The most common reasons for mail ballots to be rejected are that the voter’s signature did not compare to the voter’s signature on file or the voter didn’t sign the envelope. The Registrar of Voters will notify voters at least eight days before the election is certified and be given until two days before certification to resolve the issue. The Registrar of Voters must certify the results of this election no later than October 14, 2021.

Another common reason for ballots to be rejected is the ballot was received too late. Voters must return their voted ballot by 8 p.m. on September 14 at any polling location, mail ballot drop‑box or the Registrar of Voters office. Ballots that are mailed must be postmarked on or before Election Day – Tuesday, September 14 – and received by Tuesday, September 21.
