evidence: An absentee by mail ballot must be signed by both the voter and by one witness. A person who is a witness is allowed to serve as a witness for only one absentee ballot. [...] North Carolina does not require a copy of voter identification but does require the signature of a notary or witness on the return envelope of an absentee ballot. Marking of an absentee ballot must be witnessed by two people or one notary. The two witnesses must sign the ballot, provide address information, and certify that the voter is the registered voter that requested the absentee ballot. If witnessed by a notary public, the ballot can be notarized.
