P.R. Laws tit. 8, § 542f
(a) If a proceeding is brought under this chapter and only one tribunal has issued a child-support order, the order of that tribunal controls and must be so recognized.
(b) If a proceeding is brought under this chapter, and two or more child-support orders have been issued by tribunals of Puerto Rico or another state with regard to the same obligor and child, a tribunal of Puerto Rico shall apply the following rules in determining which order to recognize for purposes of continuing, exclusive jurisdiction:
(1) If only one of the tribunals would have continuing, exclusive jurisdiction under this chapter, the order of that tribunal controls and must be so recognized.
(2) If more than one of the tribunals would have continuing, exclusive jurisdiction under this chapter, an order issued by a tribunal in the current home state of the child controls and must be so recognized, but if an order has not been issued in the current home state of the child, the order most recently issued controls and must be so recognized.
(3) If none of the tribunals would have continuing, exclusive jurisdiction under this chapter, the tribunal of Puerto Rico having jurisdiction over the parties shall issue a child-support order, which controls and must be so recognized.
(c) If two or more child-support orders have been issued for the same obligor and child and if the obligor or the individual obligee resides in Puerto Rico, a party may request a tribunal of Puerto Rico to determine which order controls and must be so recognized under subsection (b) of this section. The request must be accompanied by a certified copy of every support order in effect. The requesting party shall give notice of the request to each party whose rights may be affected by the determination.
(d) The tribunal that issued the controlling order under subsections (a), (b), or (c) of this section is the tribunal that has continuing, exclusive jurisdiction under § 542d of this title.
(e) A tribunal of Puerto Rico which determines by order the identity of the controlling order under subsection (b)(1) or (2) of this section or which issues a new controlling order under subsection (b)(3) of this section shall state in that order the basis upon which the tribunal made its determination.
(f) Within thirty (30) days after issuance of an order determining the identity of the controlling order, the party obtaining the order shall file a certified copy of it with each tribunal that issued or registered an earlier order of child support. A party who obtains the order and fails to file a certified copy is subject to appropriate sanctions by a tribunal in which the issue of failure to file arises. The failure to file does not affect the validity or enforceability of the controlling order.
