A notary fee is a charge for the services of a notary public. This fee covers the costs associated with witnessing and authenticating documents, such as property deeds, contracts and other official documents. Notaries have both historical and contemporary importance to business and finance, as they serve to help protect both parties in a contract from fraud. As such, they are extremely important in ensuring that any legal documents are valid and enforceable. The notary fee can vary depending on where you live, but typically it ranges from $5-$50, depending on the level of service provided.
