Rule 13.01. Compulsory Counterclaims

    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 that is the subject matter of the opposing party's claim and does not require for its adjudication the presence of third parties over whom the court cannot acquire jurisdiction, except that such a claim need not be so stated if, at the time the action was commenced, the claim was the subject of another pending action.
