Quick answer
A UK Lasting Power of Attorney can be overridden in narrow circumstances by: (1) the donor themselves while they retain capacity — they can revoke the LPA at any time (form LPA001 to OPG); (2) the Court of Protection on application — where the LPA is invalid, the attorney is unsuitable, or the attorney is acting against the donor’s best interests; (3) the Office of the Public Guardian through a safeguarding investigation that escalates to the Court of Protection; (4) statutory bodies in very narrow scenarios. Importantly, family members do NOT have any automatic right to override an LPA, regardless of disagreement with the attorney’s decisions — concerns must go to the OPG or Court of Protection. Attorneys cannot override another attorney’s authority where the LPA is ‘jointly and severally’ — they have equal rights. The OPG investigates around 4,000+ LPA concerns a year. This guide explains who can override a UK Power of Attorney in 2026, the realistic procedures, and the protections built in.
Last reviewed: 24 May 2026 by the MP Estate Planning editorial team. Jurisdiction: England and Wales. Scotland and Northern Ireland have different probate and intestacy rules; the IHT thresholds are UK-wide.
Three rule changes you may need to consider (2026/27)
1. Pensions become subject to IHT from 6 April 2027. Most unused defined-contribution pension pots currently sit outside the estate for IHT — that ends on 6 April 2027 (gov.uk policy paper). HMRC estimates around 10,500 estates will face IHT for the first time as a result.
2. Business and agricultural property reliefs capped at £2.5m per person from 6 April 2026. Above the cap, only 50% relief applies — effective IHT of 20%. AIM shares dropped to 50% relief and do not use the £2.5m allowance (Saffery — APR/BPR reforms).
3. The NRB, RNRB and £2m taper threshold are frozen until 5 April 2031 following the 2024 and 2025 Budgets (gov.uk — NRB and RNRB freeze). With inflation, more estates will be pulled into IHT each year — a process commonly called “fiscal drag.”
In the UK, Powers of Attorney let someone, known as the donor, choose others to make decisions for them. But sometimes, these decisions change. When this happens, it may be necessary to cancel someone’s power of attorney. This can be done by the donor or by a concerned party, but not anyone can do it. It’s important to know who can cancel a power of attorney to protect the donor’s interests.

What is a Power of Attorney?
A Power of Attorney is a legal tool. It lets someone pick a person to make important choices for them. These choices can include money and health decisions. It depends on the type of Power of Attorney you pick. Knowing what this role involves helps keep the person’s interests safe.
Types of Power of Attorney
In the power of attorney UK setup, two main kinds exist: Lasting Power of Attorney (LPA) and Ordinary Power of Attorney. The lasting power deals with times when the person may not think clearly. It ensures their health and money choices are taken care of well. The ordinary power works for a short while. It’s used when someone else must handle your things for a bit.
Roles and Responsibilities
Picking the right attorney solicitor or trusted person is key. They will make choices about where the donor lives, their medical care, and money. It’s vital they can handle this job well and rightfully.
A good attorney solicitor looks out for the donor’s best interests. They make sure everything they do is open and honest. This goes for both the ordinary power of attorney and the lasting power. The attorney should do what the person wants and offer steady help.
Reasons for Overriding a Power of Attorney
In the UK, people may have to cancel a Power of Attorney due to serious issues. This might be because the person acting as the attorney did something wrong, or they can’t do the job right. It’s important to look out for the person who gave the power (the donor) and make sure they’re taken care of.
Misconduct by Attorney
Finding out an attorney has done something bad is a big reason to stop their role. This could include stealing, lying, or hurting someone. If someone notices the attorney doing these things, they should act fast to protect the donor’s money and health.
Attorney No Longer Capable
Another reason to stop an attorney is if they can’t do the job anymore. This could be because they’re sick, or they just don’t want to help. When this happens, it makes it hard to take care of the donor’s business. The attorney might need to stop working. In that case, it’s important for others to work with a legal group to find a new person to help the donor.
Legal Grounds for Overriding a Power of Attorney
Many factors need to be considered before overriding a Power of Attorney. It’s crucial to know these rules to act in everyone’s best interest. This provides a fair process for all involved.
Mental Capacity of the Donor
The ability of the donor is a key point for canceling a Power of Attorney. If the donor can think clearly enough to handle their finances, they can cancel the Power of Attorney. This means they can again use their financial power by themselves, without an attorney.
Bankruptcy and Financial Issues
Having sound financial health is vital when someone has Power of Attorney. If the donor or the attorney is bankrupt or in a money crisis, legal help might be necessary. This can happen when the attorney can’t handle the donor’s money wisely. The law steps in to protect the donor’s finances in these cases.
Problems in the employment law can also make an attorney unsuitable. It’s essential to keep the donor’s financial rights secure and make good decisions.
Processes to Override a Power of Attorney
Overriding a Power of Attorney is a big step in law. You need to know the steps well. This part talks about the key things to do. For example, filing a complaint with the Office of the Public Guardian is a must. Also, there’s the step where an attorney says they don’t want to be your attorney anymore.
Filing a Complaint with the Office of the Public Guardian
Feeling worried about your attorney’s actions? The first move is to file a complaint with the Office of the Public Guardian. They check to make sure attorneys are doing what’s best for you. When you complain, make sure to share everything you think is wrong. This includes any proof of bad behavior or if your attorney can’t do their job well.
Disclaiming Responsibility
Sometimes, an attorney wants to quit their role. This choice is call disclaiming responsibility. The attorney needs to fill out Form LPA 005. This form shows they want to stop being your attorney. They must send it to you and the Office of the Public Guardian. It’s best to get a lawyer’s help for this, so everything is done right.
Who Can Override a Power of Attorney UK?
Revoking a Power of Attorney in the UK is a big deal, especially in family law. Both family and legal sides are key to this. They make sure the person’s needs are protected.
Relatives and Family Members
Family, like close ones, are often the first to spot trouble with the attorney. They’re allowed to raise concerns with the Office of the Public Guardian. If they notice shady money moves or bad behavior, they can step in to keep the person safe.
Solicitors and Legal Authorities
Solicitors, working with the Solicitors Regulation Authority, are important in cancelling a Power of Attorney. They offer legal help and collect proof for the case. Legal experts beyond solicitors can also step in if they see the attorney is not doing their job well.
Steps to Remove or Replace an Attorney
In the United Kingdom, special rules are in place for changing or removing an attorney. It’s important to know these rules well. They help keep everything legal and make sure everyone’s rights are protected.
Executing a Deed of Partial Revocation
One way to take an attorney off your list is by using a deed of partial revocation. This is a legal paper you must write and sign. The person doing this, called the donor, must be able to think clearly. This document says you take back the permission you gave to an attorney before.
Appointing a Replacement Attorney
After canceling the old attorney’s power, you might want a replacement attorney. This new person might need special legal papers to become the replacement attorney. Or the old papers might already say how to choose a new one. The new attorney will then carry out the work as set in the new legal papers.
Role of the Office of the Public Guardian
The Office of the Public Guardian (OPG) has an important job. They make sure Powers of Attorney work right. OPG watches over how attorneys act. And they protect what’s important for the people giving the Power of Attorney.
Investigating Misconduct
The OPG looks into reports of attorneys not doing their job. This might be abuse of money or being neglectful. OPG follows strict steps when checking these claims.
Legal Actions and Interventions
When they find bad behavior, they act. This could mean watching closer or even stopping the Power of Attorney. OPG steps in to protect the donor. They make sure the donor isn’t taken advantage of.
Cases When an Attorney Must Stop Acting
An attorney might need to stop working in some cases. Mostly, this happens when they have a problem making decisions or if their personal relationships change. When this happens, the attorney has to quickly stop their work. They do this to protect the interests of the person who got their help.
Mental Capacity Issues
If an attorney can’t make right choices because of mental issues, they have to quit. Not making decisions that could hurt the person is why. This keeps the Power of Attorney valid. It’s very important to prevent such issues for the arrangement to be trusted. It ensures the person’s well-being.
Divorce or Dissolution of Civil Partnership
Sometimes, if an attorney was the spouse or partner of the person needing help, and they split, they must stop. This is considered big according to the law. It changes the Power of Attorney’s situation. Usually, the attorney has to leave. If not, there could be problems like misusing their power or having a conflict of interest.
Legal Advice for Overriding a Power of Attorney
Getting help from a legal advice expert is very important when you’re looking to challenge or change a Power of Attorney. They focus on resolving disputes and family law issues. This ensures the person giving the power is looked after properly.
Knowing the details of the attorney act and what it means can be hard. A legal advisor can really help. They’ll check if you have a case and take you through the legal process.
Here are some important points to think about when you need legal advice:
- Talk to a lawyer who knows about power of attorney dispute resolution.
- Collect all key documents about the Power of Attorney and any proof of wrongdoing.
- Share worries about the person’s ability to make decisions or handle money.
By getting ready and working with skilled legal advice, you can handle the process of changing a Power of Attorney well and with good intent.
Difference Between Lasting and Ordinary Power of Attorney
The difference between a lasting vs. ordinary power of attorney is how long they last and what they cover. An Ordinary Power of Attorney (OPA) helps with financial affairs briefly or when someone can’t be there. It stops being valid if the donor becomes unable to make their own decisions.
A Lasting Power of Attorney (LPA) lasts longer and helps with big choices. It kicks in when the donor can’t decide about their financial affairs or healthcare decisions. This makes it different from an OPA, which is short-term.
Having an LPA is vital for managing a person’s interests for a long time. It’s a safe way to deal with both financial affairs and important healthcare decisions when a person can’t make choices on their own.
It’s key to know the difference between a lasting vs. ordinary power of attorney. This knowledge is crucial for smart planning. It protects the donor’s interests, whether for a short time or long-term.
Potential Consequences of Overriding a Power of Attorney
Overriding a power of attorney has serious results legally and personally. It can lead to legal fights about who gets to manage the donor’s affairs. This often causes arguments in the family over the new representer.
This change can drastically alter how the donor’s finances or health is managed. The new attorney might make new choices that affect the donor’s health. Knowing the law is just as important as understanding the duty that comes with it.
Override may prompt clashes between family members too. Choosing a new attorney can lead to disputes, especially if it makes someone feel left out. These fights can harm family ties and make things hard for everyone involved.
The role of the new attorney is both important and challenging. They need to address any old issues and focus on the donor’s well-being. Remember, the outcomes of overriding a power of attorney can be serious and lasting.
Conclusion
Changing or voiding a Power of Attorney is a big step. It’s crucial to know the differences between a lasting and an enduring power. Understand when it’s right to stop an agent’s duties. This ensures the donor’s wellbeing remains a top priority. Friends, legal experts, and other key people should think these points over well. Their main goal is to safeguard the donor’s rights.

Can Doctors, Care Homes, or Social Services Override a Power of Attorney?
One of the most common points of confusion in our experience is the assumption that medical professionals or social services can simply override a Lasting Power of Attorney if they disagree with an attorney’s decisions. The reality is more nuanced, and understanding where genuine authority lies can make a significant difference to how quickly a dispute is resolved.
What Authority Do Doctors and Medical Professionals Actually Hold?
Doctors and clinicians cannot override a health and welfare LPA directly, but they do hold meaningful influence. Under the Mental Capacity Act 2005, any decision made on behalf of a person who lacks capacity must be in that person’s best interests. If a treating clinician believes an attorney’s decision is not in the donor’s best interests — for example, refusing a recommended treatment — they may decline to act on the attorney’s instruction and refer the matter to the Court of Protection. In practice, most hospitals and care settings have mental capacity lead practitioners and safeguarding teams who will escalate concerns formally rather than simply comply with an attorney’s wishes.
The Role of Social Services and Care Homes
Social services have a duty under the Care Act 2014 to investigate allegations of abuse or neglect, which may include financial or personal welfare decisions made by an attorney. A care home manager who has genuine safeguarding concerns is typically expected to report those concerns to the local authority and to the Office of the Public Guardian rather than attempt to override the LPA themselves. Neither a care home nor a social worker holds the legal power to suspend or revoke an LPA — that authority rests with the Court of Protection alone.
The Court of Protection: When Override Becomes Unavoidable
The Court of Protection, established under the Mental Capacity Act 2005, is the only body with the legal authority to suspend, revoke, or place restrictions on a registered LPA without the donor’s consent. The Court of Protection can appoint a deputy to replace an attorney, cancel the LPA entirely, or make a one-off decision where the attorney and a third party are in dispute. It is worth being candid about what this involves: deputyship applications typically take six to nine months to process, involve court fees, potential legal costs, and can be emotionally exhausting for all parties involved. In our experience, families who reach this stage often wish they had built clearer safeguards into the original LPA — such as named certificate providers, named persons to notify, or specific guidance clauses limiting the attorney’s discretion in particular circumstances. These drafting choices are not bureaucratic formalities; they are the most practical protection against disputes ever reaching court. England and Wales law applies throughout this section; the position in Scotland is governed separately by the Adults with Incapacity (Scotland) Act 2000, under which the Office of the Public Guardian (Scotland) and the Sheriff Court perform broadly equivalent roles.
Common Questions About Overriding a Power of Attorney
How do I remove myself as a power of attorney in the UK?
An attorney who wishes to step down may do so by formally disclaiming their appointment. This is done by completing a deed of disclaimer and serving it on the donor (if they still have capacity), any co-attorneys, and — where the LPA is registered — the Office of the Public Guardian. Once disclaimed, you can no longer act under that power. It is generally advisable to notify all relevant third parties, such as banks, as they may continue to accept instructions until they receive formal notification. You should take legal advice before disclaiming if the donor currently lacks capacity, as stepping down without a replacement in place may leave them without anyone authorised to act on their behalf.
Can you challenge a power of attorney in the UK?
Yes. A challenge may be raised with the Office of the Public Guardian, which investigated over 4,500 safeguarding cases in 2022/23, demonstrating that concerns about attorney conduct are far from rare. The OPG can investigate complaints, issue guidance to attorneys, and apply to the Court of Protection to revoke an LPA. Where the OPG’s powers are insufficient — for instance, in urgent or complex cases — an application directly to the Court of Protection may be necessary. In our experience, a complaint to the OPG is most likely to succeed where there is documentary evidence of financial misuse or clear disregard of the donor’s known wishes; cases that rely entirely on family disagreement are harder to progress through the OPG route alone.
Can a sibling contest a power of attorney?
A sibling has no automatic legal standing to override an LPA simply because they disagree with the appointed attorney’s decisions. However, any person with a genuine concern about an attorney’s conduct — including a family member — may raise a safeguarding concern with the OPG or apply to the Court of Protection to be heard. If the sibling was named as a person to be notified when the LPA was registered, they will have already had an opportunity to raise objections before registration was completed. This is one reason why our team typically recommends naming independent and family contacts in that field during the drafting process.
What happens if two power of attorneys disagree in the UK?
Where two or more attorneys are appointed to act jointly, they must agree on every decision — a deadlock means neither can act unilaterally. Where they are appointed jointly and severally, each attorney may act independently, but conflicting decisions can cause serious practical difficulties, particularly with financial institutions. Persistent disagreement between co-attorneys may ultimately require one attorney to apply to the Court of Protection for a ruling, or for one attorney to disclaim their appointment. Careful drafting at the outset — specifying which decisions require joint agreement and which may be made severally — can significantly reduce this risk.
How much does it cost to revoke a power of attorney in the UK?
Revoking an LPA while the donor has mental capacity is relatively straightforward and can be done by the donor executing a deed of revocation, which carries no court fee. However, the donor would need to register a new LPA if they wish to appoint a replacement, which currently costs £82 per LPA in England and Wales (as of 2024), plus any professional fees for drafting. Where revocation requires a Court of Protection application — because the donor lacks capacity or the attorney is contesting the revocation — costs rise considerably. Court fees alone start at several hundred pounds, and legal representation, while not mandatory, is advisable in contested cases. The financial and emotional cost of a contested revocation is one of the strongest practical arguments for investing time in thorough, well-drafted LPA documentation from the outset.
