Rule 7019. Required Joinder of Parties
Fed. R. Civ. P. 19 applies in an adversary proceeding. But these exceptions apply:
(a) if an entity joined as a party raises the defense that the court lacks subject-matter jurisdiction and the defense is sustained, the court must dismiss the party; and
(b) if an entity joined as a party properly and timely raises the defense of improper venue, the court must determine under 28 U.S.C. § 1412 whether to transfer to another district the entire adversary proceeding or just that part involving the joined party.
(As amended Mar. 30, 1987, eff. Aug. 1, 1987; Apr. 2, 2024, eff. Dec. 1, 2024.)
