Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Information	INTERIM INFORMATION Readers of this quarterly report should refer to the audited financial statements of Jones Lang LaSalle Incorporated ("JLL," which may also be referred to as "the Company" or as "we," "us" or "our") for the year ended December 31, 2022, which are included in our 2022 Annual Report on Form 10-K, filed with the United States Securities and Exchange Commission ("SEC") and also available on our website ( www.jll.com ), since we have omitted from this quarterly report certain footnote disclosures which would substantially duplicate those contained in such audited financial statements. You should also refer to the "Summary of Critical Accounting Policies and Estimates" section within Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and to Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements in our 2022 Annual Report on Form 10-K for further discussion of our significant accounting policies and estimates. Our Condensed Consolidated Financial Statements as of March 31, 2023, and for the periods ended March 31, 2023 and 2022, are unaudited. In the opinion of management, we have included all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of the Condensed Consolidated Financial Statements for these interim periods. Historically, our quarterly revenue and profits have tended to increase from quarter to quarter as the year progresses. This is the result of a general focus in the real estate industry on completing transactions by calendar year end, while certain expenses are recognized evenly throughout the year. Growth in our Property Management and Workplace Management businesses as well as other annuity-based services has, to an extent, lessened the seasonality in our revenue and profits during the past several years. Within our Markets Advisory and Capital Markets segments, revenue from transaction-based activities is driven by the size and timing of our clients' transactions and can fluctuate significantly from period to period. Our LaSalle Investment Management ("LaSalle") segment generally earns investment-generated performance fees on clients' real estate investment returns when assets are sold, the timing of which is geared toward the benefit of our clients, as well as co-investment equity gains and losses, primarily dependent on underlying valuations. A significant portion of our compensation and benefits expense is from incentive compensation plans, which we generally accrue throughout the year based on progress toward annual performance targets. This process can result in significant fluctuations in quarterly compensation and benefits expense from period to period. Non-variable operating expenses, which we recognize when incurred during the year, are relatively constant on a quarterly basis. We provide for the effects of income taxes on interim financial statements based on our estimate of the effective tax rate for the full year, which we base on forecasted income by country and expected enacted tax rates. As required, we adjust for the impact of discrete items in the quarters in which they occur. Changes in the geographic mix of income can impact our estimated effective tax rate. As a result of the items mentioned above, the results for the periods ended March 31 are not fully indicative of what our results will be for the full fiscal year.

Revenue from Contract with Customer [Text Block]	REVENUE RECOGNITION Capital Markets revenue excluded from the scope of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC Topic 606") Our mortgage banking and servicing operations, comprised of (i) all Loan Servicing revenue and (ii) activities related to mortgage servicing rights ("MSR" or "MSRs") and loan origination fees (included in Investment Sales, Debt/Equity Advisory and Other), are not considered revenue from contracts with customers, and accordingly are excluded from the scope of ASC Topic 606. Such out-of-scope revenue is presented below.

The majority of contract liabilities are recognized as revenue within 90 days. Such contract assets and liabilities are presented below.

As of March 31, 2023, the aggregate amount of transaction price allocated to remaining performance obligations represented less than 5% of our total revenue. In accordance with ASC Topic 606, excluded from the aforementioned remaining performance obligations are (i) amounts attributable to contracts expected to be completed within 12 months and (ii) variable consideration for services performed as a series of daily performance obligations, such as facilities management, property management and LaSalle contracts. A significant portion of our customer contracts, which are not expected to be fulfilled within 12 months, are represented by the contracts within these businesses.

Business Segments

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS We manage and report our operations as five global business segments: (1) Markets Advisory, (2) Capital Markets, (3) Work Dynamics, (4) JLL Technologies, and (5) LaSalle. Markets Advisory offers a wide range of real estate services, including agency leasing and tenant representation, property management, advisory and consulting services. Capital Markets service offerings include investment sales, equity and debt advisory, loan servicing and valuation advisory. Our Work Dynamics business provides a broad suite of integrated services to occupiers of real estate, including facility and project management, as well as portfolio and other services. Our JLL Technologies segment offers software products, solutions and services, while LaSalle provides investment management services on a global basis to institutional investors and high-net-worth individuals. We allocate all indirect expenses to our segments, other than interest and income taxes, as nearly all expenses incurred benefit one or more of the segments. Allocated expenses primarily consist of corporate functional costs across the globe, which we allocate to the business segments using an expense-specific driver-based methodology. Adjusted EBITDA does not include (i) Restructuring and acquisition charges, (ii) gain/loss on disposal, (iii) interest on employee loans, net of forgiveness, (iv) net non-cash MSR and mortgage banking derivative activity, (v) Interest expense, net of interest income, (vi) Income tax (benefit) provision and (vii) Depreciation and amortization, which are otherwise included in Net income on the Condensed Consolidated Statements of Comprehensive Income. The Chief Operating Decision Maker ("CODM") of JLL measures and evaluates the segment results based on Adjusted EBITDA for purposes of making decisions about allocating resources and assessing performance. Our CODM is not provided with total asset information by segment and accordingly does not measure or allocate resources based on total assets information. Therefore, we have not disclosed asset information by segment. Summarized financial information by business segment is as follows.

We have maximum potential unfunded commitments to direct investments or investment vehicles of $326.9 million and $16.0 million as of March 31, 2023 for our LaSalle Investment Management business and JLL Technologies, respectively. Of the $326.9 million related to LaSalle, while we remain contractually obligated, we do not expect a call on the $60.3 million relating to a specific investment since the underlying fund moved into its liquidation phase in January 2020. We evaluate our less-than-wholly-owned investments to determine whether the underlying entities are classified as variable interest entities ("VIEs"); we assess each identified VIE to determine whether we are the primary beneficiary. In prior periods, we determined we were the primary beneficiary of certain VIEs and, accordingly, we consolidated such entities. In December of 2022, as a result of a reconsideration event, we concluded we were no longer the primary beneficiary of these VIEs and, therefore, no longer consolidate these VIEs. Summarized financial information for our consolidated VIEs is presented in the following table. As a result of the reconsideration event described above, there were no consolidated VIE balances as of March 31, 2023 and December 31, 2022; net income was consolidated up to the reconsideration date. Three Months Ended March 31, (in millions) 2023 2022 Revenue $ — 3.5 Operating and other expenses — (5.7) Net loss $ — (2.2) We allocate the net loss of the consolidated VIEs to the noncontrolling interest holders as Net income (loss) attributable to noncontrolling interest in our Condensed Consolidated Statements of Comprehensive Income. Impairment There were no significant other-than-temporary impairment charges on investments for the three months ended March 31, 2023 and 2022. Fair Value We report a majority of our investments at fair value. For such investments, we increase or decrease our investment each reporting period by the change in the fair value and we report these fair value adjustments in our Condensed Consolidated Statements of Comprehensive Income within Equity earnings.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS We measure certain assets and liabilities in accordance with ASC Topic 820, Fair Value Measurements and Disclosures , which defines fair value as the price that would be received for an asset, or paid to transfer a liability, in an orderly transaction between market participants on the measurement date. In addition, it establishes a framework for measuring fair value according to the following three-tier fair value hierarchy: • Level 1 - Quoted prices for identical assets or liabilities in active markets accessible as of the measurement date; • Level 2 - Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and • Level 3 - Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Financial Instruments Our financial instruments include Cash and cash equivalents, Trade receivables, Notes and other receivables, Reimbursable receivables, Warehouse receivables, restricted cash, contract assets, Accounts payable, Reimbursable payables, Short-term borrowings, contract liabilities, Warehouse facilities, Credit facility, Long-term debt and foreign currency forward contracts. The carrying amounts of Cash and cash equivalents, Trade receivables, Notes and other receivables, Reimbursable receivables, restricted cash, contract assets, Accounts payable, Reimbursable payables, contract liabilities and the Warehouse facilities approximate their estimated fair values due to the short-term nature of these instruments. The carrying values of our Credit facility and Short-term borrowings approximate their estimated fair values given the variable interest rate terms and market spreads. We estimated the fair value of our Long-term debt using dealer quotes that are Level 2 inputs in the fair value hierarchy. The fair value and carrying value of our debt are presented in the following table. (in millions) March 31, 2023 December 31, 2022 Long-term debt, fair value $ 360.1 360.9 Long-term debt, carrying value, net of debt issuance costs 379.2 372.8 Investments at Fair Value - Net Asset Value ("NAV") We report a significant portion of our investments at fair value. For such investments, we increase or decrease our investment each reporting period by the change in the fair value, and we report these fair value adjustments in our Condensed Consolidated Statements of Comprehensive Income within Equity earnings. For a subset of our investments reported at fair value, we estimate the fair value using the NAV per share (or its equivalent) our investees provide. Critical inputs to NAV estimates included valuations of the underlying real estate assets and borrowings, which incorporate investment-specific assumptions such as discount rates, capitalization rates, rental and expense growth rates, and asset-specific market borrowing rates. We did not consider any adjustments to NAV estimates provided by investees, including adjustments for any restrictions to the transferability of ownership interests embedded within investment agreements to which we are a party, to be necessary based upon (i) our understanding of the methodology utilized and inputs incorporated to estimate NAV at the investee level, (ii) consideration of market demand for the specific types of real estate assets held by each venture and (iii) contemplation of real estate and capital markets conditions in the localities in which these ventures operate. As of March 31, 2023 and December 31, 2022, investments at fair value using NAV were $303.5 million and $284.6 million, respectively. As these investments are not required to be classified in the fair value hierarchy, they have been excluded from the following table. Recurring Fair Value Measurements The following table categorizes by level in the fair value hierarchy the estimated fair value of our assets and liabilities measured at fair value on a recurring basis. March 31, 2023 December 31, 2022 (in millions) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets Investments - fair value $ 55.5 — 466.5 58.3 — 452.0 Foreign currency forward contracts receivable — 4.9 — — 3.7 — Warehouse receivables — 881.6 — — 463.2 — Deferred compensation plan assets — 551.3 — — 517.9 — Mortgage banking derivative assets — — 155.2 — — 190.2 Total assets at fair value $ 55.5 1,437.8 621.7 58.3 984.8 642.2 Liabilities Foreign currency forward contracts payable $ — 3.9 — — 4.8 — Deferred compensation plan liabilities — 507.9 — — 485.4 — Earn-out liabilities — — 73.1 — — 73.2 Mortgage banking derivative liabilities — — 142.4 — — 169.5 Total liabilities at fair value $ — 511.8 215.5 — 490.2 242.7 Investments We classify one investment as Level 1 in the fair value hierarchy as quoted price are readily available. We increase or decrease our investment each reporting period by the change in the fair value of the investment. We report the fair value adjustments in our Condensed Consolidated Statements of Comprehensive Income within Equity earnings. Investments classified as Level 3 in the fair value hierarchy represent investments in early-stage non-public entities where we elected the fair value option. The carrying value was deemed to approximate fair value for the majority of these investments due to the proximity of the investment date or date of most recent financing raise to the balance sheet date as well as consideration of investee-level performance updates. To the extent there are changes in fair value, a result of pricing in subsequent funding rounds or changes in business strategy, for example, we recognize such changes through Equity earnings. Foreign Currency Forward Contracts We regularly use foreign currency forward contracts to manage our currency exchange rate risk related to intercompany lending and cash management practices. We determine the fair values of these contracts based on current market rates. The inputs for these valuations are Level 2 inputs in the fair value hierarchy. The following table details the gross notional value and net basis of these contracts. (in billions) March 31, 2023 December 31, 2022 Foreign currency forward contracts, gross notional value $ 1.79 1.81 Foreign currency forward contracts, net basis 0.90 1.02 We record the asset and liability positions for our foreign currency forward contracts based on the net payable or net receivable position with the financial institutions from which we purchase these contracts. The outstanding balances of these contracts are presented in the following table. (in millions) March 31, 2023 December 31, 2022 Net asset, receivable positions $ 6.7 7.7 Net asset, payable positions (1.8) (4.0) Foreign currency forward contracts receivable $ 4.9 3.7 Net liability, receivable positions $ (1.5) (1.6) Net liability, payable positions 5.4 6.4 Foreign currency forward contracts payable $ 3.9 4.8 Warehouse Receivables As of March 31, 2023 and December 31, 2022, all of our Warehouse receivables were under commitment to be purchased by government-sponsored enterprises ("GSEs") or by a qualifying investor as part of a U.S. government or GSE mortgage-backed security program. Deferred Compensation Plan We maintain a deferred compensation plan for certain of our U.S. employees that allows them to defer portions of their compensation. We recorded this plan on our Condensed Consolidated Balance Sheet as of March 31, 2023 as Deferred compensation plan assets of $551.3 million, long-term deferred compensation plan liabilities of $507.9 million, included in Deferred compensation, and as a reduction of equity, Shares held in trust, of $9.8 million. We recorded this plan on our Condensed Consolidated Balance Sheet as of December 31, 2022 as Deferred compensation plan assets of $517.9 million, long-term deferred compensation plan liabilities of $485.4 million, included in Deferred compensation, and as a reduction of equity, Shares held in trust, of $9.8 million. Earn-Out Liabilities We classify our Earn-out liabilities within Level 3 in the fair value hierarchy because the inputs we use to develop the estimated fair value include unobservable inputs. See Note 5, Business Combinations, Goodwill and Other Intangible Assets, for additional discussion of our Earn-out liabilities. Mortgage Banking Derivatives Both our interest rate lock commitments to prospective borrowers and forward sale contracts with prospective investors are undesignated derivatives and considered Level 3 valuations due to significant unobservable inputs related to counterparty credit risk. An increase in counterparty credit risk assumptions would result in a lower fair value measurement. The tables below present a reconciliation for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). For the comparative period, we have reclassified certain investments previously reported as NAV investments to Level 3 to conform with current presentation.

When the carrying amount of the investment is in excess of the estimated future undiscounted cash flows, we use a discounted cash flow approach or other acceptable method to determine the fair value of the investment in computing the amount of the impairment. Our determination of fair value primarily relies on Level 3 inputs. We did not recognize any significant investment-level impairment losses during either of the three months ended March 31, 2023 or 2022. See Note 6, Investments, for additional information, including information related to impairment charges recorded at the investee level.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES We are a defendant in various litigation matters arising in the ordinary course of business, some of which involve claims for damages that are substantial in amount. Professional Indemnity Insurance In order to better manage our global insurance program and support our risk management efforts, we supplement our traditional insurance coverage for certain types of claims by using a wholly-owned captive insurance company. The level of risk retained by our captive insurance company, with respect to professional indemnity claims, is up to $10.0 million per claim, inclusive of the deductible. We contract third-party insurance companies to provide coverage of risk in excess of this amount. When a potential loss event occurs, we estimate the ultimate cost of the claim and accrue the amount in Other current and long-term liabilities on our Condensed Consolidated Balance Sheets when probable and estimable. In addition, we have established receivables from third-party insurance providers for claim amounts in excess of the risk retained by our captive insurance company. In total, these receivables were $22.5 million as of both March 31, 2023 and December 31, 2022 and are included in Notes and other receivables on our Condensed Consolidated Balance Sheets. The following table shows the professional indemnity accrual activity and related payments. (in millions) December 31, 2022 $ 2.2 New claims 0.1 Prior year claims adjustments (including foreign currency changes) — Claims paid — March 31, 2023 $ 2.3 December 31, 2021 $ 1.2 New claims — Prior year claims adjustments (including foreign currency changes) — Claims paid — March 31, 2022 $ 1.2 Delegated Underwriting and Servicing ("DUS") Program Loan Loss-Sharing As a participant in the DUS program, we retain a portion of the risk of loss for loans that are originated and sold under the DUS program. Net losses on defaulted loans are shared with Fannie Mae based upon established loss-sharing ratios. Generally, we share approximately one-third of incurred losses, subject to a cap of 20% of the principal balance of the mortgage at origination. As of March 31, 2023 and December 31, 2022, we had loans, funded and sold, subject to such loss-sharing arrangements with an aggregate unpaid principal balance of $18.9 billion and $18.3 billion, respectively. For all DUS program loans with loss-sharing obligations, we record a non-contingent liability equal to the estimated fair value of the guarantee obligations undertaken upon sale of the loan, which reduces our gain on sale of the loan. Subsequently, this liability is amortized over the estimated life of the loan and recognized as Revenue on the Condensed Consolidated Statements of Comprehensive Income. As of March 31, 2023 and December 31, 2022, the loss-sharing guarantee obligations were $28.9 million and $29.0 million, respectively, and are included in Other liabilities on our Condensed Consolidated Balance Sheets. There were no loan losses incurred during the three months ended March 31, 2023 and 2022.
