(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; and when a statute so provides, an action for the use or benefit of another shall be brought in the name of the State of Vermont. An insurer who has paid all or part of a loss may sue in the name of the assured to whose rights it is subrogated. 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) Guardians and Other Representatives. Whenever an infant or incompetent person has a representative, such as a general guardian, conservator, or other like fiduciary, the representative may sue or defend on behalf of the infant or incompetent person. An infant or incompetent person who does not have a duly appointed representative 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. In any action in which there are or may be defendants who have been served only by publication and who have not appeared, the court may appoint an agent, guardian ad litem, or next friend to represent them.
(c) Subrogated Insurance Claims. No claim or counterclaim shall be asserted on behalf of an insurer in the name of the assured for damages resulting from alleged wrongful acts, claimed by right of subrogation or assignment, unless at least 14 days prior to asserting such claim the insurer gives notice in writing to the assured of its intention to do so. Such notice shall be served in the manner provided for service of summons in Rule 4 or by registered or certified mail, return receipt requested, with instructions to deliver to addressee only. There shall be attached to the pleading asserting such subrogation claim a copy of the notice together with either the return of the person making the service or the return receipt. If the assured or any party suing in the assured’s right desires to assert a claim arising out of the same transaction or occurrence, the assured or party shall notify the insurer or its attorney in writing within 14 days after receipt of such notice.

Plain-English Summary

Rule 17(a) requires every action to go forward in the name of the real party in interest -- the person who holds the claim. The rule then lists people who may sue in their own name without joining the person they represent: an executor, administrator, guardian, bailee, or trustee of an express trust; someone who contracted in their own name for another's benefit; a party authorized by statute; and, when a statute requires it, an action brought in the name of the State of Vermont for another's use. An insurer that has paid a loss may sue in the name of the assured to whom it is subrogated. If someone is sued or sues in the wrong name, the case is not dismissed on that ground alone -- the court allows a reasonable time after the objection for the real party in interest to ratify the suit, or to join or be substituted in, and once that happens the case proceeds as though it had been filed correctly from the start.

Section (b) protects people who cannot represent themselves in litigation. An infant or incompetent person who already has a general guardian, conservator, or similar fiduciary sues or defends through that representative. Without one, the person may proceed through a next friend or a guardian ad litem, and the court must appoint a guardian ad litem for anyone in that position who has no other representation, or make whatever other order protects that person. When a defendant has been served only by publication and has not appeared, the court may likewise appoint an agent, guardian ad litem, or next friend to represent that defendant's interests.

Section (c) adds a specific notice requirement for subrogated insurance claims. Before an insurer can assert a claim or counterclaim in the assured's name based on subrogation or assignment, it must give the assured at least 14 days' written notice of its intent, served the way a summons is served under Rule 4 or by certified mail with a signed return receipt. A copy of that notice, along with proof of service or the return receipt, must be attached to the pleading asserting the subrogated claim. If the assured wants to raise a claim of their own arising from the same transaction or occurrence, they must notify the insurer or its attorney in writing within 14 days of receiving the insurer's notice.

Frequently Asked Questions

What does "real party in interest" mean under Rule 17?

It means the action must be brought in the name of the person who holds the claim being enforced. Rule 17(a) lists people who may sue in their own name for another's benefit without joining that person, such as executors, administrators, guardians, and trustees of an express trust.

What happens if a lawsuit is filed in the wrong party's name?

It is not dismissed just for that reason. Rule 17(a) requires the court to allow a reasonable time after an objection for the real party in interest to ratify the action or to join or be substituted in, after which the case proceeds as if it had been correctly filed from the beginning.

How are minors and incompetent persons represented in a Vermont lawsuit?

If the person already has a general guardian, conservator, or similar fiduciary, that representative sues or defends on their behalf. If not, the person may proceed through a next friend or a guardian ad litem, and the court must appoint a guardian ad litem for anyone not otherwise represented.

Can an insurer sue in the name of the person it insured?

Yes. Rule 17(a) allows an insurer that has paid all or part of a loss to sue in the name of the assured to whose rights it is subrogated.

What must an insurer do before asserting a subrogated claim in the assured's name?

Under Rule 17(c), the insurer must give the assured at least 14 days' written notice of its intent to assert the claim, served like a summons under Rule 4 or by certified mail with a signed return receipt, and must attach a copy of the notice and proof of service to the pleading.
