(2) The child custody determination for which enforcement is sought was registered and confirmed under R.S. 13:1827 but has been vacated, stayed, or modified by a court of a state having jurisdiction to do so under Subpart B.
B. The court shall award the fees, costs, and expenses authorized under R.S. 13:1834 and may grant additional relief, including a request for the assistance of law enforcement officials, and set a further hearing to determine whether additional relief is appropriate.
