Motion to Bifurcate in Texas: Rules, Deadlines, and Contents

A motion to bifurcate in Texas asks the court to split a trial into separate phases, usually liability first and damages second. Three legal paths exist: Rule 174(b) of the Texas Rules of Civil Procedure, which gives the judge discretion; Section 41.009 of the Civil Practice and Remedies Code, which is mandatory when a plaintiff seeks exemplary damages; and Chapter 72 of the same code, which is mandatory in commercial motor vehicle collision cases. Which path applies determines your deadline, what you have to prove, and what happens if the judge says no.

The Discretionary Path Under Rule 174(b)

Rule 174(b) lets a trial judge order separate trials of any claim, counterclaim, cross-claim, or individual issue.¹ Either side can move for it. The rule uses “may,” so the decision belongs to the judge, and the moving party has to show a unified trial would create real problems rather than theoretical ones.

Judges typically weigh three purposes:

Convenience for the parties, court, and witnesses.
Avoiding prejudice, such as keeping evidence of a defendant’s insurance or financial resources away from the jury during the liability phase.
Efficiency, particularly where a liability finding could eliminate any need to try damages.

Appellate courts review these rulings for abuse of discretion, which is a high bar. A denial under Rule 174(b) generally cannot be challenged until after final judgment.

Mandatory Bifurcation When Exemplary Damages Are Sought

Section 41.009 removes the judge’s discretion in any case where the plaintiff seeks exemplary (punitive) damages. On a defendant’s timely motion, the court “shall” bifurcate the trial, and this applies even when the case has more than one defendant.²

The first phase decides whether the defendant is liable for both compensatory and exemplary damages, plus the amount of compensatory damages. Evidence of the defendant’s net worth or financial condition stays out of this phase. If the jury finds exemplary-damages liability in phase one, the trial moves straight into a second phase focused only on the amount of the exemplary award.²

Mandatory Bifurcation in Commercial Vehicle Collision Cases

Chapter 72 of the Civil Practice and Remedies Code adds a second mandatory-bifurcation statute for lawsuits arising out of commercial motor vehicle collisions. On a defendant’s motion, the court “shall” bifurcate.³ Both individual driver defendants and their employers can invoke the statute; a Texas appellate court confirmed this in early 2026 after granting mandamus against a trial court that had limited it to employers.

The structure is similar to the exemplary-damages split. Phase one covers liability and compensatory damages. Phase two handles exemplary damages. Chapter 72 also carries a specific rule for employer liability: if the jury finds in phase one that an employee driver was negligent while operating the employer’s commercial vehicle, that finding can support claims against the employer, such as negligent entrustment, in phase two.³ The point is to keep inflammatory evidence about the trucking company’s safety record or hiring practices out of the room until basic negligence is established.

Filing Deadlines

Deadlines differ sharply among the three paths, and missing one can forfeit the right to bifurcate.

Rule 174(b) has no statutory deadline. Judges expect the motion well before trial, and filing on the eve of jury selection tends to draw a denial. Many courts address bifurcation at pretrial conferences, and local rules or scheduling orders often set firm cutoffs.
Section 41.009 requires the motion to be filed before voir dire begins, or by any earlier date set in a pretrial order under Rule 166. If the pretrial order sets a deadline and you miss it, the motion is untimely even if voir dire has not started.²
Section 72.052 requires the motion to be filed by the later of 120 days after the defendant files its original answer, or 30 days after the plaintiff files a pleading adding a new claim against that defendant.³

The Chapter 72 deadline is the earliest and strictest of the three. Defense counsel in commercial vehicle cases should calendar the 120-day window the day the answer is filed, because there is no late-filing exception.

What the Motion Should Contain

The motion needs the full case style (cause number, court, and party names) and a clear statement of the legal basis for the request. For a mandatory motion under Section 41.009 or Chapter 72, cite the statute and show that its prerequisites are met.

A Rule 174(b) motion needs more substance. Identify the specific claims or issues you want separated, propose a trial sequence, and connect the facts to the statutory factors of convenience, prejudice, or efficiency. Point to the particular evidence that would create prejudice if presented in the wrong phase, and explain concretely why separate trials would save time or resources. Vague assertions that a unified trial would be “confusing” rarely persuade.

Attach a proposed order. For exemplary-damages bifurcation, the order should reflect the two-phase structure Section 41.009 requires: phase one for liability and compensatory damages, phase two for the amount of exemplary damages.² A ready-to-sign order that matches the statute makes it easier for the judge to grant the motion cleanly.

Filing, Service, and Fees

Most Texas courts require electronic filing. The motion goes through the state e-filing system, which routes it to the district or county clerk. Under Rule 21 of the Texas Rules of Civil Procedure, every motion must be served on all other parties, and the e-filing system handles service electronically for registered attorneys.¹

Whether a filing fee applies depends on how the clerk categorizes the motion. Texas district courts charge an $80 consolidated fee ($35 local plus $45 state) on certain subsequent filings, but the statute lists specific triggers: counterclaims, cross-actions, interventions, motions for new trial, and similar filings.⁴ A standard bifurcation motion is not on that list, so it may not carry the fee. E-filing service providers charge their own transaction fees, which are typically modest. Check with the clerk if you’re unsure.

After filing, contact the court coordinator to schedule a hearing and give formal notice to opposing counsel within whatever timeframe the court requires. Some courts, including federal courts sitting in Texas, decide these motions on the papers without oral argument, so don’t count on arguing in person. The signed order becomes the blueprint for how trial will proceed.

If the Court Denies a Mandatory Bifurcation Motion

A denial under Rule 174(b) has to wait for post-judgment appeal, and abuse of discretion is a difficult standard to meet.

Denials of mandatory motions are different. Because Sections 41.009 and 72.052 use “shall,” a trial court that denies a timely, qualifying motion has no discretion to exercise. The remedy is a petition for writ of mandamus in the court of appeals, asking that court to order the trial judge to comply with the statute. Texas appellate courts have granted mandamus in this context, including a 2026 decision holding that Chapter 72 applies to individual driver defendants as well as employers. Mandamus has its own procedural requirements and is not automatic, but the mandatory statutory language makes it a real option. If your timely motion is denied, consult appellate counsel quickly: waiting until after a verdict may lead to a finding that the error was waived or harmless.
