A large legal claim can take years to resolve. Every month it stays open, it consumes money: court and filing fees, disclosure and document review, expert reports, counsel’s time, and the operating costs of the business or household behind the claim. When the sums in dispute are significant and the timetable is long, the gap between when costs are paid and when any recovery arrives can matter as much as the legal merits. Third-party litigation funding exists to bridge that gap.
Third-party litigation funding (TPLF), also called litigation finance, is an arrangement in which a party that is neither the claimant nor the lawyer provides capital to support a legal claim in exchange for a share of any eventual recovery. It appears in group actions, commercial disputes, insolvency claims, and international arbitration. This article explains how the model works, what it covers, how it is regulated in different jurisdictions, and where its limits lie.
What counts as a large-scale legal claim
Size is not only about the headline figure. A claim is generally described as large-scale when at least one of three conditions applies: the cost of running it is high relative to the resources of the party bringing it; the timeline is measured in years rather than months; or many claimants share a common grievance and must be organised into a single proceeding.
Antitrust litigation illustrates the first two. An analysis published by the law firm Foley & Lardner cites a study of 5,020 such cases filed in U.S. federal courts: the median time from filing to trial-level resolution was 1.8 years, the slowest 25% of cases averaged 4.9 years, and the slowest 10% averaged about eight years. In the two busiest venues, median times were 2.5 and three years. Those timelines shape everything that follows. The longer a case runs, the more capital it consumes before any recovery is realised.
Group and collective actions illustrate the third condition. Where widespread harm produces relatively modest individual losses, the cost of pursuing a single claim may exceed its value. Aggregation can make the dispute economically viable, and funding can support the costs of organising and running it.
How a litigation funding arrangement works
Most commercial funding is non-recourse. If the claim fails, the funder generally receives nothing, and the claimant is typically not required to repay the money advanced. If the claim succeeds, the funder receives an agreed return from the recovery. Because repayment is tied to the outcome, the arrangement is often treated as a form of investment or asset purchase rather than a loan, and it is usually not reported to credit bureaus.
Capital is commonly deployed on a drawdown basis, meaning funds are released as costs arise rather than as a single upfront lump sum. A litigation funding agreement (LFA) sets out what is covered, reporting obligations, the funder’s return, and what happens around settlement and termination.
Funders generally do not take control of the case. Day-to-day conduct typically remains with the claimant and their lawyers, while the agreement sets consultation and reporting expectations. In England and Wales, the voluntary Code of Conduct published by the Association of Litigation Funders includes assurances that a member will not seek to control the litigation or terminate funding without a material adverse development. The position may differ in other jurisdictions.
Returns are negotiated case by case. Practitioner guidance describes three broad structures, and actual terms depend on the case, jurisdiction, and agreement rather than any standard rate.
| Return structure | How it works | When it tends to be used |
|---|---|---|
| Multiple of deployed capital | The funder recovers its capital plus an agreed multiple. | Where budgets are clear and the case duration is reasonably measurable. |
| Percentage of recovery | The funder receives an agreed share of damages or settlement proceeds. | Where damages are large or outcomes vary significantly. |
| Hybrid or tiered | A combination, such as the lesser or greater of a multiple and a percentage. | Where parties want to align incentives across different scenarios. |
Why funders are used in group and collective actions
Collective redress has expanded in several jurisdictions, and funding has become a common feature of it. In the EU, the Representative Actions Directive (EU) 2020/1828 requires member states to provide for representative actions to protect consumers’ collective interests, and Article 10 addresses their funding. The European Commission’s mapping of third-party litigation funding across the EU found that most member states have no TPLF-specific regulation beyond the directive’s implementation, and noted that funding has a long tradition in jurisdictions such as Germany and the Netherlands.
In England and Wales, the Civil Justice Council’s Final Report on Litigation Funding (June 2025) recorded 27 funded collective proceedings before the Competition Appeal Tribunal as at March 2024, alongside further funded representative and group actions in the High Court. The same report traced the growth of UK funder assets from £198 million in 2011/12 to £2.2 billion a decade later, and described the UK market as one of the most developed in the world.
Funders typically assess three questions before committing: whether the claim is legally sound, what it is worth, and whether the defendant can pay. The last of these – enforceability – is often as important as the merits. A well-reasoned claim against a party with no assets or insurance may be difficult to fund, because a favourable judgment is only as useful as the ability to collect on it.
How funding changes case strategy
Costs in large claims are front-loaded. Disclosure, expert evidence, and procedural applications fall due early, while recovery may not arrive for years. Funding can cover not only legal fees but also disbursements such as court fees, expert reports, and document review, and in some jurisdictions it can help meet security for costs or adverse costs orders.
That has a second effect, on negotiation. A claimant able to meet costs as they arise is under less pressure to accept a discounted early settlement. Funders also spread risk across a portfolio of claims, which can allow them to support individual cases that would be difficult to finance on a standalone basis. Portfolio transactions have become a significant part of the market: Westfleet Advisors’ 2025 Litigation Finance Market Report, summarised by Risk & Insurance, recorded a rebound in new U.S. commitments of about 23% year on year in 2025, with portfolio deals accounting for 64% of new commitments and an average transaction size of roughly $8.1 million.
From an insurer’s perspective, understanding the economics behind a claim has become part of assessing exposure. Industry analysis notes that funding now often supports the wider infrastructure of a claim – claim identification, expert evidence, data management, and the operational requirements of claimant firms – and that who is financing a claim, and how, is increasingly relevant to how long it continues and when settlement becomes commercially attractive.
The market in numbers
Estimates of the size of the litigation funding market vary by methodology and should be read with care. One market report placed the global litigation funding investment market at about US$20.6 billion in 2025, projecting roughly US$51 billion by 2036, while another estimated US$22.8 billion in 2025 and about US$41 billion by 2030. What the estimates share is a direction of travel: sustained growth, supported by institutional capital and a broader range of users.

How litigation funding is regulated
The legal framework differs by jurisdiction, and the rules that apply to a specific claim depend on where it is brought.
| Jurisdiction | General approach |
|---|---|
| England & Wales | Permitted; historically self-regulated through the Association of Litigation Funders’ Code of Conduct. The 2023 PACCAR ruling raised enforceability questions; the Civil Justice Council’s 2025 report recommended light-touch statutory regulation. |
| EU member states | Most states have no TPLF-specific regulation beyond implementation of the Representative Actions Directive. |
| United States | State and federal rules overlap; older champerty and maintenance doctrines still limit some arrangements in some states. Disclosure requirements have grown through local rules and case-specific orders. |
| Australia | Funding arrangements have been linked historically to managed investment scheme rules; conflicts-management requirements flow from the Corporations Amendment Regulation 2012 and ASIC guidance. |
| Hong Kong / Singapore | Funding permitted in defined arbitration and related contexts since 2017, subject to codes of practice and court rules. |
| International arbitration | Allowed at many seats; disclosure requirements follow the chosen seat and the applicable institutional rules. |
In England and Wales, funding has been permitted since 1967, and a 2005 Court of Appeal decision confirmed it as a legitimate way to finance litigation. In 2023, the UK Supreme Court held in R (PACCAR) v Competition Appeal Tribunal that certain funding agreements were a form of damages-based agreement and therefore unenforceable under section 58AA of the Courts and Legal Services Act 1990. The Civil Justice Council’s 2025 report recommended legislation to reverse that effect and to introduce a “light-touch” statutory scheme. In December 2025 the government announced it would bring forward legislation to clarify that LFAs are not damages-based agreements, though no timeframe has been set.
In the United States, the picture is more fragmented. Courts have generally protected funding agreements from discovery where confidentiality measures are in place, while some courts have required disclosure where there is a specific, articulated risk of bias or conflict. As of April 2025, six states had enacted funding-disclosure requirements and roughly twenty others were considering similar measures, according to analysis of state legislative activity. Several federal district courts, including the District of New Jersey and the Northern District of California, have adopted local rules or standing orders requiring disclosure, and a federal Advisory Committee on Civil Rules subcommittee began examining the issue in late 2024.
Where the debate focuses
There is no consensus on how far funding should be regulated. The European Commission’s mapping exercise found that 58% of surveyed stakeholders saw a need for regulation at EU or national level, but views differed sharply by group: majorities of judiciary, business, and academic respondents favoured regulation, while consumer organisations and funders largely did not, and a majority of public authorities answered “don’t know.”
In England and Wales, the Civil Justice Council recommended a regulatory scheme covering capital adequacy, conflicts of interest, anti-money laundering, and disclosure of the fact of funding, while expressly rejecting caps on funders’ returns. Much of the current discussion concerns mechanics – how arrangements are structured, disclosed, and reviewed – rather than whether funding should exist. A 2022–2023 review by the Delaware Supreme Court’s Committee on Litigation Funding and Transparency, cited in submissions to the federal Advisory Committee, concluded that there was no evidence of systemic problems in the state courts, while recommending a narrow tool to address whether anyone other than the litigant controls a case.
Limits of the model
Funding does not make a weak claim viable, and it does not guarantee an outcome. It also does not replace legal advice. The cost of capital is real: a claimant weighs the share of any recovery that goes to the funder against the alternative of not bringing the claim at all. Because terms depend on the case, the jurisdiction, and the agreement, there is no single standard rate or structure.
Eligibility is also selective. Most commercial funders expect the claimant to have legal representation and focus on claims with a clear legal basis, meaningful damages, and a defendant able to pay. Some fund smaller matters through portfolio structures; others concentrate on particular categories of dispute.
Frequently asked questions
Is litigation funding a loan?
Generally not. In a typical non-recourse arrangement, the funder is repaid only if the claim succeeds, which is why the structure is usually treated as an investment or asset purchase rather than a loan. Some consumer products and some jurisdictions use different labels and apply different rules.
Who controls the case when it is funded?
In most funded structures the claimant and their lawyers retain day-to-day control. The agreement typically sets reporting and consultation expectations, particularly around settlement. In England and Wales, the voluntary Code of Conduct includes assurances against funder control; arrangements elsewhere can differ.
Does funding guarantee that a claim will succeed or be accepted?
No. Funders screen cases closely and decline many of them. A funding decision reflects an assessment of merits, damages, and enforceability, but it does not determine the legal outcome, which only a court or tribunal can do.
How much of a recovery does a funder typically receive?
Returns are negotiated case by case and are commonly structured as a multiple of the capital deployed, a percentage of the recovery, or a hybrid of the two. There is no universal rate, and terms vary with risk, duration, and expected recovery.
Can individuals use litigation funding?
In some contexts, yes. Consumer products exist, particularly in personal injury and pre-settlement advances, though they are often structured differently from commercial funding. Many commercial funders focus on higher-value claims or portfolios.
Is litigation funding legal?
It is permitted in many jurisdictions, but the rules and degree of regulation vary. Some jurisdictions regulate it specifically; others rely on general contract law, codes of conduct, or court oversight. Whether a particular arrangement is enforceable depends on the applicable law and how the agreement is structured.
Litigation funding does not decide the merits of a dispute, and it does not guarantee any outcome. What it can do is resource a claim with genuine legal merit long enough to reach a decision. For claimants and their advisers, the practical starting point is a candid assessment of three things – legal strength, damages, and enforceability – the same questions a funder applies during due diligence. Where those conditions are met, funding can bring a claim that is economically out of reach within reach. Where they are not, the difficulty in attracting capital is itself a signal about how the claim’s practical prospects are likely to be viewed.
