We are a Hindu family. My grandfather (Mother's father) had a land and died without any will so the land has to be divided equally between my mother and her siblings. 2) Now without giving my mother her share her siblings have built houses in that land and have given it for rent. We have filed a case already for partition suit but i want to stop the rents that they are getting. How do i do this? 3)I was told that i need to get the tenants names and submit it to the court to send them notices but i cannot get the tenants names as my mother's siblings stay there and they may harm me if i try to go and speak to the tenants.
