(a) In taking an acknowledgment, the notary public must determine, either from personal knowledge or from satisfactory evidence, that the person appearing before the notary and making the acknowledgment is the person whose true signature is on the instrument. (b) In taking a verification upon oath or affirmation, the notary public must determine, either from personal knowledge or from satisfactory evidence, that the person appearing before the notary and making the verification is the person whose true signature is on the statement verified. (c) In witnessing or attesting a signature, the notary public must determine, either from personal knowledge or from satisfactory evidence, that the signature is that of the person appearing before the notary and named therein. (d) A notary public has satisfactory evidence that a person is the person whose true signature is on a document if that person: (1) is personally known to the notary; (2) is identified upon the oath or affirmation of a credible witness personally known to the notary; or (3) is identified on the basis of identification documents. Identification documents are documents that are valid at the time of the notarial act, issued by a state agency, federal government agency, or consulate, and bearing the photographic image of the individual's face and signature of the individual. (e) A notary public or electronic notary public shall have no obligation to perform any notarial or electronic notarial act, and may refuse to perform a notarial or electronic notarial act without further explanation.
