Class period

The class period is the specific window of time that determines who qualifies for a class action or settlement. To be eligible, you generally must have been affected during these dates, such as when you purchased a product or used a service.

Class periods exist because a lawsuit covers particular conduct over a defined stretch of time. Purchases or events outside that window usually fall outside the case, even if they seem similar.

Always check the exact start and end dates on the official settlement website before assuming you qualify. The class period is one of the most common reasons a claim is accepted or denied.

Class action settlements can be worth real money if you qualify. See which ones are open right now and what you may be owed.
