Tennessee Code Title 9. Public Finances § 9-21-111

(a) Bonds and notes issued under this chapter in registered form shall be executed in the manner provided for in the Tennessee Public Obligations Registration Act, compiled in chapter 19 of this title.

(b) Bonds, notes, and any interest coupons attached thereto issued under this chapter which are not in registered form may, if so authorized by the governing body of the local government, bear or be executed with the facsimile signature of the chief executive officer of the local government; provided, that each bond, or note, shall be manually signed by the county clerk, by the city recorder or other similar local government official so authorized by resolution of the governing body of the local government.

(c) When an official or corporate seal of the local government, its governing body or of any local government official is required or permitted in the execution of any bond, note or coupon, 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) In case any official whose signature or facsimile signature appears on the bonds, notes or coupons shall cease to be such official before the delivery of the bonds, notes, or coupons to the purchaser, that signature shall be valid and sufficient for all purposes, as if that official had remained in office until the delivery of the bonds, notes or coupons.
