If you're looking to complete the name change process, you absolutely must obtain a gazette notification for name change. This notification is an official government document—essentially an official notice of laws, regulations, government changes, and public information. The purpose of a name change is to formalize it through a legal process. To achieve this, you need to get your name changed in the Gazette of India. This official publication then serves as the legal proof and evidence of your name change.
This gazette notification will help you get your name updated in the rest of the documents. It is a legal record of the change, which is vital for resolving any future obstacles and provides necessary legal reference.

To start this official process, you will need:
Any Government ID Proof
2 Passport Size Photos
Affidavit prepared for name change
CD Format (digital copy of the text)
To start the Gazette name change process, first gather your necessary documents. These will be compiled into a file and submitted for the Gazette Notification.
Here are the basic steps you'll complete:
Affidavit: Prepare an affidavit for your name change, detailing your old and new name.
Newspaper: Get an advertisement for your name change published in your local newspaper. This acts as a public announcement.
CD: The text prepared in the affidavit must be typed in MS Word and saved in digital format on a CD.
Payment of Fee: You must pay the required fee for the issuance process and keep the receipt safely.
Gazette Notification: Prepare a complete file including a copy of the newspaper clipping, the affidavit, the CD, the fee receipt, and other necessary documents. Submit this name change application to the gazette notification office by post/courier or in person.
Once the file is submitted, it goes for verification. If everything is in order, your name change is approved. The Publication Department will then publish the name change in the gazette notification. This entire process typically takes 25 to 30 days to complete.
