(a) A tribunal in Georgia issuing a support order consistent with the law of Georgia has continuing, exclusive jurisdiction over a child support order:

(1) As long as Georgia remains the residence of the obligor, the individual obligee, or the child for whose benefit the support order is issued; or

(2) Until all of the parties who are individuals have filed written consents with the tribunal in Georgia for a tribunal of another state to modify the order and assume continuing, exclusive jurisdiction.

(b) A tribunal in Georgia issuing a child support order consistent with the law of Georgia may not exercise its continuing jurisdiction to modify the order if the order has been modified by a tribunal of another state pursuant to this article or a law substantially similar to this article.

(c) If a child support order of Georgia is modified by a tribunal of another state pursuant to this article or a law substantially similar to this article, a tribunal in Georgia loses its continuing, exclusive jurisdiction with regard to prospective enforcement of the order issued in Georgia and may only:

(1) Enforce the order that was modified as to amounts accruing before the modification;

(2) Enforce nonmodifiable aspects of that order; and

(3) Provide other appropriate relief for violations of that order which occurred before the effective date of the modification.

(d) A tribunal of Georgia shall recognize the continuing, exclusive jurisdiction of a tribunal of another state which has issued a child support order pursuant to this article or a law substantially similar to this article.

(e) A temporary support order issued ex parte or pending resolution of a jurisdictional conflict does not create continuing, exclusive jurisdiction in the issuing tribunal.

(f) A tribunal of Georgia issuing a support order consistent with the law of Georgia has continuing, exclusive jurisdiction over a spousal support order throughout the existence of the support obligation. A tribunal of Georgia may not modify a spousal support order issued by a tribunal of another state having continuing, exclusive jurisdiction over that order under the law of that state.
