Rule 13.Counterclaim and cross-claim

Rule 13 sorts claims a defending party might have against the other side into two categories. A compulsory counterclaim, under section (A), is one that arises out of the same transaction or occurrence as the opposing party’s claim and does not require joining someone the court cannot reach — a claim like that generally has to be raised in this lawsuit or it is lost as a basis for a later, separate suit. The rule carves out two exceptions: a claim already the subject of another pending action, and a claim the pleader is not required to raise because the opposing party sued using a process, such as attachment, that never gave the court authority to enter a personal judgment on that claim. A permissive counterclaim, under section (B), is any other claim against the opposing party, unrelated to the transaction or occurrence at issue, and a party can choose whether to raise it now or save it for later.

Several sections round out how counterclaims work in practice. A counterclaim does not have to offset or defeat the opposing claim — it can seek more money or a different kind of relief entirely. The rule does not expand any existing right to sue the state. A claim that matures or is acquired after the pleading was served can be added later, with the court’s permission, and a not-yet-due claim can be asserted against an insolvent opposing party or that party’s representative if the insolvency would otherwise impair recovery. If a counterclaim is left out of the pleading through oversight, inadvertence, excusable neglect, or because justice requires it, the court may allow it to be added by amendment. A cross-claim, under section (G), works differently — it is a claim by one party against a co-party, such as one codefendant against another, rather than against the opposing side, and other parties can be joined into a counterclaim or cross-claim under Indiana’s joinder rules.

The remaining sections handle specialized situations. Section (I) lets a court order a separate trial of a counterclaim or cross-claim and enter judgment on it even if the other claims in the case have been resolved, weighing factors like whether the cross-claim shares a transaction, property, or contract with the original action. Section (J) preserves certain counterclaims that would otherwise be barred by the statute of limitations or another discharge, to the extent they would offset the opposing claim or relate to payment or security for it. Sections (K) and (L) address counterclaims involving transferees, successors such as guardians or estate representatives, and sureties, and make clear that counterclaims and cross-claims remain subject to substantive law limits — for example, rules against a creditor gaining an unfair priority through a claim assigned around an insolvency proceeding. Section (M) allows a court to order satisfaction of a judgment, or credits against it, based on a qualifying counterclaim.
