A gazette notification is a vital legal document for anyone undergoing a name change process, especially for a name change in Aadhar card. It provides legal proof of the new name, which is a mandatory requirement by the UIDAI to ensure the accuracy of the updated information. The process to obtain this gazette notification for Aadhar name change involves submitting an affidavit, publishing a newspaper advertisement, and providing other necessary documents to the Department of Publication. This notification is essential for getting your new name legally recognized and updated across various government and private institutions.
