My ex has locked me out of our marital home that was given to me per my divorce papers

I divorced and the papers say I get the house until it forcloses or my ex short sells the house but he kicked me out and is now trying to move in with his new wife. I filed for banckrupcy and put the house on it as we were letting it foreclose but it seems that they may be paying off loans and trying to get the house caught up. The house is in a trust in the name of my ex and I. The papers specifically say I shall have exclusive possession of the parties marital residence until such time that the house is foreclosed or sold. I don't want to sell it to him because it has equity and he will never give that to me as he's in the rears on his support as well as owes me for legal fees that the court awarded me. I have no money for legal assistance so feel I may get the worst end of this. I have three minor children with my ex.
