A lawsuit is a proceeding by one or more parties (the plaintiff or claimant) against one or more parties (the defendant) in a civil court of law. The archaic term "suit in law" is found in only a small number of laws still in effect today. The term "lawsuit" is used with respect to a civil action brought by a plaintiff (a party who claims to have incurred loss as a result of a defendant's actions) who requests a legal remedy or equitable remedy from a court. The defendant is required to respond to the plaintiff's complaint or else risk default judgment. If the plaintiff is successful, judgment is entered in favor of the plaintiff, and the court may impose the legal or equitable remedies available against the defendant (respondent). A variety of court orders may be issued in connection with or as part of the judgment to enforce a right, award damages or restitution, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes.
A lawsuit may involve resolution of disputes involving issues of private law between individuals, business entities or non-profit organizations. A lawsuit may also involve issues of public law in the sense that the state is treated as if it were a private party in a civil case, either as a plaintiff with a civil cause of action to enforce certain laws or as a defendant in actions contesting the legality of the state's laws or seeking monetary damages for injuries caused by agents of the state.
