Signatures can change over time—because of age, illness, injury, or just natural changes in handwriting. That’s normal. But elections offices still compare your current
- signature to the one on your voter record to confirm it’s really you.
- Your signature is used to verify important election documents

The signature on your voter record is used to verify your signature on:

• the certificate for a Vote-by-Mail ballot

• a provisional ballot

• a candidate petition

• an issue petition

• any signed request to get a ballot or make certain changes to your voter record

What can happen if it isn’t updated

If the signature on your ballot envelope or petition doesn’t match the signature on file, the ballot/petition may not count (or the requested change may not be processed).

Good news: you can update it anytime

Signature updates can be made at any time. In Florida, the standard way to update your signature is to submit a voter registration application (as an update). 

If a Vote-by-Mail signature is flagged

Florida also has a process to fix (“cure”) certain Vote-by-Mail signature issues by submitting a Vote-by-Mail Ballot Cure Affidavit with a copy of ID by the state deadline after the election.
