So hubby was sent a letter saying he owed $16000 in back child support. Of course I stopped breathing. So to make a long story short, we fought it in court and won. The court declared we did not owe anything back. So I filed our taxes thinking we were safe. I was wrong. Apparently the IRS didn't get the memo and sent our return to her. The only recourse we have is to ask her for the money back and hope she gives it, or sue her. I plan wholeheartedly on taking this to court if it comes to it. I will not ask his permission, I do not care how he feels.
