Your signature is used to check vote-by-mail ballots, petitions and other election-related documents that require a valid voter signature. For vote-by-mail voters, your signature on file at the time your ballot is received in the elections office is the one that will be used to verify your signature on the ballot certificate envelope.
You can update your signature any time by submitting a completed Florida Voter Registration Application (English PDF or Spanish PDF) in person or by mail to the supervisor of elections. Just stop by or call one of three locations listed below for assistance or for more information.
