It's about a cause of action

Statement of claim (Complaint):
In the law, a cause of action (sometimes called a claim) is a set of facts sufficient to justify a right to sue to obtain money, property, or the enforcement of a right against another party. The legal document which carries a claim is often called a Statement of Claim in English law, or a Complaint in U.S. federal practice and in many U.S. states. It can be any communication notifying the party to whom it is addressed of an alleged fault which resulted in damages from which it originates, often expressed in amount of money the receiving party should pay/reimburse.
