It is always your right to vote on a paper affidavit ballot.
Affidavit ballots, also known as provisional ballots, are used when you believe yourself eligible to vote but cannot submit a regular ballot. For example, your name is not listed in the poll book, or your address has changed but your local board of elections did not update your file. If your name is not on the list, or your signature is missing, you have a right to vote by a paper “affidavit ballot.”
You will be asked to sign an oath saying you are registered, mark a paper ballot, and seal it in an envelope. Elections officials will later check their records to see if you are registered and if you were at the right poll site. If yes, your vote will be cast. If not, you will receive a notice.
If you have questions, ask the poll worker for a “voting rights” flyer; they are required to have one. The flyer will also tell you about your right to get a court order to vote on a machine.
