Ex spouse claimed child without consent form
I have sole custody so the children live with me 100% of the time. I did not fill out the 8332 form. Went to file taxes and kids were claimed. We have a court order stating he can claim them if not in arrears but it’s showing arrears on the state child support enforcement website. How long would it take for the IRS to remedy? Also, having sole custody, and the court case was after 2009, I have to fill out the 8332, i didn’t so since he knew that and filed anyway, would he lose in this situation?
