Executive Summary:

Effective March 1, 2026, summary judgment practice in Texas has been fundamentally reshaped by a combination of legislative mandates and a complete rewrite of Texas Rule of Civil Procedure 166a. The era of indefinite delays is over; courts are now subject to statutory deadlines for hearing and ruling on dispositive motions. For practitioners, the most critical change is a complete reversal of how briefing deadlines are calculated. Deadlines are no longer anchored to a future hearing date. Instead, the clock for filing a response starts the moment a motion for summary judgment is filed. This new framework, which includes a 21-day response deadline and a 7-day reply deadline, compresses the entire lifecycle of a motion and demands significant adjustments to litigation workflows, docket management, and case preparation strategies.

What Changed: The Statutory and Rule Sources

The new summary judgment framework is built on three pillars: two statutes passed by the Texas Legislature and a completely rewritten rule of procedure from the Texas Supreme Court. Understanding how these authorities interact is essential.

1. Senate Bill 293 (Effective September 1, 2025): This legislation created Texas Government Code § 23.303, which for the first time imposed mandatory deadlines on district, statutory county, and business courts to hear and rule on summary judgment motions. It established a 90-day deadline for a court to rule after a motion is heard or submitted.

   
   

2. House Bill 16 (Effective December 4, 2025): This bill amended Government Code § 23.303, tightening the timeline further. It added a requirement that courts must set a motion for hearing or submission within 60 days of the motion's filing date, a deadline that can be extended to 90 days only for good cause or with the movant's consent.

   
   

3. Amended Rule 166a (Effective March 1, 2026): To implement these statutory mandates and modernize summary judgment procedure, the Texas Supreme Court issued an order completely rewriting Rule 166a. This new rule establishes the motion-filing-based briefing schedule and formalizes procedures for replies, continuances, and motion titling. The Court's comment to the 2026 change explicitly states the rewrite is intended to implement the new statutory requirements.

   
   

Crucially, the deadlines in the Government Code are legislative mandates that cannot be altered by procedural rule. The new Rule 166a operates within the strict timelines set by the Legislature.

Compare Old v. New Procedure: A Fundamental Shift in Timing

The most significant change for practitioners is the complete reversal of how summary judgment deadlines are calculated. The old, familiar hearing-anchored timeline has been replaced by a new filing-triggered schedule.

The Old Framework: Working Backward from a Hearing Date

Under the former Rule 166a, all deadlines were anchored to the date of the summary judgment hearing or submission. This meant no deadlines were triggered until a court set the motion for consideration. The process was entirely reactive:

• Motion Deadline: The motion had to be filed at least 21 days before the hearing.

• Response Deadline: The non-movant's response was due no later than 7 days before the hearing. This dependency on the hearing date was a core principle of Texas summary judgment practice.

• Reply Deadline: The former rule prescribed no deadline for a reply. Filing was a matter of custom and court discretion, not rule.

• Ruling Deadline: There was no deadline for the court to rule, which allowed motions to languish for months or even years.

  
  

The New Framework: Moving Forward from the Filing Date

Effective March 1, 2026, the new Rule 166a flips the entire timeline on its head. All briefing deadlines now run forward from the moment the motion for summary judgment is filed, creating an immediate and predictable schedule.

• Day 0: Motion is Filed. The clock for all subsequent briefing starts immediately.

  
  

• Day 21: Response is Due. The non-movant must file any response within 21 days after the motion is filed.

  
  

• Day 28: Reply is Due. The movant may file a reply within 7 days after the response is filed.

  
  

• Day 35: Earliest Hearing Date. A hearing or submission cannot be set any earlier than 35 days after the motion was filed.

• Day 60--90: Hearing Must Be Set. Under the Government Code, the court must set the motion for hearing or submission within 60 days of filing (or 90 days with good cause or movant consent).

  
  

• Within 90 Days of Hearing: Ruling is Due. The court is statutorily required to issue a written ruling within 90 days of the hearing or submission date.

  
  

This shift cannot be overstated. Under the old system, a non-movant's response clock did not start until a hearing was set. Under the new system, the 21-day response clock begins ticking the instant the motion hits the docket, requiring significantly more proactive case management.

Detailed New Timeline and Operative Deadlines

To effectively manage litigation under the new framework, practitioners must internalize a precise, forward-looking calendar. The entire lifecycle of a summary judgment motion, from filing to ruling, is now governed by a series of interconnected deadlines set by both the Texas Government Code and the revised Rule 166a.

• Day 0: Motion Filed. The timeline is triggered the moment a party files a motion for summary judgment. Under new Rule 166a(c), upon filing, the clerk must "immediately call the motion to the court's attention," and the court must "promptly set the motion for submission or a hearing".

  
  

• Day 21: Response Due. The non-movant's deadline to file a response is "within 21 days after the motion is filed," unless the court grants leave for an extension. This clock starts automatically and is not dependent on a hearing being set.

  
  

• Day 28: Reply Due. The movant has the option to file a reply. The deadline for the reply is "within 7 days after the response is filed," again subject to leave of court. Replies are restricted and may not raise new summary judgment grounds.

  
  

• Day 35: Earliest Possible Hearing. A court cannot hold a hearing or set a submission date "within 35 days after the motion's filing". This creates a protected period for the completion of the 21-day response and 7-day reply cycle.

  
  

• By Day 66: Statutory Hearing/Consideration Deadline. Under Texas Government Code § 23.303, the court must hear oral argument on the motion, or consider the motion without oral argument, no later than the 45th day after the date the response is filed; with a Day 21 response, this outer limit will generally fall around Day 66.

  
  

• Day 60: Deadline to Set a Hearing/Submission. As mandated by statute and incorporated into Rule 166a(g)(1), the court is required to set the motion for a hearing or written submission within 60 days after the motion's filing. This can be extended to 90 days if the movant agrees, for good cause shown, or if the court's docket requires it.

  
  

• Within 45 Days After Response: Hearing or Consideration Deadline. Under Texas Government Code § 23.303(a), the court must hear oral argument on a motion for summary judgment, or consider the motion without oral argument, no later than the 45th day after the date the response is filed. This statutory 45-day clock operates in tandem with the rule-based briefing schedule and the 60-/90-day hearing-setting requirement.

  
  

• The Ruling: Within 90 Days of Hearing/Submission. Both Texas Government Code § 23.303 and new Rule 166a(i) impose a mandatory 90-day deadline for the court to sign and file a written ruling after the hearing or submission date.

  
  

• Critical Docket Entries. The court must record in the docket the specific date the motion was heard or submitted. This entry is not merely administrative; it is the official trigger for the 90-day ruling clock and is essential for enforcement and accountability.

  
  

• Effect of Withdrawal. A withdrawn motion pauses the statutory timeline. New Rule 166a(f) requires that a withdrawal be formally filed and identify the original motion's filing date. If the motion is refiled, the timeline resets, preventing procedural gamesmanship.

Practical implications and immediate practice changes

The new framework requires immediate adjustments to internal workflows for all litigation participants.

For All Litigants and Support Teams:

• Update Docketing Systems: Calendaring software must be reconfigured to calculate the 21-day response and 28-day reply deadlines forward from the motion filing date. Relying on a hearing date to trigger deadlines is no longer viable.

  
  

• Revise Templates: All summary judgment motion and response templates should be updated to reflect the new requirements, including mandatory titles and the cover-page placement for oral argument requests.

  
  

For Movants

• Use Mandatory Titles: Every motion must be explicitly titled as a "Traditional Motion for Summary Judgment," "No-Evidence Motion for Summary Judgment," or "Combined Motion for Summary Judgment". While an incorrect title is not grounds for denial, using the correct title is a mandatory requirement of the new rule.

  
  

• File Complete Motions: With courts on a strict statutory clock, motions must be complete and ready for ruling upon filing. Placeholder motions that are supplemented later will be met with less tolerance.

  
  

• Submit a Proposed Order: New Rule 166a(g)(3) requires parties to submit a proposed order before the hearing or submission date. A well-drafted order that accurately reflects the grounds for judgment assists a time-pressured court.

  
  

• Respect Reply Limitations: Replies must not raise new summary judgment grounds. The new Rule 166a(e)(2) expressly prohibits this practice, with the sole exception of addressing an amended pleading filed in response to the motion. Sandbagging in the reply is now officially barred.

  
  

For Non-Movants

• Aggressively Monitor Dockets: Since the 21-day response clock begins immediately upon filing, it is critical to have a system for daily docket monitoring. Missing a filing notice by even a few days can severely compromise preparation time.

  
  

• Begin Evidence Assembly Immediately: The 21-day response window requires that the work of gathering affidavits, identifying deposition excerpts, and authenticating documents begins the moment a motion is filed, or even earlier if a motion is anticipated.

  
  

• Utilize the Formal Continuance Procedure: If evidence essential to the opposition is not yet available, the non-movant must file an affidavit or declaration specifying the reasons. Under Rule 166a(d)(3), the court has broad discretion to extend the response deadline, deny the motion without prejudice to allow for more discovery, or issue another appropriate order.

  
  

• Place Hearing Requests on the Cover: A request for oral argument must appear on the cover of the response to be properly presented under Rule 166a(d)(2).

  
  

Citations, Resources, and Recommended Further Reading

For practitioners seeking to verify these changes and conduct deeper research, the following primary and secondary sources are essential.

Statutes and Rules

• Texas Government Code § 23.303: The core statutory text imposing mandatory deadlines on courts. Review the versions as amended by both SB 293 and HB 16 to understand the full framework.

• Order Regarding Rule 166a, Texas Rules of Civil Procedure: Order Granting Preliminary Approval of Amendments to Tex. R. Civ. P. 166a, Misc. Docket No. 25-9106 (Tex. Dec. 30, 2025). This preliminary approval order reproduces the full text of the proposed rewritten rule and the Supreme Court’s 2026 comment explaining that the changes are intended to implement Texas Government Code § 23.303 and modernize summary judgment practice. The Court has invited public comment and stated that it expects to issue a final adoption order making the amendments effective March 1, 2026, so practitioners should consult that final order, together with Misc. Docket No. 25-9106, once it is released.
