Just curious. But how can you change your gender on your driver's license?

My friend and I are currently talkin on the phone and she saw a segment where a guy got a sex change and he was able to change his gender on his driver's license and the state allowed it. This was on the DISCOVERY card.Just curious. But how can you change your gender on your driver's license?
It's purely a matter of state law as to what evidence of change of gender -- mistake, surgery or otherwise -- or perhaps self-declaration, is required for amendment of birth certificate, licenses and other documentation.



New York State just announced acceptance of self-declaration for birth certificate amendment.Just curious. But how can you change your gender on your driver's license?
It probably had a note from it's sex-change doctor.
show the completion papers to the drivers license company and that should be enough because the state may be sued if they do not comply.i also read about this case and the doctor and hospital assisted in clearing the way to change his gender on all forms and bills.
