Effect of registration for enforcement.

A support order or income-withholding order issued in another state or a foreign support order is registered when the order is filed in the registering tribunal of the District. A registered support order issued in another state or a foreign country is enforceable in the same manner and is subject to the same procedures as an order issued by a tribunal of the District. Except as otherwise provided in this chapter, a tribunal of the District shall recognize and enforce, but may not modify, a registered support order if the issuing tribunal had jurisdiction.
