How much does a notary public cost?

The cost of a notary's services varies from state to state. In most states a notary charges $5 to $10 per notarial act or signature, depending on the document and the service provided. Each state sets maximum fee amounts to prevent notaries from overcharging.

If a notary charges more than the state maximum, he can be fined or lose his license for notary misconduct. Mobile notaries can charge clients for mileage. There are state maximums for that fee as well. Photocopying, ink and journals costs can be charged to a client if a large number of services are required. Notaries should communicate fees to potential clients before services are rendered.
