§ Rule 13 Counterclaim and Cross-Claim

Rule 13. Counterclaim and Cross-Claim

    (a) Compulsory Counterclaims.

        (1) Pleadings. Unless otherwise specifically provided by statute or unless the relief demanded in the opposing party's claim is for damage arising out of the ownership, maintenance or control of a motor vehicle by the pleader, a pleading shall state as a counterclaim any claim which at the time of serving the pleading the pleader has against any opposing party, if it arises out of the transaction or occurrence that is the subject matter of the opposing party's claim, and does not require for its adjudication the presence of third parties of whom the court cannot acquire jurisdiction. But the pleader need not state the claim if (A) at the time the action was commenced the claim was the subject of another pending action, or (B) the opposing party brought suit upon the claim by attachment or other process by which the court did not acquire jurisdiction to render a personal judgment on that claim, and the pleader is not stating any  counterclaim under this Rule 13.

        (2) Removal of Claims Not Within the Subject-Matter Jurisdiction of the District Court. If a compulsory counterclaim filed in the District Court is not within the subject-matter jurisdiction of that court, the pleader shall simultaneously file and serve notice of removal and pay the required removal fee under Rule 54A, and the action shall be removed to the Superior Court as provided in that rule.

    (b) Permissive Counterclaims. A pleading may state as a counterclaim any claim against an opposing party that is within the subject-matter jurisdiction of the court.

    (c) Counterclaim Exceeding Opposing Claim. A counterclaim may or may not diminish or defeat the recovery sought by the opposing party. It may claim relief exceeding in amount or different in kind from that sought in the pleading of the opposing party.

    (d) Counterclaim Against the State. These rules shall not be construed to enlarge beyond the limits now fixed by law the right to assert counterclaims or to claim credits against the State of Maine or an officer or agency thereof.

    (e) Counterclaim Maturing or Acquired After Pleading. A claim which either matured or was acquired by the pleader after serving a pleading may, with the permission of the court, be presented as a counterclaim by supplemental pleading.

    (f) Omitted Counterclaim. When a pleader fails to set up a counterclaim through oversight, inadvertence, or excusable neglect, or when justice requires, the pleader may by leave of court set up the counterclaim by amendment.

    (g) Cross-Claim Against Co-party. A pleading may state as a cross-claim any claim by one party against a co-party that is within the subject-matter jurisdiction of the court and arises out of the transaction or occurrence that is the subject matter either of the original action or of a counterclaim therein or relating to any property that is the subject matter of the original action. Such cross-claim may include a claim that the party against whom it is asserted is or may be liable to the cross claimant for all or part of a claim asserted in the action against the cross-claimant.

    (h) Joinder of Additional Parties. Persons other than those made parties to the original action may be made parties to a counterclaim or cross-claim in accordance with the provisions of Rules 19 and 20.

    (i) Separate Trials; Separate Judgment. If the court orders separate trials as provided in Rule 42(b), judgment on a counterclaim or cross-claim may be rendered in accordance with the terms of Rule 54(b) even if the claims of the opposing party have been dismissed or otherwise disposed of.

    (j) [Abrogated].
