When must a party demand a jury trial under Rule 38?

For an issue triable of right by jury, Rule 38(b) ordinarily requires serving a written demand no later than fourteen days after the last pleading directed to that issue is served, and filing the demand under Rule 5(d). The relevant issue, pleading and incoming service must be established.

Responsible actor. The party demanding trial by jury on an issue triable of right by jury.

Identify the particular issue and whether it is triable of right by jury. The rules do not create a jury right for every claim.

Read the pleadings directed to that issue and establish which is the last. Do not choose the first document simply because it arrived first.

Rule 7(a) distinguishes pleadings from motions. A Rule 12 motion is not a pleading merely because it addresses the case.

Preserve effective service of the actual last issue pleading and identify any separate Rule 38(c) demand on additional issues.

This source guide requires an established jury-triable issue, last relevant pleading and effective service method. It publishes no automatic date or paid calculation. A date-only input cannot establish those facts or completed demand service and filing.

1. Identify the selected procedural act and responsible party.
2. Establish every required qualifying document, operative event and actual service method.
3. Apply only the supported period, sequential service addition and any required earlier-or-later comparison.
4. Check actual orders, stipulations, local conditions and completion of the required service or filing.

FRCP 6(a) excludes the operative event day, counts intermediate calendar days and continues a final Saturday, Sunday or legal holiday to the next qualifying day. When Rule 6(d) applies, its three days follow the period’s ordinary Rule 6(a) expiration. Electronic service receives no Rule 6(d) addition. Establish the authorized service method rather than adding three days to every service-based period.

FRCP 6(a)(6) includes the listed federal holidays, declared presidential or congressional holidays and, for forward periods, holidays declared by the state where the district court sits. Actual clerk inaccessibility has separate Rule 6(a)(3) treatment for filing. Check the named court, actual orders and additional state holidays. A national calendar alone cannot establish them.

Assume a jury-triable issue and the established last pleading directed to that issue electronically served October 6, 2026. Fourteen days after the established service event is October 20. Rule 38(b) requires serving the written demand and filing under Rule 5(d). The example establishes neither a jury right nor completed service and filing. This guide publishes no computed date.

Assume that established last pleading served by qualifying mail October 6, 2026. The ordinary fourteen-day expiration is October 20. Rule 6(d) then adds three days, giving October 23 under the stated facts. Preserve the actual incoming service method. The fourteen-day number alone does not establish this branch.

Assume a complaint served October 6 and a later answer directed to the same jury issue electronically served October 20. Rule 38(b) uses the last pleading directed to the issue. With that assumption, the October 20 answer supplies the event and the fourteen-day illustration reaches November 3. Do not select the first pleading mechanically. A motion is not a pleading under Rule 7(a).

Assume the established last issue pleading effectively served electronically July 4, 2026. Fourteen days reaches Saturday, July 18. Rule 6(a) continues the ordinary endpoint to Monday, July 20 under the stated holiday facts. Both serving and filing the demand remain necessary. The source guide does not certify either act.

Issue-specific last pleading

Rule 38(b) identifies the last pleading directed to the issue. Establish that relationship from the actual pleadings, rather than using any docket document.

Pleading differs from motion

Rule 7(a) enumerates pleadings. Motions under Rule 7(b) do not automatically become the last pleading for Rule 38(b).

Additional issues

Where a demand specifies only some issues, Rule 38(c) supplies a separate demand route for other jury-triable factual issues within fourteen days after demand service or a shorter court-ordered time.

Waiver and possible later relief

Rule 38(d) addresses waiver absent proper service and filing. Rule 39(b) provides a discretionary court-ordered jury route; it is not an automatic extension.

• This source guide requires an established jury-triable issue, last relevant pleading and effective service method. It publishes no automatic date or paid calculation. A date-only input cannot establish those facts or completed demand service and filing.
• An ordinary Rule 38(b) demand, a Rule 38(c) additional-issue demand and a post-removal jury demand have different operative events. A discretionary Rule 39(b) request is a separate procedure.

• Identify the particular jury-triable issue.
• Preserve all pleadings directed to that issue.
• Establish the last qualifying pleading and its effective service method and date.
• Check any earlier limited demand and Rule 38(c) additional-issue branch.
• Read actual directions and any requested or granted Rule 39(b) relief separately.
• Serve the written demand and complete filing under Rule 5(d).
• Rule 38(b) requires written demand service and filing under Rule 5(d). Do not equate drafting, docket entry of another pleading or an email without established service authority with completion. Check actual filing acceptance, authorized service and any different court time.
