Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	1. Business Winthrop Realty Liquidating Trust (the “Liquidating Trust”) was organized on July 28, 2016 as a liquidating trust pursuant to a plan of liquidation of Winthrop Realty Trust, (“Winthrop”). Winthrop, which began operations in 1961 under the name First Union Real Estate Equity and Mortgage Investments and changed its name to Winthrop Realty Trust in 2005, was a real estate investment trust formed under the laws of the State of Ohio. Winthrop conducted its business through its wholly owned operating partnership, WRT Realty L.P., a Delaware limited partnership, (the “Operating Partnership”). From January 1, 2004 through August 5, 2016, Winthrop was externally managed by FUR Advisors LLC, (“FUR Advisors” or the “Advisor”). Since August 5, 2016, FUR Advisors has continued to manage the Liquidating Trust’s assets. The Advisor is majority owned by Winthrop’s former executive officers and senior management, including Michael L. Ashner and Carolyn Tiffany, two of the Liquidating Trust’s trustees. Winthrop’s primary business was owning real property and real estate related assets. On April 28, 2014 Winthrop’s Board of Trustees adopted a plan of liquidation. The plan, which provided for an orderly liquidation of Winthrop’s assets, was approved by holders of a majority of Winthrop’s common shares of beneficial interest (“Common Shares”) at a special meeting of shareholders on August 5, 2014. Under the plan of liquidation, if all of the assets of Winthrop were not disposed of by August 5, 2016, the then remaining assets and liabilities of Winthrop would be assigned to a liquidating trust. On August 5, 2016, in accordance with Winthrop’s plan of liquidation, Winthrop transferred the then remaining assets and liabilities, including its ownership interests in the Operating Partnership, to the Liquidating Trust. The Liquidating Trust is governed by a Liquidating Trust Agreement by and among Winthrop and Michael L. Ashner, Howard Goldberg and Carolyn Tiffany, as trustees. Upon the transfer of the assets and liabilities to the Liquidating Trust, each Common Share on August 5, 2016, was automatically converted into one unit of beneficial interest in the Liquidating Trust, (“Unit”), and each holder of Common Shares become a beneficiary of the Liquidating Trust, (“Beneficiaries”). On October 3, 2016, Winthrop filed a Form 15 with the Securities and Exchange Commission (the “SEC”) to terminate the registration of the Common Shares under the Securities Exchange Act of 1934, as amended, and Winthrop ceased filing reports under that act. The Liquidating Trust will only file with the SEC annual reports on Form 10-K 8-K. The sole purpose of the Liquidating Trust is to wind up the affairs of Winthrop by liquidating its remaining assets, satisfying the assumed liabilities, paying all costs and expenses of the Liquidating Trust and distributing the remaining proceeds to the Beneficiaries. The Liquidating Trust has no objective to continue or engage in the conduct of a trade or business, expect as necessary for the orderly liquidation of the remaining assets.

Plan of Liquidation	2. Plan of Liquidation Subsequent to August 5, 2014, Winthrop was not, and under the Liquidating Trust Agreement the Liquidating Trust is not, permitted to make any new investments other than protective acquisitions or advances with respect to its existing assets. Winthrop was, and the Liquidating Trust is, permitted to satisfy any existing contractual obligations including any capital call requirements and acquisitions or dispositions pursuant to buy-sell The Liquidating Trust Agreement enables the Liquidating Trust to sell any and all of its assets without further approval of the unitholders and provides that liquidating distributions be made to the unitholders as determined by the trustees. Pursuant to applicable real estate investment trust (“REIT”) rules, in order to be able to deduct liquidating distributions as dividends, Winthrop was required to complete the disposition of its assets by August 5, 2016, two years after the date the plan of liquidation was adopted by shareholders. Winthrop satisfied this requirement by distributing its unsold assets into the Liquidating Trust on August 5, 2016. In connection with the transfer of assets to, and the assumption of liabilities by, the Liquidating Trust, the stock transfer books of Winthrop were closed as of the close of business on August 1, 2016. All of the outstanding Common Shares were automatically deemed cancelled, and the rights of the Beneficiaries in their Units are not represented by any form of certificate or other instrument. Holders of Common Shares were not required to take any action to receive their Units. On the date of the transfer, the economic value of each Unit was equivalent to the economic value of a Common Share. Holders of the Units should note that unlike Common Shares, which were freely transferable, Units in the Liquidating Trust are generally not transferable except by will, intestate succession or operation of law. Therefore, the Beneficiaries have no ability to realize any value from these interests except from distributions made by the Liquidating Trust, the timing of which will be solely at the discretion of the Liquidating Trust’s trustees. The Liquidating Trust will terminate upon the earlier of (i) the distribution of all of the remaining assets of the Liquidating Trust in accordance with the terms of the Liquidating Trust Agreement, or (ii) August 5, 2019. The Liquidating Trust may be extended beyond August 5, 2019 if the trustees of the Liquidating Trust determine that an extension is reasonably necessary to fulfill the purpose of the Liquidating Trust. Although no assurances can be given, it is anticipated that the plan of liquidation will be completed by December 31, 2018. The dissolution process and the amount and timing of distributions to unitholders involves risks and uncertainties. Accordingly, it is not possible to predict the timing or aggregate amount which will ultimately be distributed to unitholders and no assurance can be given that the distributions will equal or exceed the estimate of net assets presented in the Consolidated Statements of Net Assets.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements have been presented on a comparative basis. For periods prior to August 5, 2016, the entity is referred to as Winthrop Realty Trust, and from and after August 5, 2016 the entity is referred to as Winthrop Realty Liquidating Trust (see Note 1). The same basis of accounting have been used to prepare the financial statements for both Winthrop and the Liquidating Trust. The accompanying consolidated financial statements represent the consolidated results of Winthrop and the Liquidating Trust, their wholly-owned taxable REIT subsidiary, WRT-TRS As a result of the approval of the plan of liquidation by the shareholders, Winthrop and the Liquidating Trust have adopted the liquidation basis of accounting as of August 1, 2014 and for the periods subsequent to August 1, 2014 in accordance with accounting principles generally accepted in the United States (“GAAP”). Accordingly, on August 1, 2014 assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash that Winthrop or the Liquidating Trust will collect on disposal of assets as it carries out its plan of liquidation. The liquidation value of Winthrop’s and the Liquidating Trust’s operating properties and loan assets are presented on an undiscounted basis. Estimated costs to dispose of assets have been presented separately from the related assets. Liabilities are carried at their contractual amounts due or estimated settlement amounts. Winthrop and the Liquidating Trust accrue costs and income that they expect to incur and earn through the end of liquidation to the extent it has a reasonable basis for estimation. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets. Actual costs and income may differ from amounts reflected in the financial statements because of inherent uncertainty in estimating future events. These differences may be material. See Note 4 for further discussion. Actual costs incurred but unpaid as of December 31, 2016 and 2015 are included in accounts payable, accrued liabilities and other liabilities on the Consolidated Statements of Net Assets. In liquidation, the presentation for joint ventures historically consolidated under going concern accounting is determined based on Winthrop’s and the Liquidating Trust’s planned exit strategy. Those ventures where Winthrop or the Liquidating Trust intends to sell the property are presented on a gross basis with a payable to the non-controlling non-controlling Net assets in liquidation represents the estimated liquidation value available to holders of Units upon liquidation. Due to the uncertainty in the timing of the anticipated sale dates and the estimated cash flows, actual operating results and sale proceeds may differ materially from the amounts estimated. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions in determining the values of assets and liabilities, disclosing contingent assets and liabilities at the date of the consolidated financial statements and the amounts of revenue and expenses during the reporting period. Under liquidation accounting, the Liquidating Trust is required to estimate all costs and income that it expects to incur and earn through the end of liquidation including the estimated amount of cash it will collect on disposal of its assets and estimated costs incurred to dispose of assets. All of the estimates and evaluations are susceptible to change and actual results could differ materially from the estimates and evaluations. Investments in Real Estate As of August 1, 2014 the investments in real estate were adjusted to their estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash that the Liquidating Trust will collect on disposal of its assets, inclusive of any residual value attributable to lease intangibles, as it carries out its plan of liquidation. The liquidation value of the Liquidating Trust’s investments in real estate are presented on an undiscounted basis and investments in real estate are no longer depreciated. Estimated costs to dispose of these investments are presented separately from the related assets. Subsequent to August 1, 2014, all changes in the estimated liquidation value of the investments in real estate are reflected as a change to the Liquidating Trust’s net assets in liquidation. Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments purchased with original maturities of three months or less. The Liquidating Trust maintains cash and cash equivalents in financial institutions in excess of insured limits, but believes this risk is mitigated by only investing in or through major financial institutions. Restricted Cash Restricted cash in escrow accounts include cash reserves for tenant improvements, leasing commissions, real estate taxes and other expenses pursuant to the loan agreements. In addition, certain security deposit accounts are classified as restricted cash. Loans Receivable Under liquidation accounting, the Liquidating Trust carries its loans receivable at their estimated net realizable value, or liquidation value, which represents the estimated amount of principal payments the Liquidating Trust expects to receive over the holding period of the loan. The liquidation value of the Liquidating Trust’s loans receivable are presented on an undiscounted basis. Interest payments that the Liquidating Trust expects to receive on its loans receivable over the estimated holding period of the loan are accrued and are classified as part of liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets. As interest is earned, it is reclassified and included in loans receivable on the Consolidated Statements of Net Assets. The Liquidating Trust evaluates the collectability of the interest and principal of each of its loans. Any changes in collectability will be reflected as a change to the Liquidating Trust’s net assets in liquidation. Accounts Receivable In accordance with liquidation accounting, as of August 1, 2014, accounts receivable were adjusted to their net realizable value. The Liquidating Trust continues to review its accounts receivable monthly. Past due balances are reviewed individually for collectability. Any changes in the collectability of the receivables are reflected in the net realizable value of the accounts receivable. Accrued rental income is not contemplated under liquidation accounting. The Liquidating Trust accrues rental revenue based on contractual amounts expected to be collected during liquidation. Equity Investments The Liquidating Trust accounts for its investments in entities in which it has the ability to significantly influence, but does not have a controlling interest, by using the equity method of accounting. Factors that are considered in determining whether or not the Liquidating Trust exercises control include (i) the right to remove the general partner or managing member in situations where the Liquidating Trust is not the general partner or managing member, and (ii) substantive participating rights of equity holders in significant business decisions including dispositions and acquisitions of assets, financing, operations and capital budgets, and other contractual rights. Subsequent to the adoption of liquidation accounting, equity investments are recorded at their net realizable value. The Liquidating Trust evaluates the net realizable value of its equity investments at each reporting period. Any changes in net realizable value will be reflected as a change to the Liquidating Trust’s net assets in liquidation. Deferred Financing Costs Prior to the adoption of the plan of liquidation, direct financing costs were deferred and amortized over the terms of the related agreements as a component of interest expense. As deferred financing costs will not be converted to cash or other consideration, these have been valued at $0 as of August 1, 2014 in accordance with liquidation accounting. Financial Instruments Financial instruments held by the Liquidating Trust include cash and cash equivalents, restricted cash, loan securities, loans receivable, interest rate hedge agreements, accounts receivable, accounts payable and long term debt. Under liquidation accounting, all financial instruments are recorded at their net realizable value. Derivative Financial Instruments The Liquidating Trust has exposure to fluctuations in market interest rates. The Liquidating Trust utilizes its interest rate cap agreements to manage interest rate risk and does not intend to enter into derivative transactions for speculative or trading purposes. As these instruments will not be converted into cash or other consideration, derivative financial instruments were valued at $0 as of August 1, 2014 in accordance with liquidation accounting. These financial instruments are still in place as of December 31, 2016. Revenue Recognition Pursuant to the terms of the lease agreements with respect to net lease properties, the tenant at each property is required to pay all costs associated with the property including property taxes, ground rent, maintenance costs and insurance. These costs are not reflected in the consolidated financial statements. To the extent any of these tenants defaults under its lease and fails to pay such costs, the Liquidating Trust will record a liability for such obligations. Tenant leases that are not net leases generally provide for (i) billings of fixed minimum rental and (ii) billings of certain operating costs. Winthrop accrued the recovery of operating costs based on actual costs incurred. Under liquidation accounting, the Liquidating Trust has accrued all income that it expects to earn through the end of liquidation to the extent it has a reasonable basis for estimation. These amounts are classified in liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets. Income Taxes Winthrop operated in a manner which qualified it as a REIT for tax purposes. In order to qualify as a REIT, Winthrop was generally required each year to distribute to its shareholders at least 90% of its taxable income (excluding any net capital gains). There is also a separate requirement to distribute net capital gains or pay a corporate level tax. Winthrop complied with the foregoing minimum dividend requirements through the date of transfer of its remaining assets and liabilities to the Liquidating Trust. Given the organizational structure, the Liquidating Trust will be treated as a partnership for federal and state income tax purposes. Accordingly, no provision or benefit for income taxes is made in the consolidated financial statements as taxable income or loss passes through to, and is the responsibility of, the unitholders. Winthrop and the Liquidating Trust reviewed its tax positions under accounting guidance which require that a tax position may only be recognized in the financial statements if it is more likely than not that the tax position will prevail if challenged by taxing authorities. Winthrop and the Liquidating Trust believe it is more likely than not that its tax positions will be sustained in any tax examination. Winthrop and the Liquidating Trust had no deferred tax assets or deferred tax liabilities associated with any such uncertain tax positions for the operations of any entity included in the Consolidated Financial Statements. The only provision for federal income taxes relates to the TRS and is included in the liability for estimated costs in excess of estimated receipts during liquidation. Winthrop’s and the Liquidating Trust’s tax returns are subject to audit by taxing authorities. The tax years 2013 – 2016 remain open to examination by major taxing jurisdictions to which Winthrop was subject. The Liquidating Trust’s initial tax return will be filed in 2017.

Liability for Estimated Costs in Excess of Estimated Receipts During Liquidation	4. Liability for Estimated Costs in Excess of Estimated Receipts During Liquidation The liquidation basis of accounting requires the Liquidating Trust to estimate net cash flows from operations and to accrue all costs associated with implementing and completing the plan of liquidation. The Liquidating Trust currently estimates that it will have costs in excess of estimated receipts during the liquidation. These amounts can vary significantly due to, among other things, the timing and estimates for executing and renewing leases, estimates of tenant improvement costs, the timing of property sales, direct costs incurred to complete the sales, the timing and amounts associated with discharging known and contingent liabilities and the costs associated with the winding up of operations. These costs are estimated and are anticipated to be paid out over the liquidation period. As of December 31, 2016 and 2015, the Liquidating Trust and Winthrop, respectively, had accrued the following revenues and expenses expected to be earned or incurred during liquidation (in thousands): December 31, 2016 December 31, 2015 Rents and reimbursements $ 14,369 $ 29,636 Interest and dividends 1,036 3,646 Property operating expenses (4,803 ) (10,756 ) Interest expense (4,911 ) (7,546 ) General and administrative expenses (24,866 ) (34,264 ) Capital expenditures (1,159 ) (4,027 ) Sales costs (2,852 ) (5,986 ) Liability for estimated costs in excess of estimated receipts during liquidation $ (23,186 ) $ (29,297 ) The change in the liability for estimated costs in excess of estimated receipts during liquidation as of December 31, 2016 is as follows (in thousands): December 31, 2015 Cash Payments Remeasurement Consolidation (1) December 31, 2016 Assets: Estimated net inflows from investments in real estate, loans receivable and secured financing receivable $ 10,523 $ (4,847 ) $ (978 ) $ (1,306 ) $ 3,392 Liabilities: Sales costs (5,986 ) 3,215 363 (443 ) (2,851 ) Corporate expenditures (33,834 ) 7,351 2,756 — (23,727 ) (39,820 ) 10,566 3,119 (443 ) (26,578 ) Total liability for estimated costs in excess of estimated receipts during liquidation $ (29,297 ) $ 5,719 $ 2,141 $ (1,749 ) $ (23,186 ) (1) Due to a change in exit strategy, the venture that owns property in Oklahoma City, Oklahoma is no longer accounted for using the equity method.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Net Assets in Liquidation	5. Net Assets in Liquidation Net assets in liquidation decreased by $188,469,000 during the year ended December 31, 2016. The primary reason for the decline in net assets was due to liquidating distributions to holders of Common Shares of $173,019,000, and a $21,900,000 net decrease in the liquidation value of investments in real estate. These decreases were partially offset by a $3,142,000 net increase in the liquidation value of equity investments, a $2,756,000 decrease in estimated corporate expenditures resulting primarily from decreases in estimated fees payable to FUR Advisors as a result of decreases in liquidation values of certain investments, and a $1,067,000 decrease in the liability for non-controlling Net assets in liquidation decreased by $78,308,000 during the year ended December 31, 2015. The primary reason for the decline in net assets was due to liquidating distributions to holders of Common Shares of $81,956,000 and a $3,363,000 net decrease in the value of investments in real estate, a $1,723,000 increase in estimated corporate expenditures resulting primarily from increases in estimated fees payable to FUR Advisors as a result of increases in liquidation values of certain investments and a $918,000 decrease in the value of the Winthrop’s loan securities. These decreases were partially offset by a $10,343,000 net increase in the liquidation value of equity investments and a $1,445,000 decrease in the liability for non-controlling There were 36,425,084 Units outstanding at December 31, 2016. There were 36,425,084 Common Shares outstanding at December 31, 2015. The net assets in liquidation at December 31, 2016 would result in liquidating distributions of approximately $9.00 per Unit. The net assets in liquidation as of December 31, 2016 and 2015 of $327,927,000 and $516,396,000 respectively, plus the cumulative liquidating distributions to holders of Units or Common Shares through December 31, 2016 and 2015 of $336,934,000 ($9.25 per Common Share/Unit) and $163,915,000 ($4.50 per Common Share/Unit), respectively, would result in cumulative liquidating distributions to holders of Units/Common Shares of $18.25 and $18.68 per Unit or Common Share as of December 31, 2016 and 2015, respectively. This estimate of liquidating distributions includes projections of costs and expenses to be incurred during the period required to complete the plan of liquidation. There is inherent uncertainty with these projections, and they could change materially based on the timing of sales, the performance of underlying assets and any changes in the underlying assumptions of the projected cash flows.

(2) The loan has an interest rate floor of 6% and an interest rate ceiling of 8%. (3) The loan was repaid in full during 2016. (4) The senior lien holder foreclosed on the property on June 2, 2016. (5) The loan was fully satisfied for a discounted payoff amount of $100 in October 2016. The carrying amount of loans receivable at December 31, 2016 and 2015 represents the estimated amount expected to be collected on disposition of the loans and includes accrued interest of $0 and $28,000, respectively. The weighted average coupon as calculated on the par value of loans receivable was 6.00% and 7.97% at December 31, 2016 and 2015, respectively, and the weighted average yield to maturity as calculated on the carrying value of loans receivable was 6.00% and 13.54% at December 31, 2016 and 2015, respectively. At December 31, 2016 and 2015, none of Winthrop’s or the Liquidating Trust’s loans receivable were directly financed. Loan Receivable Activity Activity related to loans receivable is as follows (in thousands): Year Ended Year Ended December 31, 2016 December 31, 2015 Balance at beginning of year $ 5,280 $ 24,005 Purchase and advances 9,035 — Interest received, net (28 ) (190 ) Repayments/sale proceeds (5,987 ) (18,535 ) Change in liquidation value 100 — Balance at end of year $ 8,400 $ 5,280 Credit Quality of Loans Receivable Under liquidation accounting, the Liquidating Trust carries its loans receivable at the estimated amount of principal payments it expects to receive over the holding period of the loan. The Liquidating Trust utilizes a grading system to assess the collectability of its loan portfolio. Grading categories included debt yield, debt service coverage ratio, length of loan, property type, loan type, and other more subjective variables that included property or collateral location, market conditions, industry conditions, and sponsor’s financial stability. Management reviewed each category and assigned an overall numeric grade for each loan to determine the loan’s risk of loss and to provide a determination as to whether an individual loan required an adjustment to the recorded liquidation value. All loans with a positive score did not require a loan loss allowance. Any loan graded with a neutral score or “zero” was subject to further review of the collectability of the interest and principal based on current conditions and qualitative factors. Any change in the credit quality of the loan receivable that changes the Liquidating Trust’s estimate of the amount it expects to collect will be recorded as a change to the liquidation value of its loans receivable. The table below summarizes the Liquidating Trust’s loans receivable by internal credit rating at December 31, 2016 and 2015 (in thousands, except for number of loans): December 31, 2016 December 31, 2015 Liquidation Liquidation Number of Value of Loans Number of Value of Loans Internal Credit Quality Loans Receivable Loans Receivable Greater than zero 1 $ 8,400 2 $ 5,280 Equal to zero — — 1 — Less than zero — — 1 — 1 $ 8,400 4 $ 5,280 Secured Financing Receivable In August 2013 Winthrop closed on an agreement to acquire its venture partner’s (“Elad”) 50% interest in the mezzanine lender with respect to the One South State Street, Chicago, Illinois property (“Lender LP”) for $30,000,000. In connection with the transaction, Winthrop entered into an option agreement with Elad granting Elad the right, but not obligation, to repurchase the interest in the venture. The option agreement provided Elad, as the transferor, the option to unilaterally cause the return of the asset at the earlier of two years from and after August 21, 2013 or an event of default on Lender LP’s mezzanine debt. As such, Elad was able to retain control of its interest in Lender LP for financial reporting purposes as the exercise of the option was unconditional other than for the passage of time. As a result, for financial reporting purposes, the transfer of the financial asset was accounted for as a secured financing rather than an acquisition. The $30,000,000 acquisition price was recorded as a secured financing receivable. On April 27, 2016 Winthrop sold its interest in the secured financing receivable. See Note 6 – “Investment and Disposition Activities” for further details on the sale.

The Liquidating Trust’s venture which owns the property located at 450 W 14 th The Liquidating Trust is involved from time to time in litigation on various matters, including disputes with tenants and disputes arising out of agreements to purchase or sell properties. Given the nature of the Liquidating Trust’s business activities, these lawsuits are considered routine to the conduct of its business. The result of any particular lawsuit cannot be predicted because of the very nature of litigation, the litigation process and its adversarial nature, and the jury system. The Liquidating Trust does not expect that the liabilities, if any, that may ultimately result from such legal actions will have a material adverse effect on its financial condition or results of operations.

Related Party Transactions [Abstract]
Related-Party Transactions	13. Related-Party Transactions The activities of the Liquidating Trust are administered by FUR Advisors pursuant to the terms of the Advisory Agreement between Winthrop and FUR Advisors. FUR Advisors is majority owned by Winthrop’s former executive officers and senior management, including two of the Liquidating Trust’s trustees. Pursuant to the terms of the Advisory Agreement, FUR Advisors is responsible for providing asset management services to the Liquidating Trust and coordinating with the Liquidating Trust’s unitholder transfer agent and property managers. FUR Advisors is entitled to receive a base management fee and a termination fee and/or an incentive fee in accordance with the terms of the Advisory Agreement. In addition, FUR Advisors or its affiliate is entitled to receive property and construction management fees subject to the approval of the trustees. Base Asset Management Fee – In connection with the adoption of the plan of liquidation, the Liquidating Trust accrues costs it expects to incur through the end of the liquidation. In this regard, at December 31, 2016 the Liquidating Trust has accrued, based on its estimates of the timing and amounts of liquidating distributions to be paid to holders of Units, base management fees of $4,914,000 exclusive of the $880,000 included in related party fees payable. This amount is included in liabilities for estimated costs in excess of estimated receipts during liquidation. Actual fees incurred may differ significantly from these estimates due to inherent uncertainty in estimating future events. Incentive Fee / Termination Fee - With respect to the termination fee, it is only payable if there is (i) a termination of the Advisory Agreement for any reason other than for cause (as defined) by the Liquidating Trust or with cause by the Advisor, or (ii) a disposition of all or substantially all of the Liquidating Trust’s assets. The termination fee, if payable, is equal to the lesser of (i) the base management fee paid to the Advisor for the prior twelve month period or (ii) either (x) in the case of a termination of the Advisory Agreement, 20% of the positive difference, if any between (A) the appraised net asset value of the Liquidating Trust’s assets at the date of termination and (B) the threshold amount less $104,980,000, or (y) in the case of a disposition, 20% of any liquidating distributions paid on account of the Units at such time as the threshold amount is reduced to $104,980,000, which, based on current estimates, will be achieved at such time as additional liquidating distributions of approximately $4.65 per Unit in excess of the Growth Factor have been paid. For example, if all of the Liquidating Trust’s assets were sold and the proceeds therefrom were distributed to holders of Units at January 1, 2017, the termination fee would only have been payable if additional liquidating distributions of approximately $4.65 per Unit had been paid, and then only until the total termination fee paid would have equaled $9,496,000 (the base management fee for the twelve months prior to the approved plan of liquidation), which amount would be achieved when total additional liquidating distributions paid per Unit equaled approximately $5.69. At December 31, 2016 it is estimated that the Advisor will be entitled to a termination fee of $9,496,000 upon disposition of the remaining assets. This amount has been accrued and is included in liabilities for estimated costs in excess of estimated receipts during liquidation. Property Management and Construction Management - The following table sets forth the fees and reimbursements paid or accrued by Winthrop and the Liquidating Trust for the years ended December 31, 2016 and 2015 to FUR Advisors and Winthrop Management (in thousands): For the Years Ended December 31, 2016 2015 Base Asset Management Fee (1) $ 4,575 $ 6,367 Property Management Fee 633 974 Construction Management Fee 3 130 $ 5,211 $ 7,471 (1) Includes fees on third party contributions of $10 and $27 for the years ended December 31, 2016 and 2015, respectively.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been presented on a comparative basis. For periods prior to August 5, 2016, the entity is referred to as Winthrop Realty Trust, and from and after August 5, 2016 the entity is referred to as Winthrop Realty Liquidating Trust (see Note 1). The same basis of accounting have been used to prepare the financial statements for both Winthrop and the Liquidating Trust. The accompanying consolidated financial statements represent the consolidated results of Winthrop and the Liquidating Trust, their wholly-owned taxable REIT subsidiary, WRT-TRS As a result of the approval of the plan of liquidation by the shareholders, Winthrop and the Liquidating Trust have adopted the liquidation basis of accounting as of August 1, 2014 and for the periods subsequent to August 1, 2014 in accordance with accounting principles generally accepted in the United States (“GAAP”). Accordingly, on August 1, 2014 assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash that Winthrop or the Liquidating Trust will collect on disposal of assets as it carries out its plan of liquidation. The liquidation value of Winthrop’s and the Liquidating Trust’s operating properties and loan assets are presented on an undiscounted basis. Estimated costs to dispose of assets have been presented separately from the related assets. Liabilities are carried at their contractual amounts due or estimated settlement amounts. Winthrop and the Liquidating Trust accrue costs and income that they expect to incur and earn through the end of liquidation to the extent it has a reasonable basis for estimation. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets. Actual costs and income may differ from amounts reflected in the financial statements because of inherent uncertainty in estimating future events. These differences may be material. See Note 4 for further discussion. Actual costs incurred but unpaid as of December 31, 2016 and 2015 are included in accounts payable, accrued liabilities and other liabilities on the Consolidated Statements of Net Assets. In liquidation, the presentation for joint ventures historically consolidated under going concern accounting is determined based on Winthrop’s and the Liquidating Trust’s planned exit strategy. Those ventures where Winthrop or the Liquidating Trust intends to sell the property are presented on a gross basis with a payable to the non-controlling non-controlling Net assets in liquidation represents the estimated liquidation value available to holders of Units upon liquidation. Due to the uncertainty in the timing of the anticipated sale dates and the estimated cash flows, actual operating results and sale proceeds may differ materially from the amounts estimated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions in determining the values of assets and liabilities, disclosing contingent assets and liabilities at the date of the consolidated financial statements and the amounts of revenue and expenses during the reporting period. Under liquidation accounting, the Liquidating Trust is required to estimate all costs and income that it expects to incur and earn through the end of liquidation including the estimated amount of cash it will collect on disposal of its assets and estimated costs incurred to dispose of assets. All of the estimates and evaluations are susceptible to change and actual results could differ materially from the estimates and evaluations.
Investments in Real Estate	Investments in Real Estate As of August 1, 2014 the investments in real estate were adjusted to their estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash that the Liquidating Trust will collect on disposal of its assets, inclusive of any residual value attributable to lease intangibles, as it carries out its plan of liquidation. The liquidation value of the Liquidating Trust’s investments in real estate are presented on an undiscounted basis and investments in real estate are no longer depreciated. Estimated costs to dispose of these investments are presented separately from the related assets. Subsequent to August 1, 2014, all changes in the estimated liquidation value of the investments in real estate are reflected as a change to the Liquidating Trust’s net assets in liquidation.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments purchased with original maturities of three months or less. The Liquidating Trust maintains cash and cash equivalents in financial institutions in excess of insured limits, but believes this risk is mitigated by only investing in or through major financial institutions.
Restricted Cash	Restricted Cash Restricted cash in escrow accounts include cash reserves for tenant improvements, leasing commissions, real estate taxes and other expenses pursuant to the loan agreements. In addition, certain security deposit accounts are classified as restricted cash.
Loans Receivable	Loans Receivable Under liquidation accounting, the Liquidating Trust carries its loans receivable at their estimated net realizable value, or liquidation value, which represents the estimated amount of principal payments the Liquidating Trust expects to receive over the holding period of the loan. The liquidation value of the Liquidating Trust’s loans receivable are presented on an undiscounted basis. Interest payments that the Liquidating Trust expects to receive on its loans receivable over the estimated holding period of the loan are accrued and are classified as part of liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets. As interest is earned, it is reclassified and included in loans receivable on the Consolidated Statements of Net Assets. The Liquidating Trust evaluates the collectability of the interest and principal of each of its loans. Any changes in collectability will be reflected as a change to the Liquidating Trust’s net assets in liquidation.
Accounts Receivable	Accounts Receivable In accordance with liquidation accounting, as of August 1, 2014, accounts receivable were adjusted to their net realizable value. The Liquidating Trust continues to review its accounts receivable monthly. Past due balances are reviewed individually for collectability. Any changes in the collectability of the receivables are reflected in the net realizable value of the accounts receivable. Accrued rental income is not contemplated under liquidation accounting. The Liquidating Trust accrues rental revenue based on contractual amounts expected to be collected during liquidation.
Equity Investments	Equity Investments The Liquidating Trust accounts for its investments in entities in which it has the ability to significantly influence, but does not have a controlling interest, by using the equity method of accounting. Factors that are considered in determining whether or not the Liquidating Trust exercises control include (i) the right to remove the general partner or managing member in situations where the Liquidating Trust is not the general partner or managing member, and (ii) substantive participating rights of equity holders in significant business decisions including dispositions and acquisitions of assets, financing, operations and capital budgets, and other contractual rights. Subsequent to the adoption of liquidation accounting, equity investments are recorded at their net realizable value. The Liquidating Trust evaluates the net realizable value of its equity investments at each reporting period. Any changes in net realizable value will be reflected as a change to the Liquidating Trust’s net assets in liquidation.
Deferred Financing Costs	Deferred Financing Costs Prior to the adoption of the plan of liquidation, direct financing costs were deferred and amortized over the terms of the related agreements as a component of interest expense. As deferred financing costs will not be converted to cash or other consideration, these have been valued at $0 as of August 1, 2014 in accordance with liquidation accounting.
Financial Instruments	Financial Instruments Financial instruments held by the Liquidating Trust include cash and cash equivalents, restricted cash, loan securities, loans receivable, interest rate hedge agreements, accounts receivable, accounts payable and long term debt. Under liquidation accounting, all financial instruments are recorded at their net realizable value.
Derivative Financial Instruments	Derivative Financial Instruments The Liquidating Trust has exposure to fluctuations in market interest rates. The Liquidating Trust utilizes its interest rate cap agreements to manage interest rate risk and does not intend to enter into derivative transactions for speculative or trading purposes. As these instruments will not be converted into cash or other consideration, derivative financial instruments were valued at $0 as of August 1, 2014 in accordance with liquidation accounting. These financial instruments are still in place as of December 31, 2016.
Revenue Recognition	Revenue Recognition Pursuant to the terms of the lease agreements with respect to net lease properties, the tenant at each property is required to pay all costs associated with the property including property taxes, ground rent, maintenance costs and insurance. These costs are not reflected in the consolidated financial statements. To the extent any of these tenants defaults under its lease and fails to pay such costs, the Liquidating Trust will record a liability for such obligations. Tenant leases that are not net leases generally provide for (i) billings of fixed minimum rental and (ii) billings of certain operating costs. Winthrop accrued the recovery of operating costs based on actual costs incurred. Under liquidation accounting, the Liquidating Trust has accrued all income that it expects to earn through the end of liquidation to the extent it has a reasonable basis for estimation. These amounts are classified in liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statements of Net Assets.
Income Taxes	Income Taxes Winthrop operated in a manner which qualified it as a REIT for tax purposes. In order to qualify as a REIT, Winthrop was generally required each year to distribute to its shareholders at least 90% of its taxable income (excluding any net capital gains). There is also a separate requirement to distribute net capital gains or pay a corporate level tax. Winthrop complied with the foregoing minimum dividend requirements through the date of transfer of its remaining assets and liabilities to the Liquidating Trust. Given the organizational structure, the Liquidating Trust will be treated as a partnership for federal and state income tax purposes. Accordingly, no provision or benefit for income taxes is made in the consolidated financial statements as taxable income or loss passes through to, and is the responsibility of, the unitholders. Winthrop and the Liquidating Trust reviewed its tax positions under accounting guidance which require that a tax position may only be recognized in the financial statements if it is more likely than not that the tax position will prevail if challenged by taxing authorities. Winthrop and the Liquidating Trust believe it is more likely than not that its tax positions will be sustained in any tax examination. Winthrop and the Liquidating Trust had no deferred tax assets or deferred tax liabilities associated with any such uncertain tax positions for the operations of any entity included in the Consolidated Financial Statements. The only provision for federal income taxes relates to the TRS and is included in the liability for estimated costs in excess of estimated receipts during liquidation. Winthrop’s and the Liquidating Trust’s tax returns are subject to audit by taxing authorities. The tax years 2013 – 2016 remain open to examination by major taxing jurisdictions to which Winthrop was subject. The Liquidating Trust’s initial tax return will be filed in 2017.
