Money given to CFI but case was dismissed due to lack of jurisdiction...?

Children and I live in different state than where husband filed for divorce. Husband's state tried to claim jurisdiction over custody proceedings despite the fact our state is the habitual residence and home state. CFI was appointed in husband's state and investigation began. During this time I argued lack of jurisdiction (argued for 7 months). Custody proceeding was recently dismissed and husband's state admitted to not having jurisdiction and that our state does. Before dismissal, both parties were ordered to pay CFI $2k, I refused based on my arguement of jurisdiction. Husband paid. Now it has been dismissed he claims they refuse to refund the money. I feel had the state followed their own laws from the beginning, the CFI wouldn't have been involved and no money would have been exchanged. It is the county's error, not me or my husband's. He also claims the CFI told him I owe several thousand as well. Who is right?
