You will need to have a payment account for individuals with BBVA. Keep in mind that corporate accounts and those intended for commercial or professional activities are excluded.
The account holders of the recipient and source account must be the same and the transfer application must be signed by each and every one. The other bank may refuse the transfer if the general conditions of the service are not fulfilled. It is also possible that balance transfers may be denied when the source account has direct debit payment commitments.
On the transfer request form, you have to specify what information you want BBVA to request from your other bank and what it will be used for. And if you want, you will receive a copy of the information that is exchanged between the banks.
If you want to close your previous account, you will have to return any cards, checks, passbooks, etc. that are in your possession to the original bank.
A balance transfer will result in the original account being closed. Partial transfers will not be accepted. It's free and it is started by the source bank on the date you specify.  It may take a few days for your account to be credited
Any transfer you make between the source account and the destination account outside the transfer process may entail a fee.
You have to keep a sufficient balance in the old account until the transfer is complete.
