My question involves bankruptcy in the state of: LA

My mortgage was discharged in a chapter 7, but to my knowledge was supposed to be reaffirmed. Evidently, the paperwork was not completed by the Mortgage Company.

Now I am in foreclosure, and trying to work out a remodification or try the HAMP, but I don't owe them any money. Is it possible for me to stay in my house? Will the mortgage company usually work with the debtor in this situation?

Thanks
