I'm not Lee, but here's what the IRS says about it.Qualified domestic relations order (QDRO). You may be able to roll over tax free all or part of a distribution you receive from the CSRS, the FERS, or the TSP under a court order in a divorce or similar proceeding. You must receive the distribution as the government employee's spouse or former spouse (not as a nonspousal beneficiary). The rollover rules apply to you as if you were the employee. You can roll over the distribution if it is an eligible rollover distribution (described earlier) and it is made under a QDRO or, for the TSP, a qualifying order.
A QDRO is a judgment, decree, or order relating to payment of child support, alimony, or marital property rights. The payments must be made to a spouse, former spouse, child, or other dependent of a participant in the plan. For the TSP, a QDRO can be a qualifying order, but a domestic relations order can be a qualifying order even if it is not a QDRO. For example, a qualifying order can include an order that requires a TSP payment of attorney's fees to the attorney for the spouse, former spouse, or child of the participant.
The order must contain certain information, including the amount or percentage of the participant's benefits to be paid to each payee. It cannot require the plan to pay benefits in a form not offered by the plan, nor can it require the plan to pay increased benefits.
A distribution that is paid to a child, dependent, or, if applicable, an attorney for fees, under a QDRO or a qualifying order is taxed to the plan participant.
