While renewing my passport, can I change my name?
No, it is a complex process. Depending on the country in question, it involves various formalities. As far as India is concerned, you need to swear in an affidavit and advertise the same in 3 newspapers that are in wide circulation in your area: English, Hindi and the official language of your state. Next, you need to have a gazette notification of the same published in the weekly ordinary gazette of India. You need to submit all of these to the Regional Passport Office of your state and complete the other formalities.
