FAQ

Q.

What is a provisional ballot?

A.

If a voter’s eligibility is in question on Election Day they are allowed to cast a provisional ballot. After the voter marks their ballot and returns it to the poll worker, the voter is required to provide the necessary identification or documentation to the Auditor’s Office by noon on the following Monday.

If it is determined that you do have the right to vote in the precinct in which you voted, your ballot will then be counted and included in the final vote total.
