Vote an Absentee Ballot in Person

You may vote an absentee ballot in person at the Election Authority’s office. Voting begins six weeks before an election and continues until 5 p.m. the day before the election.

Absentee Ballot for a Family Member

A family member within the second degree may apply at the Election Authority’s office in person for the ballot to be mailed to the family member.

Applying for an Absentee Ballot by Mail

You will need to request a ballot in writing, and you must reapply for a new ballot before each election. If you have registered to vote by mail, proof of identification is required before an absentee ballot may be mailed to you. After you receive your ballot, insert the voted ballot inside the provided return envelope, and a notary must witness your signature on the affidavit on the outside of the envelope. Notary officials may perform this service free of charge for absentee voters.

Written Requests

Written requests for absentee ballot must be received in the Election Authority’s office no later than 5 p.m. the second Wednesday before any election. You may download, complete and return the November 2020 Absentee Ballot Application (PDF) for St. Charles County, Missouri, or your request must contain the following information:

  • Your full name
  • Address where you live
  • Address where you would like the ballot to be mailed (if different)
  • Reason for voting absentee
  • The date of the election
  • Your political party preference, if you are applying for an August Primary Ballot
  • Your signature

Individuals with a Disability

Individuals with a disability have several options for voting:

  • Curbside voting assistance is available at all of our polling locations on election day.
  • Vote on a touch-screen unit (aka OVI) at your polling location (in federal elections) or at the St. Charles County Election Public Service Center (in all elections).
  • Request to have your name placed on a permanently disabled voter’s list as set out below. After being placed on this list, you will automatically receive a Permanently Disabled Absentee Ballot Application (PDF) before every election that you are eligible to vote in. You must complete this application and return it to our office, and then you will be sent an absentee ballot. Then you must vote the ballot, place it inside the return envelope, complete the envelope by signing your name and then mail it back to us. You are exempt from needing your signature notarized.
  • You will continue to receive a permanently disabled absentee ballot application before each subsequent election until you request to have your name removed from this list. Remember, you must complete the application and return it to us each time in order to receive your ballot.

Caregiver of a permanently disabled voter:

  • If you are a caregiver of a permanently disabled voter, you may download, complete and return an November 2020 Absentee Ballot Application (PDF). You must reapply for a new ballot before each election. Caregivers are exempt from needing their signature notarized.

Military & Overseas Civilian

You may request an absentee ballot from the commanding officer or by contacting the Election Authority. To vote on all ballot issues, you must be a registered voter or provide proof of identification. You may download, complete and return the Federal Post Card Application Form (PDF). This form may also be used for an overseas civilian of the U.S. who claims an address within St. Charles County, Missouri.

Affidavit Envelope

The affidavit envelope does not have to be notarized for anyone requesting an absentee ballot because of sickness or disability, including a person who is primarily responsible for the physical care of a person who is incapacitated or confined due to illness or disability, or a resident of the State of Missouri or immediate family living with them who resides outside the boundaries of the United States or who is in active duty with the armed forces of the United States.


If you are hospitalized, within our county, after 5 p.m. on the Wednesday prior to an election, you may call the Election Authority’s office to request an absentee ballot. A bipartisan team of election judges will be sent to your hospital room to allow you to vote.
