Tennessee Code Title 66. Property § 66-1-206

(a) Except as provided in subsection (b), this part applies to nonvested property interests and unexercised powers of appointment regardless of whether they were created before, on, or after July 1, 1994. A property interest shall not be deemed vested merely because it would vest if the common law rule against perpetuities were violated.

(b) This part does not apply to any property interest or power of appointment the validity of which has been determined by a final judgment in a judicial proceeding or by a settlement among interested persons prior to July 1, 1994.
