Name change

There are three mandatory things, which are needed to be done for authorizing the name change:

1. Affidavit Submission: An affidavit needs to be prepared for name change.
2. Ad Publication: An announcement should be published in the newspaper.
3. Gazette Notification: A notification should be published in the Gazette of India regarding the name change.

Thank you Sir..

First do I need to take permission from my PSU ?
