FRCP 60(b)(1): Relief From a Judgment, Explained

By Steve Levine · Updated July 19, 2026 · 7 min read

Quick Answer

Federal Rule of Civil Procedure 60(b)(1) lets a federal court, on motion and just terms, relieve a party from a final judgment, order, or proceeding for mistake, inadvertence, surprise, or excusable neglect. It is how a party asks a court to undo something — like a default judgment or a dismissal — that resulted from an error or an understandable slip, instead of appealing. The motion must be filed within a reasonable time and, for this ground, no more than one year after the judgment or order was entered. Whether "excusable neglect" is present is judged under the flexible balancing test from Pioneer Investment Services Co. v. Brunswick Associates (1993).

What the Rule Says

Rule 60(b) is the federal rule that lets a court reopen a matter after it is over. It opens: "On motion and just terms, the court may relieve a party or its legal representative from a final judgment, order, or proceeding" for one of six listed reasons. The very first reason — subsection (1) — is mistake, inadvertence, surprise, or excusable neglect. In everyday terms, it is the mechanism a party uses to ask the trial court to vacate (undo) something that has already been decided, rather than taking the issue up to an appeals court.

Two things are worth fixing in mind up front. First, 60(b)(1) reaches a "judgment, order, or proceeding" — it is not limited to a full final judgment, though relief from truly final judgments is where it does its heaviest lifting. Second, relief is discretionary: the words "may relieve" and "just terms" mean the court weighs the request and can grant it, deny it, or condition it, rather than being required to act.

The Four Grounds in 60(b)(1)

Subsection (1) packs four related ideas into one clause:

• Mistake — an error, which courts have applied both to a party's own error and, in some circuits, to certain legal errors by the court.
• Inadvertence — an unintentional oversight or slip.
• Surprise — being caught off guard by something a party could not reasonably have anticipated or guarded against.
• Excusable neglect — a failure to act that, while negligent, is understandable and forgivable under the circumstances. This is the ground courts analyze most often, and it carries the most developed body of case law.

These overlap, and a motion often invokes more than one. What unites them is that the party is not claiming a strategic right to a do-over; it is explaining an error, oversight, or genuine surprise and asking the court to correct the consequences.

The Deadline: "Reasonable Time" and One Year

Timing is governed by Rule 60(c). Every Rule 60(b) motion must be made "within a reasonable time." On top of that, motions on grounds (1), (2), and (3) — which includes the 60(b)(1) grounds — carry a hard outer limit: no more than a year after the entry of the judgment or order or the date of the proceeding.

A common misconception is that the one-year period is a grace window you can freely use. It is not. The one year is a ceiling, and the "reasonable time" requirement operates independently — a court can deny a 60(b)(1) motion filed at, say, month ten if the movant sat on the problem after discovering it. Filing an appeal, importantly, does not stop the clock, and a pending Rule 60(b) motion does not by itself extend the deadline to appeal the underlying judgment. The safe practice is to move promptly once the mistake or neglect comes to light.

How Courts Judge "Excusable Neglect"

The controlling framework comes from the U.S. Supreme Court's decision in Pioneer Investment Services Co. v. Brunswick Associates Ltd. Partnership, 507 U.S. 380 (1993). Although Pioneer arose under a bankruptcy rule, its definition of "excusable neglect" has been widely applied across the Federal Rules, including Rule 60(b)(1) and Rule 6(b). The Court held that "neglect" can include ordinary carelessness — not just events beyond a party's control — and that whether it is "excusable" is an equitable determination weighing all the circumstances. Courts look at four factors:

• Prejudice — the danger of harm to the opposing party if relief is granted.
• Length and impact of the delay — how long the party waited and what effect that has on the case and the court.
• Reason for the delay — including whether it was within the movant's reasonable control.
• Good faith — whether the movant acted in good faith.

No single factor controls, and results are fact-specific. A missed deadline caused by a genuine calendaring error, a clerical slip, or a breakdown in notice is more likely to be excused than one caused by a deliberate tactical choice, a party ignoring clear instructions, or unexplained inattention. Because the test is discretionary, two courts can reach different outcomes on similar facts.

Why It Matters in Class Actions

For most class members, Rule 60(b)(1) sits in the background — but it can surface in a few real situations. It is the rule behind a motion to set aside a default judgment or a dismissal that resulted from an error, and it occasionally appears when a party seeks to reopen an order entered by mistake. Because it shares the excusable-neglect standard with Rule 6(b)(1)(B) (the rule for extending a deadline that has already passed), the two are often discussed together; the practical difference is timing — 6(b)(1)(B) is used before a final judgment, 60(b)(1) after one exists.

The situation class members most often ask about is a missed deadline — a claim-filing deadline, an opt-out deadline, or an objection deadline. Those deadlines are set by the settlement agreement and the court's orders, and the normal first step for a late claim form is to contact the settlement administrator — not to file a Rule 60(b) motion. Whether Rule 60(b) could ever reach a missed class deadline is a fact-specific legal question that depends on the posture of the case. If you are facing a blown deadline in a case that matters to you, the right move is to talk to a lawyer or to class counsel quickly, because the "reasonable time" requirement rewards acting fast.

Frequently Asked Questions

What is Rule 60(b)(1)?

Rule 60(b)(1) of the Federal Rules of Civil Procedure lets a federal court relieve a party from a final judgment, order, or proceeding for mistake, inadvertence, surprise, or excusable neglect. It is the tool a party uses to ask a court to undo (vacate) something like a default judgment or a dismissal that resulted from an error or an understandable slip, rather than appealing it.

What is the deadline to file a Rule 60(b)(1) motion?

A motion under Rule 60(b)(1) must be made within a reasonable time, and in no event more than one year after the judgment or order was entered. That one-year limit is an outer boundary, not a safe harbor — a court can still deny a motion filed inside the year if it was not made within a reasonable time under the circumstances.

What does "excusable neglect" mean?

Excusable neglect is judged under the flexible standard the U.S. Supreme Court set out in Pioneer Investment Services Co. v. Brunswick Associates (1993). Courts weigh the danger of prejudice to the other side, the length of the delay and its effect on the case, the reason for the delay and whether it was in the movant's control, and whether the movant acted in good faith. A simple mistake or oversight can qualify, but a deliberate or strategic choice generally does not.

How is Rule 60(b)(1) different from Rule 6(b)(1)(B)?

Both use the excusable-neglect standard, but they do different jobs. Rule 6(b)(1)(B) is used before there is a judgment, to ask the court to extend a deadline that has already passed. Rule 60(b)(1) is used after a final judgment or order exists, to ask the court to reopen or undo it. Which rule applies depends on whether the case has reached a final judgment yet.

Can a class member use Rule 60(b)(1) to file a late claim?

Not usually as a first step. Claim deadlines in a class action settlement are set by the settlement agreement and the court's orders, and the normal path for a late claim is to ask the settlement administrator or, if needed, the court overseeing the settlement. Rule 60(b) is aimed at judgments and orders, and whether it could reach a missed claim or opt-out deadline is a fact-specific legal question. This page is general information, not legal advice — anyone in that situation should consult a lawyer or class counsel.
