Will I have to testify in a class action?

The point of a class action is that a few representatives litigate for everyone. If every member could be questioned, the efficiency that justifies class treatment would disappear. In Phillips Petroleum Co. v. Shutts (1985), the Supreme Court said that unlike a defendant in a normal civil suit, an absent class-action plaintiff "is not required to do anything" and "may sit back and allow the litigation to run its course." The Court also noted that absent class members are not subject to coercive or punitive remedies.

The Federal Judicial Center, which trains federal judges, makes the same point. Its Manual for Complex Litigation, Fourth says that one of the principal advantages of class actions over mass joinder would be lost if all class members were routinely subjected to discovery, and that discovery aimed at individual class members other than named plaintiffs should be conditioned on a showing that it serves a legitimate purpose.

In practice, the evidence in consumer class actions usually comes from the company's own records (billing data, call logs, marketing materials, security audits) and from experts, not from individual customers.

Courts limit discovery from absent class members but do not forbid it altogether. When a defendant asks, judges consider whether the information is available from other sources and whether answering would force members to hire a lawyer or an expert. Approaches courts have used include:

• Short questionnaires approved by the court, sometimes limited to damages questions in a small class.
• A limited number of written questions (interrogatories) sent to a small sample of members, after a showing of need.
• Depositions of a few members, which are the hardest to get. The Manual for Complex Litigation states that deposing absent class members requires greater justification than written discovery.

Any person can also be subpoenaed as a witness under Federal Rule of Civil Procedure 45 if they have firsthand knowledge relevant to the case, for example a former employee of the company who happens to be in the class. That is about what you witnessed, not about your class membership, and it is uncommon.

Filing a claim is not testimony, but it is a signed statement. Claim forms are typically signed under penalty of perjury, and administrators may ask for documents to support larger claims. Only claim what is true. See how to file a settlement claim.

The named plaintiffs (also called class representatives) are different. They are parties to the lawsuit, so the normal discovery rules apply to them. Defendants typically depose them to test whether their claims are typical of the class and whether they can adequately represent it, which the court must find under Rule 23(a) before certifying a class.

A named plaintiff can expect to:

• Answer written questions and produce documents, such as receipts, statements, and communications with the company.
• Sit for a deposition, a recorded question-and-answer session with the company's lawyers, usually at a lawyer's office.
• Stay in touch with class counsel and approve any settlement on behalf of the class.
• Testify at trial in the rare case that goes to one.

Because of that extra work, courts may approve a service award (an incentive award) for named plaintiffs. In the Heckathorn TCPA settlement with Farmers Insurance, the named plaintiff asked the court to approve an $11,000 service award from the $1.25 million fund, according to the official settlement FAQ. Most service awards are smaller. In the Robinhood trade execution settlement, the lead plaintiff sought no more than $10,000.

If you are thinking about becoming a named plaintiff yourself, expect to commit time over several years and to share documents and answer questions under oath. Most people who contact a lawyer about a case end up as ordinary class members instead, which requires nothing more than filing a claim if the case settles. Our guides on how to start a class action and how long class actions take explain what that commitment looks like.

No. Class actions that reach a jury are rare, and most end in settlement. Settlements do involve a public court hearing, the fairness hearing, where the judge decides whether to approve the deal, but class members are not required to attend.

Settlement notices say this directly. The Heckathorn settlement FAQ, for example, answers "Do I have to come to the hearing?" with "No," explains that class counsel will answer the court's questions, and says a timely written objection will be considered even if the objector does not appear. That settlement's fairness hearing was scheduled for September 23, 2026, and its notice made clear that no class member was required to appear.

You may attend if you want to, at your own expense, and you may ask to speak if you filed an objection. See how to opt out or object.

Many injury cases that people call class actions, such as drug, medical device, or chemical exposure cases, are actually mass torts. Each injured person files an individual lawsuit, and federal cases are often consolidated in multidistrict litigation (MDL) for pretrial work. See class action vs. mass tort.

Because each plaintiff is a party with an individual claim, testimony is more likely:

• Fact sheets. Plaintiffs often complete detailed questionnaires about their medical history and use of the product.
• Depositions. Plaintiffs whose cases move forward may be deposed about their injuries.
• Bellwether trials. Judges pick a small group of cases to try first. The Federal Judicial Center's 2004 Manual for Complex Litigation says bellwether test cases should be representative of the range of cases so they produce reliable information about the rest.

Only a small number of cases are tried as bellwethers, so most mass tort plaintiffs never testify at trial. Your own lawyer prepares you if testimony is needed. Current examples include the hair relaxer cancer lawsuits and the Depo-Provera lawsuits. If you were injured and want to know whether you have a case, a free case review takes about two minutes.
