New Mexico Notary Public Exam

An acknowledgment requires the signer to sign in the notary's presence, while witnessing does not. Witnessing a signature requires the signer to take an oath, but an acknowledgment does not. The notary must always know the contents of the document for an acknowledgment, but not for witnessing a signature. In an acknowledgment, the signer declares they signed willingly; in witnessing, the notary certifies they observed the person signing.
