La. Child. Code art. 1307.10

A. Except as otherwise provided in Paragraphs C and D of this Article, a tribunal of this state shall recognize and enforce a foreign support agreement registered in this state.

B. An application or direct request for recognition and enforcement of a foreign support agreement must be accompanied by:

(1) A complete text of the foreign support agreement; and

(2) A record stating that the foreign support agreement is enforceable as an order of support in the issuing country.

C. A tribunal of this state may vacate the registration of a foreign support agreement only if, acting on its own motion, the tribunal finds that recognition and enforcement would be manifestly incompatible with public policy.

D. In a contest of a foreign support agreement, a tribunal of this state may refuse recognition and enforcement of the agreement if it finds:

(1) Recognition and enforcement of the agreement is manifestly incompatible with public policy;

(2) The agreement was obtained by fraud or falsification;

(3) The agreement is incompatible with a support order involving the same parties and having the same purpose in this state, another state, or a foreign country if the support order is entitled to recognition and enforcement under this Chapter in this state; or

(4) The record submitted under Paragraph B of this Article lacks authenticity or integrity.

E. A proceeding for recognition and enforcement of a foreign support agreement shall be suspended during the pendency of a challenge to or appeal of the agreement before a tribunal of another state or a foreign country.
