We have a land and the size mentioned in sale deed is less than the actual size. May be this happened due to wrong measurement or mistaking while preparing document. My grandfathers bought this 47 years back (year 1976). Now other people encroached the extra part as that is not in paper. the land size as per sale deed 27 X 36 feet. Actual size 30 X 36. The land was grama natham, and during the UDR land survey(year 1992) This 3 feet is included in the patta copy and FMB in my grand father name only. In the village record (VAO office record A register) also having in my grand father name only. but the surrounding people argue with us and he is claiming the extra land. He is not having any proof of this extra land. As per the boundary mentioned in the sale deed this extra land is not included in the neighbors land. My question is who is the owner of this extra land ? Is it that our neighbor and us have 50:50 share ? Or we are the sole owner ? What laws say in this case ? If we want to reclaim that extra part what should we do ?
