The California motion to bifurcate deadline is set by Code of Civil Procedure Section 598: the court’s bifurcation order must be entered no later than 30 days before the scheduled trial date, or by the close of the pretrial conference if one is held. Because the statute governs when the order must issue, not when the motion must be filed, the papers themselves have to be filed, served, and heard several weeks earlier. Plan backward from trial.
What CCP 598 Actually Requires
CCP 598 authorizes the trial court to order that “the trial of any issue or any part thereof shall precede the trial of any other issue” when doing so promotes witness convenience, the ends of justice, or the economy and efficiency of the litigation. The statute sets two possible deadlines for the order:
- If the court holds a pretrial conference, the bifurcation order must be entered no later than the close of that conference.
- In all other cases, the order must be entered no later than 30 days before the trial date.1California Legislative Information. California Code CCP 598 – Issues, The Mode of Trial and Postponements
Read the statute carefully. The 30 days runs to the order, not the motion. A judge needs time to receive the papers, read the opposition and reply, hold a hearing, and rule. Filing a motion 31 days before trial and expecting a same-day ruling is not a realistic plan.
Working the Timeline Backward From Trial
The controlling notice rule is CCP 1005, which requires all moving papers to be served and filed at least 16 court days before the hearing. Court days exclude weekends and court holidays, so 16 court days translates to roughly three and a half calendar weeks.2California Legislative Information.

Depending on the method of service, extra time is added to that 16-court-day minimum:
- Mail within California: add 5 calendar days.
- Mail outside California but within the United States: add 10 calendar days.
- Express mail or overnight delivery: add 2 calendar days.2California Legislative Information. California Code of Civil Procedure 1005 – Written Notice for Motions
- Electronic service: add 2 court days.3Judicial Branch of California. LEG15-03 Timing of Electronic Service – Amendment to Code of Civil Procedure 1005
Opposition papers are due 9 court days before the hearing, and any reply is due 5 court days before, under CCP 1005(b). Those windows have to fit inside your calendar too.
Put it together for a typical case with no pretrial conference and service by mail within California. The order must exist 30 days before trial. The hearing should sit a few days before that cutoff so the judge has room to rule and sign. The moving papers must be served at least 16 court days plus 5 calendar days before the hearing. That pushes the realistic filing window to roughly seven to eight weeks before the trial date. File later than that and you are gambling on the court’s calendar having an opening.
Check Local Rules Before You Calendar
County superior courts can impose stricter deadlines. Some require motions in limine and bifurcation requests to be filed with trial documents by a set number of days before trial. Confirm the local rules for the county where the case is pending before you rely on the statewide numbers alone.
If You Miss the Deadline
The court still retains the power to order bifurcation on its own initiative “at any time.”1California Legislative Information. California Code CCP 598 – Issues, The Mode of Trial and Postponements A judge who sees mid-case that splitting issues would save days of testimony can order the split then. But that language protects the court’s discretion; it is not an invitation for parties to skip the deadline and hope for a rescue.
There is a second route. CCP 1048(b) allows separate trials of entire causes of action, cross-complaints, or groups of issues “in furtherance of convenience or to avoid prejudice.” Section 1048(b) does not carry the 30-day deadline that Section 598 imposes, and courts sometimes rely on it, alone or alongside Section 598, when the separation involves distinct claims rather than a straightforward liability-damages split. If you are past the Section 598 window, a Section 1048(b) request may still be viable.
Special Defenses Are on a Separate Track
CCP 598 expressly carves out special defenses that can be tried first under CCP 597 and 597.5. These are threshold defenses that end the case if they succeed: statute of limitations, claims that a prior judgment bars the action, and arguments that another case on the same dispute is already pending.4California Legislative Information. California Code of Civil Procedure CCP 597 – Special Defenses They have their own bifurcation procedure and do not run through Section 598’s 30-day clock.
Federal Court Follows a Different Rule
Cases in California’s federal district courts are governed by Federal Rule of Civil Procedure 42(b), not CCP 598. Rule 42(b) allows a court to order separate trials “[f]or convenience, to avoid prejudice, or to expedite and economize” and imposes no specific calendar deadline; the court can order bifurcation at any time.5Legal Information Institute (Cornell Law School). Rule 42. Consolidation; Separate Trials The federal factors track California’s but are not identical, and any federal bifurcation order must preserve the parties’ Seventh Amendment jury-trial right, so the court has to divide issues carefully to avoid having a second jury re-decide facts the first jury already resolved.
The Practical Takeaway on Timing
Two dates matter, and only one of them is in the statute. The statutory date is 30 days before trial (or the close of the pretrial conference), and that is the date the court’s order must exist by. The date you actually control is the filing date, which needs to sit far enough ahead of the statutory deadline that the notice period under CCP 1005, any service add-ons, opposition and reply windows, and the hearing itself all fit before the cutoff. Seven to eight weeks before trial is a workable target for standard service; earlier is safer, and local rules may require it.
