Investing rules for attorneys and deputies

If you manage someone else's money under a power of attorney or a court order, what are you actually allowed to do with their investments? This explains the rules on keeping money separate, taking advice, recording decisions, and what happens if an investment loses value, plus who to contact if you think an attorney is misusing someone's money.

Investing rules for attorneys and deputies

If you hold a lasting power of attorney for someone's property and financial affairs, or you have been appointed a deputy by the Court of Protection, you can make investment decisions on their behalf. But the rules are tighter than for your own money. You must act in the person's best interests, keep their money separate from yours, and stay within the powers you have been given. You cannot delegate investment decisions to a fund manager unless the power of attorney document or court order specifically allows it1.

The core duty is straightforward: an attorney has an obligation to act in the best interests of the donor and not to benefit themselves2. A deputy can only act within the authority set out by the Court, and has a duty to act in good faith3. Everything else flows from those two principles.

This page explains what attorneys and deputies can and cannot do with investments, how to take advice, what records to keep, and where to get help if something goes wrong.

What attorneys and deputies can and cannot do with investments

A lasting power of attorney for property and financial affairs covers debts, mortgaged property and investments6. An enduring power of attorney covers decisions about finances or property and investments7. In practice, this means an attorney can buy and sell investments, move money between accounts, and manage an existing portfolio.

The limits matter as much as the powers. You do not delegate decisions to an investment fund manager unless you have permission within the LPA, EPA or court order1. If the document is silent on delegation, you make the decisions yourself. A deputy faces the same restriction: they can only act within the authority set out by the Court, and they have a duty to act in good faith3.

There is also a distinction between types of deputy. There are two types: the property and financial affairs deputy and the personal welfare deputy3. Only the property and financial affairs deputy deals with investments.

For attorneys, the scope of decisions can include selling the person's home, paying their mortgage and bills, and arranging repairs2. Investment decisions sit alongside those responsibilities, not above them. If the person needs cash for care fees, that may take priority over keeping money invested.

A lasting power of attorney sets out what an attorney can do; a deputyship order sets out what a deputy can do.

Acting in the person's best interests

Best interests is the test that runs through every decision. As an attorney, you have an obligation to act in the best interests of the donor and not to benefit yourself2. Attorneys appointed under an LPA must act in the best interests of the individual8.

What does that mean for investments? It means considering the person's circumstances, their income needs, their care costs, their attitude to risk before they lost capacity, and any instructions they left in the document. It does not mean chasing the highest return. It does not mean putting money into something you would choose for yourself.

The Financial Ombudsman Service has considered cases where a bank failed to explain investment options properly. In one case study, compensation was awarded after a bank failed to fully explain investment options9. The ombudsman looks at whether the consumer wanted capital protection, their investment objective, attitude to risk, affordability, and where the investments were made10.

For attorneys and deputies, the same principles apply. If you are making an investment decision for someone else, you need to be able to show that you considered their needs and circumstances, not just the product's potential return.

Attorneys: following the lasting power of attorney

The lasting power of attorney is the document that defines your powers. You can appoint as many attorneys as you like, and replacement attorneys8. If more than one attorney is appointed, the document may say whether they must act jointly or can act separately.

An LPA for property and financial affairs can be used at any time after registration4. You decide when you want this type of LPA to start; the attorney must have your permission to act while you still have mental capacity8. This is different from an enduring power of attorney, which an attorney can use while the donor still has mental capacity even if it is not registered7.

Registration is not optional for an LPA. An LPA must be registered with the Office of the Public Guardian before it can be used4. Either the donor or the attorney can register it11. The forms must be signed in a particular order: donor first (witnessed), then certificate provider, then attorney (witnessed); otherwise the LPA will be rejected8.

For an EPA, the rules differ. If the donor loses mental capacity, the attorney must register the EPA to start or continue using it12. The attorney registers it with the Office of the Public Guardian when they think the donor is beginning to become unwell or already lacks capacity to manage their own finances11.

Once registered, an attorney must involve the donor in making decisions wherever possible, only make decisions the donor cannot make themselves, and follow any instructions in the EPA12.

Deputies: the limits set by the Court of Protection order

A deputy is appointed by the Court of Protection, not by the person themselves. If someone does not have mental capacity, the Court of Protection could give you the right to make decisions for them, and could make you a Deputy13. The application process involves the Court considering whether it is necessary for ongoing decisions to be made on their behalf, and whether the person applying is suitable3.

The key difference from an attorney is that a deputy's powers are set out in the court order, not in a document the person signed. A deputy can only act within the authority set out by the Court, and they have a duty to act in good faith3. If the order does not mention investments, the deputy does not have investment powers.

There are two types of deputy: the property and financial affairs deputy and the personal welfare deputy3. Only the property and financial affairs deputy can make investment decisions.

If money is held in the Court Funds Office or is administered by a Deputy appointed by a Court, it is administered by a Court14. This means additional oversight applies.

A deputy who wants to invest beyond what the order allows must apply to the Court of Protection for permission. The Court will consider whether the proposed investment is in the person's best interests.

Taking financial advice before investing

Attorneys and deputies can take financial advice, but the decision remains theirs.

There is no general rule that an attorney or deputy must use a financial adviser. But some products require advice. Before purchasing an equity release product, professional financial advice is required, and the adviser must be qualified15.

If you do use an adviser, the adviser has duties too. A firm must ensure all advice given and action taken has regard to the best interests of the customer, is appropriate to the individual circumstances of the customer, and is based on a sufficiently full assessment of the financial circumstances of the customer16. Both independent financial advisers and restricted financial advisers must agree up front how much you will be charged for their services, when you will be charged and how payments will be made to them17.

Finding an adviser can be done by searching online, checking specialist investment publications, talking to your accountant or solicitor, checking the investment pages in major newspapers, or contacting trade bodies18.

Before investing, make sure you have some "rainy day" money. Keep an appropriate amount of cash in a bank or building society so you can access it quickly for any unexpected outgoings or emergencies19. For someone else's money, the same principle applies: their immediate needs come before investment growth.

Keeping the person's money separate from your own

Attorneys must respect confidentiality, follow the donor's instructions and preferences, and keep their money and property separate from their own2. This is not optional. Mixing the person's money with yours is a breach of duty.

The principle applies to investments as well as bank accounts. If you buy investments for the person, they should be held in their name or in trust for them, not in your name. Some products allow investment in trust for someone else20. Others allow investment in your own name or jointly with one other person, but that is for your own money21.

Keeping savings separate can make it easier to see growth and reduce the temptation to spend22. For someone else's money, separation also makes it easier to show what you have done if questions are asked.

The same safeguarding principle applies in other financial contexts. Money transfer firms must separate client funds from their business funds23. E-money and payment services providers must hold funds separately from the firm's own funds, typically with a bank24. Individual Savings Accounts and Child Trust Funds legislation provides additional safeguards for investors25. The principle is consistent: client money is not the firm's money, and the person's money is not the attorney's money.

Records, reports and supervision by the Office of the Public Guardian

Attorneys should record important decisions and when they make them, and the donor's assets, income and how they spend their money2. This record serves two purposes: it helps you make consistent decisions, and it provides evidence if your actions are questioned.

The Office of the Public Guardian has a responsibility to investigate allegations of mistreatment or fraud, and can report concerns to the police or social services if necessary8. The relevant authorities can request information about how you use power of attorney and check your decisions2. They may arrange a visit or contact people who know the donor2.

For enduring powers of attorney, there are specific retention rules. Do not send the unregistered EPA and deed of revocation to the Office of the Public Guardian; you need to keep them12. Enduring Powers of Attorney do not need to be registered with the Office of the Public Guardian before use, but they must be registered once the donor lacks capacity26.

An LPA must be registered with the Office of the Public Guardian before it can be used4. This is done through the Office of the Public Guardian11.

If something goes wrong: concerns, complaints and getting help

If you think an attorney or deputy is misusing someone's money, the Office of the Public Guardian has a responsibility to investigate allegations of mistreatment or fraud8. They can report concerns to the police or social services if necessary8.

The Financial Ombudsman Service can consider complaints about power of attorney28. If you have lost money because you received the wrong investments advice, the ombudsman will tell the firm involved to put things right and pay compensation for distress or inconvenience10. The ombudsman looks at whether the consumer wanted capital protection, their investment objective, attitude to risk, affordability, and where the investments were made10.

If you pay for regulated financial advice and it turns out to be poor, including if you lose money as a result of bad advice, you can complain and ask for compensation29. But you will not be compensated for investments falling in value, or a company in which you hold shares going bust, unless this resulted from bad advice by a regulated Independent Financial Adviser that has since gone bust15.

The Financial Ombudsman Service decides complaints using relevant law and regulations, regulator's rules, guidance and standards, industry codes of practice and good industry practice at the time of the event30.

If you are concerned for your safety, contact the police for information and support31.

Frequently asked questions

Can an attorney move someone's savings into investments?

Yes, an attorney for property and financial affairs can make investment decisions, including moving savings into investments, as long as it is in the donor's best interests and within the powers granted. The attorney must follow any instructions in the lasting power of attorney and keep the person's money separate from their own. They cannot delegate investment decisions to a fund manager unless the document specifically permits it.

Does a deputy need permission from the court to invest?

A deputy can only act within the authority set out in the Court of Protection order. If the order does not give investment powers, the deputy must apply to the court for permission. The deputy also has a duty to act in good faith and in the person's best interests, and cannot go beyond what the order allows.

Do I have to use a financial adviser as an attorney or deputy?

There is no general requirement to use a financial adviser. However, some products, such as equity release, require professional financial advice before purchase. Financial advisers must agree their charges up front. If you do take advice, the adviser must act in the customer's best interests and base recommendations on a full assessment of circumstances.

Can I keep investments the person already held before losing capacity?

Yes. An attorney or deputy can maintain existing investments. An enduring power of attorney can be used while the donor still has mental capacity even if unregistered, but must be registered with the Office of the Public Guardian once the donor loses capacity. A lasting power of attorney must be registered before it can be used at all.

Can I invest the person's money in my own name?

No. Attorneys must keep the donor's money and property separate from their own. Investing in your own name would breach that duty. Some products, such as NS&I Guaranteed Income Bonds, allow investment in your own name or jointly, but that is for your own money, not someone else's. For someone else's money, it must be held in their name or in trust for them.

What happens if an investment I made for someone loses value?

Investment values can fall, and there is no compensation simply because an investment lost money. You will not be compensated for investments falling in value unless poor performance resulted from bad advice by a regulated independent financial adviser that has since gone bust. The duty is to act in the person's best interests, not to guarantee returns.

Who do I contact if I think an attorney or deputy is misusing someone's money?

The Office of the Public Guardian has a responsibility to investigate allegations of mistreatment or fraud and can report concerns to the police or social services. The relevant authorities can request information about how power of attorney is being used and may arrange a visit or contact people who know the donor. You can also contact the Financial Ombudsman Service about investment complaints.
