Hi, My Grand mother died in 2000. She has share in maternal property, my father and my uncle are the two leagal heirs. My father had submitted affedevit for registration of leagal heirs after their mother's name in specific KHATA number i.e. 284 of property(land) on 17/4/2004 (for Hakka sod patra purpose). on the same day my father had sign HAKKA SOD PATRA(Relinquishment of rights) withouth any considration/money/mobadala. later on we came to know that the affedevit which he had signed had wrong KHATA number the correct number was 284 in affedevit 184 was mention. now the question is - is Relinquishment of rights is valid or not because the name of leagal heir was not registerd because of wrong khata number/gat number in affedevit. can we challage the Relinquishment of righs which was signed on same day, as there are no names included in proprty because of wrong Khata number and we did not receive any money against that.
