My ex-husband called yesterday pretty irate saying he was going to claim my kids on his tax returns this year. Per court papers he has the right to claim them every other year, but I dont see it fair. I claimed them again this year and he's threathning me with an IRS Audit. I thought he had to be current with his child support in order to be allowed to claim them. He is 11,000+ in arrears. He has no relationship with my kids now almost 15 and 18. No communication in the last 2 yrs. I pay the medical, dental, school expenses, I provide food, clothing and everything a 14 and 17 yr old need. He does pay child support, but hardly ever the amount he's supposed to. In the lst year he even missed paying anything 4 months out of the year. If I have sole custody and 90% resposible for them shouldnt I be allowed to claim them despite what the order says? Or should I worry that I will have to pay the IRS back?
