Class Action Lawyers: Roles, Fees, and How Cases Work

Class action lawyers represent large groups of people with the same claim against the same defendant, or defend the companies those groups sue. On the plaintiff side, they work almost entirely on contingency: no fee unless the case wins or settles, and the fee itself is approved by a judge, not negotiated with any single client. On the defense side, they work to defeat class certification, narrow the class, or resolve claims on favorable terms. The work is governed by Federal Rule of Civil Procedure 23, unfolds over years, and in 2025 produced more than $70 billion in settlements across over 13,000 federal filings.¹

What Class Action Lawyers Actually Do

On the plaintiff side, the lead attorneys are called class counsel. A trial court appoints them to represent the entire class, choosing based on their track record and expertise in the relevant area of law.² Once appointed, class counsel owe legal duties to every member of the class, not just to the named plaintiffs who filed the case. That duty generally prevents them from cutting side deals for the individuals whose names appear on the complaint.³ In larger cases, a steering committee of multiple firms handles different pieces of the litigation, with lead counsel directing the work.

Class counsel represent people they have never met and who may not know the lawsuit exists. The New York City Bar Association’s Formal Opinion 2004-01 addresses this directly: class lawyers owe duties of competence, diligence, and confidentiality to all class members, even those who have not individually retained them. When the wishes of the named plaintiffs conflict with the interests of the broader class, the lawyer may act in the class’s best interests, including supporting or opposing a settlement over the named plaintiffs’ objections, so long as they disclose the situation to the court.⁴ Because absent class members cannot effectively police their own lawyer, the court fills that role by scrutinizing settlements and fee arrangements.

Securities class actions have their own selection process under the Private Securities Litigation Reform Act of 1995. The first plaintiff to file publishes notice in a national business publication within 20 days, other class members have 60 days to seek appointment as lead plaintiff, and the court appoints the “most adequate plaintiff,” presumed to be the person or group with the largest financial interest. That lead plaintiff then picks counsel, subject to court approval. To limit repeat players, the statute bars any person from serving as lead plaintiff in more than five securities class actions during any three-year period.⁵

On the defense side, lawyers focus on defeating certification, narrowing the class, or achieving favorable settlements. Their tools include motions to dismiss, challenges to expert testimony, arbitration clauses and class waivers, and forum management through removal to federal court or consolidation into multidistrict litigation. One increasingly prominent approach is trial-oriented from the start: broad early investigation, depositions of named plaintiffs, and identification of putative class members whose individual circumstances cut against commonality.⁶ Even after a class is certified, defense counsel can seek decertification at trial by surfacing individualized issues that emerge as plaintiffs try to prove every element for every class member.

Corporate defendants also work upstream of any lawsuit. Arbitration clauses with class action waivers in consumer and employment contracts push disputes into individual proceedings, an approach the Supreme Court validated in AT&T Mobility v. Concepcion (2011) and Epic Systems Corp. v. Lewis (2018). Class waivers remain, in the language of one defense firm, “routinely enforced,” though plaintiffs have responded by filing thousands of individual arbitrations simultaneously in what has come to be called mass arbitration.⁷

How Class Action Lawyers Get Paid

Plaintiff-side class action attorneys almost universally work on contingency. Their fees come out of a “common fund,” the pool of money recovered from the defendant, and the amount is approved by the court rather than negotiated with any individual client.²

Courts calculate those fees two main ways. The percentage-of-recovery method awards a share of the total settlement. The lodestar method multiplies hours worked by a reasonable hourly rate, sometimes with a multiplier for risk and complexity. Many courts use one as the primary calculation and the other as a cross-check.⁸

An empirical study of 689 common-fund cases from 1993 to 2008 found the average fee-to-recovery ratio was about 23 percent, with medians in the major federal districts running between 20 and 29 percent. The larger the recovery, the smaller the percentage tended to be. Courts approved the requested fee amount in more than 70 percent of cases.⁸ Class counsel typically request between 20 and 45 percent of the settlement fund.⁹

Recent appellate decisions have tightened scrutiny of those requests. In 2024, the Eighth Circuit found hourly rates effectively reaching $7,000 to $9,500 unreasonable in the T-Mobile data breach litigation. The Second and Third Circuits have vacated fee awards calculated against the face value of coupon settlements rather than what class members actually redeemed.⁹

The Rules Class Action Lawyers Work Under

In federal court, everything runs through Rule 23. Before a case can proceed as a class action, the lawyers must persuade the court that four prerequisites are met under Rule 23(a): the class is too large for individual suits (numerosity), members share common questions of law or fact (commonality), the named plaintiffs’ claims are representative of the group’s (typicality), and the named plaintiffs and their counsel can fairly protect everyone’s interests (adequacy of representation).¹⁰

Numerosity has no fixed threshold; some courts treat 40 members as a working benchmark and weigh factors like geographic dispersion.¹¹ Commonality demands more than surface similarity. After Wal-Mart Stores, Inc. v. Dukes (2011), courts conduct a “rigorous analysis” to make sure the shared questions can generate answers that actually drive the case.¹²

Meeting the four prerequisites is necessary but not sufficient. The class must also qualify under one of the pathways in Rule 23(b). The most common route for money-damages cases is Rule 23(b)(3), which requires that common questions “predominate” over individual ones and that a class action be the best available method for resolving the dispute.¹² Rule 23(b)(1) covers cases where separate lawsuits would create conflicting obligations for the defendant. Rule 23(b)(2) covers cases where the defendant has acted in ways that make injunctive relief appropriate for the class as a whole.

How a Case Moves Through Court

Class actions unfold across years, not months. Understanding the phases helps you know what to expect if you sign on as a named plaintiff or receive notice as an absent class member.

A case begins with a complaint that names the plaintiffs, identifies the defendant’s alleged wrongdoing, defines the proposed class, and states the legal claims. Within roughly two to four months, defendants usually respond with a motion to dismiss. If the case survives, the parties enter discovery, exchanging documents, answering written questions, and deposing witnesses. Discovery alone can take several years in complex cases.¹³

The pivotal moment is the motion for class certification, when plaintiffs ask the court to formally recognize the class. If certification is granted, the case may move toward summary judgment and, potentially, trial. Trials are rare: fewer than one percent of class actions reach that stage. Most cases settle. Settlements require preliminary and then final court approval, with a notice period in between during which class members can participate, object, or opt out. From preliminary to final approval typically takes 90 days to more than a year.¹³

Opt-Out and Opt-In Rules

How you participate depends on the type of class. In a Rule 23(b)(3) damages class, the most common kind, you are automatically included unless you affirmatively opt out. The notice must clearly explain your right to opt out, the deadline and method, your right to appear with your own attorney, and the consequences of staying in (being bound by the judgment). The opt-out window is typically 45 to 60 days from the notice date.¹⁴

Some class actions work the other way. In Fair Labor Standards Act wage and hour cases, individuals must affirmatively opt in. The notice explicitly states that participation requires an election.¹⁵ Classes certified under Rule 23(b)(1) and 23(b)(2), the mandatory and injunctive-relief pathways, generally do not offer a right to opt out, though a court may grant one at its discretion.¹⁴

Types of Cases

Class action lawyers work across nearly every sector of the economy. The most common categories:

Consumer fraud claims involving deceptive marketing, hidden fees, or product misrepresentation.¹⁶
Securities fraud cases alleging material misstatements or omissions that moved stock prices, often built on a “fraud-on-the-market” theory of reliance.¹⁷
Employment and wage disputes addressing systemic wage theft, overtime violations, employee misclassification, and workplace discrimination.¹⁶
Antitrust cases targeting price-fixing cartels or exclusionary practices.¹⁷
Product liability and mass torts involving defective drugs, medical devices, or environmental contamination.¹⁶
Data breach and privacy claims arising from security failures that expose consumer information, an area that has surged in recent years.¹⁶

Class Actions Versus Multidistrict Litigation

Class actions are sometimes confused with multidistrict litigation, and the two often overlap, but they are not the same thing. When similar lawsuits are filed in federal courts around the country, the Judicial Panel on Multidistrict Litigation can consolidate them into a single court for pretrial proceedings under 28 U.S.C. § 1407. An MDL can contain individual lawsuits, proposed class actions, or both. Unlike a class action, where a single trial resolves claims for the entire group, each case in an MDL keeps its individual identity and can be sent back to its original court for trial once shared pretrial work is complete.¹¹ In practice, most MDL cases settle before that happens, often informed by bellwether trials that give both sides a data-driven sense of case value.¹⁸

Why So Many Class Actions End Up in Federal Court

The Class Action Fairness Act of 2005 (CAFA) reshaped where large class actions are litigated by expanding federal jurisdiction. A federal court has jurisdiction if the aggregate amount in controversy exceeds $5 million, the class has more than 100 members, and any single class member is a citizen of a different state from any defendant, a standard known as “minimal diversity.”¹⁹ Any defendant can remove the case to federal court without co-defendant consent, and the usual one-year removal deadline does not apply.²⁰

CAFA carves out genuinely local disputes. Federal courts must decline jurisdiction when more than two-thirds of the class and at least one primary defendant are citizens of the state where the case was filed, the principal injuries occurred there, and no similar class action was filed in the prior three years.¹⁹ Courts may also decline when between one-third and two-thirds of the class are in-state citizens, based on discretionary factors. CAFA also reaches “mass actions” where 100 or more individual plaintiffs seek to have their monetary claims tried together.²⁰

The federal-versus-state choice matters. Federal courts sitting in diversity apply the substantive law of the forum state, which creates difficult choice-of-law problems for nationwide classes. Federal courts have become “increasingly reluctant” to certify nationwide classes when state consumer protection or products liability laws vary in material ways.²¹

Choosing a Class Action Lawyer

If you are considering bringing a case or serving as a named plaintiff, the choice of attorney matters enormously. Experience in the specific type of case is the threshold qualification. Securities fraud, employment discrimination, and product liability each demand different substantive expertise and procedural knowledge.²² Equally important is whether the firm has the resources to finance complex, multi-year litigation: a deep bench, access to expert witnesses, and the financial stability to carry expenses that may not be recouped for years.

Because class action attorneys work on contingency, ask upfront what percentage the firm will seek from any recovery and whether any costs might be charged separately. Get the fee agreement in writing. Seeking independent advice before signing is worthwhile. Communication is a real consideration too. These cases move slowly, with long stretches of discovery and procedural maneuvering, and a good attorney explains what is happening and why without hiding behind jargon. Screen for conflicts: a firm with pre-existing relationships with the opposing party may not be the right choice.²²

What Is Changing Right Now

The volume alone tells part of the story. Federal filings topped 13,000 in 2025, an average exceeding 36 new cases per day, and corporations paid more than $70 billion in class action settlements that year, the highest figure in the history of American litigation. Courts granted certification in more than 68 percent of contested motions, up from 63 percent in 2024.¹

Several current developments are worth knowing if you are involved in or considering a class action.

AI Cases

Artificial intelligence has opened new fronts in class litigation. In Bartz et al. v. Anthropic, a class of nearly half a million authors reached a $1.5 billion deal, the largest class action settlement of 2025. The court ruled that training on legally acquired books was “transformative” fair use, but downloading pirated copies from unauthorized repositories was not.²³ In Kadrey v. Meta, a different federal judge granted summary judgment for Meta on fair use grounds, calling the use “highly transformative.” Courts remain sharply divided.²⁴

Employment is another frontier. Mobley v. Workday alleges that AI-powered screening tools discriminated against applicants based on race, age, and disability. A federal court denied Workday’s motion to dismiss and conditionally certified a collective action of applicants over age 40, citing a plaintiff with a “zero percent success rate” at passing the automated screening.²³ Kistler v. Eightfold AI, filed in January 2026, alleges that an AI hiring platform operates as an unregistered consumer reporting agency, collecting personal data without disclosure or consent.²⁵

Data Breach and Privacy

Data breach class actions exceeded 1,800 filings in 2025, more than 25 percent above 2024 and over 200 percent above 2022. Plaintiffs’ attorneys are also targeting website session-replay technology, chatbots, and tracking pixels under decades-old privacy statutes to pursue statutory damages.¹

The Uninjured-Class-Member Question

Whether a damages class can include members who suffered no actual injury is one of the most consequential unresolved questions in class action law. In June 2025 the Supreme Court had the chance to resolve it in Labcorp v. Davis but dismissed the case as improvidently granted, leaving a persistent circuit split in place. Justice Kavanaugh dissented, arguing that classes “overinflated with uninjured members” force companies into costly settlements under threat of massive aggregate liability and should not be certifiable because common questions cannot predominate.²⁶ The issue remains live, and Kavanaugh’s dissent has been read as an invitation to bring the question back to the Court.²⁷

Critics argue that funders, despite describing themselves as passive investors, may contractually require settlement approval, influence counsel selection, or veto litigation decisions. In In re Pork Antitrust Litigation, a funder withheld settlement approval and prompted an attempt to substitute the funder for the plaintiff, which a federal magistrate judge blocked.²⁸ There is no uniform federal disclosure requirement, though some judges have adopted standing orders mandating disclosure. As of 2025, seven states — Arizona, Colorado, Georgia, Kansas, Montana, Oklahoma, and Tennessee — have passed legislation addressing the practice.³⁰

Enforcement Environment

The 2026 Duane Morris Class Action Review reports that the Trump administration’s enforcement policies have led to a significant reduction in systemic enforcement by agencies like the EEOC, particularly on “disparate impact” theories. As agencies pull back, private plaintiffs’ attorneys have moved in with high-stakes class actions.¹ The 2026 Carlton Fields Class Action Survey of corporate legal departments reports larger caseloads, more aggressive plaintiffs, and greater difficulty reaching settlements, with new risks concentrated in labor, consumer fraud, and data privacy.³¹
