Advance Directives, Living Wills, and Healthcare Proxy Explained
Reviewed by Everendium Editorial Team · Last reviewed August 18, 2026
Quick answer
An advance directive is an umbrella term for documents stating your medical wishes; a living will specifies the treatments you do or don't want; a healthcare proxy (or medical power of attorney) names a specific person to make decisions for you if you can't. Most people benefit from having both pieces in place, not just one.
These three terms get used somewhat interchangeably, but understanding how they actually relate to each other helps you make sure you have the right documents in place.
Advance directive: the umbrella term
An advance directive is a general term covering legal documents that state your healthcare wishes in advance — it can include a living will, a healthcare proxy designation, or both together in one document, depending on your state’s specific forms.
Living will: your specific wishes
A living will specifies which medical treatments you do or don’t want in specific situations — for example, whether you’d want life-sustaining treatment if there’s no reasonable chance of recovery. This document speaks directly to situations it addresses, but can’t anticipate every possible scenario.
Healthcare proxy: a person, not just a document
A healthcare proxy (sometimes called a medical power of attorney) names a specific trusted person to make medical decisions on your behalf if you can’t communicate them yourself. This person can use their judgment for situations your living will doesn’t specifically cover.
Living Will
- ✓States specific treatment wishes
- ✓A document, not a person
- ✓Can't cover every scenario
Healthcare Proxy
- ✓Names a decision-making person
- ✓Uses judgment for the unexpected
- ✓Complements the living will
Most people benefit from having both, not just one or the other.
Why most people benefit from both
A living will alone can’t cover every possible medical scenario. A healthcare proxy alone doesn’t give that person specific guidance on your actual wishes. Together, they cover both the specific situations you can anticipate and the ones you can’t.
Getting started
Many states provide free, legally valid advance directive forms — often available through a hospital, state health department, or organizations focused on advance care planning. A lawyer can help if you’d like something more customized to a complex situation.
Specific requirements and terminology vary by state. This is general educational information, not legal advice — consider consulting an attorney for guidance specific to your state.
Frequently asked questions
Do I need both a living will and a healthcare proxy?+
Most experts recommend having both — a living will covers situations your document specifically addresses, while a healthcare proxy gives a trusted person authority to make judgment calls for situations you didn't anticipate.
Is a healthcare proxy the same as a medical power of attorney?+
These terms are often used interchangeably, though exact terminology varies by state — both generally refer to naming someone to make medical decisions on your behalf.
Do I need a lawyer to create these documents?+
Not necessarily — many states provide free, legally valid advance directive forms, though a lawyer can help if your situation is more complex or you want documents customized further.
Can I change my advance directive later?+
Yes — these documents can typically be updated at any time as your wishes or health situation changes, and it's worth revisiting them periodically.
