Litigation funding—also called litigation finance or third-party funding—has a public face built partly on the conference circuit: private aviation, yacht receptions, open bars. That surface is real, and the events agencies that service the industry are happy to supply it. The substance underneath is drier and more interesting. It looks less like a party and more like insurance underwriting: a specialist investor reviews a large number of potential claims, prices the risk of losing, and advances money against a share of a recovery that may never arrive.
This article is about that substance—what the product is, how the money moves, how large the market appears to be, and how regulators in several jurisdictions are approaching disclosure. It is a description of mechanics and rules, not a judgment about the people who work in the field.
What third-party litigation funding actually is
Third-party litigation funding is an arrangement in which someone who is not a party to a lawsuit provides money to a claimant or a law firm in exchange for an interest in the potential recovery. The defining feature is that the money is non-recourse: if the case fails, the claimant is not obliged to repay the advance. The U.S. Government Accountability Office describes exactly this structure in its 2022 report on the market, noting that funders are paid from the proceeds of a successful claim rather than by fixed repayment.
Funding comes in two broad shapes. Single-case funding backs one dispute. Portfolio funding backs a bundle of cases, often through a facility extended to a law firm, and spreads risk across them. A related product, litigation insurance, covers the risk of an adverse costs order if the claim loses.
Payment is usually governed by a distribution clause—informally, a waterfall. The funder typically recovers its capital first, then an agreed return, after which the remaining proceeds are shared according to the agreement. That return may be expressed as a multiple of the amount advanced, a percentage of the recovery, or a rate of return, depending on the deal and the jurisdiction. Research for the Legal Services Board in the United Kingdom, published in May 2024, describes success fees being calculated either as a percentage of recovery or as a multiple of costs.
The economics are less glamorous than the imagery
If the conference circuit suggests easy money, the deal data points the other way. Funders are highly selective. Research commissioned by the Legal Services Board and carried out by Queen Mary University of London found that funders tend to accept only a small minority of the opportunities they review—a filter that reflects the cost of diligence and the reality that most claims are either too small or too uncertain to price.
Consumer funding shows how wide the gap can be between headline pricing and realized returns. A peer-reviewed study of more than 100,000 consumer funding requests over twelve years, published in the Cornell Law Review in 2018 by Ronen Avraham and Anthony Sebok, found a median contract markup of about 115%. After defaults and reductions, however, the median actual annual return was roughly 43%, and the funder lost money in about 12% of cases. Contract terms and outcomes are two different things.
At the other end of the market, the money is large and the timelines are long. The U.S. commercial market is dominated by a few dozen providers, and a single adverse ruling can reset a portfolio’s value. That is the risk being underwritten—not a lifestyle.
How big is the market? The estimates disagree
This is where careful readers should slow down. Commercial research firms publish global market figures that diverge sharply, largely because they define the market differently. For 2025 alone, published estimates ranged from roughly US$20.6 billion to about US$26.8 billion, depending on whether the count includes commercial funding, consumer advances, or broader legal-finance activity. Those figures come from commercial report sellers whose methodologies are not always public, so they are best treated as one input rather than a settled total.
Government and academic sources are narrower but firmer. The most authoritative picture of the U.S. commercial market comes from Westfleet Advisors, whose 2024 report counted 42 active capital providers holding about US$16.1 billion in assets under management, with new commitments falling 16% that year to roughly US$2.3 billion. Westfleet’s subsequent report found commitments rebounding about 23% in 2025, with an average deal of roughly US$8.1 million. Notably, Westfleet stopped publishing an industry-wide assets-under-management figure, saying that measure had been mischaracterized in policy debates—a useful reminder that a single number rarely captures the market.
| Market | Best available official or academic picture | Source |
|---|---|---|
| United Kingdom | Estimated at £1.5bn–£4.5bn; transparency and regulation under review | Civil Justice Council, June 2025 |
| European Union | Around 300 funders identified as active; 23 reported roughly 700 cases; typical funder share of recoveries 20–30% | European Commission mapping study, March 2025 |
| United States | No verified national total; 42 active commercial providers held about US$16.1bn AUM in 2024 | GAO, December 2022; Westfleet Advisors, March 2025 |
| Australia | Funders backed 46.2% of class actions nationally between 2012 and 2017 | Victorian Law Reform Commission, 2018 |
Source note: figures reflect the dates shown and use different definitions; they are not directly comparable. The U.S. Government Accountability Office found in its 2022 study that public data on the market are limited and that funders’ rates of return and total funding are not systematically reported.
Why the conference circuit looks the way it does
Industry conferences are a normal feature of capital-intensive professional services, from shipping to private equity. Litigation finance is no exception: annual gatherings mix panels on case law and pricing with receptions designed to put funders, law firms, and claimants in the same room. The hospitality is part of how deals and relationships get built, and it is not, by itself, evidence of anything about how the underlying business is conducted.
The more consequential story sits in the documents that rarely make a conference stage: the funding agreement, the waterfall clause, and—increasingly—the disclosure rules that determine whether a court is told who is paying for a case.
The transparency question
The central policy debate around litigation funding is not about hospitality. It is about disclosure: how much a court and the opposing party should know about who is funding a claim, and under what conditions.
In the United Kingdom, the Civil Justice Council published a final review of litigation funding on 2 June 2025. Its 58 recommendations include a transparency measure that would require the fact of funding, the funder’s name, and the ultimate source of the funds to be disclosed to the court and the other parties “at the earliest opportunity,” while generally leaving the detailed funding terms confidential. The review rejected caps on funder returns and recommended replacing self-regulation with a “light-touch” statutory framework.
Coverage of those proposals, including a June 2025 analysis of litigation funding transparency, has focused on how far courts should be told who is funding a case. The UK government said in December 2025 that it would legislate so that litigation funding agreements are not treated as damages-based agreements, and would introduce a framework for fairer, more transparent funding “when parliamentary time allows.” As of September 2026, no date for that legislation had been set.
The background to that commitment is a 2023 UK Supreme Court ruling, commonly known as PACCAR, which held that most percentage-based funding agreements were damages-based agreements and therefore subject to a different regulatory regime. An earlier Court of Appeal decision, Arkin v Borchard Lines in 2005, had addressed how far a funder can be liable for an opponent’s costs—the so-called Arkin cap, which generally limits that exposure to the amount the funder invested. These are technical points, but they shape how deals are written.
In the European Union, the European Parliament adopted a resolution in September 2022 calling on the Commission to propose common minimum standards for commercial third-party funding, including disclosure to the court of the existence of a funding agreement and, on request, its terms. The Commission followed with a mapping study published in March 2025, which found that most Member States have no funding-specific legislation and that transparency and capital-adequacy measures ranked among the most effective options considered. No EU directive has been proposed to date.
In the United States there is no nationwide federal disclosure requirement. The GAO confirmed in 2022 that the industry is not specifically regulated under federal law. Individual states have moved instead: Louisiana enacted what is widely described as the first general statutory disclosure requirement, effective in 2023, and by mid-2025 several states—among them Indiana, Kansas, Louisiana, Montana, Oklahoma, West Virginia, and Wisconsin—had adopted litigation-funding rules of varying scope, according to a survey by the law firm Redgrave LLP.
Both cases, stated fairly
The access-to-justice argument is straightforward and is accepted in part by official reviews: some claims are too expensive to bring without external capital, and funding can let a claimant pursue a meritorious case they could not otherwise afford. The Civil Justice Council, the European Commission’s mapping study, and academic work funded by the Legal Services Board all document this rationale.
The cautionary case is also structural rather than personal. It concerns the design of disclosure rules, the management of conflicts of interest, how adverse costs are allocated, and how much of a recovery reaches the claimant rather than the intermediaries. Australian data illustrate the issue without pointing at any individual: the Australian Law Reform Commission found that, for the period 2013–2018, the median return to class members was about 85% without a funder and about 51% with one. That is a distributional fact about how settlements are structured, and it is the kind of figure that regulators cite when weighing whether to impose caps or insist on disclosure. The Civil Justice Council, for its part, declined to recommend a cap.
What to watch
Three questions are likely to matter over the next few years. First, whether and when the UK legislates on the PACCAR point and the wider transparency framework. Second, whether the EU moves from study to a directive. Third, whether U.S. state disclosure laws keep spreading, and whether any federal rule emerges.
Underneath all three is a fourth issue: data. The GAO’s finding that funders’ returns and total funding are not systematically reported means that much of the public debate rests on estimates. Any reader comparing figures should check what each number actually counts before treating it as a market size.
Frequently asked questions
What is third-party litigation funding? It is an arrangement in which a party unrelated to a lawsuit provides capital to a claimant or law firm in return for a share of any recovery. The funding is usually non-recourse, meaning the claimant owes nothing if the case fails.
Is litigation funding lawful? It is lawful in many jurisdictions, including the UK, Australia, and much of the United States, though the rules differ. Some jurisdictions regulate it specifically, and others rely on general law and voluntary codes. Whether a particular agreement is enforceable can depend on the court and the applicable legal framework.
Who pays if the case loses? In typical non-recourse arrangements, the funder bears its own loss and the claimant does not repay the advance. The position on an opponent’s legal costs is separate and depends on the jurisdiction and the agreement; the Arkin cap in England and Wales, for example, generally limits a funder’s adverse-costs liability to what it invested.
Who regulates litigation funding? It varies. The UK has relied on a voluntary code through the Association of Litigation Funders, with the Civil Justice Council recommending a light-touch statutory scheme. The EU has no funding-specific directive. The United States has no nationwide disclosure rule, and individual states have enacted their own requirements. Australia regulates through its court and corporate-law frameworks.
How much of a recovery goes to a funder? There is no single figure. The European Commission’s 2025 mapping study reported a typical funder share of 20–30%, while the Australian Law Reform Commission found median returns to class members of about 51% where a funder was involved. Outcomes depend on the agreement, the jurisdiction, and the case.
Do claimants receive less when a funder is involved? Research and official data generally show a lower median return to claimants in funded cases than in unfunded ones, because part of the recovery compensates the funder for risk and capital. The size of that difference varies widely, and the trade-off is that some claims proceed only with external funding.
How this article was put together
This piece set out to explain the mechanics, scale, and regulation of third-party litigation funding for general readers, using primary and official sources wherever possible. It draws on the UK Civil Justice Council’s final review (June 2025), the UK government’s December 2025 statement, the European Commission’s mapping study (March 2025), the U.S. Government Accountability Office’s 2022 market report, Australian parliamentary and law-reform material, and peer-reviewed research in the Cornell Law Review (2018). Where sources disagree—particularly on global market size—the article says so rather than choosing a single number. Commercial market-research estimates were included only to illustrate the range. Figures are current as of the dates cited and will need rechecking as legislation develops, particularly in the UK and EU.
