Rule 14 Third-Party Practice

Chapter III: Pleadings and Motions

(a) When Defendant May Bring in Third Party. A defending party may cause a summons and complaint to be served upon a person not a party to the action who is or may be liable to him for all or part of the plaintiff’s claim against him. But, the third-party plaintiff must, by motion, obtain the court’s leave upon good cause shown if it files the third- party complaint more than 14 days after serving its original answer. The person served with the summons and third-party complaint, hereinafter called the third-party defendant, shall make his defenses to the third-party plaintiff’s claim as provided in Rule 12 and his counter-claims against the third-party plaintiff and cross-claims against other third-party defendants as provided in Rule 13. The third-party defendant may assert against the plaintiff any defenses which the third-party plaintiff has to the plaintiff’s claim. The third-party defendant may also assert any claim against the plaintiff arising out of the transaction or occurrence that is the subject matter of the plaintiff’s claim against the third-party plaintiff. The plaintiff may assert any claim against the third-party defendant arising out of the transaction or occurrence that is the subject matter of the plaintiff’s claim against the third-party plaintiff and the third-party defendant thereupon shall assert his defenses as provided in Rule 12 and his counter-claims and cross-claims as provided in Rule 13. Any party may move to strike the third-party claim, or for its severance or separate trial. A third-party defendant may proceed under this rule against any person not a party to the action who is or may be liable to him for all or part of the claim made in the action against the third-party defendant.

(b) When Plaintiff May Bring in Third Party. When a counter-claim is asserted against a plaintiff, he may cause a third party to be brought in under circumstances which under this rule would entitle a defendant to do so.

(c) [Admiralty and Maritime Claims] [Omitted].
