Tennessee Code Title 9. Public Finances § 9-19-106

(a) Notwithstanding any other law to the contrary, public obligations issued in registered form are not required to bear manual signatures of officials of the issuer if such public obligations bear facsimile signatures in lieu thereof, and are certified or authenticated with the manual signature of an officer of the registration agent, and if the use of such facsimile signatures and certification or authentication is provided for in the official actions of the official body authorizing such obligations.

(b) In case any official of the issuer whose signature or facsimile signature appears on a public obligation shall cease to hold office before the delivery thereof to the initial purchasers or before any exchange or transfer between subsequent holders thereof, such signature or facsimile signature nevertheless shall be valid for all purposes the same as if such official had remained in office until after such delivery, exchange or transfer.

(c) When a seal is required or permitted in the execution of any public obligation, the seal may be printed, engraved, stamped, or otherwise placed in facsimile thereon. The facsimile seal has the same legal effect as the impression of the seal.

(d) Notwithstanding the foregoing, no signature or endorsement shall be required upon the original issuance or subsequent transfer of fully registered public obligations in the event that such obligations are issued in book-entry form.
