P.R. Laws tit. 8, § 547b
(a) After a child-support order issued in another state has been registered in Puerto Rico, the responding tribunal of Puerto Rico may modify that order only if § 547e of this title does not apply and after notice and hearing it finds that:
(1) The following requirements are met:
(A) The child, the individual obligee, and the obligor do not reside in the issuing state;
(B) a petitioner who is a nonresident of this State seeks modification; and
(C) the respondent is subject to the personal jurisdiction of the tribunal of Puerto Rico; or
(2) the child, or a party who is an individual, is subject to the personal jurisdiction of the tribunal of Puerto Rico and all of the parties who are individuals have filed a written consents in the issuing tribunal for a tribunal of Puerto Rico to modify the support order and assume continuing, exclusive jurisdiction over the order. However, if the issuing state is a foreign jurisdiction that has not enacted a law or established procedures substantially similar to the procedures under this chapter, the consent otherwise required of an individual residing in Puerto Rico is not required for the tribunal to assume jurisdiction to modify the child-support order.
(b) Modification of a registered child-support order is subject to the same requirements, procedures, and defenses that apply to the modification of an order issued by a tribunal of Puerto Rico and the order may be enforced and satisfied in the same manner.
(c) A tribunal of Puerto Rico may not modify any aspect of a child-support order that may not be modified under the law of the issuing state. If two or more tribunals have issued child-support orders for the same obligor and child, the order that controls and must be so recognized under § 542f of this title establishes the aspects of the support order which are nonmodifiable.
(d) On issuance of an order modifying a child-support order issued in another state, a tribunal of Puerto Rico becomes the tribunal having continuing, exclusive jurisdiction.
