What You Need to Know About Absentee Ballot Notary and Witness Signature Requirements

Each state has different rules regarding domestic absentee voting.  Some states impose additional requirements, like witness and/or notary signatures. We've got answers for you here.

Absentee voting, either by mail or by placing a ballot in a drop box, is more popular than ever. In 2020, 65 million voters successfully cast absentee ballots – that’s more than the number of in-person voters! Absentee voting makes life easier. And it’s a secure way to vote. 

  • Most Americans, we’re happy to report, like voting absentee: according to the Pew Research Center, 65% of voters favor access to no-excuse absentee voting, meaning you could cast a ballot from home even if nothing was physically preventing you from getting to the polling place.
  • At U.S. Vote Foundation we learned through our 2020 post-election survey, that the vast majority of voters – domestic (95%), overseas (85%), and military (90%) – were “satisfied” or “very satisfied” with their absentee voting experience.
  • Eight states – California, Colorado, Nevada, Oregon, Washington, Hawaii, Utah and (for general elections only, Vermont) – have successfully implemented "All Vote-by-Mail", in which all registered voters automatically receive a ballot in the mail to vote either by return mail, in-person at a local elections office/vote center, or at a drop box.


States that may require you to notarize your signature

In some states, your own signature is not enough to successfully cast a ballot. You must also obtain either a notary signature to either apply for an absentee ballot or submit a completed ballot.

  • Here’s how to find a notary.
  • Remember to bring your ID to the visit! You’ll be required to present ID, sign an attestation, and obtain the notary’s stamp and signature. 



    • All absentee ballot envelopes must be witnessed/signed by an official authorized to administer oaths such as a notary public, unless the voter is temporarily or permanently physically disabled. Temporarily or permanently physically disabled voters may have the ballot envelope witnessed by a person who is at least 18 years of age.

A Final Note About Absentee Voting Safeguards

Voting by absentee ballot has allowed states to maintain high levels of election security. Indeed, as the New York Times reported in 2020, “states that use vote-by-mail have encountered essentially zero fraud: Oregon, the pioneer in this area, has sent out more than 100 million mail-in ballots since 2000, and has documented only about a dozen cases of proven fraud.” As the Brennan Center for Justice notes, that amounts to “0.00001 percent of all votes cast.”

States using vote-by-mail, or those that permit absentee voting, safeguard their systems by matching the signature on the ballot with the one in the registration record, tracking bar codes on ballots, and conducting post-election audits, among other things. These methods, some of which have been employed for decades, keep elections safe and secure.
