How does a notary generally verify a signer's identity?

A notary generally verifies a signer's identity by examining identification documents and asking questions. This process is crucial to ensure that the individual signing a document is indeed who they claim to be. The examination of identification, such as a driver's license or passport, provides a tangible form of proof that includes a photograph and personal details that can be matched against the signer. Additionally, asking questions related to the document or the signer's situation further confirms their identity and their understanding of the transaction.

This approach is grounded in the need for diligence to prevent fraud and to maintain the integrity of notarized documents. It helps mitigate risks that could arise from accepting a signature from someone whose identity has not been properly verified. The other options suggest less reliable methods for identity verification, such as trusting the signer's word, checking social media profiles, or relying on personal acquaintances, which do not provide the necessary level of assurance required by notarial practices.
