My soon to be ex wife forged power of attorney and forged my signature on 2 mortgage refinances without my knowledge and credit cards.

First, you need to sign up for a credit protection service that will prevent someone from opening credit cards in your name.  You should file a police report clalming identity theft again, and indicate to the mortgage company that the documents were fraudulently obtained.  You can seek damages from her, and have the foreclosure changed to her name alone.
