Tennessee Code Title 29. Remedies and Special Proceedings § 29-27-208

(b)(1) If such person is incapable of giving assent, the court may determine, under all the circumstances, and taking into view the interest of all the parties, whether such estate ought to be excepted from the sale, or sold.

(2) If the person entitled to any such estate for life be unknown, the court may determine whether the estate shall be sold or not, as in the case of persons under disability, and, in the event of sale, make such order for the protection of the rights of such person in the same manner, as far as may be, as if the person were known and had appeared.
