A notary's role in witnessing signatures primarily involves ensuring that the signer understands the document being signed. This is crucial because one of the key responsibilities of a notary public is to prevent fraud and protect the integrity of the signing process. By confirming that the signer comprehends the implications of their actions and the content of the document, the notary helps ensure that the signer is entering into the agreement voluntarily and with full awareness of its consequences.

In this context, the other options do not accurately reflect the notary's responsibilities. Directing what the signers should write is not within the scope of a notary’s duties; rather, the notary should remain impartial and allow the signers to complete documents without interference. Additionally, although a notary may verify that the document appears lawful, they do not serve to judge the legality of the agreement itself, as this requires legal expertise beyond the notary's role. Offering legal advice on the document also falls outside a notary's purview, as they are not authorized to provide legal interpretations or counsel to the signers. Therefore, the validation of the signer’s understanding of the document is the key aspect of the notary's function in this scenario.
