When must a responsive pleading be served after a Rule 12 motion is denied?

Unless the court sets a different time, Rule 12(a)(4)(A) requires serving the responsive pleading within fourteen days after notice that the court denied the served Rule 12 motion or postponed its disposition until trial. An unrelated deferral, filing a motion alone or assumed order entry does not establish this event. This calculator covers the independently established ordinary notice branch.

Which event starts this procedure?

Establish that a Rule 12 motion was served and that the court denied it or postponed its disposition until trial.

Preserve actual qualifying notice of that court action. An assumed order-entry date or the original complaint-service date does not establish the notice event.

Confirm that the court sets no different time and no actual enlargement or separate controlling statute changes the period.

FRCP 12(a)(4)(A)

How is the ordinary period counted?

  1. Identify the actual actor, pleading and required act.
  2. Establish the specified event and applicable order.
  3. Exclude the verified event day and count the scoped calendar-day period.
  4. Check final-day conditions and preserve service and filing evidence separately.

Exclude the independently established event and count each following calendar day under Rule 6(a)(1). The scoped event is not a Rule 5 service event automatically attracting Rule 6(d).

Rule 6(a)(1) excludes the event day and counts intermediate calendar days. A final Saturday, Sunday or legal holiday carries the period forward to the next qualifying day. Rule 6(a)(6) includes federal and President or Congress declared holidays, plus state-declared holidays for forward periods in the district. Qualifying clerk inaccessibility is a separate filing condition.

FRCP 6(a)(1)

What does an independently checked example show?

Fictitious example

A fictitious served Rule 12 motion is denied, or its disposition is postponed until trial. Qualifying notice of that action is independently established as July 6. The court sets no different time.

Which conditions change the assessment?

Serving the Rule 12 motion
The opening words of Rule 12(a)(4) concern serving a motion under that rule. A filing label alone does not establish that condition.
Qualifying court action
Subsection (A) specifies denial or postponing disposition until trial. Do not substitute an unrelated scheduling deferral or the grant of a more-definite-statement motion.
Different court time
The opening words expressly yield when the court sets another time. Read the actual order rather than assuming fourteen days always controls.
Actual court enlargement
Rule 6(b)(1) permits actual court enlargement for good cause. Before expiry, the court may act with or without motion or notice, or a request may be made. After expiry, a motion requires failure to act because of excusable neglect. A request or agreement is not a granted extension.
FRCP 12(a)(4)(A)
  • This page does not establish effective service, merits, compliance or an actual court grant.
  • Service and filing are different acts. Verify both when required.

Common questions

This procedure and its conditions

Does order entry automatically replace notice?

No. Rule 12(a)(4)(A) specifies notice of the court’s qualifying action. Establish actual notice rather than assuming another event supplies it.

FRCP 12(a)(4)(A)

Does every deferral start this fourteen-day period?

No. The text specifies denial or postponing disposition until trial. Establish that actual action and the court’s stated time.

FRCP 12(a)(4)

Does mailed notice automatically add three days?

No. Rule 6(d) applies to specified periods after being served under its listed Rule 5 methods. It does not automatically add three days to every period described as after notice.
