An answer was originally a solemn assertion in opposition to some one or something, an thus generally any counter-statement or defence, a reply to a question or objection, or a correct solution of a problem. In the common law, an answer is the first pleading by a defendant, usually filed and served upon the plaintiff within a certain strict time limit after a civil complaint or criminal information or indictment has been served upon the defendant. It may have been preceded by an optional "pre-answer" motion to dismiss or demurrer; if such a motion is unsuccessful, the defendant must file an answer to the complaint or risk an adverse default judgment.
