My grandfather passed away about 6 years ago. And my grandmother just passed away in July of 2008. I'm trying to find out how I would go about changing the deed of their house over to me. Neither one of them had a will... and they never changed the names on the deed over to me. My mother and my aunt do not want the house and they have told me that I could keep living here and have the house. Are they able to sign the deed over to me? My mother is the oldest and then my aunt after that I'm next. Can someone please help me? Also if they can what is needed in that process? Thanks.

Did you say what state? You must go through the probate court. Check this: Probate - Wikipedia, the free encyclopedia

I live in Pa. sorry for leaving that out. And thank you for your answer.
