Who Can Override a Power of Attorney?

When you appoint someone to act on your behalf under a Lasting Power of Attorney, you place significant trust in that person. But what happens if concerns arise about how an attorney is managing your affairs? Can their decisions be challenged or overridden?

Understanding the safeguards surrounding Lasting Powers of Attorney (LPAs) is important for both donors and their families. While attorneys have considerable legal authority, protections exist to prevent abuse.

In this guide, we explain the role of the Court of Protection and Office of the Public Guardian in protecting vulnerable individuals, and what steps you can take if you have concerns about an attorney's conduct.

If you need tailored advice on Lasting Powers of Attorney or assistance with challenging an attorney's decisions, our experienced power of attorney solicitors are here to help.

Can a power of attorney be overridden?

A common legal question is ‘who can override a power of attorney?’ The simple answer is that whilst an LPA cannot be "overridden", there is no individual or organisation that can simply step in and take over.

A Lasting Power of Attorney can be challenged through the Court of Protection if there are concerns about the attorney’s conduct. It can also be revoked by the donor at any time, provided they still have mental capacity. In more serious situations — such as abuse, fraud, or where the attorney is not acting in the donor’s best interests — the Court of Protection has the power to cancel the LPA altogether.

Attorneys have significant authority, but that authority is subject to legal oversight and can be removed where necessary.

Who can challenge an attorney's decisions?

Several parties have legal standing to raise concerns about how an attorney is exercising their powers. If the donor still has mental capacity, they can revoke the LPA at any time by completing a deed of revocation and notifying the Office of the Public Guardian and the attorney.

Family members cannot directly override an attorney's decisions, but they can report concerns to the Office of the Public Guardian or apply to the Court of Protection if they believe the attorney is acting dishonestly, not acting in the donor's best interests, or making decisions beyond their authority.

The Office of the Public Guardian, local authorities, and NHS bodies can also investigate concerns and take action where necessary. The Court of Protection has ultimate authority to investigate complaints and remove attorneys who are failing in their duties.

What is the role of the Court of Protection?

The Court of Protection plays a central role in overseeing Lasting Powers of Attorney and protecting vulnerable individuals. It has wide-ranging powers, including the ability to investigate concerns about abuse or misconduct, remove attorneys who are not acting in the donor’s best interests, and appoint deputies where necessary. The court can also require attorneys to provide detailed accounts and evidence showing how they have managed the donor’s affairs.

Applications can be made by family members, the Office of the Public Guardian, or other interested parties. The court will consider evidence and can hold hearings to resolve disputes, particularly where there is disagreement among family members or evidence of financial abuse.

If you are considering applying to the Court of Protection, our Court of Protection solicitors can guide you through the process.

When can the Office of the Public Guardian intervene?

The Office of the Public Guardian (OPG) is a government body responsible for supervising attorneys and protecting people who lack capacity. The OPG can intervene when concerns are raised about an attorney's conduct, there is evidence of financial abuse, an attorney fails to act in accordance with the Mental Capacity Act 2005, or there are disputes between attorneys and family members.

When a concern is reported, the OPG will review the complaint, contact the attorney for explanations, and refer serious cases to the Court of Protection or police. The OPG has powers to visit the donor, inspect financial records, and in urgent cases, suspend an attorney's authority while investigations take place.

Can family members override a power of attorney?

Family members do not have automatic authority to override an attorney's decisions. However, if you are concerned about how an attorney is managing your loved one's affairs, you can speak directly to the attorney and request an explanation, report concerns to the Office of the Public Guardian, or apply to the Court of Protection for an investigation.

The fact that someone is a close relative does not give them legal authority to challenge decisions, but anyone with a genuine concern about the donor's welfare has the right to raise those concerns through appropriate channels.

How to report concerns about an attorney

If you believe an attorney is abusing their position or not acting in the donor’s best interests, act promptly. Gather relevant evidence (such as bank statements or correspondence) and report your concerns to the Office of the Public Guardian (OPG) via GOV.UK.

In urgent or serious cases — particularly where you suspect fraud or theft — seek advice from a solicitor experienced in Court of Protection matters and report criminal activity to the police. Abuse of a Lasting Power of Attorney can result in removal of the attorney, repayment orders, and even criminal prosecution.

Can doctors override a power of attorney?

In most cases, doctors cannot override a registered Health and Welfare LPA. When the donor lacks capacity, the attorney has authority to make medical decisions within the scope of the LPA, including life-sustaining treatment if expressly authorised.

In an emergency, doctors may provide immediately necessary treatment if it is not practicable to consult the attorney. Serious disputes can be referred to the Court of Protection.

Can a care home override LPA decisions?

A care home cannot override decisions made by a validly appointed attorney acting within their authority. However, care homes have safeguarding duties and can raise concerns with the local authority or the OPG if the donor may be at risk.

What if I disagree with the attorney’s decisions?

You can raise concerns directly with the attorney, seek mediation, report the matter to the OPG, or apply to the Court of Protection. It is important to distinguish between a genuine safeguarding issue and a difference of opinion.

Can social services override a power of attorney?

Social services cannot override an attorney’s legal authority, but they can investigate safeguarding concerns, refer matters to the OPG, and apply to the Court of Protection where necessary.

Does power of attorney override next of kin?

Yes. A registered Lasting Power of Attorney takes precedence over next of kin for decisions within its scope. The appointed attorney — not the next of kin — has legal authority to act.

What are the safeguards built into LPAs?

Lasting Powers of Attorney include several important safeguards to protect the donor. An LPA must be registered with the Office of the Public Guardian (OPG) before it can be used, and named individuals can be notified of the application and given the opportunity to object.

Each LPA requires a certificate provider to confirm the donor understands the document and is not under undue influence. Donors can include binding instructions and non-binding preferences, and attorneys are legally required to act in the donor’s best interests under the Mental Capacity Act 2005.

The OPG can investigate concerns and refer serious cases to the Court of Protection.

If you are considering making an LPA, our power of attorney solicitors can provide clear, practical guidance on the safeguards available.
