Tennessee Code Title 35. Fiduciaries and Trust Estates § 35-13-110

(a) In all court actions directly affecting the amount, administration or disposition of a charitable gift or a discretionary charitable gift, the court may require that the attorney general and reporter be made a party to represent the charitable beneficiaries, potential charitable beneficiaries and all citizens of the state in all legal matters pertaining to the amount, administration and disposition of a charitable gift or discretionary charitable gift. The attorney general and reporter may sue and be sued, and, insofar as the suit against the attorney general and reporter is against the state, the state expressly consents to be sued. The attorney general and reporter may designate a district attorney general to prosecute or defend any court action.

(b) It is unlawful to settle any litigation concerning the validity of a charitable gift or discretionary charitable gift without first obtaining the approval of the court. The court shall approve a settlement only after determining that the interest of the people of the state, as true beneficiaries of any charitable gift, has been served.
