So sorry to hear of your problem. Now, since I am not an attny, I cannot give legal advice, but I will share some info that you can also research online.
There have been many scams lately in which homeowners are fooled into signing over their properties in an effort to prevent foreclosure; sometimes these properties are placed in a "trust" where investors supposedly pay what's delinquent, allowing owners to get back on their feet and re-finance at a later date. Homeowners don't always know that they have signed over their deeds and may get foreclosed by a variety of different methods. I'm not sure if this is what happened to you, and perhaps legal counsel is the best way to find out for sure.
With that said, and depending on what you want to do, an attny consultation might be appropriate.
I wish you luck with this and again, so sorry to hear about your troubles.
