Tenn. Code Ann. § 43-38-704: Expenses

(a) On termination of the proceeding the court may require the plaintiff to pay the defendant's reasonable expenses, including counsel fees, incurred in defending the proceeding, if it finds that the proceeding was commenced without reasonable cause.

(b) If a derivative action is successful in whole or in part, or if anything is received by the plaintiff as a result of a judgment, compromise or settlement of any such action, the court may award the plaintiff reasonable expenses, including reasonable counsel fees. If anything is so received by the plaintiff, the court shall make the award of the plaintiff's expenses payable out of those proceeds and direct the plaintiff to remit to the cooperative the remainder thereof, and if those proceeds are insufficient to reimburse the plaintiff's reasonable expenses, the court may direct that the award of the plaintiff's expenses or portion thereof be paid by the cooperative.
