My ex and I were never married and after our daughter was born we only lived with him for about 5weeks at the end of the year. I did not make enough money to claim our daughter but I told him if i agreed to let him claim her it was to go into an account an what he got back for her was to be used to pay off the debt he put me in,give our daughter the money he took from her babyshower and the rest be split evenly and he agreed. i never gave him permission or signed the papers saying he could claim her and all of a sudden he tells me he claimed her and only paying my debt and saying he has every right to claim her because we lived with him and says I'm not custodial parent even though we were never married.. I called a few tax services and they said its illegal so if i take him to court will he have to pay the money back to the irs or give it to me? I really needed the money to buy her a crib because he won't let me have the one we had living with him because his mom bought it. Though he hasn't seen our daughter in over a month and due to domestic violence she will not be at his house. hope i can get some advice thank you in advance.I am in Ohio.
