(a) Definition. A counterclaim asserts that the plaintiff owes something to the defendant. The defendant may file a counterclaim against the plaintiff that is based on the same event described in the plaintiff's complaint or based on a different event.

(b) Filing a Counterclaim. A counterclaim must be filed within 20 days of service of the summons, complaint, and notice. The amount of the counterclaim must be $3,500 or less. If the counterclaim exceeds the jurisdictional limit the court must transfer the case to the civil division of the justice court. A counterclaim that is more than $10,000 will result in a transfer of the case to the superior court.
