Flat owners in a West Bengal building, whose promoter has failed to form an association for over 40 years and neglected maintenance, are seeking to form their own association. The process involves convening a general body meeting of all owners, passing resolutions to form the association and elect office bearers, and then registering it with the Registrar of Societies. It's crucial to follow the West Bengal Apartment Ownership Act, 1972, ensuring at least seven members above 18 years are involved and all necessary documentation is prepared.
