cooperative housing society

In Mumbai, a CHS for more than 55years was made up of Catholic members as the building was constructed with that intention. However now one of the members has taken token money and intends to carry on with the sale to a member who is non Catholic Secondly, a member of the CHS had expired more than 40 years ago. Some of his children too have expired, while two are living. However the names of the grandchildren (offspring of the expired children) and the names of the surviving children are appearing as members of the CHS. Is this permitted? Thirdly, if a member of CHS expires, does the spouse and child have equal rights, if nomination papers are missing?
