Ok. Thanks. I thought that's what you meant, but wanted to be sure.
If your ex is in bankruptcy, his bankruptcy attorney can file a petition to set aside the judgment and have it discharged through his bankruptcy - - which will remove the judgment lien. Once that is done, the bankruptcy judge can also allow your ex to transfer his interest to you per the court's order. If his attorney will not do this, you can file a petition in his bankruptcy for an order removing the lien from your property.
But, you're going to have to go through the bankruptcy court and get the lien cleared before you can get the property transferred from him to you, so you could then sell the property.
You could also file a petition in family court
to hold him in contempt of court for failing to transfer title - - but you would also have to file a motion to lift the automatic stay to allow you to pursue him on this. You can also ask the judge for your legal fees in having to take action to get this done.
Thus, this is certainly do-able, but its going to take some legal wrangling to get it done. Your best option is to consult your attorney and then allow him/her to try and work something out with your ex's bankruptcy attorney to get this done by agreement and save everyone time and money. If the attorney will not agree, then your lawyer will have to file a petition in the bankruptcy court to set aside the judgment against the property and order him to transfer the property per the court order.
