Tenn. Code Ann. § 8-19-302: Obligation on defective bond

Whenever any officer, required by law to give an official bond, acts under a bond which is not in the penalty, payable, or conditioned as prescribed by law, or is otherwise defective, such bond is not void, but stands in the place of the official bond, subject, on its condition being broken, to all the remedies which the person aggrieved might have maintained on the official bond of such officer, executed, approved, and filed according to law.
