An advance directive is a legal document that spells out your healthcare wishes or names someone to make medical decisions if you can’t speak for yourself. Think of it as instructions left for people who care about you, written at a time when you can think clearly and without pressure.
The rules and names vary by state. This guide is general education, not legal advice.
Living Will
A living will describes what medical care you would or wouldn’t want in certain serious situations.
It may address things like:
- Whether you want life-sustaining treatment if there’s no reasonable chance of recovery
- Preferences for comfort care or pain management
- Decisions about artificial nutrition or hydration
- Organ donation wishes
- End-of-life preferences
A living will doesn’t mean “do not treat me.” It gives your medical team a guide when you can’t communicate. Without one, doctors may default to providing all possible treatment, which may or may not be what you’d want.
Healthcare Proxy Or Medical Power Of Attorney
A healthcare proxy or medical power of attorney names a specific person to make medical decisions for you if you can’t.
This person may be called an agent, proxy, surrogate, or representative depending on the state. Their role goes beyond what any written document can fully cover, they can talk to doctors in real time, respond to unexpected situations, and speak up for your wishes in ways a static document can’t anticipate.
This document works alongside a living will. The living will covers scenarios you thought to address ahead of time. The healthcare proxy handles everything else.

Advance Directive Documents At A Glance
| Document | What It Does | Who Uses It |
|---|---|---|
| Living Will | States your medical treatment wishes in writing | You, in advance |
| Healthcare Proxy / Medical POA | Names someone to make medical decisions for you | Your agent, if you cannot speak |
| POLST / MOLST | Physician-signed medical orders for current conditions | Seriously ill or elderly patients |
| DNR Order | Instructs medical staff not to perform CPR | Patients who specifically request it |
A POLST (Physician Orders for Life-Sustaining Treatment) or MOLST is a different kind of document. It’s a physician’s order, not just an expression of wishes. It’s typically used for people with serious illness or who are elderly. An advance directive is appropriate for most adults, regardless of age or health.
Why It Matters
Without clear documents, family members may not know your wishes, and they may disagree during an already stressful time.
Picture what could happen without one: you’re in an accident and unconscious, and doctors need to make decisions immediately. Family members may have different views about what you would have wanted. Some hospitals default to the most aggressive treatment available when guidance is absent. A document removes the guesswork and reduces the emotional burden on the people who love you.
Choose The Person Carefully
Pick someone who:
- Understands your values and will respect them, even if they personally disagree
- Can stay calm under pressure and communicate clearly with medical staff
- Is willing to follow your wishes even when family members push back
- Can handle difficult conversations with doctors without shutting down
- Is reliably reachable, not someone who travels constantly or is often out of contact
Talk to the person before naming them. Ask if they’re willing, and walk them through what you’d want in different scenarios. Name a backup too, in case your first choice can’t serve when needed.
Keep Copies Available
A document nobody can find may not help when it matters most.
Consider giving copies to:
- Your healthcare agent
- Backup agent
- Primary doctor, who can note it in your medical record
- Hospital system, if available (many allow you to register documents in advance)
- A trusted family member
- Your wallet or phone in summary card form, if your state provides one
Review it after major health changes, family changes, or if you move to a new state, advance directive laws vary widely, and some states require specific forms. For guidance on storing these documents safely, see What Documents Should Adults Keep Safe?
Frequently Asked Questions
Q: Do I need an advance directive if I’m young and healthy?
Yes. Accidents and sudden illness can happen at any age. An advance directive ensures your wishes are known and that someone you trust can speak for you if you can’t. It also removes a heavy burden from family members who would otherwise have to make decisions without any guidance.
Q: What is the difference between a living will and a healthcare proxy?
A living will is a written document that states your preferences for specific medical situations. A healthcare proxy (or medical power of attorney) names a person to make decisions for you. They work best together: the living will gives your agent guidance, and the agent handles situations the living will didn’t anticipate.
Q: Can I change my advance directive?
Yes. You can update or revoke an advance directive at any time as long as you’re mentally competent to do so. Let your doctor, agent, and family know if you make changes, and replace old copies with the updated version.
Q: Does a living will mean I won’t receive medical treatment?
No. A living will isn’t a blanket refusal of care. It typically addresses specific scenarios, such as being in a permanent vegetative state, where you can state whether you want life-sustaining treatment continued. You can request as much or as little intervention as you want.
