Tex. R. Civ. P. 166a

As amended through February 20, 2024
Rule 166a - Summary Judgment
(a)For Claimant. A party seeking to recover upon a claim, counterclaim, or cross-claim or to obtain a declaratory judgment may, at any time after the adverse party has appeared or answered, move with or without supporting affidavits for a summary judgment in his favor upon all or any part thereof. A summary judgment, interlocutory in character, may be rendered on the issue of liability alone although there is a genuine issue as to amount of damages.
(b)For Defending Party. A party against whom a claim, counterclaim, or cross-claim is asserted or a declaratory judgment is sought may, at any time, move with or without supporting affidavits for a summary judgment in his favor as to all or any part thereof.
(c)Motion and Proceedings Thereon. The motion for summary judgment shall state the specific grounds therefor. Except on leave of court, with notice to opposing counsel, the motion and any supporting affidavits shall be filed and served at least twenty-one days before the time specified for hearing. Except on leave of court, the adverse party, not later than seven days prior to the day of hearing may file and serve opposing affidavits or other written response. No oral testimony shall be received at the hearing. The judgment sought shall be rendered forthwith if (i) the deposition transcripts, interrogatory answers, and other discovery responses referenced or set forth in the motion or response, and (ii) the pleadings, admissions, affidavits, stipulations of the parties, and authenticated or certified public records, if any, on file at the time of the hearing, or filed thereafter and before judgment with permission of the court, show that, except as to the amount of damages, there is no genuine issue as to any material fact and the moving party is entitled to judgment as a matter of law on the issues expressly set out in the motion or in an answer or any other response. Issues not expressly presented to the trial court by written motion, answer or other response shall not be considered on appeal as grounds for reversal. A summary judgment may be based on uncontroverted testimonial evidence of an interested witness, or of an expert witness as to subject matter concerning which the trier of fact must be guided solely by the opinion testimony of experts, if the evidence is clear, positive and direct, otherwise credible and free from contradictions and inconsistencies, and could have been readily controverted.
(d)Appendices, References and Other Use of Discovery Not Otherwise on File. Discovery products not on file with the clerk may be used as summary judgment evidence if copies of the material, appendices containing the evidence, or a notice containing specific references to the discovery or specific references to other instruments, are filed and served on all parties together with a statement of intent to use the specified discovery as summary judgment proofs: (i) at least twenty-one days before the hearing if such proofs are to be used to support the summary judgment; or (ii) at least seven days before the hearing if such proofs are to be used to oppose the summary judgment.
(e)Case Not Fully Adjudicated on Motion. If summary judgment is not rendered upon the whole case or for all the relief asked and a trial is necessary, the judge may at the hearing examine the pleadings and the evidence on file, interrogate counsel, ascertain what material fact issues exist and make an order specifying the facts that are established as a matter of law, and directing such further proceedings in the action as are just.
(f)Form of Affidavits; Further Testimony. Supporting and opposing affidavits shall be made on personal knowledge, shall set forth such facts as would be admissible in evidence, and shall show affirmatively that the affiant is competent to testify to the matters stated therein. Sworn or certified copies of all papers or parts thereof referred to in an affidavit shall be attached thereto or served therewith. The court may permit affidavits to be supplemented or opposed by depositions or by further affidavits. Defects in the form of affidavits or attachments will not be grounds for reversal unless specifically pointed out by objection by an opposing party with opportunity, but refusal, to amend.
(g)When Affidavits Are Unavailable. Should it appear from the affidavits of a party opposing the motion that he cannot for reasons stated present by affidavit facts essential to justify his opposition, the court may refuse the application for judgment or may order a continuance to permit affidavits to be obtained or depositions to be taken or discovery to be had or may make such other order as is just.
(h)Affidavits Made in Bad Faith. Should it appear to the satisfaction of the court at any time that any of the affidavits presented pursuant to this rule are presented in bad faith or solely for the purpose of delay, the court shall forthwith order the party employing them to pay to the other party the amount of the reasonable expenses which the filing of the affidavits caused him to incur, including reasonable attorney's fees, and any offending party or attorney may be adjudged guilty of contempt.
(i)No-Evidence Motion. After adequate time for discovery, a party without presenting summary judgment evidence may move for summary judgment on the ground that there is no evidence of one or more essential elements of a claim or defense on which an adverse party would have the burden of proof at trial. The motion must state the elements as to which there is no evidence. The court must grant the motion unless the respondent produces summary judgment evidence raising a genuine issue of material fact.
