In addition to knowing the signer, what relationship must the notary have with the credible witness?

The correct answer emphasizes that the notary must either know the credible witness personally or verify their identity through an identification document. This is crucial because the role of the credible witness is to provide assurance regarding the identity of the signer, ensuring that the notarization process is secure and legitimate. By knowing the witness personally or confirming their identity via ID, the notary can confidently trust the witness’s statements about the signer’s identity, which is essential for upholding the integrity of the notarization.

The other options present unrealistic or insufficient relationships that would not provide the necessary assurance of credibility. For instance, merely meeting someone online does not establish a reliable basis for their identity or character, and being a colleague does not guarantee the personal knowledge necessary to affirm the witness’s credibility in a legal context. A signed agreement with the witness may detail responsibilities but does not inherently validate the witness's legitimacy or knowledge of the signer. Thus, the requirement for a personal connection or verification through ID is vital to maintain trust and security in the notarization process.
