Can I claim share in grandfathers property after fathers death

Dear Sir, My Grandfather had a 2 Marriages. From 1st wife my father was born but after few years she died later my grandfather had 2nd Marriage from which I have 3 Uncle and 1 Aunt (Bua). After 2nd marriage of my Grandfather, my father had not a good relation with My Grandfather and New Grand Mother. Therefore he started living alone with My Mother. But in 1996 My father died and in 2005 my Mother also died. My Grandfather is not having good relation with me too. My Grandfather has got property from my Great Grandfather. What is my right in my Grandfather ancestral Property ?
