Why is it essential for the signer's presence to be required during notarization?

The requirement for the signer's presence during notarization is crucial for maintaining the authenticity of the notarial act. This process ensures that the notary can verify the identity of the signer and confirm their willingness to sign the document. By being present, the signer is actively participating in the transaction, which helps prevent fraud and coercion. The notary public takes an oath to be impartial and act in accordance with the law, and having the signer present supports the integrity of this role by allowing the notary to assess the situation, ask pertinent questions, and establish that the signer understands the contents and implications of the document they are signing.

In contrast, other options do not capture the primary purpose of ensuring the authenticity. While speeding up the process or accommodating multi-person transactions may be benefits in some contexts, they do not address the fundamental necessity of verifying the signer's identity and intent. Moreover, the notion that signed documents alone are enough neglects the core principle of notarization, which rests on the assurance that the signature is legitimate and made voluntarily under circumstances confirmed by the notary.
