Yes, you can open and operate the bank account without any nominee. However, we recommend that you add a nominee right now or after some time as this is important.
If the nominee is less than 18 years as of today, then we would require Guardian details as well, which you can input after you put in the date of birth of the nominee.
In the case of an unforeseen event, the nominee will be allowed to access the funds in your bank and/or investments without the need for legal formalities such as a succession certificate, letter of admission, or court order.
We recommend that you upload nominee details while you open the bank account. However, you can upload nominee details later as well from your account settings.
