Class action litigation funding (often called third‑party litigation funding) is a practical way for groups of people and businesses to pursue claims that would otherwise be too costly or risky to run. In multi‑party disputes, legal fees, expert evidence, data analysis, and administration costs can add up quickly. Funding helps remove that financial barrier so claimants can focus on proving the case and obtaining a fair outcome.
Used well, class action funding can unlock access to justice against well‑resourced defendants, support better organized group cases, and make it feasible to bring complex collective proceedings such as Group Litigation Orders (GLOs) in England and Wales, opt‑out collective proceedings under the UK competition regime, and US‑style securities class actions (and similar shareholder or investor claims in other jurisdictions).
What is class action funding?
class action funding provides third‑party capital to cover the costs of pursuing a collective claim. Instead of each claimant paying legal costs upfront, a specialist funder finances key litigation expenses so the case can proceed.
Funding is most relevant where:
- Multiple claimants share common legal and factual issues (for example, the same product defect, pricing conduct, or misrepresentation).
- Collective pursuit is more efficient than running hundreds or thousands of individual claims.
- Shared costs make economic sense because expert evidence and procedural steps can be used across the group.
- Representative proceedings are possible, with one or more lead claimants coordinating strategy and acting for the wider class (subject to the specific rules of each forum).
The goal is straightforward: enable strong claims to be brought and managed effectively, even when the defendants have substantial resources and the litigation budget needs to match the complexity of the dispute.
Why class action funding is growing
Collective litigation has expanded as courts and regulators have developed frameworks that allow groups to seek remedies together, especially where the harm is widespread but individual losses may be too small to litigate alone.
Funding supports this growth because it:
- Improves access to justice by reducing or removing upfront cost barriers for claimants.
- Levels the playing field by providing the resources needed to match well‑funded defenses.
- Enables specialist evidence, such as economic models in competition cases or forensic accounting in securities matters.
- Strengthens case organization, including claimant onboarding, data capture, and communications.
Recent momentum has been particularly visible in UK competition collective proceedings following Merricks v Mastercard, which is widely viewed as a catalyst for increased filings and procedural development in the Competition Appeal Tribunal (CAT). In parallel, US securities litigation remains active, with continuing claims involving disclosure issues and an increasing focus on ESG‑related statements and risk disclosures.
Types of collective actions that funding can support
Funding can be used in multiple procedural formats. The best fit depends on the legal basis of the claim, the jurisdiction, and whether participation is opt‑in or opt‑out.
1) Group Litigation Orders (GLOs) in England and Wales
A GLO is a court‑managed structure for handling multiple related claims that raise common issues. Claims remain individual, but key questions can be coordinated so the litigation proceeds efficiently.
- Claims are typically managed through a group register.
- The court can make case management orders that apply across the group.
- Funding can support common costs, including shared experts and administration.
2) Opt‑out collective proceedings in UK competition law
The UK competition regime allows collective proceedings in the CAT, including opt‑out cases where eligible class members are included automatically (unless they opt out). These cases may be follow‑on (based on an existing infringement decision) or standalone (where infringement must be proved within the proceedings).
- Opt‑out structure can dramatically increase class size and potential impact.
- Economic evidence is often central, making funding especially valuable for expert‑heavy work.
- Collective settlement approval mechanisms support structured resolution discussions.
3) Securities class actions (US‑style) and investor claims
Securities class actions commonly involve alleged misstatements or omissions in public disclosures, accounting issues, market manipulation allegations, or other conduct affecting investors. While the precise mechanism varies by jurisdiction, the recurring theme is that many investors may have been affected by the same information event or course of conduct.
- Claims can require intensive document review, expert analysis, and damages modeling.
- Funding can support the costs required to pursue complex disclosure and causation arguments.
- In the US context, a lead plaintiff is typically appointed to represent the class.
How class action funding works: the end‑to‑end process
While details vary by funder and jurisdiction, class action funding typically follows a structured lifecycle. Well‑run funding processes are designed to test the case early, build the claimant group efficiently, and support a disciplined litigation strategy over time.
Step 1: Initial merits assessment
A funder will usually begin with an initial review to assess whether the claim is suitable for collective treatment and commercially viable to fund. This is not just about whether the claim sounds compelling; it is about whether it can be proven and managed efficiently at scale.
Typical assessment inputs include:
- Core pleadings or draft legal analysis
- Evidence summary and key documents
- Preliminary damages methodology
- Proposed forum, class definition approach, and procedural roadmap
- Counsel’s experience and resourcing plan
Step 2: Claimant book‑building (group formation)
For opt‑in structures (and often even in opt‑out contexts), a critical success factor is assembling the claimant cohort. This involves building a reliable dataset of potential class members and their losses, while keeping communications clear and consistent.
- Identify eligible claimants and define the class criteria
- Collect claim information and evidence in a standardized way
- Estimate aggregate damages across the group
- Prepare for notice, onboarding, and ongoing communications
Step 3: Funding agreement and economics
If the case passes diligence, the parties negotiate a funding agreement. This will address budget, control and consultation rights, termination provisions, and how recoveries are shared if the claim succeeds.
Economically, funders commonly receive a percentage of recoveries, often in the range of 15% to 30% of settlement or judgment proceeds. The exact percentage depends on factors such as risk, capital intensity, expected duration, and procedural complexity.
Two common approaches to allocating returns are:
- Common‑fund style outcomes, where the return is taken from the overall recovery (often subject to court oversight in relevant regimes).
- Waterfall structures, where returns are tiered (for example, the funder receives a higher percentage if the case resolves quickly or a different tier if it runs longer and requires more capital).
Step 4: Capital deployment
Once in place, funding is used to pay for the costs that most often determine whether a complex group claim can be executed effectively.
Typical funded costs include:
- Lead counsel fees and litigation expenses
- Expert witnesses (economists, accountants, technical engineers, sector specialists)
- Court fees and procedural costs
- Book‑building, class notification, and communications administration
- Settlement administration and distribution planning
Step 5: Ongoing case management and strategy alignment
Funding is not usually a “write a check and disappear” exercise. Funders often monitor progress against budget and milestones, and they can be a valuable operational partner—particularly in large, data‑heavy proceedings—while legal strategy remains with the lawyers and the claimants’ representatives within applicable professional rules.
Step 6: Resolution and distribution
Cases resolve through settlement or judgment. A key part of successful collective litigation is distributing recoveries efficiently and transparently, including calculating entitlements, processing claims, and completing any required court approvals.
What makes a claim attractive to funders?
Funders look for cases that are not only legally sound, but also suitable for collective treatment and likely to produce a recoverable outcome. While each funder has its own underwriting approach, evaluation commonly focuses on class structure, evidence, economics, and enforceability.
Core class action suitability factors
- Commonality: shared legal and factual issues that can be addressed together.
- Numerosity: a sufficiently large group to justify collective proceedings.
- Typicality: representative claims that reflect the class issues, rather than outliers.
- Adequacy: credible lead claimants and capable, experienced counsel.
Funding approval factors (commercial and practical)
- Merits strength: a well‑grounded liability theory with a strong chance of success.
- Provable, quantifiable damages: a damages model that can be supported with evidence.
- Defendant collectability: a defendant with the ability to pay, and realistic enforcement prospects.
- Procedural viability: a credible path through certification or other threshold stages.
- Quality of the legal team: demonstrated track record in collective litigation and case management.
- Timeline and budget discipline: a plan that is ambitious but realistic about duration, appeals, and cost.
Case types commonly funded: where collective actions create leverage
Funding can support many types of multi‑party litigation, particularly where losses are distributed across a large group but the underlying conduct is common.
Consumer and product claims
- Product defects and recalls
- Unfair contract terms or systemic overcharging
- Data privacy incidents affecting large numbers of individuals
Financial services mis‑selling and systemic misconduct
- Mis‑sold financial products
- Unfair fees or representations affecting a defined customer cohort
- Conduct issues with consistent documentation across the book
Competition and cartel damages
- Cartel follow‑on damages claims
- Price‑fixing and market allocation allegations
- Abuse of dominance and exclusionary conduct impacts
Securities and investor claims
- Accounting and disclosure issues
- Alleged misrepresentation or omission affecting trading decisions
- Market manipulation and insider‑related damages theories
Environmental and ESG‑linked harms
- Pollution and contamination impacts
- Human rights and supply chain responsibility allegations (where claims are legally actionable)
- Climate and ESG litigation themes, including disclosure‑related disputes in relevant jurisdictions
Typical costs covered - and why that matters
One of the biggest benefits of funding is that it can support the full operational reality of a modern group claim. Complex litigation is not just court hearings; it is project management, expert analysis, data handling, and coordinated communications.
Funding commonly covers:
- Legal fees for claimant counsel and related litigation expenses
- Expert evidence, including economic models, technical causation work, and quantum analysis
- Administrative infrastructure to handle intake, verification, and claimant communications
- Notice and distribution processes to support fair allocation of outcomes
This breadth is important because collective claims often succeed or fail based on execution: how well the case is prepared, how credible the damages model is, and how efficiently the class is managed over time.
Funding returns: common ranges and structures
In many funded class actions, the funder’s remuneration is structured as a percentage of the amounts recovered. A typical range is 15% to 30%, often shaped by the risk profile of the matter and the anticipated duration.
While every case is different, the following ranges are commonly cited in the market:
- Competition claims: often around 15% to 25%
- Consumer class actions: often around 20% to 30%
- Securities litigation: often around 18% to 28%
Return mechanics may be implemented via:
- Common‑fund approaches (particularly where courts approve or supervise deductions from recoveries).
- Waterfall structures (tiered outcomes linked to timing or risk milestones).
From a claimant perspective, the benefit is clarity: the funding cost is typically aligned to success, so the funder is incentivized to back strong cases and support them through to resolution.
Comparing GLOs, opt‑out competition actions, and securities class actions
| Feature | GLO (England & Wales) | UK Opt‑out Competition (CAT) | Securities Class Actions (US‑style) |
|---|---|---|---|
| Participation model | Typically opt‑in (claimants join the group register) | Opt‑out for defined class (unless they opt out) | Class mechanism varies by jurisdiction; often opt‑out in US federal securities context |
| Core benefit | Efficient management of common issues while preserving individual claims | Scale and impact, with centralized procedure in a specialist tribunal | Collective redress for widespread investor harm tied to disclosures or conduct |
| Evidence emphasis | Common issue trials, shared expert evidence, coordinated disclosure | Economic evidence and class‑wide impact / pass‑through analysis are often central | Disclosure record, materiality and causation arguments, expert damages models |
| Funding fit | Supports shared costs and coordinated case management | Supports expert‑heavy litigation and large‑scale class administration | Supports intensive expert work and long‑running, document‑heavy disputes |
Key success factors in funded collective litigation

- Clear decision‑making protocols for strategy, settlement posture, and communications
2) A clear liability theory and focused case narrative
- A legally coherent theory that matches the evidence available
- Defined common issues that are suitable for collective determination
- Strategic restraint, avoiding unnecessary sprawl in allegations and scope
3) A damages model that can be proven
- Quantification methods that are understandable and testable
- Data availability to support class‑wide and individual loss calculations
- Expert evidence aligned with the relevant legal tests
4) Operational excellence in claimant management
- Efficient onboarding and verification processes
- Consistent, compliant communications
- Distribution planning that is fair and scalable
Challenges funders and claimants navigate - and how to stay ahead
Collective actions offer significant upside, but they also involve procedural and practical complexities. Understanding these issues early helps teams plan effectively and protect momentum.
Certification and threshold risk
Many collective regimes involve a gateway stage (such as certification or authorization) and not every proposed class will be approved. Even after early progress, cases can face challenges to the class definition or suitability for collective treatment.
How teams stay ahead: focus on a clean class definition, credible methodology for class‑wide issues, and a strong evidentiary foundation from the outset.
Cross‑border coordination
Large disputes can involve claimants, evidence, and defendants across multiple jurisdictions. That can introduce conflicts of law questions, parallel proceedings, and increased logistical burden.
How teams stay ahead: use a coordinated forum strategy, align counsel roles across jurisdictions, and create consistent data and communications infrastructure.
Timeline uncertainty
Collective litigation can be lengthy. Appeals, procedural disputes, and complex settlement dynamics can extend timelines beyond initial expectations.
How teams stay ahead: build budgets and funding facilities that anticipate duration, establish milestone‑based planning, and maintain regular claimant communications to support engagement.
Coordination complexity within the class
Different claimant circumstances can create tension around strategy or allocation. Settlement discussions can also raise questions about fairness and distribution methodology.
How teams stay ahead: transparent governance, clear eligibility and loss methodologies, and a distribution plan designed early rather than at the end.
Recent trends shaping the market
UK competition collective proceedings: continued momentum
The UK’s opt‑out competition regime has seen growing activity, with increased attention following Merricks v Mastercard. As procedures in the CAT continue to develop, claimants and law firms are placing greater emphasis on early preparation: class definition discipline, robust expert frameworks, and strong litigation operations.
US securities and ESG‑related litigation: sustained activity
US securities litigation remains active, including claims tied to disclosure issues and market events. ESG‑related themes continue to develop, especially where statements about risk, controls, or sustainability performance are alleged to have been misleading. For well‑founded claims, funding can help sustain the expert analysis and litigation intensity these disputes demand.
Global convergence toward collective redress
Across multiple jurisdictions, legal systems have been evolving collective mechanisms in different ways. For claimants and law firms, this creates an opportunity: well‑organized cases with strong evidence can potentially be pursued with more strategic choice of forum and structure than in the past.
Getting started: practical steps for claimants and law firms
If you believe you are part of a group affected by the same conduct, early action can significantly improve outcomes. Speed matters not only for legal deadlines, but also for evidence preservation and claimant engagement.
For potential claimants
- Identify the common harm: confirm that the facts align across the group (same product, same conduct, same pricing behavior, or same disclosure event).
- Organize key evidence: contracts, statements, purchase records, correspondence, and timelines.
- Engage experienced counsel: collective litigation is highly specialized; experience can materially affect efficiency and results.
- Understand the participation model: opt‑in versus opt‑out has practical implications for what you need to do and when.
For law firms building a collective case
- Develop a crisp liability theory that can be explained simply and proved efficiently.
- Build a credible damages methodology early, including the data requirements to prove class‑wide impact.
- Plan book‑building with strong intake processes and clear claimant communications.
- Run a competitive funding process to test economics, terms, and funder capabilities.
- Select aligned partners who can support the case throughout a long timeline, including expert‑heavy phases and settlement administration.
Conclusion: funding makes collective claims possible at real scale
Class action funding can be the difference between a claim remaining theoretical and becoming actionable. By providing third‑party capital for legal fees, expert evidence, and administration, funding enables claimants to pursue collective redress through GLOs, opt‑out competition proceedings, and securities class actions in a structured, well‑resourced way.
With funders typically taking 15% to 30% of recoveries under common‑fund or waterfall structures, the model aligns investment with success and can deliver meaningful compensation and accountability where wrongdoing affects many people at once.
Given the continuing growth of UK competition filings and active securities and ESG‑linked litigation, claimants and firms should engage experienced counsel, pursue early case assessment and claimant organization, and approach funding discussions with a clear liability theory, a provable damages model, and a practical plan for certification, coordination, and timelines.
