Third-party litigation funding has grown from a niche financing tool into an industry valued at roughly $15 billion globally and more than $3 billion in the United States. As that capital has moved deeper into civil litigation, a basic procedural question has become contentious: must parties tell courts and opponents who is paying for the case?

Courts and lawmakers are debating litigation funding disclosure because judges, defendants, and legislators want to know whether outside investors influence case strategy, settlement decisions, or judicial impartiality, while funders and plaintiffs argue that broad mandates expose privileged strategy and discourage legitimate financing. The result is a patchwork of rules rather than a single standard.

Some federal appellate and district courts have adopted local rules requiring automatic disclosure of TPLF arrangements or of any person holding a financial interest in the outcome, though the scope of those rules varies considerably. Meanwhile, state legislatures have pursued their own approaches, including compromise measures that drew support from both funders and their critics, and proposals for a uniform federal rule continue to draw comment from across the judicial system and the litigation finance market.

How Third-Party Litigation Funding Works

At its core, third-party litigation funding involves an outside investor supplying capital to a claimant or law firm in exchange for a share of any recovery, structured through a private contract rather than a court-supervised arrangement. The industry is valued at roughly $15 billion globally and more than $3 billion in the United States, deployed across individual cases, bundled portfolios, and law firm operations.

The Parties, Capital, and Return Structure

Three participants typically appear in a funded case: the claimant, the claimant’s lawyers, and the litigation funder that holds no direct legal interest in the dispute.

Third-party funders provide capital on a non-recourse basis. If the case fails, the claimant owes nothing; if it succeeds, the funder collects from the proceeds.

Returns are usually calculated one of three ways:

Structure	How the funder is paid
Multiple of invested capital	2x–4x the amount advanced, often escalating over time
Percentage of recovery	A fixed share of the settlement or judgment, commonly 15%–40%
Hybrid	The greater of a multiple or a percentage

Because non-party funders bear the loss risk, pricing reflects case duration, damages models, and collection prospects.

Single-Case Funding, Portfolio Funding, and Plaintiffs’ Counsel

Single-case funding attaches capital to one dispute, most often commercial claims, patent infringement suits, or international arbitrations with substantial damages exposure.

Portfolio funding spreads capital across several matters handled by the same firm. The funder’s return depends on aggregate performance, which reduces concentration risk and typically lowers the cost of capital.

Plaintiffs’ counsel are frequently the funder’s counterparty rather than the client. Contingency-fee firms use advances to cover expert witnesses, discovery costs, and payroll while awaiting resolution of cases that may run for years.

Funders also finance mass tort dockets, where capital supports case acquisition and medical record review across thousands of claims.

What Funding Agreements Commonly Address

Litigation funding agreements are negotiated documents, and their terms are the focus of much of the current disclosure debate. TPLF contracts generally specify:

• Capital commitment and draw schedule — how much is advanced and when
• Priority of payment — the order in which the funder, counsel, and claimant recover from settlements or judgments
• Control provisions — whether the funder has any say over settlement decisions, litigation strategy, or counsel selection
• Confidentiality — restrictions on revealing the funder’s identity or the agreement itself
• Termination rights — conditions allowing the funder to stop advancing capital

Most agreements state that the claimant retains settlement authority, though critics contend that capital priority terms can still influence which offers a party accepts. Some state statutes, including Kansas, now require specific representations on funder influence.

Why Disclosure Has Become a Court Management Issue

Judges who once treated funding arrangements as a private financing matter now encounter them at recusal checks, settlement conferences, discovery disputes, and cost allocation. The practical question has shifted from whether funding is permissible to how much a court needs to know to manage a case efficiently.

Assessing Financial Interests and Conflicts of Interest

Federal judges must identify parties with a financial stake in the outcome before they can evaluate their own recusal obligations. A funder holding a contingent interest in a judgment may not appear anywhere in the pleadings.

Several districts have responded with standing orders. The District of New Jersey requires disclosure of non-party funders in all civil cases, and Chief Judge Colm Connolly of the District of Delaware issued a standing order requiring identification of funders and their ownership structures.

Conflicts also run to counsel. A firm with repeat relationships with a funder may face divided loyalties that the client cannot assess, and that the court cannot evaluate, without knowing the arrangement exists.

Settlement Authority and Litigation Decisions

Court-supervised settlement conferences depend on the presence of people who can actually approve a resolution. Where a funding agreement gives the funder veto rights over settlement, or requires its consent above or below certain thresholds, a mediator may spend hours negotiating with a party that lacks final authority.

Lawyers for Civil Justice and the U.S. Chamber’s Institute for Legal Reform have built much of their Rule 26(a)(1)(A) proposal around this point, arguing that funding influences litigation and settlement decisions.

Funders and their advocates dispute the premise. They note that most agreements expressly disclaim control over litigation, and that the control narrative rests largely on hypotheticals rather than documented interference with the attorney-client relationship.

Confidential Information, Discovery, and Protective Orders

Funding due diligence typically involves sharing case assessments, damages models, and counsel’s candid evaluation of weaknesses. That exchange raises questions about waiver of privilege and work-product protection, and it produces discovery fights over whether the underlying materials are shielded.

Courts have generally distinguished between two categories:

Category	Typical treatment
Existence and identity of the funder	Increasingly subject to disclosure requirements
Financial terms and diligence memoranda	Often protected as work product or shielded by protective order

Protective orders offer a middle path. Judges can order disclosure to the court alone, or to opposing counsel under attorneys’-eyes-only terms, limiting competitive harm while resolving the management questions in front of them.

Costs, Sanctions, and Meaningful Participation in Conferences

Cost-shifting and sanctions assume a solvent party that can be held accountable. When an undercapitalized plaintiff litigates on funded terms, a defendant that prevails may find no meaningful source of recovery for taxable costs or Rule 11 sanctions.

Some courts have considered whether a funder’s financial interest supports security for costs, particularly in cases brought by shell entities.

Disclosure also affects the substance of Rule 16 conferences. Knowing whether a case is funded, and on what timeline, helps a judge assess realistic settlement windows, proportionality arguments in discovery, and whether a party’s stated resource constraints reflect its actual position.

The Case for a Uniform Federal Disclosure Rule

Proponents of mandatory disclosure argue that the current patchwork of standing orders, local rules, and state statutes produces inconsistent obligations across federal courts, and that the Federal Rules of Civil Procedure already supply a workable model in the treatment of insurance agreements.

The Proposed Amendment to the Federal Rules of Civil Procedure

The central proposal would amend Rule 26 to require parties to identify, at the outset of a case, any nonparty person or entity that has a right to receive contingent compensation from the proceeds of the litigation.

Drafts circulated to rulemakers go further than mere identification. They would require production of the funding agreement itself, subject to redaction or protective order in appropriate circumstances.

Supporters frame this as an initial disclosure obligation rather than a discovery dispute. Under that structure, disclosure would occur automatically, without motion practice, and without requiring the opposing party to first establish relevance.

The stated goal is predictability: the same obligation in the Northern District of California as in the District of Delaware.

The Role of the Advisory Committee on Civil Rules

The Advisory Committee on Civil Rules, part of the Judicial Conference’s rulemaking structure, has considered third-party funding proposals repeatedly over the past decade.

In 2024, the Committee established a dedicated subcommittee to study third-party litigation funding rather than acting on a proposal immediately. That subcommittee has gathered information on funding practices, existing local rules, and the experience of judges who have already ordered disclosure.

The process is deliberately slow. Any amendment must pass through the Advisory Committee, the Standing Committee on Rules of Practice and Procedure, the Judicial Conference, the Supreme Court, and a congressional review period.

Public comment periods allow funders, plaintiffs’ firms, and defense organizations to submit evidence before a rule is finalized.

Arguments Advanced by LCJ and ILR

Lawyers for Civil Justice (LCJ) has been the most persistent petitioner, filing successive rules proposals arguing that judges cannot manage conflicts of interest, evaluate settlement dynamics, or assess control over litigation decisions without knowing who is financing a case.

The U.S. Chamber of Commerce and its Institute for Legal Reform (ILR) press related points:

• Judges and their clerks may hold financial interests that create recusal issues involving undisclosed funders
• Foreign sources of capital may gain indirect access to sensitive discovery material
• Funding arrangements can influence who controls settlement authority in aggregate litigation

Both groups contend that transparency is procedural rather than substantive, and does not require regulating funding terms themselves.

Comparison With Existing Insurance Disclosures

The comparison most often invoked is Rule 26(a)(1)(A)(iv), which requires a party to make available any insurance agreement under which an insurer may be liable to satisfy a judgment.

Feature	Insurance agreements	Funding agreements
Automatic disclosure	Required under Rule 26	Varies by court
Function	Pays a judgment	Finances the claim
Obligation to fund	Contractual duty	Typically non-recourse

Advocates argue the symmetry is obvious: if defendants must reveal who stands behind their potential liability, plaintiffs should reveal who stands to profit from recovery.

Critics respond that the analogy is imperfect, because insurers assume defense obligations and payment duties that passive investors do not.

The Case Against Automatic Disclosure

Funders, plaintiffs’ attorneys, and several consumer advocacy groups argue that blanket disclosure mandates solve a problem that has not been demonstrated, while imposing real costs on claimants who lack the resources of institutional defendants. Their objections center on access to justice, discovery burdens, protection of privileged material, and the ethical rules that already govern the attorney-client relationship.

Access to Justice and the Value of Litigation Finance

Litigation finance allows individual plaintiffs, small businesses, and class members to pursue claims against opponents with far deeper reserves. Without it, many meritorious cases settle early or never get filed.

Opponents of automatic disclosure contend that mandatory reporting deters funders from backing smaller matters, since exposure of their involvement invites collateral attacks unrelated to the merits.

They also point to an asymmetry argument raised in reverse. Defendants often argue that Federal Rule 26(a)(1)(A)(iv) requires insurance disclosure, so funding should follow. Funders respond that insurance creates a duty to indemnify and defend, while a funding agreement creates no comparable obligation and does not pay a judgment against the funded party.

Concerns About Fishing Expeditions and Litigation Cost

A recurring objection is that funding agreements become a gateway to satellite litigation. Once disclosure is automatic, defendants may seek deposition testimony from funders, communications about case valuation, and internal underwriting analyses.

That expands discovery in ways that have little bearing on liability or damages.

Critics identify several predictable consequences:

• Motion practice multiplies over the scope of what must be produced beyond the existence of an agreement
• Costs shift onto claimants, who bear the expense of litigating a collateral issue
• Settlement leverage changes, because a defendant who learns a plaintiff’s funding is nearly exhausted may simply wait
• Delay accumulates in cases where the funding relationship was never contested

The counterargument to a broad rule is narrower relief: disclosure of the funder’s identity for conflicts screening, submitted in camera to the court rather than to opposing counsel.

Privilege, Work Product, and Confidential Commercial Terms

Funding agreements are typically negotiated after counsel has assessed the claim, and the diligence materials exchanged often reflect attorney mental impressions about strengths, weaknesses, and likely recovery. That is classic work product under Rule 26(b)(3).

Most courts applying the common-interest doctrine have held that sharing such analysis with a funder under a nondisclosure agreement does not waive protection. Automatic disclosure rules that reach beyond the fact of funding risk eroding that position.

There is also a commercial dimension. Pricing structures, return multiples, and portfolio terms are proprietary to third-party funders, and compelled production hands competitors and repeat-player defendants a view into how capital is deployed.

Existing Ethical Rules and Limits on Funder Control

The rules of professional conduct already address the concern that animates most disclosure proposals. Model Rule 1.8(f) bars a lawyer from accepting compensation from a third party unless the client consents and the arrangement does not interfere with independent professional judgment.

Model Rule 5.4(c) prohibits a person who pays for legal services from directing the lawyer’s judgment, and Rule 1.2 reserves settlement authority to the client.

Standard funding agreements reflect these constraints. Most expressly disclaim any control over litigation strategy, counsel selection, or settlement decisions, leaving those choices with the client.

From this perspective, the argument runs, the remedy for a funder that oversteps is a bar complaint or a motion in the individual case, not a rule applied to every funded matter regardless of whether control was ever exercised.

The Patchwork of Court Orders, Local Rules, and State Laws

No single rule governs whether a party must reveal that a third party is financing its case. Instead, obligations depend on the courthouse, the docket type, and increasingly the state legislature.

Federal Court Approaches to Funding Disclosure

Federal courts have moved unevenly. The District of New Jersey wrote disclosure into Local Civil Rule 7.1.1 in 2021, requiring parties to identify non-parties funding litigation on a contingent basis and preserving the court’s discretion to order further discovery when a funder may be influencing litigation decisions.

MDL judges have imposed similar duties by standing order, including in the 3M combat earplug proceedings.

Other districts decline broad funding discovery, treating litigation funding agreements as irrelevant to the merits and protected by work-product doctrine.

The Advisory Committee on Civil Rules has a subcommittee studying whether an amendment to Rule 26(a)(1)(A) should replace this patchwork with a uniform initial-disclosure obligation.

The Northern District of California and Interested-Party Certifications

The Northern District of California took an early step in 2017 by amending Civil Local Rule 3-15. Its standing order for civil cases requires that, in proposed class, collective, or representative actions, parties disclose any person or entity funding the litigation in exchange for a contingent financial interest.

The disclosure is narrow. Parties identify the funder, not the terms of the agreement, and the requirement attaches to aggregate litigation rather than every civil case.

That model has influenced other courts because it borrows the familiar mechanics of interested-party certifications used for recusal screening.

Patent Litigation as a Testing Ground

Patent litigation has produced the most detailed orders. Since April 2022, Chief Judge Colm Connolly of the District of Delaware has required parties to identify third-party funders, disclose whether the funder’s approval is needed for litigation or settlement decisions, and describe the funder’s financial interest.

The order has generated contested proceedings over ownership of plaintiff entities and the real parties in interest behind assertion campaigns.

Delaware’s approach reflects a specific concern: shell entities asserting patents while the economic stake, and sometimes control, sits elsewhere.

State-Level Requirements and the GAO’s Market Context

States have legislated where federal rulemaking has stalled.

State	Focus of disclosure requirement
Wisconsin (2018)	First state to require production of funding agreements in discovery
West Virginia (2019)	Consumer legal funding registration and disclosure
Montana (2023)	Discoverability of funding agreements without further showing
Indiana, Louisiana (2024)	Emphasis on foreign funders and sovereign wealth involvement
Georgia, Kansas (2025)	Registration plus disclosure in civil litigation

Federal legislation, including the Litigation Funding Transparency Act, would extend disclosure to class actions and MDLs.

Context comes from the GAO’s December 2022 report, which examined third-party litigation funding and found limited public data on agreement terms and volume, with no consistent reporting framework across courts. Industry estimates now place U.S. assets under management in the range of $15 billion to $25 billion, depending on methodology.

What Parties and Counsel Should Evaluate Going Forward

Because disclosure standards now vary by court and by state, funded litigants and their lawyers face practical decisions at contract signing, during discovery, and at every settlement discussion. The items below address contract review, control provisions, procedural readiness, and the pace of rulemaking.

Reviewing Funding Terms Before Filing or Accepting Funds

Counsel should read TPLF contracts with the assumption that a judge may eventually review them, in whole or in redacted form.

Key provisions to examine include:

• Returns and waterfall — the funder’s multiple, priority relative to attorney fees, and treatment of appeals
• Consent rights — any requirement that the funder approve settlement, counsel changes, or budget increases
• Information rights — the scope, frequency, and format of reporting to the funder
• Termination — what happens to the funder’s claim if it withdraws mid-case
• Confidentiality carve-outs — whether the agreement permits disclosure required by court order or statute

Plaintiffs’ counsel should also confirm that fee-sharing terms comply with the ethics rules of each jurisdiction where the case may be filed.

Preserving Client Control Over Settlement and Strategy

The strongest response to control-based criticism of litigation funders is a funding agreement that leaves litigation and settlement decisions with the client.

Language stating that the funder has no right to direct strategy, select or replace counsel, or accept or reject offers serves two purposes. It protects the attorney-client relationship, and it supplies a concrete answer when opposing counsel argues that a nonparty is steering the case.

Counsel should document the client’s independent authority in the engagement letter as well, not only in the funding contract.

Where a funder holds even limited consent rights, lawyers should consider how those rights will be described if a court asks — and whether the client understands them before settlements are negotiated.

Preparing for Disclosure Requests and Case Management Orders

Funded parties should expect the question early. Standing orders in several federal districts, local rules, and now statutes in a growing number of states require identification of funding sources at or near the outset of a case.

Practical steps:

Stage	Action
Pre-filing	Confirm the forum’s standing orders and local rules on funding disclosure
Initial disclosures	Determine whether Rule 26(a)(1)(A) or a local variant reaches the agreement
Case management conference	Be ready to identify the funder and propose a protective order for financial terms
Discovery	Prepare objections grounded in relevance, work product, and proportionality

Counsel should also decide in advance whether limited voluntary disclosure — the funder’s identity and confirmation that it lacks control rights — is preferable to a contested motion.

Monitoring Rulemaking and Legislative Developments

The rules are still moving. The Federal Civil Rules Advisory Committee continues to weigh proposals to amend the Federal Rules of Civil Procedure, including the joint submission from the U.S. Chamber Institute for Legal Reform and Lawyers for Civil Justice seeking a uniform Rule 26 disclosure obligation.

Congress has also seen bills addressing funding transparency, and state legislatures have moved faster than the federal system, with several enacting disclosure and registration requirements.

Firms with multistate dockets should track these changes by jurisdiction, since a single funding agreement may face different treatment in different courts. Portfolio funders and repeat players in mass tort and patent litigation face the most exposure to inconsistent standards.
