North Carolina General Statutes Chapter 163. Elections and Election Laws § 163-258.17. Prohibition of nonessential requirements

(a) If a voter's mistake or omission in the completion of a document under this Article does not prevent determining whether a covered voter is eligible to vote, the mistake or omission does not invalidate the document. Failure to satisfy a nonessential requirement, such as using paper or envelopes of a specified size or weight, does not invalidate a document submitted under this Article. In any write-in ballot authorized by this Article or in any vote for a write-in candidate on a regular ballot, if the intention of the voter is discernable under this State's uniform definition of what constitutes a vote, as required by the Help America Vote Act, 42 U.S.C. § 15481(a)(6), an abbreviation, misspelling, or other minor variation in the form of the name of a candidate or a political party shall be accepted as a valid vote.

(b) An authentication, other than the declaration specified in G.S. 163-258.13 or the declaration on the federal postcard application and federal write-in absentee ballot, is not required for execution of a document under this Article. The declaration and any information in the declaration may be compared against information on file to ascertain the validity of the document.
