A notary closing agent, or notary signing agent, ensures that all legal documents during a property transaction get signed and delivered to the required authorities. Your duties include acting as a witness during the signing of these documents, as a home loan cannot proceed without the stamp of a notary closing agent. During the signing process, you verify and record the identity of each person involved in the transaction. You typically handle your responsibilities as an independent contractor, though some closing agents work with title companies or real estate lawyers. As a licensed notary public, you can perform other services, such as witnessing legal documents.
