Texas Code of Criminal Procedure - CRIM P Art. 45.0426. Filing Bond Perfects Appeal

(a) When the appeal bond has been filed with the justice or judge who tried the case not later than the 10th day after the date the judgment was entered, the appeal in such case shall be held to be perfected.

(b) If an appeal bond is not timely filed, the appellate court does not have jurisdiction over the case and shall remand the case to the justice or municipal court for execution of the sentence.

(c) An appeal may not be dismissed because the defendant failed to give notice of appeal in open court. An appeal by the defendant or the state may not be dismissed on account of any defect in the transcript.
