Article 2 - Jurisdiction
§ 93-25-205. Continuing, exclusive jurisdiction

A tribunal of this state that has issued a child-support order consistent with the law of this state has and shall exercise continuing, exclusive jurisdiction to modify its child-support order if the order is the controlling order and:
A tribunal of this state that has issued a child-support order consistent with the law of this state may not exercise continuing exclusive jurisdiction to modify the order if:
All of the parties who are individuals file consent in a record with the tribunal of this state that a tribunal of another state that has jurisdiction over at least one (1) of the parties who is an individual or that is located in the state of residence of the child may modify the order and assume continuing, exclusive jurisdiction; or
Its order is not the controlling order.
If a tribunal of another state has issued a child-support order pursuant to the Uniform Interstate Family Support Act or to a law substantially similar to this chapter which modifies a child-support order of a tribunal of this state, tribunals of this state shall recognize the continuing, exclusive jurisdiction of the tribunal of the other state.
A tribunal of this state that lacks continuing, exclusive jurisdiction to modify a child-support order may serve as an initiating tribunal to request a tribunal of another state to modify a support order issued in that state.
A temporary support order issued ex parte or pending resolution of a jurisdictional conflict does not create continuing, exclusive jurisdiction in the issuing tribunal.
