Tennessee Code Title 9. Public Finances § 9-21-123

(a) Subject to subsection (b), any local government may, by resolution duly adopted by its governing body, authorize and direct the paying agent for its bonds, notes and coupons, or other person in possession of its bonds, notes and coupons, to destroy all bonds, notes and coupons duly paid and cancelled.

(b) Such bonds, notes and coupons duly paid and cancelled during any fiscal year may be destroyed only after the fiscal audit of the local government covering the fiscal year has been completed and the appropriate local government official shall have properly posted all bonds, notes and coupons duly paid and cancelled to the local government bond, note and coupon records on a current basis. If the audit reflects that all bonds, notes and coupons duly paid and cancelled have been properly accounted for, then the paying agents or other persons who have the local government's bonds, notes and coupons in their possession shall, at the direction of the local government, destroy the same and furnish a certified list of bonds, notes and coupons duly paid and cancelled by issue showing the bond, note and coupon number, the amount of each, the date paid and such additional information as the governing body may require. The governing body shall cause the certified list of bonds, notes and coupons duly paid and cancelled to be recorded in the official minutes of the governing body.
