Which method of identifying a remote signer involves personal knowledge of the signer?

The method of identifying a remote signer that involves personal knowledge of the signer is personal knowledge of the signer itself. This approach entails that the notary has firsthand knowledge of the individual's identity, which does not rely on any third-party verification or identification documents. The notary can confirm the signer's identity because they have interacted with the signer directly in the past.

Utilizing personal knowledge allows for a more straightforward process, as it does not require additional methods of validation, such as presenting identification documents or using credible witnesses. In scenarios where a notary is familiar with the signer, this option can be efficient and effective, fostering a level of trust established through previous encounters.
