Living Will Wales — What It's Actually Called and How to Make One

"Living Will" Isn't the Legal Term

If you search for "living will Wales," you're looking for the right thing — a legally binding document that lets you refuse specific medical treatments in advance — but using outdated terminology that could trip you up when dealing with healthcare professionals.

The correct legal name under the Mental Capacity Act 2005 is an Advance Decision to Refuse Treatment (ADRT). The term "living will" predates the Act and has no official standing. Clinicians in NHS Wales are trained on ADRTs, not living wills, and using the older term with a GP receptionist or hospital team can create unnecessary confusion about what you're asking for.

This matters beyond semantics. A document titled "My Living Will" that doesn't meet the ADRT requirements under the Mental Capacity Act 2005 may not be treated as legally binding — even if the content is perfectly clear.

What Makes an ADRT Legally Binding in Wales

The Mental Capacity Act 2005 applies across England and Wales, so the legal requirements are the same in Cardiff as they are in London. A valid ADRT must meet these criteria:

1. You have mental capacity on the day you create it — you understand what you're deciding, why it matters, and the consequences of refusing treatment.
2. It names specific treatments you refuse — not vague phrases like "no heroic measures" or "no life support if my quality of life is gone." Clinicians cannot interpret subjective language under emergency conditions.
3. It describes the circumstances under which those refusals apply — for example, "if I develop advanced, irreversible dementia" or "if I am in a permanent vegetative state."
4. If it covers life-sustaining treatment, it must include the written statement: "even if my life is at risk or may be shortened as a result." It must also be signed, dated, and witnessed by an independent adult who is not your spouse, partner, or relative.

An ADRT that meets these criteria is legally binding on every clinician in Wales. A doctor who ignores a valid, applicable ADRT faces civil liability and potential criminal charges for battery.

How It Differs From an Advance Statement

Wales uses both ADRTs and Advance Statements, and confusing the two is a common mistake. The NHS Wales All Wales Advance Care Planning forms include both types.

An Advance Statement (sometimes called a "Statement of Wishes and Preferences") records your broader care preferences — things like where you'd prefer to die, whether you want religious rites, your views on organ donation, comfort measures you value. Advance Statements are advisory, not legally binding. Clinicians must consider them when making best-interests decisions, but they're not obligated to follow them.

An ADRT is legally binding. It doesn't express preferences — it refuses specific treatments outright.

If you want your wishes to carry legal force, you need an ADRT. An Advance Statement is a useful companion document, but on its own, it cannot stop a treatment you don't want.

Creating an ADRT in Wales: The Practical Steps

You don't need a solicitor. You don't need to pay anything. The legal requirements are about content and execution, not professional involvement:

1. Download the All Wales ADRT form from NHS Wales's Future Care Planning page, or draft your own document — any written format is acceptable as long as it meets the statutory requirements.
2. List each treatment you refuse and the circumstances in clinical language. Our guide includes wording templates for the most common refusals: CPR, invasive mechanical ventilation, clinically assisted nutrition and hydration, dialysis, and IV antibiotics.
3. Include the life-sustaining treatment declaration if any of your refusals cover treatments that could keep you alive.
4. Sign and date the document in the presence of an independent witness (over 18, not your spouse/partner/relative).
5. Deliver the original to your GP surgery and ask the practice manager to scan it to the Welsh Care Records Service. This activates the "Future Care Plan discussed" flag on the Welsh Clinical Portal, so hospital and ambulance teams can find it.
6. Place a copy in a Green Bottle in your fridge and stick the green sticker on your front door — the Welsh Ambulance Service is trained to check for this.

Where "Living Will" Templates Go Wrong

Free living will templates found online — especially those from non-UK sources — frequently fail the specificity test. A template that says "I do not wish to receive treatment that merely prolongs the process of dying" sounds reasonable but gives clinicians nothing actionable. What counts as "merely prolonging"? A course of antibiotics? A blood transfusion? The phrase is subjective, and under time pressure, doctors will err on the side of treatment.

The templates that work are the ones that name each treatment individually and tie the refusal to identifiable medical scenarios.

Our Wales ADRT planning guide includes pre-drafted refusal clauses for seven common treatment categories, cross-referenced to Welsh clinical terminology so your GP and hospital teams recognise exactly what you mean.
