Birth certificate; prohibit change of sex on unless verified by medical records that sex of child is not what is shown on.

This Mississippi bill (HB 1375) would require medical verification from birth to change the sex designation on a birth certificate. It prohibits corrections unless proven to be an error via birth medical records or a physician's confirmation that the sex recorded at birth was incorrect. The law directly affects residents seeking to update their birth certificate sex marker. It would take effect July 1, 2026, but died in committee before becoming law.
