The notary public invoice is for any services that have been performed on behalf of an individual or business by a notarial officer. It is a notary’s job to ensure that all signatures are valid on a legal document and that no one is signing against their will. A small fee will be charged for their services, often on a “per-signature” basis. The invoice template can be used to describe the act provided by the notary (acknowledgment, jurats, etc.) and the cost of notarizing each signature. The total amount of the transaction will be detailed at the bottom of the document.
