I have a question concerning a house that was in my grandmothers and fathers names. She has passed and now the only name on the house is my fathers. We did not know it at the time but she ran up a quite considerable credit card debt. He creditors are now telling my father that they are going to put a lien on the house. What does this mean? I thought that if the house was my fathers, they would have no right to it. I would appreciate it if you could help me out a little on this one. Thank you
