(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; and leave shall be freely given when justice so requires. A party shall 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 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.
(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 condition of paragraph (2) of this subdivision is satisfied and, within the period provided by Rule 3 for service of the summons and complaint, 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.
The delivery or mailing of process to the Attorney General satisfies the requirement of subparagraphs (A) and (B) of this paragraph (3) with respect to the State of Vermont or any agency or officer thereof to be brought into the action as a defendant.
(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.

Notes

Reporter’s Notes—2018 Amendment: Rule 15(a) is amended to extend its 10- and 20-day time periods to 14 and 21 days consistent with the simultaneous “day is a day” amendments to V.R.C.P. 6.

Reporter’s Notes—1995 Amendment: Rule 15(c) is amended for conformity with a 1991 amendment of Federal Rule 15(c). The reasons for the amendment are those given in the federal Advisory Committee’s Note: The rule has been revised to prevent parties against whom claims are made from taking unjust advantage of otherwise inconsequential pleading errors to sustain a limitations defense. Paragraph (c)(1). This provision is new. It is intended to make it clear that the rule does not apply to preclude any relation back that may be permitted under the applicable limitations law . . . . Whatever may be the controlling body of limitations law, if that law affords a more forgiving principle of relation back than the one provided in this rule, it should be available to save the claim . . . . If Schiavone v. Fortune, 106 S. Ct. 2379 (1986) implies the contrary, this paragraph is intended to make a material change in the rule. Paragraph (c)(3). This paragraph has been revised to change the result in Schiavone v. Fortune, supra, with respect to the problem of a misnamed defendant. An intended defendant who is notified of an action within the period allowed by [V.R.C.P. 3] for service of a summons and complaint may not under the revised rule defeat the action on account of a defect in the pleading with respect to the defendant’s name, provided that the requirements of clauses (A) and (B) have been met. If the notice requirement is met within the [V.R.C.P. 3] period, a complaint may be amended at any time to correct a formal defect such as a misnomer or misidentification. On the basis of the text of the former rule, the Court reached a result in Schiavone v. Fortune that was inconsistent with the liberal pleading practices secured by Rule 8 . . . . New V.R.C.P. 15(c)(3) similarly recognizes that liberal pleading and amendment procedures are a longstanding feature of Vermont practice. The rule would change the interpretation of former Rule 15(c) announced in Bashara v. Corliss, 161 Vt. 1, 632 A.2d 30 (1993). In that case, the Court relied on Schiavone v. Fortune, supra, to hold that an amended complaint substituting the defendant’s first name for that of his father did not relate back where the amended complaint was filed and served after the statute of limitations had run but within the 60-day period provided by Rule 3 for service. Assuming that Rules 15(c)(3)(A), (B), are satisfied by service on the Commissioner of Motor Vehicles under 12 V.S.A. § 892 in a situation where the complaint alleged conduct attributable only to the true defendant, the amended complaint in such a case would relate back. Cf. Bashara v. Corliss, 161 Vt. at 5-7, 632 A.2d at 32-34 (Morse, J., dissenting). The final paragraph of the amended rule adapts the final paragraph of former Rule 15(c) to the new provisions.

Reporter’s Notes: This rule is virtually identical to Federal Rule 15 and is the substantial equivalent of previous Vermont practice. Rule 15(a) is similar in effect to the provisions of 12 V.S.A. §§ 1034, 1132 (now superseded); former Chancery Rules 11, 29; and former County Court Rules 13, 14.5, 14.6. The statement in the federal rule that “leave [to amend] shall be freely given when justice so requires” is in accord with prior Vermont practice. See City Electrical Service & Equipment Co. v. Estey Organ Co., 116 Vt. 435, 77 A.2d 835 (1951). Although the rule is silent on the point, the federal courts have recognized that the court’s discretion to grant or deny amendment includes the power to grant it subject to conditions such as the imposition of costs. See 1A Barron & Holtzoff, Federal Practice and Procedure § 445 (Wright ed. 1961). The provision of 12 V.S.A. § 1034 for free amendment before hearing on a motion to dismiss is broadened by Rule 15, under which the federal courts have permitted amendment until the entry of judgment on the motion. See 1A Barron & Holtzoff § 443. Rule 15(b), permitting amendment to conform to the evidence even after judgment when issues not within the pleadings are tried without objection, is consistent with prior Vermont practice. See Brassard Bros., Inc. v. Barre Town Zoning Board, 128 Vt. 416, 264 A.2d 814 (1970). So also is the provision of the subdivision for amendment on objection at the trial in the absence of prejudice to defendant, with a continuance if necessary. See Congdon v. Torrey, 95 Vt. 38, 112 A. 202 (1921); former County Court Rule 14.6. Note that under Rule 15(b) amendment may be allowed after trial of the issues without regard to germaneness of the amendment to the former pleading. Amendment may be allowed at the trial over objection “when the presentation of the merits of the action will be subserved thereby” and there is no prejudice to defendant. The rule thus states a more liberal and pragmatic test than that previously followed in Vermont, where, although the term is defined broadly, the amendment must not state “a new cause of action.” See City Electrical Service & Equipment Co. v. Estey Organ Co., supra. Rule 15(c) imposes a restriction upon amendments under Rule 15(a) that is also less onerous than prior Vermont practice. An amendment that does not arise out of “the conduct, transaction, or occurrence” set forth in the original pleading will be barred if the statute of limitations has run between the date of the pleading and that of the amendment, because such an amendment does not “relate back” to the date of the original pleading. An amendment that does arise out of the same conduct, transaction, or occurrence is not barred. The doctrine of relation back was previously recognized in Vermont practice. See Dana v. McClure, 39 Vt. 197 (1867). The rule differs in two important respects, however: (1) It uses pragmatic terms rather than the technical “cause of action” to state the test for permitting relation back. (2) It applies only to amendments that would be time-barred: other amendments are permitted even if they do state a new claim. See 1A Barron & Holtzoff § 448. This approach in effect uses technicality only when necessary to protect the defendant from real prejudice. The last sentence of the first paragraph of Rule 15(c), in emphasizing a new defendant’s notice and knowledge of the original proceeding within the period of the statute of limitations, is consistent with prior Vermont practice in cases of misnomer. See Russell v. Barre Plywood Co., 116 Vt. 40, 68 A.2d 691 (1949); Hosford v. New York Central & Hudson River R. Co., 47 Vt. 533 (1875). Rule 15(d) is nearly identical to 12 V.S.A. § 1035 (now superseded). The rule, however, includes a provision, added to Federal Rule 15(d) after enactment of the Vermont statute, that permission to file a supplemental pleading may be granted even though the original pleading is defective. This change, intended only to state the result reached under the original federal rule by the better-considered cases, should work no change in Vermont practice.

Plain-English Summary

Rule 15(a) starts from a permissive premise. A party may amend a pleading once without asking the court, so long as no responsive pleading has been served yet or, if none is allowed, within 21 days after the pleading was served. After that window closes, amendment requires either the court's leave or the other side's written consent, and the rule tells courts to give that leave freely when justice calls for it. Whoever receives an amended pleading gets whichever period is longer: the time remaining to answer the original pleading, or 14 days from service of the amendment.

Section (b) covers what happens when the trial drifts past what the pleadings cover. If both sides try an issue nobody pled, either by saying so or by going along with the evidence without objection, the rule treats that issue as if it had been raised from the start. Either party may move to amend the pleadings to match what was tried, even after judgment, and failing to make that motion does not undo the result. When one side objects that evidence strays outside the pleadings, the court can allow amendment anyway, and should do so freely when it would help resolve the case on the merits without prejudicing the objecting party -- who can ask for a continuance to meet the new evidence if needed.

Section (c) governs relation back: whether a late amendment counts, for statute-of-limitations purposes, as though filed on the original date. An amendment relates back when the law governing the limitations period itself allows it, when it grows out of the same conduct, transaction, or occurrence already described in the original pleading, or when it corrects a party's name or identity. That last path also requires that the new party learned of the suit within the time allowed for serving a summons and complaint, will not be prejudiced in mounting a defense, and knew or should have known the suit would have named them but for a mistake about identity -- delivery to the Attorney General satisfies this notice requirement where the State of Vermont or one of its agencies is the party being brought in. Section (d) lets a party add a supplemental pleading covering events that happened after the original filing, even if that original pleading was itself defective, and the court can require a response to it on whatever schedule it sets.

Frequently Asked Questions

Do I need the court's permission to amend a pleading in Vermont?

Not right away. Rule 15(a) lets a party amend once as a matter of course before a responsive pleading is served, or within 21 days after service if no response is allowed. After that, amendment requires leave of court or the other party's written consent, though the rule directs courts to give leave freely when justice requires it.

How long do I have to respond to an amended pleading?

Whichever period is longer: the time remaining to respond to the original pleading, or 14 days after service of the amended pleading, unless the court orders otherwise.

What happens if an issue not in the pleadings gets tried anyway?

Under Rule 15(b), an issue tried by the express or implied consent of the parties is treated as if it had been raised in the pleadings all along. Either side may move to amend the pleadings to match the evidence, even after judgment, and the failure to do so does not affect the result reached on that issue.

What does it mean for an amendment to "relate back" to the original pleading?

Relation back treats a later amendment as though filed on the date of the original pleading, which matters once a statute of limitations has run in between. Under Rule 15(c), an amendment relates back when the applicable limitations law allows it or when it arises from the same conduct, transaction, or occurrence already set out in the original pleading.

Can I add or correct a defendant's name after the limitations period has expired?

Sometimes. Beyond arising from the same conduct or occurrence, the new party must have received notice of the action within the period allowed for serving the summons and complaint, must not be prejudiced in preparing a defense, and must have known or should have known that the suit would have named them but for a mistake about their identity.
