United States · Federal district-court post-judgment motion

When must I file a motion for amended or additional findings?

Rule 52(b) permits the court, on a party’s motion filed no later than twenty-eight days after judgment entry, to amend findings or make additional findings and amend judgment accordingly. The motion may accompany a Rule 59 new-trial motion. Rule 6(b)(2) prohibits enlarging its time.

Which event starts this motion period?

Use the twenty-eight-day filing period for an actual Rule 52(b) motion concerning the court’s findings.

Confirm the findings and actual Rule 52(b) relief. The rule permits an accompanying Rule 59 new-trial motion. Rule 52(a)(5) separately allows a party to question evidentiary sufficiency whether or not it requested findings, objected or moved to amend them.

Establish judgment entry under Rule 58(c) through the actual civil docket and any required separate document. Announcement, verdict, signature and notice receipt do not automatically establish entry.

FRCP 58(c)

How are the twenty-eight calendar days counted?

  1. Establish judgment entry and the actual motion.
  2. Exclude the entry day.
  3. Count twenty-eight calendar days.
  4. Apply qualifying final-day holidays or inaccessibility and verify filing.

Exclude the independently established judgment-entry date. Count every following calendar day, including intermediate Saturdays, Sundays and legal holidays. These are district-court Civil Rules motions, even though the catalogue groups them beside appeal-related motions.

Rule 6(a)(1) carries a final Saturday, Sunday or legal holiday to the next qualifying day. Rule 6(a)(6) includes federal and President or Congress declared holidays. For this forward period, check additional holidays declared by the state where the district court is located. Qualifying clerk inaccessibility under Rule 6(a)(3) is a separate condition.

FRCP 6(a)(1)

What does an independently checked example show?

Fictitious example

Fictitious judgment entry is independently established as July 6. No additional declared holiday, clerk inaccessibility or disputed motion classification is assumed.

Which conditions need separate review?

A motion for amended or additional findings
Confirm the findings and actual Rule 52(b) relief. The rule permits an accompanying Rule 59 new-trial motion. Rule 52(a)(5) separately allows a party to question evidentiary sufficiency whether or not it requested findings, objected or moved to amend them.
Established entry
Rule 58(c) uses civil-docket entry when no separate document is required. If one is required, establish docket entry and the earlier of the separate document or 150 days from docket entry. This page does not derive that date.
No routine enlargement
Rule 6(b)(2) prohibits enlarging time under FRCP 52(b). An agreement or requested extension does not establish timely filing.
Separate appeal consequences
FRAP 4(a)(4) addresses listed motions filed within their allowed time and the order disposing of the last remaining motion. This page does not determine whether a filing qualifies or calculate appeal expiry.
Separate service and local instructions
Read the district’s filing requirements and applicable service provisions. A notice, draft, service attempt or merits argument does not establish completed timely filing.
FRCP 52(b)
  • This page does not determine the motion’s merits or establish proper motion classification.
  • It does not establish completed filing, an automatic extension, a stay or a notice-of-appeal deadline.

What should I verify before filing?

Common questions

A motion for amended or additional findings

Can this motion accompany a new-trial motion?

Yes. Rule 52(b) expressly permits it to accompany a Rule 59 motion. Each actual motion still requires its own applicable conditions and timely filing.

FRCP 52(b)

Must I move to amend findings before questioning evidentiary sufficiency?

Rule 52(a)(5) permits a later sufficiency challenge whether or not the party requested findings, objected or moved to amend them. This statement does not resolve a separate appellate procedure or deadline.

FRCP 52(a)(5)

Is this an appellate-court filing?

No. The motion seeks relief in the district court under the Civil Rules. Its possible effect on appeal timing is a separate Rule 4(a)(4) question.

FRAP 4(a)(4)

Can an ordinary good-cause extension enlarge this period?

No. Rule 6(b)(2) prohibits extending time to act under FRCP 52(b). Its prohibition is separate from Rule 6(a)’s computation and qualifying clerk-inaccessibility provisions.

FRCP 6(a)(1)–(6) and (b)(2)

Does mailed notice of judgment add three days?

No. The operative event is judgment entry, or the specifically applicable Rule 50(b) jury discharge. Rule 6(d) concerns specified periods after service. It does not replace either event.

FRCP 6(d)
