Tennessee Code Title 50. Employer and Employee § 50-5-209

(a) Approval under this part may be sought for a contract or agreement that is fully executed, is already in existence or under which the parties are currently performing. Approval may be effective as of the date upon which the contract has been executed, or the date when services were first performed by the minor, if specifically so ordered by the court. The parties may petition the court for approval to be effective within one (1) year of the contract's ratification by the court. The parties may also petition the court for approval of a contract effective date more than one (1) year after the ratification of the contract by the court, if good cause for the delayed effective date is shown by the petitioners.

(b) If a contract is approved pursuant to this part, all earnings, royalties, or other compensation earned or received by the minor pursuant to the approved contract shall become the sole property of the minor who will be authorized to execute any contracts relating to administration or investments of the earnings.
