How to register ancesteral property in my father name?

This is Apparao. I am requesting this querry on my wife's name. we have an ancestral house and aggreculture property which was in the name of my Paternal Grand mother. he died i n 2005, after her death, my father and my uncles did not initiated any formalities to get the title of the house, site and agriculture land in the name of my father. few years back one my uncle too died. now i want to get share of the house registered in the name of my father and three of my uncles, one alive aunt. We gave our grandmother death certificate. My uncles' are well settled and they are in urge need of money, so they are helping to resolve this issue. each time they are escaping. Even they are not signing on the mutual concern agreement document too. Giving trouble each time gathering. My father also too old (around 67 yrs) My father has three daughters, i am one of them. if something happend to my father, being women, we cannot do anything. I need to get my father's share on his name. So, what civil procedings i need to follow to legally. Apparao V V
