Tenn. Code Ann. § 56-26-117

The insured shall not be bound by any statement made in an application for a policy unless a copy of such application is attached to or endorsed on the policy when issued as part of the policy. If any such policy delivered or issued for delivery to any person in this state is reinstated or renewed, and the insured or the beneficiary or assignee of the policy makes written request to the insurer for a copy of the application, if any, for the reinstatement or renewal, the insurer shall within fifteen (15) days after the receipt of the request at its home office or any branch office of the insurer, deliver or mail to the person making the request a copy of the application. If the copy is not so delivered or mailed, the insurer shall be precluded from introducing the application as evidence in any action or proceeding based upon or involving the policy or its reinstatement or renewal.
