Banks ask their account holders to make nominations which mean that they should nominate persons to whom the money lying in their accounts should go in the event of their death. Nomination can be made in account opening form itself or on a separate form indicating the name and address of the nominee. The account holders can change the nomination any time. A nominee is only a custodian of the deposit and his/her responsibility is primarily to ensure that the legal heir of the depositor gets the money from a fixed deposit. He/ she  primarily becomes the operator of the account in the event of the demise of the depositor and does not actually own the money or have any legal right over the same.

Dear Client
To ensure that your investments are distributed according to your wishes, you may consider taking the following steps:

1. Nomination: Designating your mother as the nominee for your investments is a good first step. However, it's important to note that nomination does not guarantee that the nominee will have absolute control over the assets. The nominee is typically considered a custodian of the assets until they are transferred to the legal heirs.

2. Will: Creating a will can provide additional legal protection and clarity regarding the distribution of your assets. A will allows you to specify your wishes and designate beneficiaries for your investments. It's advisable to consult with a lawyer to draft a will that accurately reflects your intentions and is legally valid.

3. Legal advice: Consult with a lawyer to ensure that your will is properly drafted and covers all the contingencies you mentioned. They can guide you on the specific legal requirements and help ensure that your wishes are legally enforceable.

4. Estate planning: In addition to a will, you may consider other estate planning tools such as trusts, which can provide further protection and control over the distribution of your assets. A lawyer specializing in estate planning can provide guidance on the most suitable options for your specific situation.
