Bankers have a duty of secrecy to keep their customers' affairs confidential, even after an account is closed or the customer passes away. This duty is a legal obligation, and breaching it could result in damages. There are some exceptions to this duty of secrecy, including when disclosure is compelled by law, such as responding to a court summons. Disclosure may also be allowed where there is a duty to the public or where the bank's interests require it, such as informing a guarantor when trying to recover debts. Disclosure with a customer's express or implied consent is also permitted.
