Section 2-206. Enforcement and modification of support order by tribunal having continuing jurisdiction.
(a) A tribunal of the commonwealth may serve as an initiating tribunal to request a tribunal of another state to enforce or modify a support order issued in that state.
(b) A tribunal of the commonwealth having continuing, exclusive jurisdiction over a support order may act as a responding tribunal under this chapter to enforce or modify the order. If a party subject to the continuing, exclusive jurisdiction of the tribunal no longer resides in the issuing state, in subsequent proceedings the tribunal may apply Section 3-316 (Special Rules of Evidence and Procedure) to receive evidence from another state and Section 3-318 (Assistance with Discovery) to obtain discovery through a tribunal of another state.
(c) A tribunal of the commonwealth which lacks continuing, exclusive jurisdiction over a spousal support order may not serve as a responding tribunal to modify a spousal support order of another state.
