I've just finished a 3 year course and have paid the Uni fees using my mum's CPF. However, I know once she turns 55, she'll be able to waive it off so that I do not need to pay back in the CPF Acc.

As my mother is only turning 55 in about a year's time and that repayment cycle of the Uni fees back into her CPF has started, is it okay to just defer payment until she is 55, so that she can waive off? I've emailed CPF since April, and till now they said they're "addressing it". Mum also don't want me to pay back into the CPF
