God, I wish it was that easy when I changed my name and gender… and that was in California! My understanding is CA doesn’t require this anymore, but after I got my court order I had to get my doctor to fill out this form certifying me as a Real Transgender before the DMV would update shit. And this wasn’t in the 90s or anything, it was less than a decade ago. I consider myself lucky that the requirement to publish an ad in the paper announcing your name change was removed before I got mine done.
