Ballot Signature Verification Statements and Instructions
May 4, 2021 Special Mail Ballot Election

Unsigned Ballot Statement

If you did not sign the return envelope as required by California Election Code §3011, you will be mailed the Unsigned Ballot Statement form.

Please read the instructions before you fill out this form. Return this form by 5 p.m. on June 1, 2021. 

If you are no longer able to sign the envelope on your own, you can make a “mark” and have it witnessed by a person over the age of 18 for this election. Your witness’ name and signature should appear next to the mark and be noted as witness. For future elections, you can re-register to vote with your mark on file as your legal signature. If you are not able or willing to make a mark, you may re-register using a signature stamp.

Signature Verification Statement

If your signature on the envelope does not match the signature in your voter registration record, you will be mailed the Signature Verification Statement.

Please read the instructions before you fill out this form. Return this form no later than 5 p.m. on June 1, 2020.
