In the year 2000 ,we 5 brothers made partition deed of our Ancestral agriculture land and it was signed by all 5 brothers and also registered in sub registrar office.actually at that time i got 1 bigha of extra land compare to the other 4 brothers by mistake.and they all signed the partition deed and also registered in sub registrar office.now in 2021, we 5 brothers are going to sell this land so the buyer tell me that he will give the money of my 1 bigha extra land to me only in my hand instead of giving it to the rest 4 brothers because that land is on my name currently.but my 4 brothers tell me that you have to make 5 parts of this money which you will recieve from buyer otherwise they will file case against me in court.so i want to know now it is possible for them to claim this 1 bigha land if i am not giving the money of this 1 bigha extra land to them?
