opt-in class

An opt-in class refers to a type of legal proceeding, often used in the context of lawsuits or class actions, where individuals must actively choose to participate. Unlike an opt-out system, where all eligible individuals are automatically included unless they refuse, in an opt-in class, potential members must explicitly consent to join. This means they are informed about the case and must take action to be part of it, which helps ensure that only those who are truly interested or affected are included in the legal process.
