the policy effective date and the date the policies are reported. From time to time, the Company adjusts the inputs to the calculation of these estimates as agents report transactions and information on more current trends becomes available. The Company reflects any adjustments to the accruals in the results of operations in the period in which new information becomes available. Impairments – Securities are regularly evaluated and reviewed for differences between the cost and estimated fair value of each security for factors that may indicate that a decline in estimated fair value is other-than-temporary. When, in the opinion of management, a decline in the estimated fair value of an investment is considered to be other-than-temporary, such investment is written down to its estimated fair value. Some factors considered in evaluating whether or not a decline in estimated fair value is other-than-temporary include the duration and extent to which the estimated fair value has been less than cost; the probability that the Company will be unable to collect all amounts due under the contractual terms of the security; with respect to equity securities, whether the Company’s ability and intent to retain the investment for a period of time is sufficient to allow for a recovery in value; with respect to fixed maturity securities, whether the Company has the intent to sell or will more likely than not be required to sell a particular security before recovery in value; and the financial condition and prospects of the issuer (including credit ratings). These factors are reviewed quarterly and any material degradation in the prospect for recovery will be considered in the other-than-temporary impairment analysis. Such reviews are inherently uncertain and the value of the investment may not fully recover or may decline in future periods resulting in a realized loss. The estimated fair values of the majority of the Company’s investments are based on quoted market prices from independent pricing services.
