To change the name in the Aadhaar card, visit your nearest Aadhaar Seva Kendra. Fill the form to update your name there. To update your new name, you have to submit the gazette notification, which is a legal document certifying your name change. After this, you have to pay a fee of up to Rs 100 to update the name in the Aadhaar card. After filling the form, you will get a slip with a number written on it so that you can track your process. For more information about the gazette, you can contact some agencies like Advocate Advice or Vakil India, which have been helping people to publish name changes in gazette notifications through their name change service for many years.
