IV. PARTIES

Rule 17. Parties Plaintiff and Defendant; Capacity

(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 of the United States so provides, an action for the use or benefit of another shall be brought in the name of the United States. 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.

TITLE IV. PARTIES

Rule 17. The Plaintiff and Defendant; Capacity; Public Officers

(a) Real Party in Interest.

(1) Designation in General. An action must be prosecuted in the name of the real party in interest. The following may sue in their own names without joining the person for whose benefit the action is brought:

(A) an executor;

(B) an administrator, (C) a guardian;

(D) a bailee;

(E) a trustee of an express trust;

(F) a party with whom or in whose name a contract has been made for another's benefit; and

(G) a party authorized by statute.

(2) Action in the Name of the United States for Another's Use or Benefit. When a federal statute so provides, an action for another's use or benefit must be brought in the name of the United States. (3) Joinder of the Real Party in Interest. The court may not dismiss an action for failure to prosecute in the name of the real party in interest until, after an objection, a reasonable time has been allowed for the real party in interest to ratify, join, or be substituted into the action. After ratification, joinder, or substitution, the action proceeds as if it had been originally commenced by the real party in interest.

(b) Capacity to Sue or Be Sued. The capacity of an individual, other than one acting in a representative capacity, to sue or be sued shall be determined by the law of the individual's domicile. The capacity of a corporation to sue or be sued shall be determined by the law under which it was organized. In all other cases capacity to sue or be sued shall be determined by the law of the state in which the district court is held, except (1) that a partnership or other unincorporated association, which has no such capacity by the law of such state, may sue or be sued in its common name for the purpose of enforcing for or against it a substantive right existing under the Constitution or laws of the United States, and (2) that the capacity of a receiver appointed by a court of the United States to sue or be sued in a court of the United States is governed by Title 28, U.S.C., Sections 754 and 959(a).

(b) Capacity to Sue or Be Sued. Capacity to sue or be sued is determined as follows:

(1) for an individual who is not acting in a representative
capacity, by the law of the individual's domicile;

(2) for a corporation, by the law under which it was
organized; and

(3) for all other parties, by the law of the state where the
court is located, except that:

(A) a partnership or other unincorporated association with no such capacity under that state's law may sue or be sued in its common name to enforce a substantive right existing under the United States Constitution or laws; and

(B) 28 U.S.C. §§ 754 and 959(a) govern the capacity of a receiver appointed by a United States court to sue or be sued in a United States court.

(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. 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.

17.

Rule 19. Joinder of Persons Needed for Just Adjudication

(a) Persons to Be Joined if Feasible. A person who is subject to service of process and whose joinder will not deprive the court of jurisdiction over the subject matter of the action shall be joined as a party in the action if (1) in the person's absence complete relief cannot be accorded among those already parties, or (2) the person claims an interest relating to the subject of the action and is so situated that the disposition of the action in the person's absence may (i) as a practical matter impair or impede the person's ability to protect that interest or (ii) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason of the claimed interest. If the person has not been so joined, the court shall order that the person be made a party. If the person should join as a plaintiff but refuses to do so, the person may be made a defendant, or, in a proper case, an involuntary plaintiff. If the joined party objects to venue and joinder of that party would render the venue of the action improper, that party shall be dismissed from the action.

Rule 19. Required Joinder of Parties

(a) Persons Required to Be Joined if Feasible.

(1) Required Party. A person who is subject to service of process and whose joinder will not deprive the court of subject-matter jurisdiction must be joined as a party if:

(A) in that person's absence, the court cannot accord complete relief among existing parties; or

(B) that person claims an interest relating to the subject of the action and is so situated that disposing of the action in the person's absence

may:

(i) as a practical matter impair or impede the person's ability to protect the interest; or (ii) leave an existing party subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations because of the interest.

(2) Joinder by Court Order. If a person has not been joined as required, the court must order that the person be made a party. A person who refuses to join as a plaintiff may be made either a defendant or, in a proper case, an involuntary plaintiff.

(3) Venue. If a joined party objects to venue and the joinder would make venue improper, the court must dismiss that party.

(b) Determination by Court Whenever Joinder Not Feasible. If a person as described in subdivision (a)(1)–(2) hereof cannot be made a party, the court shall determine whether in equity and good conscience the action should proceed among the parties before it, or should be dismissed, the absent person being thus regarded as indispensable. The factors to be considered by the court include: first, to what extent a judgment rendered in the person's absence might be prejudicial to the person or those already parties; second, the extent to which, by protective provisions in the judgment, by the shaping of relief, or other measures, the prejudice can be lessened or avoided; third, whether a judgment rendered in the person's absence will be adequate; fourth, whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoinder.

(b) When Joinder Is Not Feasible. If a person who is required to be joined if feasible cannot be joined, the court must determine whether, in equity and good conscience, the action should proceed among the existing parties or should be dismissed. The factors for the court to consider include:

(1) the extent to which a judgment rendered in the person's absence might prejudice that person or the existing parties;

(2) the extent to which any prejudice could be lessened or avoided by:

(A) protective provisions in the judgment;

(B) shaping the relief; or

(C) other measures;

(3) whether a judgment rendered in the person's absence would be adequate; and

(4) whether the plaintiff would have an adequate remedy if the action were dismissed for nonjoinder.
