My father had made youngest son as nominee in his accounts and he along with elder one is not dividing the entire money. They both have decided to keep the entire amount and are forcing me to vacate the ancestral home on which we three are currently living together. It's been 2 years since father has left us and both of my brothers without informing anyone have claimed all the amount except one account which they are still not claiming in the bank.
