I am trying to buy resale flat . society is formed in 1990. builder and land owner had made conveyance deed but it has not been registered yet. Society has only Xerox copy of that conveyance deed . When I asked to flat owner he told me that due to non payment of stamp duty it has hold.they are trying to extract original copy. My question is that whether they get conveyance or not .if I buy flat then it will be impact in future. Please guide me.
