Tex. Code of Criminal Procedure § 39.025

(a) In this article:

(1) "Disabled person" means a person with a disability as defined by Section 3, Americans with Disabilities Act (42 U.S.C. 12102).

(2) "Elderly person" means a person 65 years of age or older.

(b) The court shall order the attorney representing the state to take the deposition of an elderly or disabled person who is the alleged victim of or witness to an offense not later than the 60th day after the date on which the state files an application to take the deposition under Article 39.02.

(b-1) On the motion of either party, the court may order the attorney representing the state to take the deposition of an elderly or disabled person by video recording. The person operating the video recording device must be available to testify regarding the authenticity of the video recording and the taking of the deposition in order for the video recording to be admissible.

(c) The attorney representing the state and the defendant or the defendant's attorney may, by written agreement filed with the court, extend the deadline for the taking of the deposition.

(d) The court shall grant any request by the attorney representing the state to extend the deadline for the taking of the deposition if a reason for the request is the unavailability, health, or well-being of the victim or witness.

(e) The Texas Rules of Civil Procedure govern the taking of the deposition, except to the extent of any conflict with this code or applicable court rules adopted for criminal proceedings, in which event this code and the rules for criminal proceedings govern. The attorney representing the state and the defendant or defendant's attorney may agree to modify the rules applicable to the deposition by written agreement filed with the court before the taking of the deposition.

(f) If a defendant is unavailable to attend a deposition because the defendant is confined in a correctional facility, the court shall issue any orders or warrants necessary to secure the defendant's presence at the deposition. The sheriff of the county in which a deposition under this subsection is to be taken shall provide a secure location for the taking of the deposition and sufficient law enforcement personnel to ensure the deposition is taken safely. The state's application to take a deposition or notice of deposition is not required to include the identity of any law enforcement agents the sheriff assigns to the deposition and may not serve as a basis for the defendant to object to the taking of the deposition.

(g) If a defendant is unavailable to attend a deposition for any reason other than confinement in a correctional facility, the defendant or defendant's attorney shall request a continuance from the court. The court may grant the continuance if the defendant or defendant's attorney demonstrates good cause for the continuance and that the request is not brought for the purpose of delay or avoidance. A defendant's failure to attend a deposition or request a continuance in accordance with this subsection constitutes a waiver of the defendant's right to be present at the deposition.
