Massachusetts General Laws Part II. Real and Personal Property and Domestic Relations (Ch. 183-210) Ch. 209D, § 5-507

Administrative enforcement of orders. (a) A party or support enforcement agency seeking to enforce a support order or an income-withholding order, or both, issued in another state or a foreign support order may send the documents required for registering the order to a support enforcement agency of the commonwealth.

(b) Upon receipt of the documents, the support enforcement agency, without initially seeking to register the order, shall consider and, if appropriate, use any administrative procedure authorized by the law of the commonwealth to enforce a support order or an income-withholding order or both. If the obligor does not contest administrative enforcement, the order need not be registered. If the obligor contests the validity or administrative enforcement of the order, the support enforcement agency shall register the order pursuant to this chapter.
