It is very important to keep your signature updated, as it is used to verify Vote-By-Mail ballots and petitions. An outdated signature, if it differs significantly from your current signature, may result in your Vote-By-Mail ballot or petition not being accepted. You may update your signature on file with our office at any time using a Florida Voter Registration Application, which can be obtained from here https://registertovoteflorida.gov/home, or at our office, or any other voter registration agency.
