Elec. Code, § 3111

If a military or overseas voter is unable to appear at their polling place because of being recalled to service after the seventh day prior to the date of the election, but before 5 p.m. on the day before the day of the election, they may appear before the elections official in the county in which the military or overseas voter is registered or, if within the state, in the county in which the voter is recalled to service. The elections official shall deliver to the voter a vote by mail ballot which may be voted in the elections official’s office or voted outside the elections official’s office on or before the close of the polls on the day of election and returned as are other vote by mail ballots. To be counted, the ballot shall be returned to the elections official’s office in person, by facsimile transmission, or by an authorized person on or before the close of the polls on the day of the election. If the military or overseas voter appears in the county in which the voter is recalled to service, rather than the county to which the voter is registered, the elections official shall coordinate with the elections official in the county in which the military or overseas voter is registered to provide the ballot that contains the appropriate measures and races for the precinct in which the military or overseas voter is registered.
