i have 2 brothers and 3 sisters. after my mother's death in the year 2003, my second brother took the signatures of me and my elder brother on white paper and asked us to sign on palu patra written on 10 rupees stamp paper and told us it will help him to get any crop loans etc., believing his words we both have signed. Recently he died and when i asked my portion of land and house, my sister in law says she can't part anything from my father's self acquired property. my brother did not take any signatures from my sisters during palu patra. and it is not registered by us also. but got all land and house transfered in his name and done the mutation from local authority. please guide me
