Can An Advance Care Directive Be Challenged?
An Advance Care Directive is designed to record your healthcare wishes for the future.
Many people create one because they want their preferences respected if they can no longer make or communicate decisions themselves.
But families sometimes wonder what happens if somebody disagrees with the document.
Can an Advance Care Directive be challenged?
The short answer is yes.
In some situations, concerns may be raised about an Advance Care Directive.
However, disagreement alone does not automatically make the document invalid.
Healthcare providers, substitute decision-makers and legal authorities will usually focus on whether the directive is valid, applicable and reflective of the person’s wishes.
This article explains why challenges may occur and what families should understand.
Short Answer
Yes, an Advance Care Directive can be challenged.
However, a challenge does not automatically mean the document will be ignored.
Questions are usually focused on issues such as validity, decision-making capacity, unclear wording, conflicting documents or whether the directive applies to the medical situation.
Simply disagreeing with the person’s wishes is generally not enough on its own.
Why Would Someone Challenge An Advance Care Directive?
Most challenges happen because somebody believes there is a problem with the document.
For example, a family member may believe the person’s wishes changed after the document was created.
Others may believe the directive is unclear or does not apply to the current medical circumstances.
In some cases, people simply misunderstand what the document says.
Healthcare decisions can be emotional, especially during a medical crisis.
This can sometimes lead to disagreements.
Common Reasons A Directive May Be Challenged
- Questions about decision-making capacity
- Concerns about pressure or influence
- Unclear wording
- Conflicting versions of the document
- Claims that wishes changed later
- Disputes about whether the directive applies to the situation
- Questions about legal requirements
Not every concern will lead to a formal dispute.
Sometimes a simple discussion can resolve misunderstandings.
Can Family Members Challenge A Directive?
Family members can raise concerns.
They may question whether the document reflects the person’s wishes.
They may believe circumstances have changed.
However, family members cannot automatically overturn an Advance Care Directive simply because they disagree with it.
The focus is usually on what the person wanted, not what relatives prefer.
This is one reason advance care planning conversations are so important.
When families understand the person’s wishes ahead of time, disputes may be less likely.
What Happens If Concerns Are Raised?
If family members raise concerns, healthcare providers will usually consider the reasons behind those concerns.
This may involve reviewing the Advance Care Directive, discussing previous conversations, checking for newer documents and considering whether there is evidence that the person’s wishes changed after the directive was created.
In more complex situations, legal advice, ethics teams, tribunals or courts may become involved, depending on the circumstances and the laws that apply.
What matters most is whether there is credible evidence that the directive is invalid, unclear or no longer reflects the person’s wishes.
Disagreement alone is usually not enough to overturn a valid Advance Care Directive.
Does A Challenge Mean The Directive Is Invalid?
Not necessarily.
Raising concerns about a document is different from proving that the document is invalid.
Healthcare providers and decision-makers will usually consider the reasons for the challenge and the available evidence before deciding how the directive should be applied.
What If Someone Claims The Person Changed Their Mind?
This is one of the more common situations.
A relative may say that the person expressed different wishes after completing the directive.
If concerns are raised, healthcare providers may need to consider available information.
This could include conversations, newer documents or evidence about the person’s more recent wishes.
The circumstances will depend on the individual situation and applicable laws.
What If There Are Multiple Versions?
Multiple versions can create confusion.
One family member may have an older copy.
Another may have a newer version.
A healthcare provider may have something different again.
This is why it is important to replace outdated copies whenever possible and ensure key people have the most current version.
Keeping multiple versions in circulation may increase the risk of disputes.
Can A Directive Be Challenged Because It Is Old?
Age alone does not automatically make a directive invalid.
Many older directives continue to provide valuable guidance.
However, if the document was completed many years ago and there is evidence that circumstances changed significantly, questions may arise about whether it still reflects the person’s wishes.
Regular reviews can help reduce uncertainty.
What If The Wording Is Unclear?
Unclear wording can create challenges.
Broad phrases such as “no heroic measures” may be interpreted differently by different people.
Doctors, substitute decision-makers and family members may all have different views about what those words mean.
In these situations, additional discussion may be required to better understand the person’s intentions.
This is why clear language is often recommended.
Can A Challenge Delay Decisions?
Sometimes yes.
If concerns are raised about a directive, healthcare providers may need additional information before proceeding with certain decisions.
They may need to review documents, speak with substitute decision-makers or clarify the person’s wishes.
This does not mean treatment automatically stops.
It simply means additional steps may be required to understand the situation.
What Role Does A Substitute Decision-Maker Play?
A substitute decision-maker may help explain the person’s wishes when questions arise.
They may provide context about previous conversations, values and healthcare preferences.
Their role is generally to help represent what the person would have wanted.
This can be particularly important if a directive is unclear or challenged.
How Can You Reduce The Risk Of Challenges?
No document can completely prevent disputes.
However, several practical steps may help reduce the risk:
- Use clear wording
- Review documents regularly
- Tell family about your wishes
- Choose an appropriate decision-maker
- Replace outdated versions
- Keep documents accessible
- Discuss your wishes with healthcare providers
These steps can help create greater clarity for everyone involved.
Common Mistakes To Avoid
Never Discussing Your Wishes
Family members may be surprised by decisions they have never heard discussed.
Using Vague Language
Unclear instructions can create confusion and disagreement.
Keeping Multiple Versions
Old copies may create uncertainty about which document is current.
Failing To Review Documents
Regular reviews help ensure your directive still reflects your wishes.
Choosing The Wrong Decision-Maker
Your substitute decision-maker should understand and respect your preferences.
Real-Life Example
Margaret completed an Advance Care Directive after discussing her wishes with her GP and family.
Several years later, she became seriously ill.
One family member believed Margaret would have changed her mind about certain treatments.
Another family member pointed to the directive and previous conversations.
The healthcare team reviewed the document and spoke with Margaret’s appointed decision-maker.
After considering the available information, they were able to better understand Margaret’s wishes.
The disagreement raised questions, but it did not automatically invalidate the directive.
