My spouse is years behind in both alimony and child support thanks to COVID he is actually catching up since he gets unemployment and other pluses. He still owes $20,000 I was divorced in 2010. My question is since this amount is arrears and significant compared to the $17.00 a month I was getting it hurts my overall income instead of helping with the tax I owe on it. Do I have to pay on the arrears or only on the amount he actually owes for the year?
