Can i claim the proprety since 1955 in permissive possesion

Hi sir Dear sir the property in the name of my great grandfather. He was passed without any will. He had two sons (my grandfather and his brother) also not partition the property passed they have blessed one son. my father was gifted 1/4 of land to my mother in 1956 due to ill health (i am in my mother womb). my father was passed in 1961 when i am 5 years old. the remaining part of the property was occupied (permitted by my grand mother )and enjoyed by my father in laws(my mothers father & 4 uncles). total 1/2 of the property enjoyed from 1956 and sold a part of the property without any right. my mother and grand mother (sister of my father in laws) supported to their relatives. i don't know this information because my mother told me they are all our family members so the property was shared equally. But now we identified (my son) that the property belongs to my great grand. they are not having any registers documents relating to property. but they get patta passbook in 1995 and enrolled in revenue records. The property in permissive possession. Now can i passable to sue the property in the court. For declaration of title. Please give me your valuable ideas thanking you sir
