If the order is determined to be a QDRO, TRS shall, subject to the limitations of this chapter, pay benefits in accordance with the order at the time of distribution of benefits or withdrawn contributions to a member or prior to a distribution to the member as provided in §47.17 of this title (relating to Calculation for Alternate Payee Benefits Before a Member's Benefit Begins). Any determination that an order is a QDRO is voidable or subject to modification if TRS determines that the provisions of the order have been changed or that circumstances relevant to the determination have changed.
