Legal Question in Banking Law in India

it is incorrect. the daughter's remedy is to make her claim before the bank or she should file an application for succession certificate before the Administrative Civil Judge for the deposit. Meanwhile she may obtain a stay on the release of the amount in the same case.

Yes this is true. The legal heir of the deceased son has no right .

the legal heir of the deceased can claim from nominees and not from the Bank.

Nomination recorded by the bank must contain % of amount available to the nominees.If not all the three will get equal share of maturity value of deposits i.e. 33.33% each. Elder son's daughter has right to take the custody of her entitlements provided she produce the succession certificate and undertakes to dispose the money as per will of deceased grandfather or as per succession certificate obtained by heirs of the deceased grand father. Please note nominees get only possession of the deposit amount and not ownership
