What share can grandson claim in ancestral property?

I was born in 1993. My grandfather had 3 son and two daughter. My father is the second son of my grandfather. My grandfather purchased some property in mehroli and later on in 1998 he sold it to my aunt(taujis wife) and died in 2000. At that time I used to be 5yrs old.ie.minor. At the time of such sale,no noc was taken from me or my guardians. And in 2015-16 we came to know that my aunt has further sold this property to someone else. I just want to know whether we can file a suit against them and get them arrested or be compensated for the loss of share and moreover is there any provision or law available to file request for division of family property amongst grandsons and son in court of law as after the death of my grandfather all the family affairs are managed by my grandmother and she lives with my uncle and aunty. They will never let her to give some share to us and moreover she herself is not interested in doing something in our favour.
