What follows the signature of the notary public in a certificate?

Following the signature of the notary public in a certificate, the notary's commission expiry date is typically included. This inclusion ensures that any individual reviewing the document can verify that the notary's commission was valid at the time the notarization occurred. By providing this information, it helps assure the parties involved that the notary was authorized to perform the notarization, as a notary's commission is not indefinite and must be renewed at certain intervals.

In contrast, while contact information of the notary, the date of notarization, and the type of document being notarized may also be relevant, they do not specifically follow the notary's signature in the certificate format mandated by Illinois law. The date of notarization is usually noted within the certificate, but it does not follow immediately after the signature. The type of document and contact information, although useful, are generally not required components immediately after the signature in a notarial certificate.
