Before a nomination document is officially filed, the county elections official must check that the signatures and, if needed, political party preferences match those on file. If a signature doesn't match or the party preference is incorrect, it's marked as "not sufficient." Once enough valid signatures are confirmed, further verification can stop.

This law requires that any nomination documents meant for the Secretary of State must be sent there by the county elections official within five days after they're submitted to the county. When sending these documents, the county official must also include a statement listing how many signatures on the nomination form are valid and haven’t been marked as insufficient.

This law outlines the form that a county elections official must use when reporting to the California Secretary of State how many people signed a petition for a candidate running in a primary election. The official has to fill in details like the county name, candidate's name, the office they're running for, the election date, and the number of valid signatures. They must also include the date and their signature, along with a deputy's signature if applicable, as a certification of the statement.

This section deals with verifying signatures on petitions that are used to avoid paying a filing fee. When there are 100 or more signatures, election officials can use a random sampling method to check them. If there are between 100 and 1,999 signatures, 100 of them will be checked. If there are 2,000 or more signatures, 5% will be examined. The validity rate from the sample is then applied to the entire petition.
