Does anyone know what it takes to add a spouse to a vehicle title in Florida?

I have searched the internet and Florida DMV and no one has the answer.|||IT HAS BEEN SOME YEARS SINCE I LIVED IN JACKSONVILLE BUT UNLESS THINGS HAVE CHANGRED IN THE LAST 10 YEARS, ALL YOU NEED IS STATE ID OR DRIVER,S LICENSE AND PROOF OF ADDRESS,YOU MAY EVEN BE ABLE TO GET IT DONE ON LINE|||not sure why you would want to. If you put it in both your names she now owns half of what was yours free and clear once upon a time. Im just thinking if things don't work out or something.
