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.
Subdivision (b). Since capacity to sue is governed by substantive law, subdivision (b) clearly states that proposition. This subdivision has been modified from the Federal counterpart in order to conform with present Alabama practice. It is not possible in Alabama to speak in general terms about actions by and against infants in the same breath with actions by and against incompetents. This subdivision preserves the present situation wherein the action against an incompetent who has a general guardian can be maintained against the general guardian while an action against an infant who has a general guardian will still require the appointment of a guardian ad litem. Nothing in this subdivision is to be construed to alter present practice wherein an action may be maintained against an infant in his name with a prayer in the Complaint for the appointment of a guardian ad litem.
Subdivision (d). This subdivision, setting out the mechanics for appointment of a guardian ad litem has no counterpart in the Federal Rules. But a number of states, in adapting these rules from state adoption, have thought it desirable to carry over into the rules their prior statutory provisions of the mechanics of appointment. A similar course has been followed here. The subdivision is based on the provisions as to appointment of a guardian ad litem now contained in Tit. 7, §§ 177-181, Code of Ala., which statutes will be superseded by the Rule.
Committee Comments to October 1, 1995, Amendment to Rule 17
The amendment changed the word “infant” in the rule to “minor.” All other changes are technical. No substantive change is intended.
Committee Comments to Amendment to Rule 17(a) Effective August 1, 2004
The second paragraph of Rule 17(a), which never existed in the corresponding Federal Rule, is deleted. Subrogation (e.g., when rights of subrogation arise, and the extent of those rights) is an issue of substantive, not procedural, law. Procedural issues relating to subrogation can appropriately be decided within the confines of Rules 19 and 17(a) (first paragraph), as they are in the federal courts.
Note from the reporter of decisions: The order amending Rules 4, 4.1, 4.2, 4.3, 4.4, 6(a), 7(b)(2), 17(a), 22(c), and 26(b), Alabama Rules of Civil Procedure, effective August 1, 2004, is published in that volume of Alabama Reporter that contains Alabama cases from 867 So.2d.
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.
