My father has taken housing loan for carrying out further construction in his house from a PSU Bank. The house was in the name of my mother and my father was a co borrower. My father could not repay his debts and now after the death of my father, mother and gaurentor the bank has served me, my brother and sister the notice to repay the loan( the bank has already auctioned the house). Do in any way we are liable to repay this debt
