Hi aspirant,

Yes, in general affidavit is accepted by most of the counselling bodies in order to rectify unintentional mistakes during the process. For the issue you have mentioned, you need to carry a self attested affidavit claiming that both the persons are same and it should be supported with legitimate proofs and documents. In general cases like these are generally approved by the verifying officer and you are allowed to proceed with the admission procedure.

Hope it helps!!
