No. you cannot attach anything to it. The property will be probably seized and either short saled, chapter 13'd or let go completely. If he holds the mortgage then you are not his creditor, and the bank is. You have to seek separate proceedings, if he does a chapter 13, chances are you are not going to get much child support. If you file for support, it is considered secured debt and MUST be paid along with all other secured debts first, so you are better off. Otherwise you have to hit his wallet and leave the house alone. A lien will only serve as freezing assets on an already lost cause. You won't get anything from a short sale or forclosure settlement. Start shopping for lawyers.
