Hello Aastha,

Yes, it's okay to use your mother's name as per the Aadhaar card, "Mamta Walia," while filling out the JEE application form. However, during document verification or counseling, there could be a discrepancy between the 10th marksheet and Aadhaar card. To avoid future issues, keep an affidavit or a notarized document ready explaining the name difference, or get it corrected in either document if possible.
