Can a notary public notarize their own signature?

A notary public is prohibited from notarizing their own signature due to the inherent conflict of interest that arises from doing so. Notarization involves acting as an impartial witness to the signing of a document; therefore, it is essential that the notary remains an objective third party. By notarizing their own signature, they would be unable to fulfill the necessary impartial role, undermining the integrity of the notarization process.

This regulation is in place to ensure that notarization maintains its purpose of verification and authentication, offering trust in official documents. Hence, the correct answer is that a notary public cannot notarize their own signature.
