When a flat owner passes away, their nominated daughters inherit the property. The housing society can transfer the share certificate to the daughters based on their nominated shares (70% and 30%). However, the society cannot determine the final title; this must be settled by legal heirs or a civil court. Until the title is clear, the daughters are jointly responsible for maintenance and property tax. If the property is sold, the proceeds should be divided according to their legal inheritance shares, not necessarily the nomination percentages.
