If the transfer of business name from your mother's name to yours will not make any complications as to the date of transfer then i guess it is ok but, if the date will appear and then you'll submit that as additional documents do you think they won't notice it? I also had the properties under my parents name but i submitted them as it is and then together with the tax declaration of properties and the extra juducial partition of properties. It says to submit an evidence of bank account. An ATM and a passbook are one of those. Having a passbook account means your money is really intended for savings which means you got a lot hence you seldom make withdrawals. With the ATM account which has the regular movements (like withdrawals and deposits) which only means intended for small amounts. If you have invested in Time Deposit or any other kind they are also considered. The more evidence is better.
