Tenn. Code Ann. § 30-2-409: Proceeding by scire facias when debt sued on prior to deceased's death

(a) Where no person will administer on the estate of the deceased, any person who has commenced a suit against the deceased in the lifetime of the deceased may issue a scire facias against the deceased's heirs or devisees, for whom, in case they are minors, the court shall appoint a guardian ad litem for the purpose of defending the suit.

(b) On return of the scire facias made known to the guardian and heirs, or devisees, the plaintiff may prosecute the suit to judgment and execution against the real estate of the ancestor descended or devised to the heirs or devisees.
