Voter's oath or affirmation
The voter's oath or affirmation, formerly the freemen's oath, is a citizen's oath or affirmation taken during voter registration in the U.S. state of Vermont. In 2007, the law was amended to make it easier to administer this oath or affirmation; instead of being administered only by notaries public and similar officials, the oath may be administered by nearly anyone, including the applicant.
