Tennessee Code Title 34. Guardianship § 34-1-132

(a) If the court finds that compliance with the procedures of this title will likely result in substantial harm to the respondent's health, safety, or welfare, and that no other person, including an agent acting under the Health Care Decision Act, compiled in title 68, chapter 11, part 18, or a person acting under the Durable Powers of Attorney for Healthcare Act, compiled in chapter 6, part 2 of this title or a living will pursuant to title 32, chapter 11, appears to have authority to act, willingness to act, and is acting in the best interests of the respondent in the circumstances, then the court, on petition by a person interested in the respondent's welfare, may appoint an emergency guardian or conservator whose authority may not exceed sixty (60) days and who may exercise only the powers specified in the order. Immediately upon receipt of the petition for an emergency guardianship or conservatorship, the court shall appoint an attorney ad litem to represent the respondent in the proceeding. Except as otherwise provided in subsection (b), reasonable notice of the time and place of a hearing on the petition shall be given to the respondent and any other person as the court directs.

(b) An emergency guardian or conservator may be appointed without notice to the respondent and the attorney ad litem only if the court finds upon a sworn petition that the respondent will be substantially harmed before a hearing on the appointment can be held. If the court appoints an emergency guardian or conservator without notice to the respondent, the respondent shall be given notice of the appointment within forty-eight (48) hours after the appointment. The court shall hold a hearing on the appropriateness of the appointment within five (5) days after the appointment.

(c) Appointment of an emergency guardian or conservator, with or without notice, is not a determination of the respondent's incapacity.

(d) The court may remove an emergency guardian or conservator at any time. The court may appoint a guardian ad litem to investigate the circumstances. An emergency guardian or conservator shall make any report the court requires. In other respects, the provisions of this title concerning guardians or conservators apply to an emergency guardian or conservator.

(e) The time periods set forth above in this section are mandatory and not directory. Failure to comply with those provisions shall void any emergency appointment and remove the authority previously granted to an emergency fiduciary.
