Detailed Explanation
Authentication and certified copies are different concepts. In “Definitions and General Terms,” “Authentication (Notarial)” is the county clerk’s certificate verifying the authority of the notary public to act, tied to Executive Law §133, while a certified copy is a copy of a public record certified by the custodian of the original. Not to be confused with each other, one authenticates the notary’s authority and the other certifies a public record copy.
