It is not possible to use another person's bank/PIX account to make a withdrawal. The associated bank account must have the same CPF as the one registered in your Betano account.
Please note that deposits must also only be made through bank/PIX accounts in the name of the Betano account holder, otherwise they will be returned.
You can read more about this in points 3.2 and 4.11 of our Terms & Conditions
