A. REAL PARTY IN INTEREST. Every action shall be prosecuted in the name of the real party in interest. An executor, administrator, guardian, 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 his own name without joining with him the party for whose benefit the action is brought. 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. Except as otherwise provided by law, any person, corporation, partnership, or unincorporated association shall have capacity to sue or be sued in 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 he may sue by his 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. ASSIGNMENT AND SUBROGATION OF CLAIMS. The assignment of claims not arising out of contract is prohibited. However, nothing in this section shall be construed to affect the law in this state as relates to the transfer of claims through subrogation.
