Tennessee Code Title 50. Employer and Employee § 50-6-229

(a) The amounts of compensation payable periodically under this chapter may be commuted to one (1) or more lump sum payments.

No agreed stipulation or order or any agreement by the employer and employee or any other party to the proceeding shall be a prerequisite to the court's approval or disapproval of the award being paid in one (1) or more lump sum payments. In making the commutation, the lump sum payment shall, in the aggregate, amount to a sum of all future installments of compensation. No settlement or compromise shall be made except on the terms provided in this chapter.
