In addition to any other credit or offset available to an obligor under this title, if a child for whom the obligor owes child support receives a lump-sum payment as a result of the obligor's disability and that payment is made to the obligee as the representative payee of the child, the obligor is entitled to a credit. The credit under this section is equal to the amount of the lump-sum payment and shall be applied only to any child support arrearage and interest owed by the obligor on behalf of that child at the time the payment is made. The credit under this section may not be used to reduce the amount of a periodic child support obligation ordered under Chapter 154 that has not yet accrued.
