Tennessee Code Title 8. Public Officers and Employees § 8-16-112

(a) A Tennessee notary public is authorized to act in any county in the state and has the power to acknowledge signatures upon personal knowledge or satisfactory proof, to administer oaths, to take depositions, to qualify parties to bills in chancery, and to take affidavits, in all cases. Furthermore, in all such cases the notary public's seal shall be affixed and the notary public shall sign such documents in ink by the notary's own hand unless otherwise provided by law.

(b) The requirement of a notary public's signature in ink or by the notary's hand and a seal is satisfied if an electronic signature or a digitized image of a wet signature of the person authorized to perform that act, and all other information required to be included, is attached to or logically associated with the document or signature. A physical or electronic image of a stamp, impression, or seal need not accompany an electronic signature.
