The deduction u/s 80E is available to the assessee for the payment of interest on education loan taken for his higher education or his relative, i.e., the spouse and children of that individual or the student for whom the individual is the legal guardian.
You may decide who should get the benefit of the deduction u/s 80E, whether yourself or your parents/spouse/children.
You may take a certificate from the bank every year for the payment of interest on the education loan during the financial year. This should suffice.
