Can a Power of Attorney Change a Will? Many people get this wrong when dealing with inheritance rules: just because someone has lasting power of attorney does not mean they can change or write a will for another person. When a family member becomes unwell or loses capacity, relatives often think the appointed attorney – already handling bills, selling homes, making money choices – must also be allowed to revise the will. That assumption leads straight into legal trouble. Managing finances and touching a will are completely different things under the law.
This difference – though it looks small – can lead to serious outcomes. Knowing precisely when an agent’s authority starts and stops matters greatly, not just to agents, but also to heirs, relatives, wherever there’s concern about a will being unfairly shaped.
Read our complete guide on contesting a will for lack of capacity.

What a Lasting Power of Attorney Actually Authorises
A Lasting Power of Attorney (LPA) is a legal document registered with the Office of the Public Guardian that allows a nominated person — the attorney — to make decisions on behalf of another person, known as the donor, should the donor lose mental capacity.
There are two types of LPA in England and Wales:
- Property and Financial Affairs LPA — covers decisions about money, bank accounts, investments, bills, and property.
- Health and Welfare LPA — covers decisions about medical treatment, care arrangements, and day-to-day welfare.
Most of what an attorney handles comes down to daily money choices. They handle payments, track accounts, and move assets around when needed. Should things shift toward bigger decisions, selling property stays on the table if required. Changing a will? That step remains off limits, no matter the situation. Even with full trust, rewriting last wishes sits completely outside their role.
Clear rules apply here. Premier Solicitors states that someone named under a lasting power of attorney cannot alter or draft a will for another person. A will carries deep personal meaning. Shaped by beliefs, bonds, and choices, it stays firmly in the hands of the individual who made it. Only they hold the final say over what happens to their assets after death.
Right there, deep inside the Wills Act 1837, lies this idea – repeated again through court rulings over time. Not while things end, but long before that, an attorney steps in to handle matters as life goes on. Only once breath stops does a will start to matter. One works in today’s world, the other waits quietly for when days run out.
Why the Law Draws This Line
It wasn’t just made up out of nowhere. Letting lawyers change wills opens too much chance for misuse. Picture someone trained in law, due to gain something from a will – maybe listed now, or cut before – they’d have reason enough, plus the ability, to adjust things quietly in their favour.
One moment of weakness shouldn’t invite hidden control. The Law Society points out that misusing an LPA counts as financial abuse against those who can’t easily defend themselves. Should attorneys gain the power to alter wills, a trust might collapse when it matters most. In illness or decline, family bonds face strain – just when they’re needed strongest.
A layer of protection shows up when decisions about someone who is unable to consent are reviewed by a judge. When adjustments to their wishes come up, a court steps in so fairness stays in view, holding what matters most to that individual as the top priority.
When Can a Will Be Changed for Someone Who Lacks Capacity?
There is one route by which the will of a person who lacks mental capacity can lawfully be altered: an application to the Court of Protection for a Statutory Will.
A person unable to make their own decisions about a will might still have one created through legal channels. When someone lacks mental ability, the Court of Protection steps in under rules from 2005. This process allows changes that otherwise would not be allowed. Only this route ensures such actions are lawful. Without it, altering wishes after loss of awareness isn’t permitted.
The Court of Protection may review a Statutory Will request under certain conditions.
- Without a will, the person who gave hasn’t set clear wishes. The default inheritance path might hand things out in ways they wouldn’t have wanted.
- Out of step with today’s reality, the donor’s current will still name people who are gone. Family shifts happened, yet those changes never made it into the document. What once fit now misses the mark completely.
- A shift in how taxes are handled now means the current will adds extra expense for the estate.
- Life changes like a wedding, splitting up, or a baby arriving may matter to someone who gives. These moments often shift what they’d want remembered. Their choices could need updating because of it.
Most importantly, the court looks at what is truly best for the individual, judged from an outside viewpoint, following section 4 of the Mental Capacity Act 2005. Looking back at how the person has felt before, plus how they feel now, shapes part of that judgment. Their beliefs and personal outlook matter just as much when decisions are weighed up.
Input comes not only from close relatives but also from those who provide day-to-day support. Other details tied to the situation might influence the outcome, too. In some cases, the Official Solicitor steps in to represent someone unable to manage legal proceedings alone.
The Application Process
According to GOV.UK’s statutory will guidance, an applicant must:
- Complete the relevant Court of Protection forms, including an assessment of the donor’s mental capacity (form COP3), which must be signed by a medical professional.
- Submit supporting documents including any existing will, details of proposed executors, and a copy of any registered LPA.
- Notify all parties with a potential interest in the estate.
- Attend a hearing if the court considers one necessary.
- Sign and witness the approved will before returning it to the court to be sealed.
Most people expect things to move fast. Still, Clarke Willmott says straightforward cases often stretch from four to six months – timing hinges on how busy the courts happen to be. When someone’s time is limited due to health, urgent requests can go through. Even then, strict rules apply before approval. Slowing down even further, a flat charge of £365 lands on every applicant once paperwork hits the courthouse desk.
What Happens When an Attorney Abuses Their Position?
Just because someone handles money doesn’t mean they can’t twist things unfairly. Even if lawyers aren’t allowed to change wills, some still find ways around it – like giving away big chunks of cash without permission, shifting property into their own pockets, or draining accounts meant for others down the line.
Warning signs that an attorney may be misusing their position include:
- Unusual or disproportionate gifts to themselves or others, inconsistent with the donor’s past behaviour.
- Unexplained transfers of property or significant sums.
- The donor’s bills going unpaid whilst funds are diverted elsewhere.
- A reluctance to provide accounts or documentation to the Office of the Public Guardian.
When lawyers take money without permission, says Steene Law Solicitors, the Public Guardian might ask the court to step in. Removal could follow. Police involvement is possible, too. Such misuse often breaks laws like the Fraud Act 2006. In harsher situations, it falls under the Theft Act 1968 instead.
Where such misconduct has affected the distribution of a deceased person’s estate, family members and other interested parties may have grounds to challenge the will or bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975. An experienced contentious probate solicitor can advise on the most appropriate legal route depending on the specific facts.
Practical Steps If You Are Concerned
Should you think a solicitor behaved wrongly – like pushing to alter a will, draining an estate, or pressuring the person who made it – you can take steps. Options open to you include raising concerns with regulators, speaking to another legal professional, filing a complaint through official channels, or seeking court intervention if needed.
Someone spots misuse. That triggers a report to the Office of the Public Guardian. Oversight falls to them when it comes to deputies or attorneys acting improperly. If warnings arise, they may launch inquiries without delay. Evidence of harm opens the door to court applications. Proof leads straight to the removal of an LPA on record. Reporting happens through their designated online system – no alternatives provided.
Should disagreements arise over an attorney’shandlingofadonor’smatters, the Court of Protection could become involved. Removal requests often lead in that direction. When management choices spark conflict, court intervention sometimes follows. Decisions may shift once paperwork enters the system. Questions about authority tend to open that path. Filing happens when trust thins. Legal oversight steps in where uncertainty grows.
Startbytalkingtoalawyeraboutthe estate. If the person has passed away and you think their assets were wrongly decreased because of what an attorney did, a specialist in disputed wills might find it possible to take steps against the decision or file a complaint.
A word of caution here. Worried the will might not hold up, or that probate could go through too soon? Put a stop to it by filing a caveat at the Probate Registry. That move blocks any grant while things get looked into properly. Nothing moves forward until questions are clear.

FAQs
Can a power of attorney make gifts on behalf of the donor?
Only to a very limited extent. Under the Mental Capacity Act 2005, an attorney may make gifts on behalf of the donor on customary occasions — such as birthdays or Christmas — and to people related to or connected with the donor, provided the value of those gifts is not unreasonable relative to the size of the estate. Any gifts beyond this require the court’s authorisation. Making substantial unauthorised gifts — particularly to oneself — is a recognised form of financial abuse and can result in criminal prosecution.
What if the donor still has some capacity? Can they change their will themselves?
Capacity is decision-specific under UK law. A person may retain the ability to make a will — known as testamentary capacity — even if they lack the capacity to manage their finances. The relevant test for testamentary capacity is set out in the landmark case of Banks v Goodfellow (1870), which requires the testator to understand the nature of making a will, the extent of the estate they are disposing of, and the claims of those who might reasonably expect to benefit. If these conditions are met, a person can make or update their will despite having an LPA in place.
Can a will be challenged after the donor dies if an attorney misused their position?
Yes. Where there is evidence that an attorney exploited their position of trust — for example, by exerting undue influence over the donor or depleting the estate before death — a will or the administration of an estate can be challenged through contentious probate proceedings. Depending on the circumstances, a claim may also be available under the Inheritance Act 1975. Early legal advice is essential, as strict time limits apply.
Conclusion
Just because someone holds a lasting power of attorney doesn’t mean they can tweak the will. That line often gets blurred, yet it matters deeply in England’s inheritance rules. Trust alone won’t grant that kind of control – no matter how wide the legal document seems. Changes to last wishes sit beyond even broad powers given by an LPA. Authority rests solely with the Court of Protection when a statutory will request comes through. Decisions like these never fall into private hands.
If worries arise over how a lawyer managed a family member’s matters, getting expert legal guidance quickly makes sense. When actions might have harmed an estate, waiting can weaken your position. Rights exist under the rules, yet they matter most when someone knows how to act on them.
Backed by three decades of handling will challenges, Contest a Will Today focuses solely on inheritance conflicts throughout England and Wales. When suspicion arises that someone used the power of attorney improperly to alter estate outcomes, reaching out could clarify next steps.
