There are a couple of things that you can do. You can file a probate petition to be appointed as special administrator for your father's estate so that you can deal directly with the mortgage lender. Second, you can file for a temporary restraining order and preliminary injunction to postpone the sale until the court determines that the mortgage lender complied with California law regarding the foreclosure. Bottom line: you need an attorney.
