Text sizeJump to: (a) (b) (c) (d) (dc)

(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 that person’s own name without joining 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. The capacity of a party, including one acting in a representative capacity, to sue or be sued shall be determined by the law of this state.
(c) Minors or incompetent persons. Whenever a minor has a representative, such as a general guardian or like fiduciary, the representative may sue in the name of the minor. Whenever an incompetent person has a representative such as a general guardian or a like fiduciary, the representative may sue or defend in the name of the incompetent person. If a minor or an incompetent person does not have a duly appointed representative, that person may sue by that person’s next friend. The court shall appoint a guardian ad litem
(1) for a minor defendant, or (2) for an incompetent person not otherwise represented in an action and may make any other orders it deems proper for the protection of the minor or incompetent person. When the interest of an infant unborn or unconceived is before the court, the court may appoint a guardian ad litem for such interest. Moreover, if a case occurs not provided for in these rules in which a minor is or should be made a party defendant, or if service attempted upon any minor is incomplete under these rules, the court may direct further process to bring the minor into court or appoint a guardian ad litem for the minor without service upon the minor or upon anyone for the minor.
(d) Guardian ad litem; how chosen. Whenever a guardian ad litem shall be necessary, the court in which the action is pending shall appoint to serve in that capacity some person who is qualified to represent the minor or incompetent person in the capacity of an attorney or solicitor, and must not select or appoint any person who is related, either by blood or marriage within the fourth degree, to the plaintiff or the plaintiff’s attorney, or to the judge or clerk of the court, or who is in any manner connected with such plaintiff or such plaintiff’s attorney, or who has been suggested, nominated, or recommended by the plaintiff or the plaintiff’s attorney or any person for the plaintiff. If the guardian ad litem is to be appointed for a minor fourteen (14) years of age or over, such minor may, within thirty (30) days after perfection of service upon the minor in such cause, have the minor’s choice of a guardian ad litem to represent the minor in said cause certified by an officer authorized to take acknowledgments, but if such minor fails to nominate a guardian ad litem within the thirty- (30-) day period or before any hearing set in the action, whichever is earlier, the court shall appoint a guardian ad litem as before provided. In all cases in which a guardian ad litem is required, the court must ascertain a reasonable fee or compensation to be allowed and paid to such guardian ad litem for services rendered in such cause, to be taxed as a part of the costs in such action, and which is to be paid when collected as other costs in the action, to such guardian ad litem.
(dc) District court rule. Rule 17 applies in the district courts except that the thirty- (30-) day time period in Rule 17(d) is reduced to fourteen (14) days.

Committee Comments on 1973 Adoption

Subdivision (a). This subdivision omits the Federal Rule 17(a) which deals with statutes of the United States. This subdivision specifically provides that substitution of plaintiffs in order to bring the real party in interest before the court shall have the same effect had the action been commenced in the name of the real party in interest. This, in effect, makes the doctrine in relation back of amendments changing parties applicable to plaintiffs and is the companion to similar treatment for defendants found in Rule 15.

Plain-English Summary

Rule 17 answers two different but related questions: who gets to bring the lawsuit, and whether that person or entity is even allowed to be a party in the first place. The first question is about the real party in interest — the person or entity that holds the legal right being enforced. A suit generally has to be filed in that person’s name, though the rule carves out well-recognized exceptions for people who can sue in their own name on someone else’s behalf, such as an executor, administrator, guardian, trustee, or a party who signed a contract for another’s benefit. The point is to make sure a defendant is answering to the person who truly has a stake in the outcome, so a judgment settles the dispute once and for all and can’t be relitigated by someone else claiming the same right later.

If a case is filed in the wrong name, Rule 17 doesn’t call for automatic dismissal. Once the problem is raised, the plaintiff gets a reasonable window to fix it, whether by having the real party in interest ratify the suit, join it, or step in as a substitute. When that happens, the fix is treated as if the case had been filed correctly from day one, which can matter a great deal if a deadline like a statute of limitations has run in the meantime.

The second question, capacity, is a different concept: even the right party can be blocked from suing or being sued if the law doesn’t recognize that party as legally capable of participating in litigation. Rule 17 sends that question to state law generally, and then builds in specific mechanics for the situations most likely to come up in practice. A minor or an incompetent person can sue or defend through a representative such as a guardian, or through a next friend if no representative exists. For minors or incompetent people who don’t already have someone looking out for their interests in the case, the court must appoint a guardian ad litem, and the rule spells out how that appointment works — including a conflict-of-interest bar on picking someone connected to the plaintiff’s side, and a chance for an older minor to weigh in on who is chosen.

Frequently Asked Questions

What does it mean to sue in the name of the "real party in interest"?

It means the lawsuit has to be brought by the person or entity that holds the legal right being enforced, rather than by someone with no real stake in the claim, so the case resolves the dispute for good.

Can someone sue on my behalf without me being named as a party?

In some situations, yes. People acting in certain recognized roles, such as an executor, administrator, guardian, trustee of an express trust, or someone who contracted on your behalf, can sue in their own name without joining you as a party.

What happens if a lawsuit is filed in the wrong person’s name?

The case isn’t dismissed right away. The plaintiff gets a reasonable amount of time after the problem is raised to have the real party in interest ratify the suit, join it, or substitute in, and once that happens, it’s treated as though the suit was correctly filed from the start.

What is the difference between "real party in interest" and "capacity to sue"?

Real party in interest asks who holds the right being sued on. Capacity asks a separate question — whether that person or entity is legally recognized as able to sue or be sued at all, which for most questions is governed by state law rather than by Rule 17 itself.

How does a minor or a person who is incompetent participate in a lawsuit?

Through a representative, such as a guardian, if one already exists, or through a next friend if it doesn’t. If no one is properly representing that person’s interests, the court must appoint a guardian ad litem to protect them in the case.

Who can the court appoint as a guardian ad litem?

Someone qualified to represent the minor or incompetent person, but the court is barred from appointing anyone closely connected to the plaintiff or the plaintiff’s attorney, and a minor who is fourteen or older gets a limited opportunity to nominate their own choice.
