My question involves a foreclosure in the State of: California

My question is this: if my house has gone into foreclosure (i received the Notice of Trustee Sale in Oct '10), but has apparently not sold at auction, thus I have not received any tax forms related to the property - what is my 2010 tax filing obligation? Also, hasn't the property been "transferred" to the bank once you receive the Notice of Trustee Sale - why does this not trigger a tax form? ANY info will be appreciated....
