My father died in November 2006. He is survived by my mother, my sister and me. However I was advised to include my grandmother also as his legal heir. So, alongwith me, my mother and my sister, my grandmother is also a legal heir of my father. Naturally, on all of my father's real estate propertries, i.e. plots, a farm and a house, my grandmother is also one of the owners (alongwith my sister, mother and myself). I want to know whether after my grandmother's death, would my uncles' name will be added to those real estate properties that were originally owned by my late father, and now jointly by me, my sister, mother and grandmother? Naturally my uncles will be the legal heirs of my grandmother after her death. If their names will actually be added, please advise me what should I do to avoid that. All my uncles are well-to-do and have no interest in my late father's real estate properties. Should I make my grandmother to prepare a will that will forbid any claim by my uncles on my late father's properties? Will it be legally binding on my uncles? If yes, what's the procedure for it? Please guide me, advocates.
