I have purchased a flat in 2017 in a society which is basically a Ltd.Co. (Seawoods Estates Ltd in Nerul, Navi Mumbai). The previous owner is settled in UK. Now the society is insisting to get the shares transferred into Demat account first in the name of the previous owner and then into my name and only then they will issue me a NOC for selling this property. In the absence of the previous owner how can I get the shares transferred into my account in demat form. Do I have to furnish any affidavit from the previous owner for the same.
