Tex. Estates Code § 1203.056

(a) The court may remove a guardian under Section 1203.051(a)(6)(A) or (B) only on the presentation of clear and convincing evidence given under oath.

(b) Not later than the 30th day after the date the court signs the order of removal, a guardian who is removed under Section 1203.051(a)(6)(A) or (B) may file an application with the court for a hearing to determine whether the guardian should be reinstated.

(c) On the filing of an application under Subsection (b), the court clerk shall issue to the applicant, the ward, a person interested in the ward's welfare or estate, and, if applicable, a person who has control of the care and custody of the ward a notice stating:

(1) that an application for reinstatement has been filed;

(2) the name of the ward; and

(3) the name of the applicant for reinstatement.

(d) The notice required by Subsection (c) must cite all persons interested in the ward's welfare or estate to appear at the time and place stated in the notice if the persons wish to contest the application.

(e) The court shall hold a hearing on an application for reinstatement under this section as soon as practicable after the application is filed, but not later than the 60th day after the date the court signed the order of removal. If, at the conclusion of the hearing, the court is satisfied by a preponderance of the evidence that the applicant did not engage in the conduct that directly led to the applicant's removal, the court shall:

(1) set aside any order appointing a successor guardian; and

(2) enter an order reinstating the applicant as guardian of the ward or estate.

(f) If the court sets aside the appointment of a successor guardian under this section, the court may require the successor guardian to prepare and file, under oath, an accounting of the estate and to detail the disposition the successor has made of the estate property.
