34 Tex. Admin. Code § 47.15
The death of an alternate payee shall terminate the interest of that payee in TRS. Upon proof of death of the alternate payee, the member, retiree, or beneficiary shall be entitled to receive the full amount of payments payable in the future to the member, retiree, or beneficiary without reduction for the amount previously being paid to the alternate payee under the QDRO. However, when an alternate payee is receiving benefits under §804.005, in lieu of benefits awarded in the QDRO, there is no reversion of the alternate payee's benefit to the member upon the alternate payee's death, regardless of whether the death occurs before or after the member's benefit commencement. This section does not affect the manner of payment of benefits to the member, retiree, or beneficiary.
