It appears that the interest which you own in the house (the car too, apparently) is essentially the right to receive money when the property is sold. These interests are not, as far as you are concerned, exempt (other than possibly under the blanket bankruptcy code exmption). But that doesn't matter; as I understand what you are saying, they don't have to be sold by any time certain. So, if that is what your divorce decree provides, you don't have to be concerned that they are "in danger" because of your bankruptcy. If you have in fact signed them over to him, the bankruptcy trustee can not take and sell them because you don't have the right to sell them and get the proceeds.
On the other hand, the property will be sold someday (when he dies, or whenever). At that time, you, or your heirs, would be entiltled to 30%. This expectancy, whatever it is worth, can be sold, and the proceeds would go to the trustee in behalf of the unsecured creditors.
