a person with four married daughter - without issue, died on 02.09.2009. He had made will duly notarise but same is misplaced/misappropriated by one of his sister. She has with her son prepared fake will with the help of Notary/Advocate and produced xerox copy of will in which executors as well as witness both are same. Now they have tried to encash the FDs in the name of other sisters on the ground of nomination but caught by the banks. Now other parties want to challange the will. Can they ???
