How is the Chancery response deadline to an amended pleading selected?

Service of the amended pleading and the unexpired original response deadline

Calculate both applicable branches with their own service and counting qualifications. Select the later unless the Court orders otherwise.

Responsible actor. The party required to respond to the amended pleading. Establish the original response deadline, amended-pleading service and any different court order.

1. Service of the amended pleading and the unexpired original response deadline
2. Calculate both applicable branches with their own service and counting qualifications. Select the later unless the Court orders otherwise.
3. Identify the actual competing event, court order or statutory condition described here before applying Rule 6. No single date is computed.
4. Preserve both response clocks and serve and file the required response by the controlling later boundary.

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 one amended pleading leaves a later original response deadline, while another arrives after that original period has ended. The same ten-day component cannot select both controlling dates.

The preset cannot compare the unexpired original response time with the ten-day amended-pleading branch. No computed or paid date is published.

Later comparison

The ten-day branch cannot displace a later original response deadline.

Mail-only service

Rule 6(c) can affect a period measured after service made exclusively by mail. Review each clock separately.

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.
