A more thorough explanation:

A notarial register is a sequential record of notarial transactions kept by a notary public. It is usually a bound book that lists the date, time, and type of each official act, the type of instrument acknowledged or verified before the notary, the signature of each person whose signature is notarized, the type of information used to verify the identity of parties whose signatures are notarized, and the fee charged. This journal is required by law in many states and provides a record that may be used as evidence in court.

For example, if a notary public notarizes a document, they will record the details of the transaction in their notarial register. This includes the date and time of the notarization, the type of document notarized, the name of the person who signed the document, and the fee charged for the notarization.

Another example is if a notary public verifies the identity of a person signing a document, they will record the details of the transaction in their notarial register. This includes the date and time of the verification, the type of identification used to verify the person's identity, the name of the person whose identity was verified, and the fee charged for the verification.

These examples illustrate how a notarial register is used to keep a record of notarial transactions and provide evidence of those transactions if needed in court.
