Justipedia explains Defense
A defense is an argument that is made on behalf of the defendant in a trial. Defendants use defenses to try to prevent the court from finding them guilty in either a criminal or civil court.
Typically, attorneys argue defenses on behalf of defendants. Defendants use defense attorneys to help them due to the latter's extensive knowledge of the law and of legal proceedings.
