| From its original promulgation UIFSA determined that the  | 
| duration of child-support obligation should be fixed by the  | 
| controlling order, see Robdau v. Commonwealth, Virginia Dept.  | 
| Social Serv., 543 S.E.2d 602 (Va. App. 2001). If the language  | 
| was insufficiently specific before the 2001, the amendments  | 
| should make this decision absolutely clear. The original time  | 
| frame for support is not modifiable unless the law of the  | 
| issuing State provides for modification of its duration. Some  | 
| courts have sought to subvert this policy by holding that  | 
| completion of the obligation to support a child through age 18  | 
| established by the now-completed controlling order does not  | 
| preclude the imposition of a new obligation thereafter to  | 
| support the child through age 21 or even to age 23 if the  | 
| child is enrolled in higher education. Subsection (d) is  | 
| designed to eliminate these attempts to create multiple,  | 
| albeit successive, support obligations. Consistent with this  | 
| principle, if a domestic violence protective order has been  | 
| entered with a child-support provision that has a duration  | 
| less than the general child support law of the State that  | 
| issues the controlling order, the law of that State determines  | 
| the maximum duration. In sum, absent tribunal error the first  | 
| child-support order issued under UIFSA will invariably be the  | 
| initial controlling order. The initial controlling order may  | 
| be modified and replaced by a new controlling order in  | 
| accordance with the terms of Sections 609-615, but the  | 
| duration of the child-support obligation remains constant,  | 
| even though virtually every other aspect of the original order  | 
| may be changed. This is also the standard in situations  | 
| involving multiple valid child-support orders--a problem that  | 
| will progressively decrease over time as RURESA multiple  | 
| orders expire or a determination of the initial controlling  | 
| order is made under Section 207, supra. Once a controlling  | 
| order is identified under these standards, the duration of the  | 
| support obligation is fixed. |
