1) Deed of Assignment is done in 1970
2) In Deed of Assignment some Judgment is mentioned and that case we tried to trace but we failed to even get record of that case . So puzzle is whether that case took place or not , I think again restart the process of search is required.
3) That land is not with the legal heirs of person who got rights from deed of assignment but his uncle is in possession who is no ready to give possession.
4) The land ownership is transfered from one builder to another and all builders are fighting between themself that they are cheated by previous builders. Means Builders have lost in crores on this land. and each person in chain is trying to sell the land to new builder so his locked investment he gets back
5) On Land record it is mentioned Eccumbrance (E) - in name of person who got right through Deed of assigenment
What you will suggest advice for Legal heirs of those who got right from deed of assignenment
