My wife recently filed Ch. 13 Bankruptcy (B/K). We are separated, but not divorced. She and I have filed 3 B/Ks apiece (Ch. 7 & 11) in the past. One a piece was dismissed because we saw we could get debt relief in other ways. Her main debt in this current b/k is the house mortgage. We owned 2 other residential properties, both lost in foreclosure, BUT this was our primary residence. Recently the lender filed a 'Motion For Relief From Automatic Stay'. The Motion has not been heard yet. However, yesterday I learned the lender SOLD the debt to another Mortgage Company. Is this legal in Bankruptcy proceedings? Further, can they take our primary homestead in this Ch. 13 B/K or is it exempt?
