Relating to proof of the identity of a child's parents in a suit affecting the parent-child relationship.

HB 1973 requires individuals filing family court cases involving parent-child relationships (like custody or adoption) to submit a certified copy of a child's birth certificate if available. If the birth certificate doesn't list both parents or isn't accessible, courts can request alternative proof from any party and must keep all submitted documents sealed for privacy. The bill exempts child support enforcement agencies (Title IV-D) from submitting birth certificates or related proof in their cases. This law applies to cases filed on or after September 1, 2025, and is now effective after being signed by the governor.
