A man received an extra bigha of ancestral land due to a mistake in a partition deed signed by him and his four brothers in 2000. Now, 21 years later, as the land is being sold, the buyer intends to pay him for the extra bigha directly. However, his brothers are demanding an equal share of this money, threatening legal action if he refuses. The man is seeking advice on whether his brothers have a legal right to claim this land, especially since the partition deed was drafted by them and they took the better plots.
