Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, the interim data includes all normal recurring adjustments considered necessary to fairly state the results for the interim periods presented. The preparation of interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of our interim condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Intercompany and inter-segment transactions and accounts have been eliminated in consolidation. Certain prior year amounts reported by the Mortgage Services and Technology Services segments have been reclassified to conform with the current year presentation. The Mortgage Partnership of America, L.L.C. (“MPA”), a wholly-owned subsidiary of Altisource, serves as the manager of Best Partners Mortgage Cooperative, Inc., doing business as the Lenders One^® mortgage cooperative (“Lenders One”). MPA provides services to Lenders One under a management agreement that ends on December 31, 2025. The management agreement between MPA and Lenders One, pursuant to which MPA is the management company of Lenders One, represents a variable interest in a variable interest entity. MPA is the primary beneficiary of Lenders One as it has the power to direct the activities that most significantly impact Lenders One’s economic performance and the right to receive benefits from Lenders One. As a result, Lenders One is presented in the accompanying condensed consolidated financial statements on a consolidated basis with the interests of the members reflected as non-controlling interests. As of September 30, 2015, Lenders One had total assets of $4.2 million and total liabilities of $2.9 million. As of December 31, 2014, Lenders One had total assets of $7.7 million and total liabilities of $6.7 million. In September 2014, Best Partners Mortgage Brokers Cooperative, Inc. was launched, doing business as the Wholesale One^™ Mortgage Cooperative (“Wholesale One”), for the wholesale mortgage industry. Wholesale One assists mortgage brokers and wholesale lenders with tools to improve their businesses. In April 2015, Best Partners Residential Investor Cooperative, Inc. was launched, doing business as the Residential Investor One^™cooperative (“Residential Investor One”). Residential Investor One was formed to deliver savings and efficiencies to individual and institutional residential real estate investors. MPA provides services to both Wholesale One and Residential Investor One under management agreements that end on July 8, 2039 (with automatic renewals for three successive five year periods) and March 12, 2040 (with automatic renewals for three successive five year periods), respectively. Such management agreements between MPA and the respective cooperative, together with the membership agreements that each of the members signs with the respective cooperative upon joining, represent variable interests in variable interest entities. MPA is the primary beneficiary of Wholesale One and Residential Investor One as it has the power to direct the activities that most significantly impact the economic performance of Wholesale One and Residential Investor One and the right to receive benefits from Wholesale One and Residential Investor One. As a result, Wholesale One and Residential Investor One are presented in the accompanying condensed consolidated financial statements on a consolidated basis with the interests of the members reflected as non-controlling interests. As of September 30, 2015, Wholesale One and Residential Investor One each had less than $0.1 million in total assets and less than $0.1 million in total liabilities. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in our Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, which contains a summary of our significant accounting policies. Certain footnote detail in the Form 10-K is omitted from the information included herein.
Fair Value Measurements	Fair Value Measurements Fair value is defined as an exit price, representing the amount that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three-tier hierarchy for inputs used in measuring fair value, which prioritizes the inputs used in the methodologies of measuring fair value for assets and liabilities, is as follows: Level 1 — Quoted prices in active markets for identical assets and liabilities Level 2 — Observable inputs other than quoted prices included in Level 1 Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of assets or liabilities. Financial assets and financial liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Our assessment of the significance of a particular input to the fair value measurements requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.
Future Adoption of New Accounting Pronouncement	Future Adoption of New Accounting Pronouncements In May 2014, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principle of the new standard is 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. In August 2015, in response to stakeholders’ requests to defer the effective date of ASU 2014-09 and in consideration of feedback received through extensive outreach with preparers, practitioners and users of financial statements, the FASB deferred the effective date for all entities by one year. This new standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted, although not prior to annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact this new guidance may have on its results of operations and financial position. In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. This standard addresses the consolidation of certain legal entities relative to current requirements under GAAP of a reporting entity to consolidate another legal entity in situations in which the reporting entity’s contractual rights do not give it the ability to act primarily on its own behalf, the reporting entity does not hold a majority of the legal entity’s voting rights or the reporting entity is not exposed to a majority of the legal entity’s economic benefits or obligations. This standard will be effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the standard in an interim period, any adjustments should be reflected as of the beginning of the year that includes that interim period. The Company is currently evaluating the impact this new guidance may have on its results of operations and financial position. In April 2015, FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This standard changes the presentation of debt issuance costs in financial statements. Under the ASU, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. This standard will be effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of this standard to have a material impact on its results of operations or financial position. In September 2015, FASB issued ASU No. 2015-16, Business Combination (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This standard requires that adjustments to provisional amounts that are identified during measurement period are recognized in the reporting period in which the adjustment amounts are determined rather than recognizing the adjustments retrospectively. The standard also requires that the acquirer records, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. This standard will be effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of this standard to have a material impact on its results of operations or financial position.
