Cure My Ballot
Curing Ballots
Every valid vote matters, and sometimes a simple error on your Vote by Mail Ballot envelope can prevent your ballot from being counted. Curing is the process that lets you fix certain problems so your ballot can still be counted.
What Is Ballot Curing?
Ballot curing is the opportunity for a voter to correct specific errors on a Vote by Mail Ballot envelope after it has been submitted. The most common reasons a ballot may require curing are:
- Missing signature: the ballot envelope was not signed.
- Signature mismatch: the signature on the envelope does not match the signature on file.
In California, election officials compare the signature on the ballot envelope with the signature(s) on file. If there’s a missing or mismatched signature, the Registrar of Voters' office will notify you and give you a chance to cure the issue before a specified deadline.
How You’ll Be Notified
If your ballot has a curable issue, the Registrar of Voters will send you a notice by mail (and possibly by email or phone, if provided on the affidavit of registration) explaining the problem and what you need to do next. It’s important to respond as soon as possible.
Steps to Cure Your Ballot
1. Read your notice carefully. Your notice will tell you why your ballot couldn’t be counted and what form you need to complete.
2. Complete the required form. The Signature Verification Statement and Instructions Form allows you to provide your signature so our office can verify it against your registration records.
