2.07.050 Counterclaims

(a) Compulsory counterclaims. The defendant's written answer shall state as a counterclaim any claim which, at the time of the answer, the defendant has against the opposing party, if it arises out of the same act or omission that is the basis 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. Failure to state a compulsory counterclaim in writing, shall bar a subsequent suit on such claim.

(b) Permissive counterclaim. The defendant's written answer may state as a counterclaim any claim against the opposing party not arising out of the same act or omission that is the basis of the opposing party's claim.
