Can Power of Attorney Override a Will? UK Law Explained

This is one of the most commonly asked legal questions in England and Wales — and the answer matters enormously for estate planning and family peace of mind.

The short answer: No. A Power of Attorney cannot override a will. An attorney acting under a Lasting Power of Attorney (LPA) has no legal power to change, revoke, or override the donor's will.

But the relationship between LPAs and wills is more nuanced than that simple answer suggests. This guide explains everything you need to know.

Why an Attorney Cannot Change a Will

The Legal Position

Under the Mental Capacity Act 2005, an attorney appointed under an LPA has a duty to act in the best interests of the donor. Their powers are limited to what the LPA document authorises.

A will is a deeply personal document. It reflects the donor's wishes about what happens to their estate after death. The law is clear: only the person who made the will (the testator) can change it — and only while they have the mental capacity to do so.

An attorney's powers under an LPA relate to decisions during the donor's lifetime. They have no authority over what happens after the donor dies.

What the Law Says

The key legal principles:

An attorney cannot make or change a will on behalf of the donor
An attorney cannot destroy a will on behalf of the donor
An attorney cannot instruct a solicitor to draft a new will for the donor
An attorney's powers end when the donor dies — at that point, the will takes over

The Important Nuances

While an attorney cannot directly override a will, there are situations where their actions during the donor's lifetime can indirectly affect what is left in the estate.

1. Managing Assets That Are Mentioned in the Will

A Property and Financial Affairs attorney can manage the donor's assets. This means they may:

Sell property that was intended to be left to someone in the will
Spend savings on the donor's care that were earmarked for beneficiaries
Close investments or accounts mentioned in the will

This does not "override" the will, but it can mean that assets mentioned in the will no longer exist by the time the donor dies. This is known as ademption — when a gift in a will fails because the asset no longer exists.

Example: A will says "I leave my house at 10 Oak Street to my daughter." If the attorney sells that house to fund care home fees, the daughter receives nothing from that specific gift — not because the will was overridden, but because the asset is gone.

2. Making Gifts

Attorneys have very limited powers to make gifts. Under the Mental Capacity Act, an attorney can:

Make gifts of reasonable value on customary occasions (birthdays, Christmas)
Make donations to charities the donor previously supported

They cannot make large gifts that would significantly reduce the estate — unless they get approval from the Court of Protection.

3. The Court of Protection and Statutory Wills

There is one exception to the rule that an attorney cannot change a will. The Court of Protection can authorise what is called a statutory will.

A statutory will is a will made by the court on behalf of someone who lacks mental capacity. This might happen when:

The donor's circumstances have changed significantly since they made their will
The existing will is very old and does not reflect current wishes
There are concerns the existing will does not properly provide for dependants
The donor never made a will at all

A statutory will application must be made to the Court of Protection. An attorney, family member, or other interested party can apply — but the court decides, not the attorney.

LPA vs Will: Understanding the Difference

Many people confuse these two documents. Here is a clear breakdown:

Feature	Lasting Power of Attorney	Will

When it takes effect	During your lifetime	After your death
What it covers	Decisions about finances, property, health, and welfare	Distribution of your estate and assets
Who it appoints	Attorneys (to make decisions for you)	Executors (to carry out your wishes)
Can be changed?	Can be revoked while you have capacity	Can be updated while you have capacity
What happens at death?	LPA ceases to have effect	Will comes into force

The key insight: An LPA and a will work in sequence. The LPA protects you during life; the will protects your wishes after death. You need both.

How an Attorney Should Handle Will-Related Matters

If you are acting as an attorney under an LPA, here is what you should know:

Do Not Touch the Will

Do not attempt to read, change, or destroy the donor's will
If you know where the will is kept, ensure it is stored safely
Do not move the will without good reason

Be Careful with Asset Management

Keep records of all financial decisions and transactions
Be aware of which assets are mentioned in the will
Only sell property or spend savings when it is genuinely in the donor's best interests
Document your reasoning for significant financial decisions

If You Think the Will Needs Changing

You cannot change it yourself
You can apply to the Court of Protection for a statutory will
Get legal advice before making any application
The court will consider what the donor would have wanted

Gifts and the Estate

Only make gifts within the limits allowed by law
Do not distribute estate assets while the donor is alive (unless the court approves)
Remember that your duty is to the donor, not to the beneficiaries of the will

Why You Need Both an LPA and a Will

Many people have one but not the other. This leaves dangerous gaps:

If You Have a Will but No LPA

After death: your estate is distributed according to your wishes. Good.
During life: if you lose capacity, nobody can manage your finances or make medical decisions. Your family must apply for an expensive deputyship. Bad.

If You Have an LPA but No Will

During life: your attorneys can act on your behalf. Good.
After death: your estate is distributed according to intestacy rules — not your wishes. Your partner, children, or other loved ones may not receive what you intended. Bad.

If You Have Both

During life: protected by your LPA.
After death: protected by your will.
This is the right answer.

Frequently Asked Questions

Can a Power of Attorney override a will after the person dies?

No. A Power of Attorney ceases to have any legal effect the moment the donor dies. After death, the will (and the appointed executors) takes over. The attorney has no further authority.

Can an attorney sell property that is left to someone in a will?

Yes, if it is in the donor's best interests during their lifetime. For example, selling a house to fund care home fees is legitimate, even if the house was left to someone in the will. The gift in the will would then fail (ademption).

Can an attorney make large gifts to reduce the estate?

No. Attorneys can only make gifts of reasonable value on customary occasions (birthdays, Christmas) or to charities the donor previously supported. Large gifts require approval from the Court of Protection.

What is a statutory will?

A statutory will is made by the Court of Protection on behalf of someone who lacks mental capacity. It replaces or creates a will when the person cannot do so themselves. Only the court can authorise this — an attorney cannot do it alone.

Should I tell my attorney what is in my will?

This is a personal choice. Some people share this information so the attorney can make informed decisions about asset management. Others prefer to keep their will private. There is no legal requirement either way.

What happens if an attorney acts against the interests of the will beneficiaries?

An attorney's duty is to the donor, not to the will beneficiaries. If the attorney is acting in the donor's best interests, the fact that this reduces the estate is not a breach of duty. However, if an attorney is acting dishonestly or not in the donor's interests, the OPG can investigate.

The Bottom Line

A Power of Attorney and a will serve different purposes at different times. An attorney cannot override your will — but their actions managing your affairs during your lifetime can affect what is left in your estate.

The solution: have both documents in place, and make sure your attorney understands their responsibilities.
