Our society transferred the 100 % share in the name of wife after the death of the member who was also nominee of the member. Widow (wife of deceased member ) duly nominated her only son. The son died intestate. Now under provision of Section 10 of Hindu Succession Act 1956 ,it has been assumed 50 % share of deceased son and class I heirs of deceased son mother (widow) ,wife,two daughters have made release deed favouring wife of deceased son i.e.daughter -in -law of widow and now she has applied for 50 % share rights in property . Can society accept such claim. Please guide.
