How to Revoke or Cancel an Advance Directive in Scotland

Changed your mind about what's in your advance directive? Good news: revoking or modifying the document in Scotland is simpler than creating it. The same common-law principles that make advance directives valid also make them straightforward to undo.

But "straightforward" doesn't mean "informal." A sloppy revocation can leave conflicting documents in your medical records, creating exactly the kind of clinical confusion the directive was meant to prevent.

Formal Revocation vs Disapplication

Scots common law recognises two distinct ways to change course:

Formal revocation permanently cancels the entire advance directive. It requires a written statement — signed and dated, ideally witnessed — that explicitly declares the original directive has no further legal effect. A clear form of words: "I hereby revoke the Advance Directive executed by me on [date] and declare it to be of no legal effect."

Disapplication is immediate and informal. It happens in the moment when you're still capable: you verbally tell your medical team that you want a treatment you previously refused, or you behave in a way that clearly contradicts the written directive. Clinicians must honour your contemporaneous, expressed wishes over a previously written document — the most recent statement of a capable adult always takes priority.

The difference matters because disapplication doesn't cancel the directive permanently. If you lose capacity again after the disapplication, the written directive could potentially be referred to again. Formal written revocation eliminates any future ambiguity.

Step-by-Step Revocation Process

Step 1: Draft the written revocation. Keep it brief and unambiguous. Name the original directive by its date of execution. State that you revoke it entirely. Sign, date, and have an independent witness co-sign.

Step 2: Deliver to your GP. Bring a physical copy to your GP surgery and request that the scanned directive in your electronic patient record is marked as "deactivated." Ask the GP to remove or update the clinical alert on your Key Information Summary (KIS). This step is critical — if the old directive remains flagged on your KIS, paramedics and A&E staff may follow outdated instructions in an emergency.

Step 3: Notify your welfare attorney. If you've appointed a welfare attorney under a power of attorney, provide them with a copy of the revocation. An attorney who presents an obsolete directive during a medical crisis could inadvertently block treatment you now want.

Step 4: Notify any other holders. Retrieve old physical copies from anyone you distributed them to — family members, hospital consultants, solicitors. Destroy the obsolete originals.

Step 5: Inform specialist teams. If you have an ongoing relationship with a hospital consultant or palliative care team, notify them directly. They may have filed the directive separately from your GP records.

Partial Updates Without Full Revocation

You don't have to revoke the entire directive to change one clause. A written amendment can modify specific treatment refusals while leaving the rest intact. The amendment should reference the original directive by date, identify the specific clause being changed, state the new instruction, and be signed and witnessed with the same formality as the original.

Deliver the amendment to the same list of people who hold the original: GP, welfare attorney, family members, hospital teams. Ask your GP to update the KIS to reflect the change.

One caution: multiple amendments stacked on top of an original directive create complexity. If you're changing more than one or two clauses, drafting a fresh directive and formally revoking the old one is cleaner and less prone to clinical misinterpretation.

How Long Does an Advance Directive Remain Valid?

Scotland doesn't impose an expiry date on advance directives. A directive signed twenty years ago is technically still valid — provided there's no evidence you changed your mind in the interim and the clinical scenarios it describes still match your current medical situation.

That said, a very old directive faces practical challenges. Clinicians may question whether your views have evolved, especially if your health status has changed significantly since the directive was written. A directive drafted before a major diagnosis (cancer, dementia, stroke) may not address the clinical realities you now face.

Best practice is to review your directive every two to three years, or immediately after any major health event, and re-sign it with a fresh date and witness signature. Re-signing signals to clinicians that the document reflects your current thinking, not a historical snapshot.

Our Scotland Advance Directive toolkit includes revocation templates, amendment forms, and a GP notification letter — everything needed to cleanly update or cancel your existing documents.
