Neb. Sup. Ct. R. 6-1113
COMMENTS TO § 6-1113
[1] Subpart (a) allows but does not require a party to assert any counterclaim that it has at the time it serves its responsive pleading. Subpart (b) encourages a party to assert as a counterclaim a claim that arises out of the same transaction or occurrence as the claim asserted against the party. The rule does so by precluding the party from recovering costs if it brings the claim in a subsequent action. Furthermore, depending on the subject matter of the claim, a party who brings a subsequent action may be precluded from litigating the claim by the doctrine of claim preclusion or may be barred from relitigating issues by the doctrine of issue preclusion. In short, a party should carefully evaluate the nature of a particular claim when deciding whether to assert it as a counterclaim or to make it the subject of a subsequent action.
[2] A counterclaim is stated in the party's responsive pleading. See § 6-1107(a)(3). The original version of § 6-1113(f) provided that a party could add a counterclaim by seeking leave of court to amend its pleading. The provision was deleted in 2024 because it was unnecessary. Section 6-1115(a) governs the amendment of all pleadings, including the amendment of a responsive pleading to add a counterclaim.
