What is an advance decision?
An advance decision, sometimes called an advance decision to refuse treatment, lets a person say in advance which medical treatments they do not want in the future. It can apply if they later lose the ability to make or communicate decisions for themselves.
In England and Wales, a valid and applicable advance decision is legally binding. This means healthcare professionals must follow it, even if family members disagree.
Can family members override it?
Usually, no. Family members do not have the legal power to override a valid advance decision just because they think a different treatment would be better. The person’s own decision takes priority.
If the advance decision is clear, applies to the current situation, and meets the legal requirements, doctors must respect it. A relative cannot cancel it on the patient’s behalf.
When might there be a problem?
Sometimes there is disagreement about whether the advance decision is valid or relevant to the treatment being offered. For example, it may not be clear whether the person understood the consequences when they made it, or whether it covers the exact situation now.
There may also be uncertainty if the document is not properly written, signed, or witnessed where required. In those cases, the medical team may need to check the wording carefully and consider legal advice.
What if the family says the person changed their mind?
If there is evidence that the person later changed their mind, the advance decision may no longer be effective. This could happen through words or actions that clearly show a different choice.
Family members can raise this with the doctors, but they cannot simply declare the document invalid. The healthcare team will look at the evidence and decide whether the advance decision still stands.
What happens if there is a dispute?
If family members and clinicians disagree, the NHS team will usually try to discuss the issue and review the legal position. They may look at any written documents, medical notes, and details from people who knew the patient well.
If the dispute cannot be resolved, legal advice may be needed. In serious cases, the matter can go to court for a decision.
Key point for UK families
The main rule is simple: a valid advance decision usually cannot be overridden by family members. The person’s own wishes remain central, even when those wishes are hard for loved ones to accept.
If you are supporting someone who has made an advance decision, it is a good idea to keep a copy and make sure the GP and hospital know about it. This can help avoid confusion in an emergency.

Keep a signed copy of the advance decision, clear details of the treatments refused, any witness information, and a record that healthcare professionals have been told. This evidence helps prevent family members from overriding it in practice.

If there is a genuine dispute about applicability, clinicians should review the wording, circumstances, and medical situation carefully. If needed, legal advice or the Court of Protection may be sought, but relatives still do not have a general power to override it.
Concerns can be raised with the treating clinician, hospital complaints team, care home manager, patient advice services, or a solicitor. If the issue is urgent or serious, the Court of Protection may need to be involved.
