Rule 15.Amended and supplemental pleadings.

Last amended October 1, 1995 · Last verified July 6, 2026

In one sentenceRule 15 governs when and how a party can change a pleading after filing it, letting amendments happen freely early in a case and by court permission later, while also allowing a late amendment to count, for statute-of-limitations purposes, as if it had been filed on the original date.

(a) Amendments. Unless a court has ordered otherwise, a party may amend a pleading without leave of court, but subject to disallowance on the court’s own motion or a motion to strike of an adverse party, at any time more than forty- two (42) days before the first setting of the case for trial, and such amendment shall be freely allowed when justice so requires. Thereafter, a party may amend a pleading only by leave of court, and leave shall be given only upon a showing of good cause. A party shall plead in response to an amended pleading within the time remaining for a response to the original pleading or within ten (10) days after service of the amended pleading, whichever period may be longer, unless the court orders otherwise.
(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. 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 subserved thereby 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. An amendment shall not be refused under subdivision (a) and (b) of this rule solely because it adds a claim or defense, changes a claim or defense, or works a complete change in parties. The Court is to be liberal in granting permission to amend when justice so requires.
(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, except as may be otherwise provided in Rule 13(c) for counterclaims maturing or acquired after pleading, or
(3) the amendment, other than one naming a party under the party’s true name after having been initially sued under a fictitious name, changes the party or the naming of the party against whom a claim is asserted if the foregoing provision (2) is satisfied and, within the applicable period of limitations or one hundred twenty (120) days of the commencement of the action, whichever comes later, the party to be brought in by amendment (A) 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 (B) knew or should have known that, but for a mistake concerning the identity of the proper party, the action would have been brought against the party, or
(4) relation back is permitted by principles applicable to fictitious party practice pursuant to Rule 9(h).
(d) Supplemental pleadings. 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 or occurrences or events which 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 shall so order, specifying the time therefor.
(dc) District court rule. Rule 15 applies in the district courts except that the ten- (10-) day time limit in Rule 15(a) is reduced to seven (7) days.

Committee Comments

Committee Comments on 1973 Adoption

Under Rule 15(a) and (b) the test as to whether amendment is proper will be functional, rather than, as under present Alabama law, conceptual. Under the rule it will be entirely irrelevant that a proposed amendment changes the cause of action or the theory of the case or that it states a claim arising out of a transaction different from that originally sued on or that it caused a change in parties. International Ladies’ Garment Workers’ Union v. Donnelly Garment Co., 121 F.2d 561 (8th Cir.1941); Technical Tape Corp. v. Minnesota Mining & Manufacturing Co., 200 F.2d 876 (2d Cir.1952); Naamloze Vennootschap Suikerfabriek “Wono-Aseh” v. Chase National Bank, 12 F.R.D. 261 (S.D.N.Y.1952); Colstad v. Levine, 243 Minn. 279, 285, 67 N.W.2d 648, 653 (1954); 6 Cyc.Fed.Proc. §§ 18.18, 18.19 (3d ed. 1951). The rule, instead, is that amendments are to be allowed “freely … when justice so requires.” Normally, an amendment should be denied only if the amendment would cause actual prejudice to the adverse party. 6 Wright & Miller, Federal Practice & Procedure, Civil, § 1484 (1971). Until a responsive pleading has been served or, if no such pleading is permitted and the action is not yet on the calendar, for 30 days, the party may amend as a matter of course. Thereafter amendment can be only on leave of court and requires a written motion and notice to all parties.

Plain-English Summary

Lawsuits evolve as facts come to light, and Rule 15 gives parties room to keep their pleadings current. More than 42 days before the first trial setting, a party may amend a pleading without asking the court’s permission, though the court can still disallow it on its own initiative or if the opposing side moves to strike. Closer to trial, permission is required, and the party seeking to amend must show good cause — a shift meant to keep late amendments from disrupting a trial date without derailing changes that are truly necessary.

Rule 15 also lets pleadings catch up to what happened at trial. If both sides try an issue that was not raised in the pleadings — whether by agreement or by not objecting to evidence on that issue — the rule treats the pleadings as if that issue had been there all along. Even when a party objects that evidence strays beyond the pleadings, a court can still allow the pleadings to be amended on the spot, unless the objecting side can show real prejudice, and even then a continuance can often cure the problem rather than shutting the evidence out entirely.

The rule’s relation-back provisions solve a timing problem: an amendment filed after a statute of limitations has run can still succeed if it merely adds detail to conduct or events already described in the original pleading, because the opposing party had fair notice of the dispute from the start. Relation back can even reach an amendment that changes who is being sued, provided the new party got timely notice of the case and knew, or should have known, that a mistake in identity was the only reason it had not already been named. Alabama’s fictitious-party practice offers a related but separate path: a plaintiff who truly does not know a defendant’s identity can sue a fictitious name and later substitute the real one once diligent investigation turns up who it is.

Finally, Rule 15 allows supplemental pleadings, which are different from amendments because they add matters that happened after the original pleading was filed rather than correcting or expanding what was already alleged. A party needs the court’s permission to file one, and the court can attach reasonable conditions and notice requirements to make sure the process stays fair to everyone involved.

Frequently Asked Questions

Can I amend my pleading without asking the court?

Yes, if the amendment is filed more than 42 days before the first trial setting. The court can still disallow it on its own motion or if the opposing party moves to strike, but it does not require advance permission.

What happens if I want to amend closer to trial?

You need the court’s leave, and the court will grant it only upon a showing of good cause.

Can an amendment filed after the statute of limitations has run still be allowed?

Yes, if it relates back — meaning the new claim or defense grew out of the same conduct, transaction, or occurrence already described in the original pleading, or otherwise satisfies the rule’s relation-back requirements.

Can an amendment change who is being sued after the limitations period has run?

Yes, but only if the new party received timely notice of the action and knew, or should have known, that a mistake about identity was the only reason it had not been named originally.

What is the difference between an amended pleading and a supplemental pleading?

An amendment corrects or adds to what was already true when the original pleading was filed. A supplemental pleading adds transactions, occurrences, or events that happened after that filing, and it always requires the court’s permission.
