Me and mrs 2sheikhs have had a joint account for years. However, after so many arguments about money, I decided to open my own account and just give her money to cover the bills etc, every week. The bank wrote to her stating in the letter, "as you are probably aware, your husband has opened a new current account but still has access to the funds in your joint account". They then went on about it being an opportunity to try online banking. Are they allowed to divulge personal information like this?
