Land ownership dispute

file declaratory suit and pprove the facts you have mentioned ,

Before death, my grandfather had made a registered will. He has clearly mentioned in the will that one of his property (agriculture land) will be distributed equally between his two sons. My father was elder son and uncle is younger. My father died in 1991. Then after 2 years my grandmother died. Then my uncle started manipulating with the property along with one of our neighbours and we were unaware about it. My family includes my mother and I. I had a brother who is no more. He died at the age of 21 in 2002. Soon after my uncle had started manipulating with all our immovable properties along with the authorities concerned and my mother and I had no idea about it. now we came to know that he had divided the agriculture land in such a way that he is getting his entire share and in our share 1 Part is in my mothers name, 1 in mine, 1 in my brothers and 1 in my late grandmothers name. also, the he has sold the land which actually belonged to us and given us the other share of land which actually belonged to him. also, we are not given one complete plot. , rather it's two equal plots. But acc. to my grandfathers will the land had to be divided ony into 2 plots, one ours and second one of uncles. Also, he has sold his share to the same neighbour. He has done all these manipulations along with him as that person is a patwari. Pls help me.

Actually I was putting up my query and by mistake I typed it in somebody else's forum. It was not intentional.
