Tennessee Code Title 47. Commercial Instruments and Transactions § 47-2-722

(a) a right of action against the third party is in either party to the contract for sale who has title to or a security interest or a special property or an insurable interest in the goods; and if the goods have been destroyed or converted a right of action is also in the party who either bore the risk of loss under the contract for sale or has since the injury assumed that risk as against the other;

(b) if at the time of the injury the party plaintiff did not bear the risk of loss as against the other party to the contract for sale and there is no arrangement between them for disposition of the recovery, his suit or settlement is, subject to his own interest, as a fiduciary for the other party to the contract;

(c) either party may with the consent of the other sue for the benefit of whom it may concern.
