Rule 15. Amended and supplemental pleadings

(a) Amendments. -- A party may amend the party's pleading only by leave of court or by written consent of the adverse party; leave shall be freely given when justice so requires. Wherever amendments shall be allowed at the time of trial or in close proximity thereto, adjournments shall be freely given upon motion by the adverse party. Requests for amendments shall be made in writing and become a part of the record except in the situation of an amendment requested during trial, which, if allowed, shall be entered upon the record by the judge hearing the trial. The original motion to amend shall be filed with the Court and a copy of the motion shall be served on the defendant or the defendant's attorney of record as provided in Rule 5(b).

(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 shall be treated in all respects as if they had been raised in the pleadings.

(c) Relation back of amendments. -- An amendment of a pleading relates back to the date of the original pleading when:

(1) Relation back is permitted by the law that provides the statute of limitations applicable to the action, or

(2) 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, or

(3) the amendment changes the party or the naming of the party against whom a claim is asserted if the foregoing subsection (2) is satisfied and, within the period provided by statute or these Rules for service of the summons and complaint, the party to be brought in by amendment has received such notice of the institution of the action that the party will not be prejudiced in maintaining a defense on the merits, and knew or should have known that, but for a mistake concerning the identity of the proper party, the action would have been brought against them.

(d) Supplemental pleadings. -- The Court may, upon motion of a party, on reasonable notice and such terms as are just, permit the party to serve a supplemental pleading setting forth transactions or occurrences or events which have happened since the date of the pleading sought to be supplemented. If the Court deems it advisable that the adverse party plead to the supplemental pleading, it shall so order, specifying the time therefor.
