In a divorce, when Spouse A leaves the marital homestead in the hands of Spouse B, typically Spouse B must buy out the marital interest of Spouse A. At least, that is how things used to be, before the current era of the depressed housing market. Today, it is not unusual for Spouse A to leave the house behind,and not to be bought out by Spouse B at all. The departing spouse is likely to be only too happy to leave the mortgage payment behind as well, and to get out from underneath the burden of a big house payment and shrinking home equity.
