Eddie and I, and others, have explained it many times, Tiger. You are divorced, which means that you no longer have any claim on the house, which does not belong to you or your ex-husband, so you have to leave it.
I would think that your ex-in-laws will have sought their own legal advice before issuing you with the eviction order, so they know that right is on their side.
It says in that paragraph that your interest in the property ceased on the day you divorced.
Financial settlements are nothing to do with this, financial means cash, not the house. It can't be clearer than that.
