I’ve noticed a difference in my father’s name on my 10th standard certificate and birth certificate. It’s Ashwani Kumar Puri on the 10th certificate, but simply Ashwani Kumar on the birth certificate. How do I get this corrected so all my documents, including my 12th standard certificate, have the same name?

You’ll need to approach the issuing authority of your 10th standard certificate (likely your school board) with an affidavit from your father confirming the correct spelling of his name as “Ashwani Kumar Puri”. This affidavit will be used to request a name correction in your 10th certificate, which will then be used to correct your 12th standard certificate and other documents.
