Minn. R. Civ. P. 15.04
As amended through October 28, 2024
Upon motion of a party the court may, upon reasonable notice and upon such terms as are just, permit the party to serve a supplemental pleading setting forth transactions, occurrences, or events which have happened since the date of the pleading sought to be supplemented, whether or not the original pleading is defective in its statement of a claim for relief or of a defense. If the court deems it advisable that the adverse party plead thereto, it shall so order, specifying the time therefor.
