Tenn. Code Ann. § 8-25-114

Notwithstanding any other law to the contrary, any deferred compensation program established on behalf of state employees under this part or under part 3 of this chapter shall honor claims under a qualified domestic relations order at a time designated by the state treasurer. For purposes of this section, “qualified domestic relations order” has the same meaning as provided in § 414(p) of the Internal Revenue Code of 1986 ( 26 U.S.C. § 414(p) ); provided, that such order may only relate to the provision of marital property rights for the benefit of the former spouse of the deferred compensation program participant.
