We have purchased agricultural land in Maharashtra 35 years back. At the time of purchase or thereafter the area was never measured. Ever since we are cultivating the land peacefully within the boundary marks as mentioned in the sale deed without any objection from any corner. The seller had left the village and died long back. Now his son appeared and got the land measured from Govt. authorities. The surveyor told that we have excess land in our possession belonging to the seller. In this situation I request the forum to opine whether after lapse of 35 years the son of the seller has right to demand possession; whether we have right of adverse possession? and how to proceed to protect our interest. Early response will be highly appreciated.
