Bill > HB477

This bill modifies Texas Health and Safety Code provisions regarding birth certificates, requiring that a child's biological sex be recorded as either male or female on birth certificates. The bill defines biological sex as determined by sex organs, chromosomes, or endogenous profile, and mandates that local registrars list this information on birth certificates. In cases where a child's biological sex is not clear at birth due to atypical or ambiguous sex organs or chromosomes, the birth certificate may be amended later when the sex is determined. The bill specifically restricts changes to a minor's biological sex on a birth certificate, allowing amendments only for correcting clerical errors, completing originally missing biological sex information, or addressing cases of initially ambiguous sex determination. These restrictions effectively prevent minors from changing their recorded biological sex on birth certificates except under very limited circumstances. The bill will take effect immediately if it receives a two-thirds vote in the Texas legislature, or on September 1, 2025, if it does not receive the required immediate voting threshold.
