As amended through June 26, 2024
Rule 15 - Amended and Supplemental Pleadings(a)Amendments. A party may amend the party's pleading once as a matter of course at any time before a responsive pleading is served or, if the pleading is one to which no responsive pleading is permitted and the action has not been placed upon the trial calendar, the party may so amend it at any time within 21 days after it is served. Otherwise, a party may amend the party's pleading only by leave of court or by written consent of the adverse party; leave must be freely given when justice so requires. A party must plead in response to an amended pleading within the time remaining for response to the original pleading or within 14 days after service of the amended pleading, whichever period may be the longer, unless the court otherwise orders.(b)Amendments to Conform to the Evidence. When issues not raised by the pleadings are tried by express or implied consent of the parties, they must be treated in all respects as if they had been raised in the pleadings. Such amendment of the pleadings as may be necessary to cause them to conform to the evidence and to raise these issues may be made upon motion of any party at any time, even after judgment, but failure so to amend does not affect the result of the trial of these issues. If evidence is objected to at the trial on the ground that it is not within the issues made by the pleadings, the court may allow the pleadings to be amended and shall do so freely when the presentation of the merits of the action will be aided and the objecting party fails to satisfy the court that the admission of such evidence would prejudice the party in maintaining the party's action or defense upon the merits. The court may grant a continuance to enable the objecting party to meet such evidence.(c)Relation Back of Amendments.(1) Whenever the claim or defense asserted in the amended pleading arose out of the conduct, transaction, or occurrence set forth or attempted to be set forth in the original pleading, the amendment relates back to the date of the original pleading.(2) Whenever the amendment changes a party or the naming of a party against whom a claim is asserted, the amendment relates back to the date of the original pleading if Rule 15(c)(1) is satisfied and if, within the period provided by Rule 4(e) for serving the summons and complaint, the party to be brought in by amendment received such notice of the action that it will not be prejudiced in defending on the merits and knew or should have known that the action would have been brought against it, but for a mistake concerning the proper party's identity.(d)Supplemental Pleadings. Upon motion of a party the court may, on reasonable notice and such terms as are just, permit the party to serve a supplemental pleading setting forth transactions or occurrences or events that have happened since the date of the pleading sought to be supplemented. Permission may be granted even though the original pleading is defective in its statement of a claim for relief or defense. If the court deems it advisable that the adverse party plead to the supplemental pleading, it must so order, specifying the time therefor.Nev. Justice. Ct. R. Civ. P. 15
