Independent House is in the name of my mother, my father and my grand-mother (father's mother). My father also had a sister. Now, my father, my grand-mother and my father's sister all have expired. I want the house to be now transferred to my mother's name only. Can it be only done by having death certificate of my father and my grand-mother? or does my father's sister (who has also expired) come in picture. If that is the case and as she has also expired, some signature, etc from her children will be required or not?
