Apartment owners association

Hello Sir/Madam, I am living in a apartment. The owners association is formed my non owners( eg: relatives of owners are members) and association still a run by few people and no cooperation from all people because it formed by a small set of people and no support from many of the owners. After 3 years now, we All owners discussing to form a new owners association with more of 80% of the owners as members. We also thinking to form individual owners association each block and share the expenses like stp, club house etc, then how can builder handover the commen amenities to association when every block is having its own owners association. Is it valid to form a new owners association when existing so called owners association formed by non owners in place. Is it possible to form owners association each block as I we xplained ? A basic question, Is it valid that a son/daughter can be a member or office bearer of owners association when the flat is name of dad. Is it valid Dad /Mom can be a member or office bearer of owners association when the flat is in name of son/daughter ?
