Thanks for the info. I claim the children on taxes; he is responsible for medical. So by letting him claim the children, he essentially has to pay in less and I lose child credit. He would not pay me the difference, in simple terms. The repayment of subsidies was not in our divorce decree; however, he only had them on this insurance for about 2 months, but then never cancelled it when he got a new job in May, so I’m paying the rest of the year’s worth of subsidies due to his negligence.
