Tennessee Code Title 33. Mental Health and Substance Abuse and Intellectual and Developmental Disabilities § 33-6-618

(1) The burden of proof to establish, as appropriate to the proceedings, that the outpatient treatment plan is proper, that the person is subject to return to the hospital, or that the plan is subject to extension, shall be by clear, unequivocal, and convincing evidence and shall be borne by the party seeking to impose the obligations;

(2) The person shall be present at the hearing unless the person waives such presence in writing. If the person's attorney shows that the person's physical health would be endangered by being at the hearing, the court may order a continuance until the risk is terminated. If the court determines that the person's conduct at the hearing is so violent or otherwise disruptive that it creates a serious risk of harm to the person or others at the hearing or so disrupts the proceedings that they cannot be conducted in a proper manner, the court may order the person restrained or excluded to the extent necessary to the proper conduct of the proceedings. If the person is not present at or is excluded from the hearing, the court shall make a written fact finding as to why the hearing is held in the person's absence; and

(3) The person's attorney shall notify the court of the representation immediately after accepting it. If the person does not employ an attorney, the court shall appoint an attorney to represent the person as soon as possible after the case is docketed. An attorney representing the person shall not serve as guardian ad litem. If the court determines that the person is not able to understand the nature of the proceedings and cannot communicate with counsel in the conduct of the case, the court may appoint another person to serve as the person's guardian ad litem.
