My mother in law has not paid her mortgage or taxes in 5 years can she still have her home?

I currently live in the home, she told me to stop paying rent because she was letting the home go into forclosure. She now wants to be paid rent but I do not believe she is in procession of the house. Several papers have came to the house from the bank and other attorneys. Do I have to pay her rent? What should I do to find out if the house is back bank owned?
