Third-party litigation funding is an arrangement where an outside investor pays for the costs of a lawsuit in exchange for a share of any money the case recovers. The funder is not part of the lawsuit itself. If the case loses, the funder usually receives nothing.

This practice has grown quickly over the past twenty years. Industry estimates put total litigation funding investments near $18.9 billion in 2025, with much of that money coming from private firms, hedge funds, and other investors.

Supporters say it gives people and businesses a way to pursue valid claims they could not otherwise afford. Critics raise concerns about disclosure, cost, and who really controls a case. The sections below explain how these deals work, who uses them, and what rules apply.

Core Structure And Participants

Every litigation funding deal involves three main players: the funder who supplies the money, the claimant who owns the legal claim, and the lawyers who handle the case. The money itself comes with a specific condition — repayment depends on winning.

Funders, Claimants, And Legal Counsel

The funder is usually a private investment firm, hedge fund, or specialty finance company. These firms raise money from outside investors and then review claims to decide which ones to back.

The claimant can be an individual plaintiff, a small business, or a large corporation. They receive capital to pay legal fees, expert witnesses, court costs, and sometimes personal or operating expenses while the case moves forward.

Legal counsel stays in charge of the case strategy. Most funding agreements state that the funder does not direct settlement decisions, though critics argue this line can blur in practice.

In some deals, the money goes to the law firm instead of the client. A firm might use it to cover staff time across a group of contingency-fee cases.

Non-Recourse Capital And Contingent Returns

Nearly all commercial litigation funding is non-recourse. If the case fails, the claimant owes nothing back.

That risk shapes how funders get paid. Instead of interest on a loan, they take an agreed share of any settlement or judgment.

Because losses are absorbed entirely by the funder, they screen cases closely. Reviewers look at the strength of the legal claim, the defendant’s ability to pay, and whether the expected award justifies the cost of pursuing it.

How Funding Arrangements Operate

Funding a case follows a clear path. A funder first studies the claim to decide if it is worth the risk, then both sides sign a contract that spells out who gets paid and in what order.

Case Evaluation And Underwriting

Before any money moves, the funder reviews the case. This review is called underwriting, and it often takes several weeks.

Funders usually look at a few key points:

• Merits of the claim — the legal theory, evidence, and strength of the pleadings
• Damages — how much money the case could realistically recover
• Collectability — whether the defendant can actually pay a judgment
• Budget — expected costs for attorney fees, experts, e-discovery, and court fees
• Timeline — how long the case may take to resolve

Many funders apply a ratio test. They often want the expected recovery to be several times larger than the amount they invest.

Lawyers typically share case documents under a nondisclosure agreement during this stage. Most submissions are declined, since funders back only a small share of the claims they review.

Agreement Terms And Payment Waterfalls

The funding agreement sets the price of the capital and the order of payment. Because the money is non-recourse, the funder collects nothing if the case loses.

Returns are usually structured in one of these ways:

Proceeds are then distributed through a waterfall, which is simply a ranked list of who gets paid first.

A common order is: case expenses, then the funder’s return of capital and profit, then attorney fees, with the remaining balance going to the claimant.

Agreements also address control. Standard terms leave settlement decisions with the client and the lawyer, though the funder may ask for status updates or notice of major offers.

Common Forms Of Litigation Finance

Funding deals are usually built around one lawsuit or a group of cases, and they serve two very different groups: businesses with commercial disputes and individuals waiting on injury claims. The structure changes the amount of money involved, the cost, and who qualifies.

Single-Case Funding

Single-case funding ties the investment to one specific lawsuit. The funder reviews the claim, the evidence, and the likely damages before agreeing to pay legal fees, expert witness costs, or court expenses.

If the case is lost, the plaintiff owes nothing. That is what makes these deals non-recourse.

Because all the risk sits with one outcome, funders are selective. They often look for cases with clear liability, a defendant who can actually pay, and damages large enough to cover the investment several times over.

The trade-off is cost. A funder backing one case usually asks for a larger share of the recovery than it would in a broader arrangement.

Portfolio Funding

Portfolio funding spreads money across several cases at once, usually through a law firm rather than an individual client. The firm receives capital tied to a group of matters, and repayment comes from the combined results.

This lowers risk for the funder. One weak case does not sink the deal if the others perform.

Law firms often prefer this structure for a few reasons:

• Lower pricing compared with single-case deals
• Steady cash flow to cover payroll and case costs
• Flexibility to add new matters to the pool over time

Portfolio arrangements can also cover a company’s own group of claims, not just a firm’s caseload.

Commercial And Consumer Funding

These two branches operate under different rules and serve different needs.

Commercial funding is the larger side of the market by dollar volume. Deals are negotiated case by case, and the funder generally has no say in strategy or settlement decisions.

Consumer funding moves faster and involves smaller sums. Several states regulate it directly, with rules on disclosure and rate caps that do not apply to commercial deals.

Potential Benefits For Claimants And Businesses

Litigation funding shifts the cost of a lawsuit to an outside investor, which frees up a claimant’s cash and can change how the other side approaches negotiations.

Funding Legal Costs And Operations

A funder can cover attorney fees, expert witnesses, court filing fees, document review, and other case expenses. Because most agreements are non-recourse, the claimant owes nothing if the case is lost.

For a company, this keeps legal spending off the operating budget. Instead of pulling money from payroll, equipment, or product development, the business can pursue a claim while running as usual.

Common expenses a funder may pay include:

• Lawyer fees and hourly billing
• Expert reports and testimony
• Depositions and transcripts
• E-discovery and data hosting
• Filing and appeal costs

Individual plaintiffs see a different benefit. Someone with a strong claim but limited savings can hire experienced counsel and stay in a case that might otherwise take years to resolve.

Improving Settlement Leverage

Money runs out before cases do. A defendant with deeper pockets can stretch out discovery and motions, hoping the plaintiff accepts a low offer just to end the expense.

Funding removes that pressure. When a claimant can pay for the full process, including trial, an early lowball settlement becomes easier to refuse.

Funders also perform their own review before writing a check. That vetting — of the legal theory, the damages estimate, and the defendant’s ability to pay — signals to the opposing side that a neutral party sees value in the claim.

Risks, Costs, And Ethical Considerations

Litigation funding can cover legal bills, but it comes at a price. Funders charge for the risk they take, and their involvement raises questions about who controls a case, what information must be shared, and how much of an award the client keeps.

Pricing And Recovery Dilution

Funding is not a loan with a simple interest rate. Most agreements pay the funder either a multiple of the amount invested or a percentage of the recovery, and sometimes whichever figure is higher.

Common structures include:

• Multiples that increase over time, such as 2x the invested capital in year one and 3x by year three
• Percentage of proceeds, often in the 20% to 40% range
• Hybrid caps and floors that set a minimum return for the funder

The practical effect is dilution. After legal fees, expert costs, and the funder’s return, a client’s net share of a settlement can be much smaller than expected.

Attorneys often model several outcomes before signing so the client sees the take-home number in a low, middle, and high recovery scenario.

Control, Confidentiality, And Privilege

Funding adds a third participant to what is normally a two-party relationship. That can create tension with an attorney’s duty of loyalty and the client’s right to make decisions about the case.

Most agreements state that the client keeps authority over settlement and strategy. Even so, funders may ask for budget approval rights or regular case updates, and those terms deserve close review.

Confidentiality is a related concern. Sharing work product, damages models, or case assessments with a funder during due diligence may risk waiving privilege, depending on the court.

Common protections include:

• Signing a nondisclosure agreement before diligence begins
• Limiting shared material to what the funder truly needs
• Relying on the common interest doctrine where local law supports it

Disclosure And Regulatory Requirements

Rules on disclosure vary widely. There is no single federal requirement that parties reveal funding in every case, though some judicial districts, individual judges, and state laws now require it.

Groups such as Lawyers for Civil Justice have pushed for a uniform civil rule mandating disclosure, arguing that funding can affect settlement decisions. Funders generally counter that their agreements are not relevant to the merits of a claim.

Several states have passed laws addressing consumer funding, foreign funders, or disclosure duties, and proposals continue to appear in Congress and state legislatures.

Because requirements differ by forum, counsel should confirm local rules and standing orders before filing, and keep funding documents organized in case a judge asks for them.
