When must a Chancery motion to alter or amend judgment be filed?

Entry of judgment to be altered or amended

Identify the actual entered judgment. A later notification of entry does not supply this rule’s stated trigger.

Responsible actor. The party moving to alter or amend the entered judgment. Use the current Rule 59(b) judgment-entry branch. Do not substitute service, receipt or the date the judgment was announced.

1. Use the current Rule 59(b) judgment-entry branch. Do not substitute service, receipt or the date the judgment was announced.
2. Exclude the trigger day and count 10 days that are not Saturdays, Sundays or legal holidays under Rule 6(a)(1). These are short-period eligible days, not consecutive calendar days.
3. Check the actual holidays, additional closures and applicable electronic or paper boundary.
4. File and serve the motion by the ordinary boundary and preserve its actual filing. Verify the substantive grounds and any effect on finality separately.

Rule 6(a)(1) excludes the event day. Periods below eleven days exclude intermediate Saturdays, Sundays and legal holidays; eleven days or more include them. A final weekend or legal holiday moves forward for an after-event period and backward for a before-event period. Rule 6(a)(3) separately addresses actual Register inaccessibility for filings. Rule 6(a)(5) includes section 501 holidays and days declared by the Governor. Good Friday and Thanksgiving Friday are Delaware holidays. Sunday July 4, 2027 is observed Monday July 5. Check county-specific Sussex Return Day and additional actual closures separately; the bundled calendar does not determine those filing conditions.

Rule 6(c) adds three calendar days after the ordinary Rule 6(a) period only for an act measured after service made exclusively by mail. It applies to party acts, not Court acts. Electronic service, an entry-based clock and a filing-based clock do not acquire that addition merely because a paper copy is mailed. These calculations show the disclosed nonexclusive-mail base component; they do not implement the mail-only addition or infer service effectiveness.

These reviewed calculators use the official edition current as of June 1, 2026. Events before that date and backward periods crossing before that date receive no computed or paid date. This is publication coverage, not a finding that an actual procedural act is late. Historical editions, emergency measures, court-modified dates and actual additional closures require separate review.

Fictitious example

Use the current Rule 59(b) judgment-entry branch. Do not substitute service, receipt or the date the judgment was announced. Ordinary current-edition facts, no changed order and no exclusively mailed incoming service.

Fictitious current-edition facts. This is the disclosed component with no altered order or additional actual closure. It does not establish effective service, completed filing, judicial action or procedural entitlement. Exclusively mailed incoming-service additions require separate review.

Express extension exception

Rule 6(b)(2) names Rule 59(b). Do not infer automatic enlargement under the general good-cause rule.

Other relief

The motion may rely on a Rule 60 ground. A separate Rule 60 motion has different timing and finality effects.

Mail-only service and actual court schedule

Rule 6(c) adds three calendar days after the ordinary Rule 6(a) period only for an act measured after service made exclusively by mail. It applies to party acts, not Court acts. Electronic service, an entry-based clock and a filing-based clock do not acquire that addition merely because a paper copy is mailed. These calculations show the disclosed nonexclusive-mail base component; they do not implement the mail-only addition or infer service effectiveness.

Current edition and historical scope

These reviewed calculators use the official edition current as of June 1, 2026. Events before that date and backward periods crossing before that date receive no computed or paid date. This is publication coverage, not a finding that an actual procedural act is late. Historical editions, emergency measures, court-modified dates and actual additional closures require separate review.

• Use the current Rule 59(b) judgment-entry branch. Do not substitute service, receipt or the date the judgment was announced.
• The base calculation does not obtain an extension, resolve a different branch or establish that the responsible actor completed the required act.

• Entry of judgment to be altered or amended
• Identify the actual entered judgment. A later notification of entry does not supply this rule’s stated trigger.
• Rule 6(b)(2) names Rule 59(b). Do not infer automatic enlargement under the general good-cause rule.
• The motion may rely on a Rule 60 ground. A separate Rule 60 motion has different timing and finality effects.
• File and serve the motion by the ordinary boundary and preserve its actual filing. Verify the substantive grounds and any effect on finality separately.
• For electronic service and filing, Rule 5(d) uses midnight for an original complaint, notice of appeal, or paper in a summary proceeding or an action ordered expedited. Other papers in other actions must be served or filed by 5:00 p.m. Use Delaware local court time and preserve actual completed transmission and docket treatment. Do not replace the ordinary boundary with a federal midnight rule. Rule 5(c)(2)(B) permits self-represented delivery to the Register with the required fee, deemed filed when delivered. Check actual office availability. Rule 5(e) permits the Court, on satisfactory proof, to deem an unsuccessful electronic attempt timely; relief is not automatic.
