Organization, Consolidation and Presentation of Financial Statements [Abstract]
Concentration Risk, Credit Risk, Policy [Policy Text Block]	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 43.0% and 20.0% of our operating revenues for the three months ended March 31, 2016 and 2015, respectively, were generated from our ten largest clients, who consist of the largest U.S. mortgage originators and servicers. Two of our clients accounted for 14.0% and 12.0% of our operating revenues for the three months ended March 31, 2016. No client accounted for 10.0% or more of our operating revenues for the three months ended March 31, 2015.
Comprehensive Income, Policy [Policy Text Block]	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.
Marketable Securities, Policy [Policy Text Block]	Marketable Securities Debt securities are carried at fair value and consist primarily of investments in obligations of various corporations and mortgage-backed securities. Equity securities are carried at fair value and consist primarily of investments in marketable common and preferred stock. We classify our publicly traded debt and equity securities as available-for-sale and carry them at fair value with unrealized gains or losses classified as a component of accumulated other comprehensive loss. As of March 31, 2016 and December 31, 2015, our marketable securities consisted primarily of investments in preferred stock of $23.3 million and $22.7 million, respectively. There were no gains or losses recognized on sales of marketable securities for the three months ended March 31, 2016 and 2015.
Mandatorily Redeemable Noncontrolling Interest [Policy Text Block]	Mandatorily Redeemable Noncontrolling Interest Mandatorily redeemable noncontrolling interests for which there is a contractual requirement for purchasing the interest are included as a liability of NZD$27.8 million, or $19.0 million, in our accompanying condensed consolidated balance sheet as of December 31, 2015. In January 2016 we acquired the remaining 40.0% interest in New Zealand-based Property IQ Ltd. ("PIQ") and settled the mandatorily redeemable noncontrolling interest as of March 31, 2016. See Note 12 - Acquisitions for further discussion.
Escrow Administration Arrangements [Policy Text Block]	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. Tax escrow deposits totaled $5.4 billion as of March 31, 2016 and $340.3 million as of December 31, 2015. 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 and we invest the funds in a highly-rated, liquid investment, such as bank deposit products or AAA-rated money market funds. We earn interest income or earnings credits from these investments and bear the risk of any losses. However, we have not historically incurred any investment losses and do not anticipate incurring any future investment losses. As a result, we do not maintain any reserves for losses in value of these investments. 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 $19.7 million and $21.2 million as of March 31, 2016 and December 31, 2015, respectively, which is reflected in our accompanying condensed consolidated balance sheets.
