A:In most class actions, you do not actually have to opt-in to be included. In fact, it is very rare that a class action lawsuit is filed by opting in. The court usually certifies class actions because there are too many members to be individually named in the lawsuit. As such, you may not need to technically “join” the case. Class members are typically notified that a complaint has been filed and may be given the option to opt-out if they do not want to participate.
