(a) Any claim by one or more defendants against one or more plaintiffs, or against one or more codefendants, whether in the nature of setoff, recoupment, cross claim or otherwise, and whether in tort or contract, for liquidated or unliquidated damages, or for other relief, may be pleaded as a cross claim in any action, and when so pleaded shall be called a counterclaim.
     (b) The counterclaim shall be a part of the answer, and shall be designated as a counterclaim. Service of process on parties already before the court is not necessary.

  • Counterclaim: A claim that a defendant makes against a plaintiff.
  • Damages: Money paid by defendants to successful plaintiffs in civil cases to compensate the plaintiffs for their injuries.
