Legal Procedure

What is Complaint?

The initial document filed to start a lawsuit, setting forth the plaintiff's claims, the facts supporting them, and the relief sought.

Understanding Complaint

The complaint identifies the parties, establishes jurisdiction, states causes of action, and demands relief. It must be served on the defendant along with a summons. The defendant then has a set time to respond with an answer.
