What does a Notary serve as in the context of official documents?

In the context of official documents, a Notary serves primarily as a witness to the signing of the document. The main role of a Notary is to verify the identity of the signers and ensure that they are signing the document willingly and without any undue pressure. This process helps prevent fraud and enhances the integrity of the signed documents. The Notary's presence lends authority to the document, providing assurance that the signatures are authentic and the individuals have understood what they are signing.

While other roles mentioned in different options may seem relevant, they don't accurately represent the core function of a Notary. A Notary is not responsible for providing legal advice regarding the content of the document, maintaining records of all transactions, or mediating disputes. Each of these responsibilities falls under the domain of other professionals, such as lawyers or financial institutions, rather than that of a Notary.
