Dear Sirs,
Request your valuable input on legal provisions if the genuine owner of a land has lost the purchase deed
(Scenario 1: he might be able to trace a photocopy)
(Scenario 2: he does not even has photocopy)
(a) how can he protect his legal title?
(b) how can he prove his ownership and
(c) how can he sell the land and how to satisfy the prospective buyer?
Your valuable inputs will be highly appreciated.
Regards,
