You cannot use the "personally known" method to identify a signer if what condition applies?

The "personally known" method allows a notary to identify a signer based on their prior acquaintance with the signer. This method relies on the relationship and familiarity between the notary and the signer. In the case where a signer has only been recently met, the notary does not have an established relationship or enough knowledge of the signer's identity and character. Therefore, this situation does not satisfy the requirements for the "personally known" method, as it lacks the necessary depth of familiarity.

Conversely, a long-time acquaintance would provide sufficient assurance of identity. Presenting a valid state ID or a birth certificate also demonstrates a valid method of identification. Thus, those options ensure that the notary can verify the identity of the signer according to established protocols.
