What Is an Advance Directive? A Plain-English Guide for Families

What is an advance directive?

An advance directive is a legal document that records your medical wishes and designates someone you trust to make healthcare decisions on your behalf if you become unable to make them yourself.

The term "advance directive" is an umbrella that covers two related documents often combined into one:

A living will describes the specific types of medical treatment you do or do not want in different scenarios — for example, whether you want life support continued if you are in a permanent vegetative state, or whether you want aggressive treatment attempted if survival is unlikely.

A healthcare power of attorney (also called a healthcare proxy or durable power of attorney for healthcare) names a specific person — your healthcare agent — to make medical decisions for you when you cannot make them yourself.

Together, these documents give healthcare providers a clear record of your wishes and designate someone with legal authority to act on your behalf.

Why does an advance directive matter?

Without an advance directive, doctors are legally required to do everything medically possible to keep you alive — even if that outcome is not what you would have wanted. Your family may be asked to make difficult decisions in a crisis, without knowing your preferences, and without legal authority to act unless your state's default rules give them that power.

The absence of an advance directive causes real harm. Families are forced to guess. They disagree. They feel guilty. Medical teams proceed with aggressive treatment that the patient would have refused if asked. These situations are painful, expensive, and entirely avoidable.

An advance directive removes the guesswork. It tells your doctors and your family exactly what you want — while you are calm, informed, and able to make a deliberate choice.

Who needs an advance directive?

Everyone over the age of 18.

Most people associate advance directives with the elderly or seriously ill. But a serious accident, sudden illness, or surgical complication can leave any adult unable to communicate their wishes. An advance directive protects you regardless of your age or health status.

The time to create one is now — before a health crisis, not during one. Creating an advance directive while you are healthy is straightforward and typically takes less than an hour.

What does a living will typically include?

A living will documents your preferences across several categories of medical treatment:

Life-sustaining treatment. Do you want cardiopulmonary resuscitation (CPR) attempted if your heart stops? Do you want to be placed on a mechanical ventilator if you cannot breathe on your own? Your preferences may differ depending on whether recovery is expected.

Artificial nutrition and hydration. Do you want a feeding tube or intravenous fluids if you cannot eat or drink on your own? Many people want these measures used temporarily during recovery but do not want them used indefinitely to prolong dying.

Comfort care (palliative care). Most advance directives include a clear preference for comfort-focused care — pain management, dignity, and quality of life — even if the person has declined aggressive life-prolonging treatment. This is usually the default wish.

Organ and tissue donation. Some advance directives include organ donation preferences, though this is also documented separately on a driver's license or organ donor registry.

Dementia-specific instructions. Some people choose to add instructions specific to dementia — for example, whether they want certain treatments if they reach a late stage of cognitive decline and can no longer recognise family members.

What does a healthcare power of attorney include?

A healthcare power of attorney (HCPOA) designates a specific person — your agent — to make healthcare decisions for you when you cannot make them yourself.

Your agent can:

• Consent to or refuse medical treatment on your behalf
• Access your medical records
• Talk with your doctors and care team
• Make decisions your living will did not anticipate

Choosing the right agent is as important as the document itself. The ideal healthcare agent is:

• Someone you trust completely to honor your wishes, even under pressure
• Someone who can stay calm and communicate clearly in a medical setting
• Someone who is geographically available or can travel quickly if needed
• Someone who is not so emotionally close to you that they would struggle to follow your instructions

Common choices are a spouse or partner, an adult child, a sibling, or a close friend. You can also name an alternate agent in case your first choice is unavailable.

Talk to your intended agent before naming them. Make sure they understand your values and wishes, and that they are willing to serve.

How do you write an advance directive?

Step 1: Choose your form. Each US state has its own official advance directive form, and most states require that it be completed using their specific format to be legally valid. Find your state's form through your state health department website, a local hospital, or an estate planning attorney.

Step 2: Fill in your wishes. Work through each section of the form carefully. Be specific. Vague instructions like "I want to be comfortable" are harder for doctors and agents to act on than clear preferences for specific treatments.

Step 3: Name your healthcare agent. Complete the healthcare power of attorney section. Include your agent's name, relationship to you, and contact information. Name an alternate agent.

Step 4: Sign and witness. Most states require two adult witnesses who are not your healthcare agent, not related to you, and not beneficiaries of your estate. Some states also require notarisation. Follow your state's requirements exactly — an improperly witnessed directive may not be legally valid.

Step 5: Share copies. Give copies to:

• Your healthcare agent
• Your primary care doctor (to be added to your medical record)
• Any specialists treating a chronic condition
• Your hospital of choice (many hospitals allow you to register it in their system)
• Your family members

Step 6: Store it accessibly. Keep the original in a place your agent and family can access quickly. A home safe is fine. A safety deposit box is not — it may be inaccessible on short notice. A secure digital vault that allows family access is a practical option.

What is a POLST and how is it different?

A POLST (Physician Orders for Life-Sustaining Treatment, also called MOLST, MOST, or POST in some states) is a medical order signed by a physician that translates your advance directive preferences into immediate, actionable instructions for emergency responders.

The key difference: an advance directive is a legal document that guides future decision-making; a POLST is a medical order that must be followed immediately. A POLST is typically appropriate for people with serious illness or advanced age.

If you have a life-limiting condition, ask your doctor whether a POLST is appropriate for you. Your advance directive informs the content of your POLST.

How do you change or cancel an advance directive?

You can update or revoke an advance directive at any time, as long as you are mentally competent to do so.

To update it: complete a new form, sign and witness it properly, and distribute the new version to everyone who has the old one. Destroy old copies to prevent confusion.

To revoke it: inform your doctor and healthcare agent verbally or in writing. You can also physically destroy the document. Oral revocation is generally recognised, but a written revocation is more reliable.

Review your advance directive whenever your health situation changes significantly, after a major life event (marriage, divorce, death of a named agent), or at least every five years to confirm it still reflects your wishes.

Frequently asked questions

Does an advance directive expire?

Legally, most advance directives do not expire. However, they can become outdated if your wishes change, if your named agent is no longer appropriate, or if your state updates its requirements. Review yours every few years.

What if I am traveling out of state?

Most states will honor an advance directive from another state if it was valid where it was signed. However, this is not universal. If you spend significant time in multiple states, consider completing a directive that meets the requirements of both states, or use a form that explicitly states it is intended to be valid in all jurisdictions.

Can my family override my advance directive?

No. A properly executed advance directive is legally binding. Your named agent must follow your documented wishes, and your family cannot override them. This is one of the most important reasons to have one — it protects your wishes from well-meaning family members who might push for different treatment.

What if I change my mind in the hospital?

If you are conscious and competent, you can change your mind at any time. You have the right to refuse or accept any treatment regardless of what your advance directive says. Your directive only takes effect when you are unable to communicate your wishes yourself.

Is an advance directive the same as a DNR?

No. A Do Not Resuscitate (DNR) order is a specific medical order, signed by a physician, that instructs medical staff not to attempt CPR if your heart stops. It is a narrower document covering a single decision. An advance directive is broader, covering many types of treatment and designating an agent. Your advance directive can include a preference for no resuscitation, which your doctor can then translate into a formal DNR order.

Do I need a lawyer?

No. Most advance directive forms are designed to be completed without legal assistance. Completing your state's official form, having it properly witnessed, and sharing it with your doctor and agent is sufficient for most people. An attorney is helpful if you have complex medical or family circumstances, or if you are completing a comprehensive estate plan at the same time.
