Tex. R. App. P. 37.1

As amended through February 20, 2024
Rule 37.1 - On Receiving the Notice of Appeal

If the appellate clerk determines that the notice of appeal or certification of defendant's right of appeal in a criminal case is defective, the clerk must notify the parties of the defect so that it can be remedied, if possible. If a proper notice of appeal or certification of a criminal defendant's right of appeal is not filed in the trial court within 30 days of the date of the clerk's notice, the clerk must refer the matter to the appellate court, which will make an appropriate order under this rule or Rule 34.5(c)(2).
