Advance Statement vs Advance Decision in Wales — Which One Is Legally Binding?

Two Documents, Completely Different Legal Weight

Wales's advance care planning framework uses two distinct instruments, and confusing them is one of the most common mistakes in end-of-life planning. The names sound similar. The All Wales forms look similar. But their legal standing under the Mental Capacity Act 2005 is entirely different.

An Advance Decision to Refuse Treatment (ADRT) is legally binding. When a valid ADRT applies to the clinical situation, the doctor must follow it — even if they believe treatment would be in your best interests. Ignoring a valid ADRT exposes the clinician to civil liability and potential criminal charges for battery.

An Advance Statement (sometimes called a "Statement of Wishes and Preferences") is advisory. Clinicians must take it into account when making best-interests decisions on your behalf, but they are not obligated to follow it. If a clinical team concludes that your stated preferences conflict with your best interests, the preferences can be overridden.

What Each Document Covers

Advance Decision (ADRT):

• Specific treatment refusals — named treatments (CPR, ventilation, artificial feeding, dialysis) refused under named circumstances (advanced dementia, permanent vegetative state, end-stage terminal illness)
• Applies only to refusals — you cannot use an ADRT to demand a specific treatment
• Must meet statutory requirements: written, signed, dated, witnessed (if refusing life-sustaining treatment), with the life-sustaining declaration

Advance Statement:

• Broader care preferences — where you'd prefer to die (home, hospice, hospital), religious or spiritual wishes, comfort measures, music or companions you'd want present, dietary preferences, views on organ donation
• Values and beliefs that should guide decisions in situations the ADRT doesn't cover
• No formal execution requirements — can be handwritten, typed, or verbal (though written is strongly preferred)

In Welsh practice, the NHS Wales Future Care Planning forms include both types. The All Wales ADRT form handles treatment refusals. Regional tools like Powys Teaching Health Board's "My Life, My Wishes" booklet focus more on the statement side — broader wishes about care settings, daily routines, and personal values.

Why You Probably Need Both

An ADRT is sharp and narrow — it says "do not do X if Y happens." It doesn't help clinicians navigate the hundreds of smaller decisions that arise during end-of-life care: what kind of pain relief you'd prefer, whether you want to be moved to a hospice, whether your family should be in the room, whether you have cultural or religious requirements around last rites.

An Advance Statement fills those gaps. It gives the clinical team a picture of who you are and what matters to you, so their best-interests decisions reflect your values rather than institutional defaults.

Here's a practical example. Your ADRT refuses CPR and invasive ventilation if you have end-stage dementia. Your Advance Statement says you want to die at home with your family present, you'd like Welsh hymns playing, and you want your minister contacted. The ADRT stops the ventilator. The Advance Statement shapes the care around that decision.

Without the statement, the clinical team's best-interests assessment defaults to clinical convenience — hospital care, standard visiting hours, generic palliative protocols. With it, they have grounds to honour your personal wishes even when those wishes aren't legally binding.

The Priority Rules

If your ADRT and Advance Statement contradict each other, the ADRT wins for treatment decisions. If your ADRT says "no artificial feeding" and your Advance Statement says "please keep me comfortable and nourished," the ADRT's specific refusal of artificial feeding takes legal priority. The statement's mention of nourishment would apply to oral feeding (food and drink by mouth), not to a PEG tube.

If a Health and Welfare LPA is also in the picture, the chronological order matters. An ADRT made after the LPA overrides the attorney on those specific treatments. An LPA made after the ADRT overrides it if the attorney has authority over life-sustaining treatment — unless the ADRT is explicitly referenced in the LPA.

How to Create Both in Wales

For the ADRT: Use the All Wales ADRT form (downloadable from NHS Wales) or draft your own document meeting the Mental Capacity Act 2005 requirements. Name specific treatments and circumstances. Sign, date, and have it witnessed if refusing life-sustaining treatment. Deliver the original to your GP for Welsh Clinical Portal registration.

For the Advance Statement: Use the All Wales ACP-A form, the Powys "My Life, My Wishes" booklet, or write your own in any format. No formal signing or witnessing is required, but dating and signing it adds credibility. Give copies to your GP, your LPA attorneys, and your family.

Our Wales ADRT planning guide includes templates for both documents, a comparison chart so you can see exactly what belongs in each, and coordination guidance to ensure they work together rather than creating clinical confusion.
