Rule 17. Real party in interest--Capacity of parties--Unknown owners or heirs
(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.
(b) Capacity to Sue or Be Sued. The capacity of a party, other than one acting in a representative capacity, to sue or be sued, shall be determined by the law of this state.
(c) Infants or Incompetent Persons. Whenever an infant or incompetent person has a representative, such as a general guardian, committee, conservator, or other like fiduciary, the representative may sue or defend on behalf of the infant or incompetent person. If an infant or incompetent person does not have a duly appointed representative the person may sue by a next friend or by a guardian ad litem. The court shall appoint a guardian ad litem for an infant or incompetent person not otherwise represented in an action or shall make such other order as it deems proper for the protection of the infant or incompetent person.
(d) Unknown Owners or Heirs as Parties. In all actions or proceedings to obtain title or possession, or to remove adverse claim of title, or to quiet title, or for partition, or for sale, or for foreclosure of any incumbrance, or enforcement of any trust, or specific performance of any contract, or for any other disposition of any property, real, personal, or mixed, situated within the state of Idaho including choses in action either situated within or due or claimed to be due from persons, firms or corporations resident within the state of Idaho, persons may be made parties defendant either on the filing of the complaint, counterclaim or cross-claim, as the case may be, or at any time thereafter by amendment thereof, by the name and description of unknown owners, or unknown heirs or unknown devisees of any deceased person, or by any of such designations.
