Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. ORGA NIZATION PJT Partners Inc. and its consolidated subsidiaries (the “Company” or “PJT Partners”) offer a unique portfolio of advisory services designed to help clients achieve their strategic objectives. On October 1, 2015, Blackstone Inc. (“Blackstone” or the “former Parent”) distributed on a pro rata basis to its common unitholders all of the issued and outstanding shares of Class A common stock of PJT Partners Inc. held by it. This pro rata distribution is referred to as the “Distribution.” The separation of the PJT Partners business from Blackstone and related transactions, including the Distribution, the internal reorganization that preceded the Distribution and the acquisition by PJT Partners of PJT Capital LP (together with its general partner and their respective subsidiaries, “PJT Capital”) that occurred substantially concurrently with the Distribution, is referred to as the “spin-off.” PJT Partners Inc. is the sole general partner of PJT Partners Holdings LP. PJT Partners Inc. owns less than 100 % of the economic interest in PJT Partners Holdings LP, but has 100 % of the voting power and controls the management of PJT Partners Holdings LP. As of June 30, 2023 , the non-controlling interest of PJT Partners Holdings LP was 37.5 %. As the sole general partner of PJT Partners Holdings LP, PJT Partners Inc. operates and controls all of the business and affairs and consolidates the financial results of PJT Partners Holdings LP and its operating subsidiaries. The Company operates through the following subsidiaries: PJT Partners LP, PJT Partners (UK) Limited, PJT Partners (HK) Limited, PJT Partners Park Hill (Spain) A.V., S.A.U., PJT Partners (Germany) GmbH, PJT Partners (France) SAS and PJT Partners Japan K.K.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The Company prepared the accompanying condensed consolidated financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. The condensed consolidated financial statements, including these notes, are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting of only normal recurring items) so that the condensed consolidated financial statements are presented fairly and that estimates made in preparing its condensed consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Intercompany transactions have been eliminated for all periods presented. For a comprehensive disclosure of the Company’s significant accounting policies, see Note 2. “Summary of Significant Accounting Policies” in the “Notes to Consolidated Financial Statements” in “Part II. Item 8. Financial Statements and Supplementary Data” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 . Cash, Cash Equivalents and Investments Cash and Cash Equivalents include short-term highly liquid investments that are readily convertible to known amounts of cash and have original maturities of three months or less from the date of purchase. Cash and Cash Equivalents are maintained in U.S. and non-U.S. bank accounts and are held at seven financial institutions. Also included in Cash and Cash Equivalents are amounts held in bank accounts that are subject to advance notification to withdraw, which totaled $ 0.6 million as of each of June 30, 2023 and December 31, 2022. Treasury securities with original maturities greater than three months when purchased are classified as Investments in the Condensed Consolidated Statements of Financial Condition. Reclassifications Certain balances on the Condensed Consolidated Statements of Operations in the prior period have been reclassified to conform to their current presentation. For the three and six months ended June 30, 2022, this resulted in a reclassification of $ 1.3 million and $ 1.9 million, respectively, from Other Expenses to Travel and Related. This reclassification had no impact on net income or stockholders’ equity.

Such amounts relate to the Company’s performance obligations of providing advisory and placement services. The Company recognized revenue of $ 6.8 million and $ 10.4 million for the three and six months ended June 30, 2023 , respectively, and $ 21.0 million and $ 45.6 million for the three and six months ended June 30, 2022, respectively, related to performance obligations that were fully satisfied in prior periods, primarily due to constraints on variable consideration in prior periods being resolved. Such amounts related primarily to the provision of corporate and fund placement services. The majority of Fee Revenue recognized by the Company during the three and six months ended June 30, 2023 and 2022 was predominantly related to performance obligations that were partially satisfied in prior periods. Contract Balances There were no significant impairments related to contract balances during the three and six months ended June 30, 2023 and 2022. For the six months ended June 30, 2023 and 2022, $ 10.4 million and $ 9.9 million, respectively, of revenue was recognized that was included in the beginning balance of Deferred Revenue, primarily related to the Company’s performance obligation of standing ready to perform.

Contingencies Litigation From time to time, the Company may be named as a defendant in legal actions relating to transactions conducted in the ordinary course of business. Some of these matters may involve claims of substantial amounts. Although there can be no assurance of the outcome of such legal actions, in the opinion of management, after consultation with external counsel, the Company believes it is not probable and/or reasonably possible that any current legal proceedings or claims would individually or in the aggregate have a material adverse effect on the condensed consolidated financial statements of the Company. The Company is not currently able to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support such an assessment, including quantification of a damage demand from plaintiffs, discovery from other parties and investigation of factual allegations, rulings by courts on motions or appeals, analysis by experts or the status of any settlement negotiations. Guarantee The Company provides a guarantee to a lending institution for certain loans held by employees for investment in funds of its former Parent, which are secured by the underlying investments in those funds. The amount guaranteed was $ 2.6 million and $ 3.3 million as of June 30, 2023 and December 31, 2022, respectively. In connection with this guarantee, the Company currently expects any associated risk of loss to be insignificant. Indemnifications The Company has entered and may continue to enter into contracts that contain a variety of indemnification obligations. The Company’s maximum exposure under these arrangements is not known; however, the Company currently expects any associated risk of loss to be insignificant. In connection with these matters, the Company has incurred and may continue to incur legal expenses, which are expensed as incurred. Transactions and Agreements with Blackstone Employee Matters Agreement The Company is required to reimburse Blackstone for the value of forfeited unvested equity awards granted to former Blackstone employees that transitioned to PJT Partners in connection with the spin-off. Such reimbursement is recorded in Accounts Payable, Accrued Expenses and Other Liabilities with an offset to Equity in the Condensed Consolidated Statements of Financial Condition. The accrual for these forfeitures was $ 0.9 million as of June 30, 2023 and December 31, 2022.

Segment Reporting [Abstract]
Business Information	15. BUSINESS INFORMATION The Company’s activities providing advisory and placement services constitute a single reportable segment. An operating segment is a component of an entity that conducts business and incurs revenues and expenses for which discrete financial information is available that is reviewed by the chief operating decision maker in assessing performance and making resource allocation decisions. The Company has a single operating segment and therefore a single reportable segment. The Company is organized as one operating segment in order to maximize the value of advice to clients by drawing upon the diversified expertise and broad relationships of senior professionals across the Company. The chief operating decision maker assesses performance and allocates resources based on broad considerations, including the market opportunity, available expertise across the Company and the strength and efficacy of professionals’ collaboration, and not based upon profit or loss measures for the Company’s separate product lines. Since the financial markets are global in nature, the Company generally manages its business based on the operating results of the Company taken as a whole, not by geographic region. The following tables set forth the geographical distribution of revenues and assets based on the location of the office that generates the revenues or holds the assets and therefore may not be reflective of the geography in which the Company’s clients are located.
