Tex. Gov't Code § 24.002

If a district judge determines on the judge's own motion that the judge should not sit in a case pending in the judge's court because the judge is disqualified or otherwise should recuse himself or herself, the judge shall enter a recusal order, request the presiding judge of that administrative judicial region to assign another judge to sit, and take no further action in the case except for good cause stated in the order in which the action is taken. A change of venue is not necessary because of the disqualification of a district judge in a case or proceeding pending in the judge's court.
