Mortgage interest deductions

Can I deduct interest payments I have been making on a Mortgage that is in my deceased Fathers name.  The Estate is still open due to the fact that we still need to sell some other property my Father owned so I am unable to write the a mortgage in my name.  The houses deed is in my name now, but the mortgage is still in my Fathers name.  I live in the property and it is my main docile.
