Idaho Rules of Civil Procedure Rule 14(a). Third Party Practice - When Defendant May Bring in Third Party.

At any time after commencement of the action a defendant as a third-party plaintiff may cause to be served a summons and complaint upon a person not a party to the action who is or may be liable to such third-party plaintiff for all or part of the plaintiff 's claim against the third party plaintiff. The third- party plaintiff need not obtain leave to make the service if the third party plaintiff files the third-party complaint not later than 10 days after serving the original answer. Otherwise the third party plaintiff must obtain leave on motion upon notice to all parties to the action. The person so served, hereinafter called the third-party defendant, shall make any defenses to the third-party plaintiff's claim as provided in Rule 12 and any counterclaims 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 any defenses as provided in Rule 12 and any counterclaims and cross-claims as provided in Rule 13. Any party may move for severance, separate trial, or dismissal of the third-party claim; and the court may direct a final judgment upon either the original claim or the third-party claim alone in accordance with the provisions of Rule 54(b). 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 the third party defendant for all or part of the claim made in the action against the third-party defendant.
