Complex litigation rarely starts with a single billable hour. It starts with expert reports, disclosure exercises, court fees, counsel’s fees and years of preparatory work, most of which are incurred long before there is any judgment or settlement to draw on. The central financing question for a law firm is therefore not only who pays the lawyers, but which balance sheet can carry the cost between instruction and resolution, and who absorbs the loss if the claim does not succeed.
That question has produced a layered market. Large disputes can now be capitalised through firm-level bank facilities, case-level funding from specialist investors, contingency fees, and insurance products that cap the downside. None of these structures is universal, and each carries its own regulatory and commercial conditions.
Why complex litigation creates a financing problem
Complex matters are expensive to run and slow to resolve. Multi-party claims, international arbitration, competition damages actions and mass torts typically involve large document sets, several expert disciplines, and procedural stages spread over several years. Costs are front-loaded; recovery is back-loaded.
A second feature sets litigation apart from ordinary commercial projects: the outcome is uncertain, and in most common-law jurisdictions the losing party may also be ordered to pay a portion of the winner’s costs. That combination – high fixed outlays, delayed and contingent recovery, plus potential adverse costs – is what makes litigation a financing problem rather than a simple budgeting exercise.
Firms respond at three different levels: they borrow against the practice, they finance a specific case, or they structure the client’s own payment obligations. The right choice depends on the type of work, the firm’s cash position and the jurisdiction.
Three balance sheets are usually involved
When the firm itself borrows
Law firm finance is largely ordinary business finance: revolving lines of credit for working capital, term loans for premises and technology, and – for contingency practices – case cost facilities secured against the firm’s inventory of active matters. A firm draws on a case cost line to pay expert witnesses, depositions, medical records and filing fees, then repays out of fees as matters resolve.
Partnership capital is the other traditional source. New partners are generally required to contribute capital, and many borrow to do so through partner capital loan programmes sponsored by banks that specialise in professional practices. This spreads the firm’s funding base across its owners rather than concentrating it in one lender relationship.
When the case carries the cost
Case-level finance is where litigation differs from most industries. Disbursement funding lenders advance the outlays on a specific matter and are repaid, with a fee or interest, when it settles. Third-party litigation funding goes further: an external funder pays part or all of the claimant’s legal budget on a non-recourse basis, meaning the funder recovers nothing if the claim fails, and in exchange takes an agreed return if it succeeds.
Portfolio funding applies the same logic across a group of cases, allowing a funder to spread risk rather than betting on a single outcome. For the firm, portfolio arrangements can also support the running of the practice as a whole, not just one claim.
When the client’s recovery funds the claim
Some arrangements shift the burden to the client side. Conditional fee agreements (CFAs), commonly called “no win, no fee,” allow a lawyer to charge a reduced fee during the case and an uplift – the success fee – if the client wins. Damages-based agreements (DBAs) go further: the lawyer’s fee is calculated as a percentage of the sum recovered rather than by reference to time spent, and no fee is payable if the case fails.
Before-the-event (BTE) legal expenses insurance, often attached to home, motor or membership products, can fund advice and representation for disputes that arise later, although policy limits are frequently modest relative to complex commercial claims. Pre-settlement funding, by contrast, is a cash advance to an individual claimant to cover living costs while a case is pending, and is a consumer product rather than commercial litigation finance.
The main instruments, compared
The table below sets out the core structures and what each is designed to do. The most useful distinction is not the label on the product but who provides the capital and what triggers repayment.
| Instrument | Capital comes from | Repaid from | Typical use |
|---|---|---|---|
| Third-party litigation funding (single case) | Specialist funders and private capital | Agreed share of any recovery; funder loses its investment if the claim fails | Large commercial claims, arbitration, group actions |
| Portfolio funding | Specialist funders | Agreed return drawn across multiple resolved matters | Spreading risk across a firm’s casebook |
| Disbursement funding | Specialist lenders and banks | Repayment plus interest or fee on resolution | Outlay-heavy caseloads: experts, court fees, counsel |
| After-the-event (ATE) insurance | Insurers | Deferred or contingent premium, usually met from recovery | Costs protection against adverse costs and lost disbursements |
| Conditional fee agreement (CFA) | Law firm and barristers | Discounted base costs plus success fee on success | Damages claims where the client cannot fund hourly fees |
| Damages-based agreement (DBA) | Law firm and barristers | Percentage of sums recovered, within regulatory caps | Contentious civil work outside excluded categories |
| Firm-level credit | Banks and specialty lenders | Fee income, on a fixed schedule or as cases resolve | Payroll, operations and case costs across the practice |
Structures summarised from the Civil Justice Council’s Review of Litigation Funding (June 2025), the Ministry of Justice’s post-implementation review of LASPO Part 2, and published dispute-resolution client guidance. Terms vary by jurisdiction, case type and the terms of the individual agreement.
How a third-party funder decides whether to invest
A funder is underwriting an uncertain legal outcome, so its assessment resembles an investment appraisal more than a credit check. The questions typically include the legal merits, the value and enforceability of any eventual award, the expected duration, the credibility of the defendant’s ability to pay, and the size and controllability of the budget.
Because many common-law systems allow costs to follow the event, funders commonly require after-the-event insurance as a condition of funding, so that adverse costs are covered if the claim fails. Funders also generally require that the client and its lawyers retain control of the conduct of the case – a funder taking day-to-day control would risk offending the historic prohibitions on maintenance and champerty, under which a third party may not improperly stir up or fund litigation for profit.
Returns are usually expressed either as a multiple of the capital invested or, where permitted, as a percentage of the recovery. The precise terms vary widely with the assessed risk and duration, which is why published examples should be treated as illustrations rather than standard rates.
Contingency fees and the regulatory backdrop
In England and Wales, the funding landscape was reshaped by Part 2 of the Legal Aid, Sentencing and Punishment of Offenders Act 2012, which took effect on 1 April 2013. The Ministry of Justice’s own post-implementation review records that success fees under conditional fee agreements, and after-the-event insurance premiums, ceased to be recoverable from the losing party for agreements entered into on or after that date. In practice this means those costs are usually met from the client’s damages rather than added to the bill against the opponent, subject to limited exceptions such as an element of the premium relating to expert reports in clinical negligence claims.
DBAs were extended to most contentious civil work at the same time and are subject to statutory caps – in commercial cases, generally up to 50 per cent of the sums ultimately recovered. Take-up was initially slow, partly because the regulations were widely regarded as unclear, and hybrid arrangements that combine a DBA with other funding have been a particular focus of reform discussion.
The regulatory picture continued to move after a 2023 Supreme Court judgment – generally referred to as the PACCAR decision – held that funding agreements in which the funder’s return was calculated as a share of damages fell within the statutory definition of a damages-based agreement. The Civil Justice Council’s Review of Litigation Funding, published in June 2025, made a series of recommendations to restore enforceability and to introduce a proportionate, light-touch regulatory regime. In December 2025 the government indicated its intention to legislate to reverse the effect of that judgment, though the timing of any change remains uncertain. Readers tracking the detail can follow the analysis in this overview of an inflexion point for litigation funding.
Funding arrangements also sit inside a wider framework of professional regulation and court rules. Keeping abreast of legal sector developments across jurisdictions has become part of routine dispute planning for firms and their advisers, because the availability and enforceability of a funding structure can turn on rules that differ from one market to the next.
Insurance is what makes many structures viable
After-the-event insurance is not a source of capital in the way a funder is, but it is often the piece that makes other structures workable. A typical policy covers the insured’s exposure to the opponent’s costs if the case is lost, and sometimes its own disbursements as well. The premium is frequently deferred and contingent on success, which allows a claimant without substantial reserves to run a case at all.
In personal injury litigation in England and Wales, qualified one-way costs shifting (QOCS) provides an additional layer of protection, meaning an unsuccessful claimant generally does not have to pay the defendant’s costs, subject to defined exceptions. ATE insurance can also serve as security for costs where the court requires it.
The disclosure debate in the United States
The United States has no single federal disclosure rule for third-party litigation funding. Practice varies between states and between federal districts, with some courts adopting local rules or standing orders requiring parties to identify funders, and others declining to order disclosure.
That inconsistency has prompted federal activity. A bill introduced in the 119th Congress, the Litigation Funding Transparency Act of 2026, would require disclosure of third-party funders in certain class and mass actions, while the Advisory Committee on Civil Rules has been considering an amendment to the initial-disclosure provisions of the Federal Rules of Civil Procedure. You can follow the proposed statutory text on Congress.gov. At the same time, a small number of states have moved in the opposite direction, and one state has enacted a restriction on certain funding arrangements. The practical effect for parties is that funding structures need to be assessed against the specific forum, not against a single national rule.
What can go wrong – and how it is managed
Financing complex litigation introduces risks that are not present in ordinary fee-for-service work. A case may take longer than modelled, which increases the accumulated cost before any recovery. A funder may find itself exposed across several matters if a portfolio performs worse than expected. Adverse costs can crystallise before the merits are resolved. And because funding arrangements involve a third party, issues of confidentiality, privilege and potential conflicts require careful handling.
Firms and funders manage these risks through staged capital deployment, costs budgeting, regular case reviews, and clear contractual allocation of who bears what. Funders typically build in capital adequacy requirements and, where the funded party is not a commercial entity, may insist on ATE insurance. In England and Wales, funders who are members of the Association of Litigation Funders also commit to a voluntary Code of Conduct; the regime has historically been self-regulatory, and proposals for statutory oversight remain the subject of consultation.
One point that is often understated: a funding agreement is a commercial contract, and its enforceability depends on compliance with the relevant regulatory regime. Where the law changes, or where an agreement is found not to satisfy a statutory definition, the consequences can affect the whole funding structure. Legal advice on the agreement itself is therefore as important as advice on the merits of the claim.
Frequently asked questions
Is third-party litigation funding lawful?
In England and Wales it is generally lawful provided the funder does not control the conduct of the litigation. It is also established in many other jurisdictions, including Australia, Germany and the United States, though the rules differ. In some US states particular arrangements are restricted or disclosure is required, so the position depends on the forum.
Who pays if the claim fails?
Under non-recourse funding, the client typically owes the funder nothing and the funder loses the capital it advanced. Under a CFA or DBA, the lawyer is generally not paid. The client may still face an adverse costs order if the case is lost, which is the exposure that ATE insurance is designed to cover.
Do funders control the litigation?
Generally not. Funders typically agree contractual terms that preserve the client’s and the lawyers’ control over the conduct and settlement of the case. A funder exercising improper control could threaten the enforceability of the agreement and raise concerns under the rules on maintenance and champerty.
Is the after-the-event insurance premium recoverable from the losing party?
In England and Wales, generally not for agreements entered into on or after 1 April 2013, following the LASPO reforms. There are limited exceptions, such as certain expert-report costs in clinical negligence claims. The premium is usually met from the client’s recovery.
How long does it take to put third-party funding in place?
It depends on the complexity of the case and the funder’s due diligence. Published client guidance from dispute-resolution practices frequently refers to a period of several weeks or more for larger commercial matters, but timelines vary and should not be treated as fixed.
Can a firm combine several funding methods?
Yes. Hybrid structures that pair a conditional or damages-based agreement with insurance, or with third-party funding for disbursements, are used in practice. Their lawfulness and the caps that apply depend on the jurisdiction and the specific agreements involved.
The direction of travel
Litigation finance has moved from an emergency measure for claimants who could not otherwise afford to sue into a recognised part of dispute planning, sitting alongside insurance and settlement strategy. A decade ago, arranging funding was often treated as a sign that a case could not stand on its own; today it is more commonly a deliberate allocation of risk between the party, its lawyers and its capital providers.
What will decide how quickly that market matures is not demand but certainty – the enforceability of agreements, the clarity of regulatory caps, and consistent rules on disclosure. For a law firm weighing how to fund a complex matter, the practical task is to map the available instruments onto the specific case, the client’s appetite for risk, and the rules of the forum, then to document the arrangement so that it survives scrutiny. The mechanics are well established; it is the regulatory detail that keeps changing, and that is where the advice earns its place.
