I'd let the court sort it out. The court is capable of apportioning the debts/assets in an equitable way. Just emphasize that you cannot trust him to make the payments (and you've got the mediator and your lawyer who heard what he said about that). If the court awards you the asset he gets nothing when it's sold. As for credit card debt, if the card is in both names, the credit card company can come after you for anything he doesn't pay anyway. You have a contract with them that gives them the right to do that. All the more reason for you to ask the court to give you the assets.
