For Immediate Release

Deadline for voters to ‘cure’ ballot signature issues is March 27

SANTA ROSA, CA | March 22, 2024

Voters whose signatures were missing or mismatched on ballot envelopes for the March 2024 primary election have until 5 p.m. Wednesday, March 27 to submit completed signature “cure” forms to the Sonoma County Registrar of Voters Office, according to Deva Marie Proto, Sonoma County Clerk-Recorder-Assessor-Registrar of Voters.

Every election, county staff devote hundreds of hours to checking signatures on ballot envelopes. Each voter whose ballot envelope is missing a signature or has a signature that does not sufficiently compare to the signature(s) in that voter’s file is mailed a signature “cure” form. The form, if signed and returned to the Registrar of Voters Office before the March 27 deadline, allows the ballot to be counted and included in the final official certified election results.

Voters with a missing or challenged signature who lost or did not receive a signature “cure” form can download and print one by going to Click on the “Forms” option on the menu on the left, scroll down to the “Vote-by-Mail Signature Issues” heading, and click on either “Unsigned Ballot Statement” or “Signature Verification Statement” (see screenshot below). Please note that the form must be printed and signed by hand; digital signatures are not accepted.
