Hi, i want to purchase a flat which falls under the landowner's (one of)share in Kolkata. The owner of the land is no more. His legal heirs, (total 7) entered into an agreement with a builder to develop on the land, a residential complex with 50% owner's share& executed a deed to that effect. The land is properly registered & mutated in the name of legal heirs. When i went to SBI for loan application, they informed me that to sell his portion, the landowner must first register & mutate the flat alloted to him by the builder along with all the other landowners. Is it true? AND what type of registration is this. I mean, what is the document actually called. Kindly help me out.
