An advance directive records your wishes about medical treatment and, more importantly, names someone to make decisions if you cannot.
Most people intend to do this eventually. It is needed exactly when it cannot be created, which is the whole reason it exists and the reason "eventually" is the wrong plan.
What changed in 2026
- Digital registries expanded. More jurisdictions and health systems offered central storage accessible to clinicians.
- Portal upload became common. Health system patient portals increasingly accepted directive documents directly.
- Portability stayed imperfect. Documents valid in one jurisdiction were not always recognised in another.
- Emphasis shifted toward the agent. Guidance increasingly stressed naming a person over enumerating scenarios.
Two parts, and one matters more
The directive states your wishes about specific treatments — resuscitation, mechanical ventilation, artificial nutrition, and similar.
The agent appointment names a person to make decisions on your behalf. Different jurisdictions use different terms — healthcare proxy, medical power of attorney, healthcare agent.
The second is the more important, and it is the part people underweight.
No document anticipates every situation. Medicine presents circumstances nobody wrote down, and a document stating preferences for four scenarios is silent about the fifth. A person who knows your values can reason about what you would want in a situation the document never contemplated.
Which means the most valuable thing you can do is name the right person and talk to them properly.
Talk to the person
Naming someone without telling them is common and unhelpful.
The conversation matters more than the document, because what the agent needs is not a list of rules but an understanding of what matters to you. What quality of life means, what you would accept in exchange for what chance, what you would find intolerable.
That conversation is uncomfortable and it is the thing that equips someone to decide well under pressure. A person who has had it can act with confidence; one who has not is guessing while distressed.
Choose someone who can be reached, who can act decisively, and who will follow your wishes rather than substituting their own. Geographic proximity matters less than availability and temperament. The person closest to you emotionally is not always the person best able to make a hard decision in a hospital corridor.
Name an alternate. The primary may be unavailable or, in a shared accident, incapacitated themselves.
Distribution

Alongside other essential papers |
A directive in a drawer at home is not available in an emergency department at 3am. Distribution is what makes it operative — see document vault for keeping the copy findable.
Carry an indication that one exists — a card in your wallet naming your agent and where the document is held.
Requirements vary
Formalities differ by jurisdiction: witnessing requirements, notarisation, who may serve as a witness, and whether particular forms are required.
A document that does not meet local requirements may not be honoured, which is why using a jurisdiction-appropriate form matters. Many health systems and public bodies provide free compliant forms.
Portability across jurisdictions is imperfect. If you divide time between places, having a valid document in each is worth the effort.
Review periodically. Wishes change, relationships change, and a directive naming someone you have lost contact with is worse than none.
Common mistakes
- Directive without a named agent. No one to handle the unforeseen.
- Not telling the agent. Appointed by surprise, unprepared.
- Never having the conversation. The document cannot convey values.
- Only a copy at home. Unavailable when needed.
- No alternate agent. Single point of failure.
- Wrong jurisdiction's form. May not be honoured.
- Never reviewing it. Goes stale.
FAQ
Do I need a solicitor?
Not necessarily — many jurisdictions provide free compliant forms and self-completion is common. Professional advice is worthwhile for complex family situations or where it interacts with other estate documents.
What if my family disagrees with my agent?
A properly executed appointment gives the agent authority. Family disagreement is easier to manage if you told everyone your wishes in advance rather than leaving the agent to defend a decision alone.
Is this the same as a do-not-resuscitate order?
No. That is a medical order signed by a clinician and effective immediately. An advance directive expresses wishes that guide decisions if you become unable to communicate them.
How often should I review it?
Every few years, and after any significant health event, relationship change, or move to another jurisdiction.
