Advance Directive vs Power of Attorney Scotland: Which Do You Need?
They Solve Different Problems — But Work Best Together
An advance directive and a welfare power of attorney are the two main tools for healthcare planning in Scotland, and they are commonly confused. They serve fundamentally different purposes, operate under different legal frameworks, and activate in different ways. Most families navigating end-of-life planning need both.
Here is how each one works and why relying on just one leaves gaps.
What an Advance Directive Does
An advance directive (sometimes called a living will) lets you refuse specific medical treatments in advance, in case you lose the capacity to communicate those decisions later. It is a prospective exercise of your common-law right to refuse treatment.
Key characteristics:
- Legal basis: Scots common law, reinforced by Section 1 of the Adults with Incapacity (Scotland) Act 2000
- What it covers: Treatment refusals only — you can refuse CPR, ventilation, feeding tubes, and other interventions, but you cannot use an advance directive to request treatments
- When it activates: When you lose capacity and the clinical scenario you described in the document actually arises
- Registration: None required — there is no government body that registers advance directives in Scotland
- Cost: Free to create (no solicitor required)
What a Welfare Power of Attorney Does
A welfare power of attorney (WPA) appoints someone — your "attorney" — to make healthcare and personal welfare decisions on your behalf if you lose capacity. Unlike an advance directive, which only covers treatment refusals, a welfare attorney can make active decisions: consenting to surgery, choosing a care home, making dietary decisions, and managing day-to-day personal welfare choices.
Key characteristics:
- Legal basis: Statutory — the Adults with Incapacity (Scotland) Act 2000
- What it covers: All healthcare and personal welfare decisions, not limited to treatment refusals
- When it activates: Only after a medical practitioner formally certifies that you lack capacity for the specific decision in question
- Registration: Must be registered with the Office of the Public Guardian (OPG) Scotland in Falkirk before it has any legal effect
- Cost: £99 OPG registration fee plus solicitor fees. Standard estate-planning fees range from £500 to over £1,000; complex work can cost more.

The Critical Difference: Refusal vs. Active Decision-Making
An advance directive says: "Do not do X to me." A welfare power of attorney says: "Let this person decide about X on my behalf."
You cannot use an advance directive to consent to treatment — only to refuse it. And a welfare attorney cannot simply substitute their own preferences; they must act in accordance with your known wishes. That is why the two tools complement each other.
Why You Need Both
Scenario 1: You have an advance directive but no welfare attorney. You are admitted to hospital unconscious, and your advance directive covers ventilation but not a proposed surgical procedure. There is nobody authorised to consent to the surgery on your behalf. The medical team would have to proceed under an AWI Section 47 Certificate — a statutory general authority to treat an incapable adult — which takes decision-making out of everyone's hands.
Scenario 2: You have a welfare attorney but no advance directive. Your attorney must try to determine what you would have wanted, based on conversations and whatever evidence exists. Without a written record of your specific treatment refusals, they are guessing — and doctors may push back if the attorney's decision seems inconsistent with preserving life.
With both: Your advance directive covers the specific treatments you refuse. Your welfare attorney handles everything else — consenting to treatments the directive does not address, choosing care settings, managing the practical details. The attorney can also point doctors to the advance directive as evidence of your documented wishes, which strengthens both documents.
The OPG Backlog Makes This Urgent
Here is the practical problem: registering a welfare POA with the OPG Scotland currently takes approximately 46 business days for electronic submissions (EPOAR) and roughly 75 business days for postal submissions. If capacity is declining, that gap is dangerous.
An advance directive has no registration requirement. When it was made with capacity, was informed and free from coercion, clearly applies to the clinical situation, and is properly signed and witnessed, it can take effect without registration. Standard practice among Scottish solicitors is to draft the advance directive and the welfare POA simultaneously, so the directive provides immediate protection while the POA works its way through the OPG queue.
Can a Welfare Attorney Override Your Advance Directive?
No. Under the AWI Act's guiding principles, a welfare attorney must give effect to your "will and preferences." An advance directive is the most authoritative written record of those preferences. If your advance directive clearly refuses a specific treatment, your welfare attorney is legally obligated to respect that refusal — not override it.
The safest approach is to incorporate the advance directive's terms directly into the welfare POA document, or to include a clause in the POA instructing the attorney to enforce the separately executed advance directive. This prevents clinical gridlock in an emergency.
For a step-by-step approach to drafting both documents so they work together seamlessly — including the cross-referencing clauses, the OPG registration process, and the NHS KIS upload — the Scotland Advance Directive Planning Kit covers the full workflow from drafting through clinical integration.
