No worries, you won’t lose your son. I know this is their personal matter, but if they have already done with discussion of divorce, then the husband should discuss the property or home selling topic to his wife as they haven’t yet got apart from each other legally. According to me, the lady should hire a lawyer or estate planning attorney ( http://www.scottcounsel.com/NJEstatePlanningAttorney/ ) to take some steps on her behalf and in her favor. This will help the lady to take some decisions in her favor.
