H.B. No. 917 amends Article 2A.105(b) of the Code of Criminal Procedure to allow district or county attorneys to participate as counsel in certain proceedings where they would otherwise be prohibited from acting adversely to the state. Specifically, the bill introduces a provision that permits these attorneys to serve as an attorney ad litem appointed under Chapter 262 of the Family Code, thereby expanding their role in legal proceedings. Additionally, the bill maintains the restriction that once an attorney ceases to be a district or county attorney, they cannot represent a party adversely to the state in any case where they previously served as counsel for the state.

The changes made by this Act will only apply to offenses committed on or after its effective date of September 1, 2025. For offenses committed prior to this date, the existing law will remain in effect, ensuring that any legal proceedings related to those offenses are governed by the rules that were in place at the time of the offense.
