What is your father's original name? You can change your father's name in your adhaar card using your marksheet as proof.

however you cannot change your father's name on his aadhar card.

if your father's original name is bhadur singh then their will be no problem for you. However if your father's original name is bahadur singh, then you will have to live with your father's wrong name for rest of your life unless you change names on your certificates which will require court interference and legal process.

Hello,
.
Don't be worried about the problem.
Just visit the nearby post office, mee seva  or E-seva and tell them the issue you have or tell them you have came for Aadhar correction.
They will help you out in Aadhar correction.
.
If you are from Hyderabad you can visit nearby banks , even banks are providing facilities for Aadhar correction, if they say they don't have such facilities ask them which bank is providing such facility, they will let you know about it.
.
It will take nearly 15 to 30 days for correction.
So, do it as soon as possible. So that you won't face any problem.
.
Thank you
