The most crucial step in the legal Name Change Process for updating the Aadhaar identity is securing the Gazette Notification for Name Change. This official government publication serves as irrefutable legal proof that an individual has formally and legally changed their name. For a complete Aadhar Name Change, particularly a first or full name change, the UIDAI often mandates the production of this Gazette for Aadhar Name Change at an Aadhaar Enrolment/Update Centre. This mandatory document streamlines the process of executing the Name Change in Aadhar Card and is accepted nationwide as official validation of the new identity for all subsequent document updates.
