MAINE ABSENTEE BALLOTS

Who Can Absentee Vote in Maine?

Any registered voter may cast an absentee ballot instead of voting in person at the polling place. You do not need to have a specific reason or be unable to vote at the polls on election day to use an absentee ballot.

How Can I Acquire an Absentee Ballot?

Absentee ballots may be requested beginning 3 months before Election Day.

In Person:
You may vote absentee at the clerk’s office as soon as absentee ballots are available. Absentee ballots are available 30 to 45 days before the election at the municipal clerk’s office. You don’t need to complete an application if you vote in person at the clerk’s office.

By Mail:
A voter may request an absentee ballot from his/her local municipal clerk's office in person, by phone, or in writing. For contact information see:

A voter can also obtain an application for an absentee ballot online here. The application may be mailed, faxed, or delivered in person to the clerk's office.

Any voter may also make a request for an absentee ballot for a member of his/her immediate family (immediate family members include: spouse, parent, child, sister, brother, step-parent, stepchild, stepsister, stepbrother, mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law, daughter-in-law, guardian or former guardian).
A written request may be made for a third party (someone other than the voter or the voter's immediate family) to obtain and hand-deliver an absentee ballot.
