Idaho Rules of Civil Procedure Rule 17(a). Real Party in Interest.
Every action shall be prosecuted in the name of the real party in interest. An executor, administrator, personal representative, guardian, conservator, bailee, trustee of an express trust, a party with whom or in whose name a contract has been made for the benefit of another, or a party authorized by statute may sue in this capacity without joining the party for whose benefit the action is brought; and when a statute of the state of Idaho so provides, an action for the use or benefit of another shall be brought in the name of the state of Idaho. No action shall be dismissed on the ground that it is not prosecuted in the name of the real party in interest until a reasonable time has been allowed after objection for ratification of commencement of the action by, or joinder or substitution of, the real party in interest; and such ratification, joinder, or substitution shall have the same effect as if the action had been commenced in the name of the real party in interest.
(Amended December 19, 1975, effective January 1, 1976.)
