My father has 3 sons. Last 4 years of his life he stayed with my family. He expired and in his un registered will , which has doctor's certificate & 2 witnesses, I and my children are sole beneficiary of all his monies which consists of
1) FDR of Rs.10 Lacs held with me as second holder & having either or survivor option.
2) PPF having my name as Nominee
3) Bank Shares having my name as Nominee.
4) about 10 lacs deposited with my children.
The other 2 sons are objecting to the fact that my family is sole beneficiary.
What action should I take ? Withdraw FDR & PPF a/c and transfer shares without probate ? please advise
