dealing with difficult situations

Most of the complaints the ombudsman sees involving power of attorney are about lost documents, administration and misunderstandings about what powers the attorney has been granted.

These situations can be very upsetting. But they can often be resolved quickly by following our guidance for businesses and consumers.

Where a complaint involves family disputes or problems involving the donor’s mental capacity, the situation can be particularly complex and distressing. There are rarely any easy answers - and we sometimes decide it’s more appropriate for the issues to be resolved by the courts. We'll also suggest that you speak to the Office of the Public Guardian, who can mediate in these situations. They'll make the necessary enquiries and decide the best course of action.

dealing with complaints about mental capacity

A power of attorney gives someone the authority to make decisions about your finances and legal affairs, and/or your health and care options. You may choose to do this if you’re concerned that you might lose mental capacity in the future - for example, because of dementia or an accident.

However, the donor - the person covered by the power of attorney - is generally still able to manage their own finances, as well as the person they’ve appointed to act on their behalf. This can result in problems if the donor is starting to lose their mental capacity.

On one hand, the attorney - the person acting for the donor - might feel that the donor is no longer able to make their own decisions, and complain that a business shouldn’t be taking instructions from them, particularly when they know their customer is unwell.

On the other hand, the donor is legally entitled to make their own decisions about their own money until it’s formally decided they don’t have the capacity to do so.

Understandably, these situations can present an ethical dilemma. The bank has an obligation to act in the best interests of their customer. But they must also balance the rights of the donor against the attorney’s concerns for their wellbeing. The ombudsman wouldn't expect bank staff to be forced to make these difficult decisions. In situations where financial abuse is suspected, the Office of the Public Guardian can talk you through the options.

Here’s who you'll need to contact in these situations.

During this process, financial businesses can help by making sure the donor’s finances don’t go in to the red - and where possible, any regular payments agreed before the donor lost mental capacity continue to be made.

family disputes and acting in the donor’s best interest

When a donor is unwell, or losing their mental capacity, family members who aren’t appointed as attorneys might sometimes try to make complaints on the donor’s behalf. This could be because they believe that someone has misled the donor - by mis-selling an investment, for example. They might also object to the actions of the attorneys themselves.

Family disputes are difficult to resolve, as banks are only able to provide information to their customers or their official representatives. The same rules apply to people who bring their complaints to us.

Though a financial business shouldn’t act on unproven allegations made by other family members, they do have a duty of care to their customer. So if the business thinks a power of attorney is being abused, they should report it to the relevant authority. They might also decide to refuse to carry out some instructions - like transferring of money from the donor to the attorney’s account.
