Relating to a suit for possession of or access to a child by a grandparent.

HB 2645 amends Texas Family Code to change procedures for grandparent access to grandchildren. It requires courts to appoint a guardian ad litem for the child in grandparent custody suits and removes the need for expert testimony when proving that denying access would significantly harm the child’s well-being. The bill allows courts to grant access if a grandparent overcomes the presumption that parents act in a child’s best interest by showing denial would cause harm (by a preponderance of evidence), while still requiring at least one biological or adoptive parent to retain parental rights. This directly affects grandparents seeking access, children involved in such suits, and courts handling these cases under Family Code Sections 107.024 and 153.433.
