Rule 7013 Federal Rules of Bankruptcy Procedure
Rule 7013 of the Federal Rules of Bankruptcy Procedure is about Counterclaim and Crossclaim. It is under Part VII (Adversary Proceedings) of the Rules.
Fed. R. Civ. P. 13 applies in an adversary proceeding. But a party sued by a trustee or debtor in possession need not state as a counterclaim any claim the party has against the debtor, the debtor’s property, or the estate, unless the claim arose after the order for relief. If, through oversight, inadvertence, or excusable neglect, a trustee or debtor in possession fails to plead a counterclaim—or when justice so requires—the court may permit the trustee or debtor in possession to:
(a) amend the pleading; or
(b) commence a new adversary proceeding or separate action.
