Can filing bankruptcy stop a foreclosure/auction on your house.

Yes.  The Automatic Stay in bankruptcy stops any and all collections actions on any debt.  How long it stops for depends on which chapter you file and what you propose to do in the bankruptcy case. Typically a Chapter 13 case is used to catch up on mortgage arrears over time, while staying current with ongoing mortgage payments that come due after the case is filed. Mark J.
