These two terms are used interchangeably so often that most people assume they are the same thing. They are not. In Pennsylvania, a living will and a healthcare power of attorney are separate legal documents that serve different purposes, apply in different circumstances, and are governed by different statutes.
What Is a Living Will in Pennsylvania?
A living will tells your physicians what to do if you are in one of two specific situations:
- Terminal condition: an incurable, irreversible condition that will result in death regardless of treatment.
- Permanent unconsciousness: you are permanently unaware of yourself and your environment with no reasonable expectation of recovery.
Under 20 Pa.C.S. § 5443, a properly executed living will directs your attending physician to withhold or withdraw life-sustaining treatment, including artificial nutrition and hydration. It must be signed by you and witnessed by two individuals.
The critical limitation: a living will only applies in those two situations. If you are incapacitated but not terminal and not permanently unconscious (recovering from a serious stroke, in a coma with a chance of recovery, or suffering from advanced dementia), your living will does not apply. Without a healthcare power of attorney, no one has legal authority to make decisions on your behalf.
What Is a Healthcare Power of Attorney?
A healthcare power of attorney (sometimes called a healthcare proxy) appoints a healthcare agent to make medical decisions when you are unable to make them yourself. This is governed by 20 Pa.C.S. § 5456.
Unlike a living will, a healthcare power of attorney applies any time you are incapacitated, covering surgical decisions during emergencies, rehabilitation choices after a stroke or accident, mental health treatment, decisions about where you receive care, and end-of-life decisions.
Your agent's authority activates when your attending physician determines you lack capacity. You can include specific instructions or limitations, or give your agent broad discretion.
What Is a Combined Advance Directive?
The term advance directive often refers to a single combined document that includes both a living will declaration and a healthcare power of attorney. This combined approach ensures all your healthcare wishes are captured in one document, reducing confusion. It typically appoints a healthcare agent and alternates, includes your living will declaration, addresses specific preferences regarding pain management, organ donation, and artificial nutrition, and specifies any limitations on your agent's authority.
Common Mistakes
Having only a living will. This is the most common gap. If you are in a car accident and incapacitated but not terminal, your family has no legal authority to consent to surgery without a healthcare power of attorney. The only alternative is an emergency guardianship: expensive, time-consuming, and stressful.
Confusing healthcare and financial powers of attorney. A financial power of attorney covers bank accounts, real estate, and legal matters. It gives zero authority over medical care. You need both.
Not talking to your agent. The document gives legal authority, but it works best when your agent knows what you would want. Have the conversation about life support, long-term care, and quality of life.
Failing to update. If your named agent has died, moved away, or you have divorced a spouse you appointed, your documents need updating. Pennsylvania law automatically revokes appointment of a former spouse as healthcare agent upon divorce unless the document states otherwise.
