§ 9-11-13.Counterclaim and cross-claim

Counterclaims and cross-claims let related disputes get resolved in one lawsuit instead of several, and this section tells Georgia litigants when they must raise a counterclaim and when they may instead choose to. Subsection (a) is mandatory: a party has to state as a counterclaim any claim it has against an opposing party at the time it serves its pleading, if that claim arises from the same transaction or occurrence as the opposing party’s claim and doesn’t require parties the court can’t get jurisdiction over. Three exceptions excuse the pleader from stating it anyway — the claim is already the subject of another pending action, the opposing party sued by a process that never gave the court personal jurisdiction over the claim, or the claim falls outside the court’s jurisdiction entirely.

Subsection (b) covers the optional side: a party may plead an unrelated counterclaim against an opposing party even if it has nothing to do with the transaction underlying the opposing claim, but that permissive counterclaim is tried separately unless the parties agree otherwise. Subsection (c) confirms a counterclaim doesn’t have to match the opposing claim in kind or amount — it can exceed it, or seek an entirely different type of relief. Subsection (d) makes clear the section doesn’t expand whatever limits already exist on asserting counterclaims or credits against the state or a state officer or agency.

The remaining subsections handle timing and additional parties. A claim that matures or is acquired after the pleader’s pleading was served may be added as a counterclaim by supplemental pleading with the court’s permission, and a counterclaim omitted through oversight, inadvertence, excusable neglect, or where justice otherwise requires may be added later by amendment with leave of court. Subsection (g) lets a party plead a cross-claim against a coparty arising from the same transaction, occurrence, or property at issue in the original action or a counterclaim in it, including a claim that the coparty is or may be liable for all or part of a claim already asserted against the cross-claimant. When complete relief on a counterclaim or cross-claim requires parties beyond the original case, the court orders them brought in as defendants if jurisdiction over them can be obtained, and where the court has ordered separate trials, judgment on a counterclaim or cross-claim can be entered even if the opposing party’s own claims have been dismissed or resolved.
