Vital records; amendment of certificate or records; biological sex; effective date.

HB 1225 prohibits amendments to the biological sex designation on Oklahoma birth certificates to nonbinary options (like "X"). It requires that biological sex on amended birth certificates must remain strictly "male" or "female," banning any nonbinary symbols or designations. The bill directly affects individuals seeking to update their birth records to reflect a nonbinary gender identity after the initial issuance. The policy change becomes effective November 1, 2025, and applies to all future amendments under Oklahoma's vital records laws.
