Organization, Consolidation and Presentation of Financial Statements [Abstract]
Client Concentration	Client Concentration We generate the majority of our operating revenues from clients with operations in the US residential real estate, mortgage origination and mortgage servicing markets. Approximately 31% and 32% of our operating revenues for the three months ended September 30, 2019 and 2018, respectively, were generated from our top ten clients, who consist of the largest US mortgage originators and servicers. None of our clients individually accounted for greater than 10% of our operating revenues for the three months ended September 30, 2019 nor 2018. Approximately 30% and 32% of our operating revenues for the nine months ended September 30, 2019 and 2018, respectively, were generated from our top ten clients with none of our clients individually accounting for greater than 10% of our operating revenues during these periods.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Cash, Cash Equivalents and Restricted Cash We deem the carrying value of cash, cash equivalents and restricted cash to be a reasonable estimate of fair value due to the nature of these instruments. Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit/bank guarantees secured by us, escrow accounts due to acquisitions and divestitures as well as short-term investments within our deferred compensation plan trust. The following table provides a reconciliation of cash, cash equivalents and restricted cash to amounts shown in the statement of cash flows:
Operating Revenue Recognition	Operating Revenue Recognition We derive our operating revenues primarily from US mortgage lenders, servicers and insurance companies with good creditworthiness. Operating revenue arrangements are written and specify the products or services to be delivered, pricing, and payment terms. Operating revenue is recognized when the distinct good, service, or performance obligation is delivered and control has been transferred to the client. Generally, clients contract with us to provide products and services that are highly interrelated and not separately identifiable. Therefore, the entire contract is accounted for as one performance obligation. At times, some of our contracts have multiple performance obligations where we allocate the total price to each performance obligation based on the estimated relative standalone selling price using observable sales or the cost-plus-margin approach. For products or services where delivery occurs at a point in time, we recognize operating revenue when the client obtains control of the products upon delivery. When delivery occurs over time, we generally recognize operating revenue ratably over the service period, once initial delivery has occurred. For certain of our products or services, clients may also pay upfront fees, which we defer and recognize as operating revenue over the longer of the contractual term or the expected client relationship period. Licensing arrangements that provide our clients with the right to access or use our intellectual property are considered functional licenses for which we generally recognize operating revenue based on usage. For arrangements that provide a stand-ready obligation or substantive updates to the intellectual property which the client is contractually or practically required to use, we recognize operating revenue ratably over the contractual term. Client payment terms are standard with no significant financing components or extended payment terms granted. In limited cases, we allow for client cancellations for which we estimate a reserve. See further discussion in Note 8 - Operating Revenues.
Comprehensive Income	Comprehensive Loss Comprehensive loss includes all changes in equity except those resulting from investments by shareholders and distributions to shareholders. Specifically, foreign currency translation adjustments, amounts related to supplemental benefit plans, unrealized gains and losses on interest rate swap transactions and investments are recorded in other comprehensive income/(loss).
Investment in Affiliates, net	Investment in Affiliates, net 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, less dividends received. For the three and nine months ended September 30, 2019, we did not have any operating revenues related to our investment in affiliates and had $0.3 million and $0.9 million for the three and nine months ended September 30, 2018, respectively. We recorded operating expenses of $0.4 million and $1.0 million related to our investment in affiliates for the three months ended September 30, 2019 and 2018, respectively, and $1.1 million and $6.3 million for the nine months ended September 30, 2019 and 2018, respectively. During the three and nine months ended September 30, 2019, we recorded a non-cash impairment charge of $1.5 million in our investment in affiliates, net, due to an other-than-temporary loss because we do not foresee an ability to recover the carrying amount of the investment. This loss was recorded within gain/(loss) on investments and other, net in our condensed consolidated statements of operations. No such impairments were recorded in the three and nine months ended September 30, 2018. As of September 30, 2019, and December 31, 2018, we had insignificant accounts payable and accounts receivable with these affiliates.
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. In September 2012, we completed the wind-down of our consumer services business and our former appraisal management company business. In September 2011, we closed our marketing services business. In December 2010, we completed the sale of our Employer and Litigation Services businesses. In connection with previous divestitures, we retained certain contingent liabilities of the businesses that were disposed of. These contingent liabilities include, among other items, liability for certain litigation matters, indemnification obligations and potential breaches of representations or warranties. With respect to our Employer and Litigation Services divestiture, we retained certain liabilities and, in September 2016, a jury returned an unfavorable verdict against this discontinued operating unit, which we appealed. In August 2019, the verdict was upheld on appeal. We have accrued a potential loss of $21.7 million as of September 30, 2019 with respect to this verdict, although we are pursuing further review of the verdict. The liability is reflected in our results from discontinued operations. As of September 30, 2019, and December 31, 2018, we recorded assets of discontinued operations of $6.3 million and $0.6 million, respectively, within prepaid expenses and other current assets within our condensed consolidated balance sheets, mainly consisting of tax-related assets. Additionally, as of September 30, 2019 and December 31, 2018, we recorded liabilities of $24.1 million and $2.2 million, respectively, within accounts payable and other accrued expenses, which mainly consisted of legal-related accruals
Tax Escrow Disbursement Arrangements	Tax Escrow Disbursement Arrangements We administer tax escrow disbursements as a service to our clients in connection with our tax services business. These deposits are maintained in segregated accounts for the benefit of our clients and totaled $1.3 billion and $0.7 billion as of September 30, 2019 and December 31, 2018, respectively. 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 record credits from these activities as a reduction to related administrative expenses, including the cost of bank fees and other administration costs. 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 total claim reserves relating to incorrect disposition of assets of $21.4 million and $21.2 million as of September 30, 2019 and December 31, 2018, respectively. Within these amounts, $9.3 million and $9.2 million, respectively, are short-term and are reflected within accounts payable and other accrued expenses within our accompanying condensed consolidated balance sheets. The remaining reserves are reflected within other liabilities.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2019, the Financial Accounting Standards Board (“FASB”) issued guidance to amend or clarify certain areas within three previously issued standards related to financial instruments which includes clarification for fair value using the measurement alternative, measuring credit losses and accounting for derivatives and hedging. The amendments in this guidance are largely effective for fiscal years beginning after December 15, 2019 with early adoption permitted. We have not elected early adoption and do not anticipate that this guidance will have a material impact on our consolidated financial statements. In August 2017, the 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 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 loss and reclassified to earnings when the hedged item impacts earnings. The guidance became effective prospectively for fiscal years beginning after December 15, 2018. In October 2018, the FASB issued incremental guidance to this update to permit the Overnight Index Swap Rate and the Secured Overnight Financing Rate to be utilized as US benchmark interest rates for hedge accounting purposes. We have adopted this guidance beginning with fiscal year 2019 as required, which has not had a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance on lease accounting which requires leases, regardless of classification, to be recognized on the balance sheet as lease assets and liabilities. The objective of this standard is to provide greater transparency on the amount, timing and uncertainty of cash flows arising from leasing arrangements. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee depends upon its classification as a finance or operating lease. On January 1, 2019, we adopted the new lease accounting standard, and all related amendments, using the modified retrospective approach. Comparative information has not been restated and continues to be reported under the standards in effect for those prior periods as allowed by the guidance. As part of our adoption we elected the package of practical expedients permitted under the transition guidance which allows us to carry forward our historical lease classification of pre-existing leases, treatment of pre-existing indirect costs, as well as our conclusions of whether a pre-existing contract contains a lease. We have implemented internal controls to enable the preparation of financial information upon our adoption in the first quarter of 2019. Adoption of the new lease accounting standard resulted in the recording of operating lease assets and lease liabilities of approximately $67.7 million and $103.9 million, respectively, as of January 1, 2019. There was no impact to opening equity as a result of adoption as the difference between the asset and liability balance is attributable to reclassifications of pre-existing balances, such as deferred and prepaid rent, into the lease asset balance. The adoption of this standard has not materially impacted our consolidated statement of operations or presentation of cash flows and we do not anticipate a material impact in the future based on our current operations.
Leases	Leases We determine if an arrangement contains a lease at inception and determine the classification of the lease, as either operating or finance, at commencement. Operating and finance lease assets and liabilities are recorded based on the present value of future lease payments which factors in certain qualifying initial direct costs incurred as well as any lease incentives received. If an implicit rate is not readily determinable, we utilize our incremental borrowing rate and inputs from third-party lenders to determine the appropriate discount rate. Lease expense for operating lease payments are recognized on a straight-line basis over the lease term. Finance leases incur interest expense using the effective interest method in addition to amortization of the leased asset on a straight-line basis, both over the applicable lease term. Lease terms may factor in options to extend or terminate the lease. We adhere to the short-term lease recognition exemption for all classes of assets (i.e. facilities and equipment). As a result, leases with an initial term of twelve months or less are not recorded on the balance sheet and are recognized on a straight-line basis over the lease term. In addition, for certain equipment leases, we account for lease and non-lease components, such as services, as a single lease component as permitted.

Cash, Cash Equivalents and Restricted Cash

We deem the carrying value of cash, cash equivalents and restricted cash to be a reasonable estimate of fair value due to the nature of these instruments.
