FAQ

Q.

Do I need to sign the return envelope of my absentee ballot?

A.

Yes! Your absentee ballot cannot be counted unless you have signed the affidavit envelope that you return your ballot in. If we receive a ballot back that has not been signed we will attempt to contact you to get this fixed. Once contacted, you may decide to either:

  • Request a replacement ballot and return it by 8:00 p.m. on election day
  • Vote at the polls on election day
  • Sign the affidavit in person at the county auditor’s office by 8:00 p.m. on election day
