You must first complete the Absentee Ballot Application (Form ED-3) which is available in English and in Spanish.
The form can be obtained in person at the Town Clerk's Office or by going to: https://portal.ct.gov/SOTS/Election-Services/Voter-Information/Absentee-Voting.
Once your application is completed, it must be taken to the Westbrook Town Clerk's Office with your photo ID where you can obtain an absentee ballot.
