Cost to notarize documents is a fee associated with verifying the authenticity of important legal documents, such as trusts and wills. This cost covers the time, travel expenses, and other associated costs of having a Notary Public come to your location or place of business and officially “notarize” your document. The cost of notarizing will vary depending on several factors, such as the number of documents being notarized and the distance the Notary needs to travel. However, it’s usually quite affordable for an individual document. As a business, you may want to discuss contractual arrangements with a Notary to minimize your costs.
