Procedure for partition of grandmother's ancestral property equally.

My grand mother died 2 months ago.As my father used to work in Odisha my grand mother used to live with my uncle (elder brother of my dad).My father has retired now and came back to our ancestral house with my mother one year back. Now seeing the attitude of my uncle we doubt he might have got the property written in his name by my grand mother. If our assumption is correct then according to Indian law can my parents get their share of property?my grandfather died long ago. I live in kolkata and is hindu by religion. I am married also and only girl child of my parents.
