What to Do After You Receive a Class Action Notice
By Michael J. Reiser | Last reviewed September 29, 2026
A class action notice usually arrives by mail or email with a case name, a deadline and a list of options. It is easy to set aside. Before you do, look for the dates. The choices the notice describes can decide whether you share in a recovery and whether you keep the right to bring your own claim, and most of them expire on dates the court sets. Here is what the notice must tell you and what your options are in federal court and in California state court.
Why you received a class action notice
In a federal class action certified under Rule 23(b)(3), the court must direct to class members "the best notice that is practicable under the circumstances, including individual notice to all members who can be identified through reasonable effort." Fed. R. Civ. P. 23(c)(2)(B). The notice may be sent by mail, electronic means, or other appropriate means. Id.
Settlements trigger notice too. When the parties propose a settlement, the court must direct notice in a reasonable manner to all class members who would be bound by it, if the parties show that the court will likely be able to approve the settlement and certify the class. Fed. R. Civ. P. 23(e)(1)(B).
What the notice must tell you
A federal notice in a Rule 23(b)(3) class action must state clearly and concisely, in plain, easily understood language:
- the nature of the action;
- the definition of the class certified;
- the class claims, issues, or defenses;
- that a class member may enter an appearance through an attorney;
- that the court will exclude from the class any member who requests exclusion;
- the time and manner for requesting exclusion; and
- the binding effect of a class judgment on class members.
Fed. R. Civ. P. 23(c)(2)(B).
California state courts apply a similar rule. When class members may exclude themselves, the notice must include a brief explanation of the case, a statement that the court will exclude a member who requests exclusion by a specified date, the procedure for requesting exclusion, a statement that the judgment, whether favorable or not, will bind all members who do not request exclusion, and a statement that any member who does not request exclusion may enter an appearance through counsel. Cal. R. Ct. 3.766(d).
Option 1: Do nothing and stay in the class
If you do nothing, you remain a class member, and the judgment will bind you whether or not it favors the class. Fed. R. Civ. P. 23(c)(3)(B); Cal. R. Ct. 3.766(d). If the case settles, you may need to submit a claim form by a deadline to receive a payment. Staying in the class generally means giving up the right to bring your own lawsuit on the claims the class resolves.
Option 2: Opt out of the class action
Following the exclusion procedure in the notice by the deadline removes you from the class. You will not share in any class recovery, but you keep the right to pursue your own claim. Opting out may make sense for individuals or businesses with large losses or unusual facts. Before deciding, ask a lawyer how much time remains to file an individual case.
A second chance to opt out is sometimes available. In a federal case previously certified under Rule 23(b)(3), the court may refuse to approve a settlement unless it gives class members who did not exclude themselves earlier a new opportunity to do so. Fed. R. Civ. P. 23(e)(4).
Option 3: Object to the settlement
Any class member may object to a proposed settlement that requires court approval. In federal court, the objection must state whether it applies only to the objector, to a specific subset of the class, or to the entire class, and must state the grounds for the objection with specificity. Fed. R. Civ. P. 23(e)(5)(A). Unless the court approves it after a hearing, no payment or other consideration may be provided in connection with forgoing or withdrawing an objection, or forgoing, dismissing, or abandoning an appeal from a judgment approving the settlement. Fed. R. Civ. P. 23(e)(5)(B).
A federal court may approve a settlement that would bind class members only after a hearing and only on finding that it is "fair, reasonable, and adequate." Fed. R. Civ. P. 23(e)(2).
In California state court, a class settlement requires court approval after a hearing, and the notice of the final approval hearing must explain the proposed settlement and the procedures for filing written objections and for appearing at the hearing. Cal. R. Ct. 3.769(a), (f). Before final approval, the court must inquire into the fairness of the proposed settlement. Cal. R. Ct. 3.769(g).
Option 4: Appear through your own lawyer
Both the federal rule and the California rule allow a class member to enter an appearance through counsel. Fed. R. Civ. P. 23(c)(2)(B)(iv); Cal. R. Ct. 3.766(d)(5). This option lets a class member have its own counsel follow the case while remaining in the class.
How to tell whether a notice is real
Confirm that a notice is authentic before providing personal or financial information. Look up the case on the court's docket, or contact the court clerk or the class counsel identified in the notice. Keep the notice, write down every deadline, and follow the procedures exactly. Deadlines for exclusion, objections and claims are set by court order, and late submissions may be rejected.
