Changing your name legally in India requires a Gazette notification for name change. This is a crucial and official step that involves publishing your name change in The Gazette of India. It serves as legal proof of your new name and is necessary for updating all your official documents like your passport, Aadhaar card, and bank records. The process typically involves creating an affidavit, publishing an advertisement in local newspapers, and submitting the required documents to the Department of Publication.
