In the law, a cause of action 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 term also refers to the legal theory upon which a plaintiff brings suit (such as breach of contract, battery, or false imprisonment). 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, often expressed in amount of money the receiving party should pay/reimburse.
