A federal plaintiff can usually take a voluntary dismissal without prejudice and refile later. Rule 41(a) offers three ways to do it: a notice of dismissal filed before the defendant serves an answer or a summary-judgment motion, a stipulation signed by every party who has appeared, or a court order on terms the judge considers proper. Refiling is where the risk sits.
This guide covers voluntary dismissal in federal court. Most states have a rule modeled on Rule 41, with differences, so check your own state's version before relying on this.
The three paths under Rule 41(a)
Rule 41(a) sorts voluntary dismissals by how far the case has gone:
| Path | Rule | Who must agree | Cutoff |
|---|---|---|---|
| Notice of dismissal | 41(a)(1)(A)(i) | No one. No court order needed. | Ends once the opposing party serves an answer or a motion for summary judgment |
| Stipulation of dismissal | 41(a)(1)(A)(ii) | Every party who has appeared signs | None in the rule |
| Court order | 41(a)(2) | The judge, "on terms that the court considers proper" | Any time the first two are unavailable |
The notice is the cheapest path. The rule says the plaintiff "may dismiss an action without a court order by filing" it, and the dismissal takes effect on filing. In Waetzig v. Halliburton Energy Services, Inc., 604 U.S. 305 (2025), the Supreme Court described the mechanics: because the defendant had not yet answered or moved for summary judgment, the plaintiff's dismissal "was effective without any court action."
Rule 41(a)(1)(A) is also made "[s]ubject to Rules 23(e), 23.1(c), 23.2, and 66 and any applicable federal statute." Those rules cover certified class actions (or a class proposed for settlement), derivative suits, class suits by or against the members of an unincorporated association, and cases in which a receiver has been appointed, where court approval is required. If your case is one of those, the notice path may not be open at all.
What closes the notice window
The notice path closes when the opposing party serves "either an answer or a motion for summary judgment."
A motion to dismiss under Rule 12(b) is on neither list, so by the rule's text it does not cut off your right to dismiss by notice. The Fifth Circuit enforced that text in Pilot Freight Carriers, Inc. v. International Brotherhood of Teamsters, 506 F.2d 914 (5th Cir. 1975), where a plaintiff filed a Rule 41(a)(1) notice after the district court denied its request for a preliminary injunction and before any answer or summary-judgment motion. The court held the plaintiff "was entitled to dismiss its complaint under F.R.C.P. 41(a)(1)," and said that if a broader modification of the rule were desirable, "the request must be addressed to the Supreme Court and to Congress, not to this Court." The opinion also cites an earlier Fifth Circuit decision treating motions to dismiss for failure to state a claim or lack of subject-matter jurisdiction as not equivalent to a summary-judgment motion under the rule.
Two cautions. The rule counts service, so check the date the opposing party actually served the answer or motion. And a Rule 12 motion stuffed with exhibits, or one that asks in the alternative for summary judgment, can be argued to be a summary-judgment motion. If the timing is close, do not rely on the label: work out the dates (see calculating court deadlines) and file early.
Once an answer has been served, the notice path is gone. Our guide on how to answer a complaint covers what counts as one.
Stipulation and court order: when the notice is gone
A stipulation of dismissal under 41(a)(1)(A)(ii) needs the signatures of "all parties who have appeared." A defendant who was never served and has not appeared does not have to sign. The practical problem is that a defendant who thinks it is winning may refuse, or sign only for a price.
When no one will sign, you move under Rule 41(a)(2). The text says an action "may be dismissed at the plaintiff's request only by court order, on terms that the court considers proper." A defendant that has put real work into the case will argue it should not have to start over for free, and the "terms" language is where that argument lands.
The rule also protects defendants. If the defendant "has pleaded a counterclaim before being served with the plaintiff's motion to dismiss," the case "may be dismissed over the defendant's objection only if the counterclaim can remain pending for independent adjudication." Dropping your claim does not make the defendant's claims against you go away.
Is a voluntary dismissal without prejudice by default?
Rule 41(a)(1)(B) sets the default for notices and stipulations: "Unless the notice or stipulation states otherwise, the dismissal is without prejudice." Rule 41(a)(2) works the same way: "Unless the order states otherwise, a dismissal under this paragraph (2) is without prejudice."
Read the order or stipulation closely. A stipulation drafted by the other side may say "with prejudice," and a court granting a 41(a)(2) motion can say the same.
Say what you mean in your own notice. A one-line notice of voluntary dismissal that states it is "without prejudice" removes any argument about the default.
Without prejudice means the dismissal is not an adjudication on the merits, so you keep the right to sue on the same claims again. The Supreme Court said so in Waetzig: a first-time dismissal is "presumptively 'without prejudice,'" which "means that [the plaintiff] had preserved his right to refile the same claims in the future."
Can you refile after a voluntary dismissal?
Preserving the right to refile does not make refiling safe. Three things can bite.
1. The two-dismissal rule
The second sentence of Rule 41(a)(1)(B) is the trap: "if the plaintiff previously dismissed any federal- or state-court action based on or including the same claim, a notice of dismissal operates as an adjudication on the merits."
Three details matter:
- It applies to a second notice dismissal. A stipulation or court-ordered dismissal does not trigger the merits effect by its terms.
- The earlier dismissal can be in any federal or state court. A voluntary dismissal of a state case last year can count.
- It reaches the same claim, even if it is in a different case with different parties around it.
2. Rule 41(d) costs
Rule 41(d) puts a price on a restart. If a plaintiff "who previously dismissed an action in any court files an action based on or including the same claim against the same defendant," the court "may order the plaintiff to pay all or part of the costs of that previous action" and "may stay the proceedings until the plaintiff has complied." The word is "may," so the award is discretionary, but a defendant that paid to litigate the first suit has every reason to ask. Budget for it.
3. The statute of limitations
A dismissal without prejudice does not end the claim, but it does not stop the clock by itself either. Whether the time the first case was pending counts against you depends on the law that supplies the limitations period. Some states have savings statutes that give a plaintiff a fixed window to refile after a voluntary dismissal. Others do not. Do not assume either one. Find the statute for your claim and your jurisdiction, and put the date on the calendar before you file the notice. Our post on the Utah statute of limitations shows what that lookup involves for one state.
For state-law claims that are in federal court only because of supplemental jurisdiction, 28 U.S.C. § 1367(d) provides that the limitations period for a claim asserted under § 1367(a) "shall be tolled while the claim is pending and for a period of 30 days after it is dismissed unless State law provides for a longer tolling period." It also reaches other claims in the same action "voluntarily dismissed at the same time as or after the dismissal of the claim." That helps, but it is not a promise. It is tied to a claim that rested on supplemental jurisdiction, and whether your claim fits is a research question, not an assumption.
The sound rule: the date the limitations period expires, not the date of dismissal, decides whether you can refile. Work backward from it.
Can a voluntary dismissal be reopened?
A plaintiff who dismisses by notice sometimes wants to undo it. In Waetzig, a unanimous Court held that "a Rule 41(a) voluntary dismissal without prejudice qualifies as a 'final . . . proceeding' under Rule 60(b)." The Court added that "[w]hen the requirements of Rule 60(b) are satisfied, a district court may relieve a party from such a dismissal and reopen the case."
That is narrower than it sounds. The plaintiff in Waetzig got a chance to ask. The Court said it expressed "no view on whether that relief was proper" in his case. Rule 60(b) has its own grounds and deadlines, which we covered in our guide to a motion for reconsideration. Treat reopening as a rescue for a mistake, not a plan.
Dropping one claim or one defendant
Rule 41(a) speaks of dismissing "an action," and the circuits do not read that the same way.
- Dropping all claims against one defendant is allowed under Rule 41(a) by most courts, as the Ninth Circuit noted in the case below. The Seventh Circuit reads the rule more narrowly.
- Dropping one claim while the rest of the case continues is where they disagree. In Hells Canyon Preservation Council v. U.S. Forest Service, 403 F.3d 683 (9th Cir. 2005), the Ninth Circuit read Rule 41(a) to reach dismissal of all claims against a defendant, not individual claims against a remaining defendant, and treated the plaintiff's withdrawal as an amendment under Rule 15(a). The Seventh Circuit goes further. In Taylor v. Brown, No. 12-1710 (7th Cir. June 2, 2015), it repeated its earlier statement that Rule 41(a) "does not speak of dismissing one claim in a suit; it speaks of dismissing 'an action'—which is to say, the whole case," held that Rule 41(a) was the wrong vehicle for dropping a prisoner's claim against one officer while his claim against other defendants went forward, and pointed to Rule 15(a) instead. That opinion also acknowledges that "some courts have held otherwise" and that other circuits "appear divided."
To drop part of a case, check which rule your circuit applies. When in doubt, move to amend under Rule 15(a) and say so in the caption.
The contrast: Rule 41(b) involuntary dismissal
Rule 41(b) covers the dismissal a plaintiff does not choose: "If the plaintiff fails to prosecute or to comply with these rules or a court order, a defendant may move to dismiss the action or any claim against it."
The default runs the other way. "Unless the dismissal order states otherwise, a dismissal under this subdivision (b) and any dismissal not under this rule—except one for lack of jurisdiction, improper venue, or failure to join a party under Rule 19—operates as an adjudication on the merits."
A case the plaintiff stops prosecuting can end with prejudice. If you want out because you cannot keep up with the case, file the notice or motion while you still can rather than wait to be dismissed. If the reason is a pleading you now doubt, read our guide to Rule 11 sanctions before you decide how to exit.
Frequently asked questions
Can I refile after a voluntary dismissal without prejudice?
Usually yes, if the limitations period has not run. A dismissal without prejudice is not an adjudication on the merits, so claim preclusion does not bar a new suit. But a second notice dismissal of the same claim is a merits adjudication, the court may order you to pay the first case's costs, and the statute of limitations keeps running unless a tolling rule applies.
What is the two-dismissal rule?
Under Rule 41(a)(1)(B), if a plaintiff already dismissed any federal or state action based on or including the same claim, a second notice of dismissal operates as an adjudication on the merits. The rule applies to notice dismissals, and the first dismissal can come from a state-court case.
Can the defendant stop me from voluntarily dismissing my case?
Not before the cutoff. Until the defendant serves an answer or a motion for summary judgment, you may file a notice of dismissal without anyone's consent or a court order. After that, you need a stipulation signed by every party who has appeared, or a court order under Rule 41(a)(2) on terms the court considers proper.
Does a motion to dismiss stop me from filing a notice of voluntary dismissal?
By the text of Rule 41(a)(1)(A)(i), no. The cutoff is service of an answer or a motion for summary judgment, and a Rule 12 motion to dismiss is neither. Check your circuit and local rules, because a defendant may attach evidence or style a motion as one for summary judgment, which can change the analysis.
Can a voluntarily dismissed case be reopened?
Sometimes. In Waetzig v. Halliburton Energy Services (2025), the Supreme Court unanimously held that a case voluntarily dismissed without prejudice under Rule 41(a) counts as a final proceeding under Rule 60(b). A district court may reopen it, but only when the movant meets Rule 60(b)'s requirements and within its time limits.
Check the cites before you file
A notice of dismissal needs no authority. A Rule 41(a)(2) motion does, and so does an answer to a Rule 41(d) costs request or an argument that your limitations period was tolled. In CaseRead, you can ask how your circuit treats the terms of a Rule 41(a)(2) dismissal with the research scoped to your matter, and put the limitations date on the matter's deadline calendar before you file. If any authority in your draft came from a general-purpose AI tool, run the draft through the Hallucination Shield first. It is free, needs no signup, and checks up to 50 citations per run, flagging any it cannot verify.
