This item tests the completeness requirement, which exists to stop a notarized document from being altered after the fact. A document presented with blank spaces in its material parts is incomplete on its face, and notarizing it would attach the notary's certificate and seal to an instrument whose terms could still change. The notary's duty is to decline until the signer completes the document, because any other course either transfers authorship to the notary or leaves a signed instrument open to later insertion. This is a face-of-the-document test: the notary is not judging whether the terms are wise, only whether the instrument is finished.
