Advance Directive and Healthcare Power of Attorney: Free State-Specific Requirements Guide
Figures and guidance last verified against official sources in July 2026.
Quick Answer
An advance directive tells healthcare providers what medical treatments you want if you cannot speak for yourself. A healthcare power of attorney names a specific person to make those decisions. Requirements differ by state — some require notarization, some require two witnesses, and some restrict who can serve as a witness. Using your state's official statutory form ensures it will be accepted.

Frequently Asked Questions
What is the difference between a living will and a healthcare power of attorney?
A living will details your specific medical treatment preferences (ventilation, feeding tubes). A healthcare power of attorney (or surrogate) appoints a trusted person to make medical decisions if you are incapacitated.
What is a POLST and how is it different from an advance directive?
A POLST (Portable Medical Order / Physician Orders for Life-Sustaining Treatment) translates advance directive wishes into actionable medical orders signed by a doctor, used primarily for seriously ill seniors.
Does my advance directive from one state work if I am hospitalized in another state?
Most states recognize valid out-of-state advance directives under reciprocity laws, though having your document match your primary state’s exact statutory format prevents delays.
Who cannot serve as a witness for an advance directive?
Most states prohibit your designated healthcare agent, treating physician, facility employees, or potential inheritance beneficiaries from serving as signing witnesses.
Does an advance directive expire?
No. Advance directives remain valid until revoked, replaced by a newer version, or specified with an expiration date in the document.
Where should I store my advance directive so it can be found in an emergency?
Give copies to your healthcare agent, primary care physician, local hospital system, and keep an accessible copy at home. Do NOT lock it in a safe deposit box.
Can I change or revoke my advance directive after I sign it?
Yes. You can revoke or amend your advance directive at any time while you retain decision-making capacity by completing a new document and notifying your doctor/agent.
What happens if I have no advance directive and cannot speak for myself?
State family consent laws determine who can make decisions (usually spouse, then adult children), or court guardianship proceedings may be required.
