When may a claimant first seek summary judgment in Chancery?

Commencement of the action, or service of the adverse party’s summary-judgment motion

The alternatives can permit different earliest acts. A defending party has its own any-time branch.

Responsible actor. The party seeking recovery on a claim. Identify commencement, an adverse summary-judgment motion and any good-cause requirement imposed by the Court.

1. Commencement of the action, or service of the adverse party’s summary-judgment motion
2. The alternatives can permit different earliest acts. A defending party has its own any-time branch.
3. Identify the actual competing event, court order or statutory condition described here before applying Rule 6. No single date is computed.
4. Establish permission under the applicable branch and comply with the Court’s motion schedule and factual-support requirements.

The source guide explains the actual missing comparisons or procedural conditions. No computed or paid date is supplied.

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.

Assume an adverse summary-judgment motion is served before the commencement waiting period expires. Compare that actual event with the different no-adverse-motion branch.

The preset cannot select earliest permission between a waiting-period expiration, an adverse motion and required court leave. It is not a filing cutoff.

Alternative triggering act

Service of the adverse party’s summary-judgment motion supplies another permission route.

Good-cause leave

The Court may require a party wishing to move to show good cause.

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.

• 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.
