A member may change or update his or her beneficiary designation for the statutory death benefit at any time in the manner prescribed by TRS. A beneficiary designation is valid for TRS purposes when properly executed and on file with TRS prior to the death of the member. TRS shall not be responsible for determining the competency of a member to designate a beneficiary except as otherwise provided by Oklahoma law.
