You got married, and you’re taking your wife’s name. Or you entered the witness protection program, and your name is now changed from Hu to Wu. Or you’ve just always felt more like a “Martha” than a “Ben.” You’ll have to be sure to change your name with the Social Security Administration before heading to the DMV.

Once you’ve taken care of that, allow 72 hours for processing and then get back to the DMV within 30 days, where you’ll provide your license and the paperwork that verifies the name change, as well as a completed Driver License Identification Card application and fee.

Just be grateful you’re not doing this in the olden days, because they used to also require that you fork over your first-born.
The DMV will then check over the ol’ interwebs to make sure that everything is on the up-and-up. They’ll snap a new photo, make sure your fingerprints haven’t changed, and get your autograph, and you’ll be all set. Good luck out there, Mr. or Mrs. Whatever Your Name Is.
