If you filed chapter 7 and included the house in the bankruptcy you don't owe the debt but are still on the deed, the bank would have right to that deed and could obtain it through foreclosure, you could also by deed in lieu of foreclosure sign it over to them. They may also allow you to short sale it. All of this as Laura stated should be discussed with your attorney.
Was your home excluded from the bankruptcy? If you are living there and current on your payments why would you want to get off the deed? You need to go into more detail on this with your bankruptcy attorney.
