Tennessee Code Title 20. Civil Procedure § 20-4-208

(a) As a further provision to prevent delay in cases of incompetency, it is the duty of the circuit court judges and chancellors, whenever there is a cause before one (1) of them, in which the circuit court judge or chancellor is interested, at the request of the opposite party, to transfer the cause to any court in an adjoining district or division that the adverse party may choose; and the original papers, with a certified copy of all orders, shall be immediately transmitted to the court to which the venue is changed.

(b) Where the judge of any court of law or chancery is incompetent, from any other cause, to try the cause, upon application of either of the parties to the suit, the suit shall be transferred to the nearest court having jurisdiction of such cases where like incompetency does not exist.
