Relating to the definitions of child abuse and neglect and the temporary emergency jurisdiction of a court in this state over a child at risk of receiving certain prohibited gender transitioning or gender reassignment procedures or treatments.

HB 3478 amends Texas Family Code to expand court emergency jurisdiction when a child is at risk of receiving certain gender transition or reassignment procedures. It defines such treatments as potentially constituting child abuse under Section 261.001(1)(C) and allows courts to intervene immediately if a child is present in Texas and at risk of these prohibited treatments under Health and Safety Code Section 161.702. The bill directly affects minors, parents, and medical providers involved in gender-affirming care for children. Key provisions establish temporary court authority to protect children from these specific medical treatments without requiring prior abuse findings. The legislation focuses on defining legal standards for court intervention rather than creating new medical restrictions.
