Advance care planning is the process of writing down what medical treatment you want, and naming someone to make decisions for you, in case illness or injury ever leaves you unable to speak for yourself. The core of a plan is two documents: a living will that records your treatment preferences, and a healthcare proxy that names a person to act on your behalf. Most states combine both into a single form. Done properly, the paperwork costs almost nothing and spares your family from guessing at high-stakes decisions under enormous stress.
When Your Plan Actually Takes Effect
Signing an advance directive does not hand control of your care to anyone else. The document stays dormant until a physician determines you lack the capacity to make your own decisions, which usually means illness, injury, or anesthesia has left you unable to understand your options or communicate a choice. Until that point, you remain fully in charge of every medical decision, and you can change or revoke the directive at any time.
People sometimes delay planning out of fear that signing means giving something up. The opposite is true. The directive protects your autonomy by recording what you want before a crisis takes away your ability to say it.
The Documents That Make Up a Plan
Living Will
A living will is a written statement describing the medical treatments you want or don’t want if you develop a terminal condition, enter a persistent vegetative state, or face another end-of-life scenario your state’s law recognizes. It gives clinicians direct instructions on interventions like mechanical ventilation, CPR, and artificial nutrition.
Every state has its own statute, and most provide a suggested or required form. Some offer simple checkboxes; others leave room for detailed personal statements. A living will works best when it goes beyond the checkboxes and explains the reasoning behind your choices, because medical situations rarely fit neatly into pre-printed categories.
Healthcare Proxy
A healthcare proxy, also called a durable power of attorney for healthcare or a healthcare surrogate designation, names a specific person to make medical decisions for you. Where the living will covers only the scenarios you anticipated, the proxy gives a real human the flexibility to respond to situations nobody predicted. The word “durable” means the authority survives your incapacity, which is the entire point.
The two documents complement each other. The living will tells your agent and your doctors what you value. The proxy gives someone the legal standing to interpret those values when a new complication arises at 2 a.m. and the living will doesn’t address it directly. Most states bundle both into a single form sometimes called an advance health care directive, though the underlying functions remain distinct.
POLST: A Portable Medical Order
A POLST (Portable Orders for Life-Sustaining Treatment, sometimes called MOLST depending on the state) is a medical order signed by a physician, nurse practitioner, or physician assistant. It is not an advance directive, and the difference matters in an emergency. EMTs are legally required to follow a POLST but generally cannot honor a living will or healthcare proxy at the scene. Once paramedics are called, they must stabilize and transport you; only after a physician evaluates you at the hospital can a standard advance directive guide care.
POLST forms are designed for people with serious illness or advanced frailty who face a realistic chance of a life-threatening event in the near future. They translate broader goals into specific medical orders covering CPR, intubation, antibiotics, and artificial nutrition. Forty-three states and Washington, D.C., have codified POLST programs or created officially recognized forms. If you have a serious medical condition, ask your doctor whether a POLST makes sense alongside your advance directive.
A Note on Psychiatric Directives
If you live with a condition that involves episodic loss of insight, such as bipolar disorder or schizophrenia, a psychiatric advance directive works like a standard directive but focuses on mental health treatment. It lets you document preferences for psychiatric medications, hospitalization at specific facilities, electroconvulsive therapy, and crisis management while you have capacity, and it takes effect when a clinician determines you lack that capacity due to a mental health crisis.1SAMHSA. A Practical Guide to Psychiatric Advance Directives
Choosing Your Healthcare Agent
Your agent is arguably the most important decision in the whole process. Pick someone who understands what matters to you and can stay composed when a surgeon needs an answer in the next ten minutes. This person doesn’t need to share your beliefs. They need to be willing to follow your instructions even when those instructions conflict with their own views.
Most states require your agent to be at least 18, and a couple set the minimum at 19. The American Bar Association recommends against choosing your treating physician, an employee of your healthcare facility, someone who already serves as agent for ten or more other people, or a court-appointed guardian.2National Institute on Aging. Choosing a Health Care Proxy A relative who happens to be a doctor is generally fine; someone with a direct financial or professional stake in your care decisions is not.
Name at least one alternate in case your first choice is unavailable when the moment arrives. Then have a direct, honest conversation with both about your values. An agent who learned your preferences from a document five years ago and never discussed them with you is an agent who will second-guess every decision.
The Treatment Decisions to Think Through
Resuscitation and Life Support
The most immediate decision is whether you want CPR if your heart stops. You also need to decide about mechanical ventilation. Some people authorize a time-limited trial, often 14 days, to see if the underlying condition improves, with instructions to withdraw the ventilator if recovery looks unlikely.
Artificial Nutrition and Hydration
Tube feeding and intravenous fluids keep the body alive when you can no longer eat or drink. Many people choose to accept these interventions temporarily but refuse long-term feeding if there is no realistic prospect of recovery. Specifying a trial period or a clear condition for stopping gives your care team concrete boundaries instead of open-ended obligations.
Palliative Care and Hospice
Your directive should say whether you prioritize comfort over life extension. Palliative care focuses on symptom relief and quality of life, and it can run alongside curative treatment at any stage of illness. Hospice care is specifically for people whose physician believes they have six months or less to live, and it replaces curative treatment with comfort-focused care.3National Institute on Aging. What Are Palliative Care and Hospice Care? Stating a preference helps your agent and doctors shift gears without agonizing over whether you would have approved.
Organ and Tissue Donation
If you want to donate organs or tissues, say so in your directive and tell your agent. There is a practical wrinkle: organ donation sometimes requires short-term life support to keep organs viable until the transplant team is ready. If your living will says “no ventilator under any circumstances,” it could conflict with your donation wishes. Consider language that authorizes temporary ventilation solely for the purpose of preserving organs for donation, if that reflects your intent.
Signing the Documents So They Hold Up
You must have decision-making capacity when you sign. That means you understand what the document does, what choices you’re making, and the consequences. If your capacity is later challenged, the witnesses who observed your signing can attest that you appeared competent and acted voluntarily.
Most states require two adult witnesses. Common disqualifications include being your named agent, a blood relative, someone who stands to inherit from your estate, or your treating physician. Some states accept notarization as an alternative to witnesses; others require both. Because requirements vary, use the form provided by your state’s department of health or attorney general’s office to be sure you meet local rules. State-set maximum notary fees range from $2 to $25, with most states capping the fee between $5 and $15. Community organizations and senior centers sometimes offer free notarization for these documents.
A growing number of states now allow remote online notarization, where you appear on a video call while a notary verifies your identity and watches you sign electronically. Before 2020, only a handful of states recognized this option; dozens have since passed laws or issued executive orders permitting it. Most of these are general remote notarization statutes that don’t specifically mention advance directives but don’t exclude them either. If mobility or distance makes an in-person signing difficult, check whether your state permits remote notarization for healthcare documents.
Distributing and Storing Your Plan
A perfectly executed directive that nobody can find in an emergency is worthless. Give copies to your agent, your alternate, and your primary care physician. If you see a regular specialist, give them a copy too. Most hospital systems allow patients to upload these documents into their electronic health records, which means the emergency department can pull them up even if you arrive unconscious at 3 a.m.
Keep the original somewhere accessible but secure. A home filing cabinet works; a safe deposit box that only you can open does not. Several states maintain advance directive registries where you can file your documents electronically for a small fee, typically around $10.4California Secretary of State. Registration of Written Advance Health Care Directive Tell your family where the documents are stored and who has copies. The goal is redundancy: if one copy is inaccessible, another should be within reach.
Keeping the Plan Valid Over Time and Across States
You can revoke or change your directive at any time as long as you have capacity. Most states allow revocation through a signed written statement or by verbally informing your treating physician. For the treatment preferences portion, many states let you revoke in any manner that communicates intent: tearing up the document, crossing it out, or telling someone. Revoking the designation of your agent is usually more formal, typically requiring a written and signed statement or direct communication to your supervising physician. When you revoke, make sure the revocation reaches everyone who has a copy.
Divorce creates a trap that catches people every year. In many states, divorcing or legally separating from someone you named as your agent automatically revokes that designation. If you actually want your former spouse to remain your agent after a divorce, you typically need to execute a new document explicitly saying so. Review your directive after any major life event: marriage, divorce, a new diagnosis, or the death of your named agent.
When a newer directive conflicts with an older one, the most recent document generally controls. There is an important exception: an agent generally cannot revoke a living will or CPR directive that you personally signed while competent. If your agent later signs a POLST that contradicts your earlier living will, the living will typically prevails. Aligning all your documents during each update matters, because conflicting paperwork forces your care team into legal uncertainty at the worst possible time.
If you split time between states, portability matters. Most states have laws recognizing out-of-state advance directives if the document was valid where signed or meets the requirements of the state where you’re receiving treatment. Some add a presumption of validity. The limits are in the definitions: terms like “life-sustaining treatment” or “terminal condition” differ between states, and a directive that explicitly refuses a feeding tube in one state might not authorize withholding it in another whose law requires more specific language. Snowbirds should consider having the directive reviewed against each state’s requirements, or executing a second directive that complies with the other state’s form.
When a Provider Can Refuse Your Directive
A healthcare provider may decline to follow your directive if the requested action conflicts with the provider’s personal conscience, the institution’s policy, or accepted medical standards.5National Institute on Aging. Advance Care Planning – Advance Directives for Health Care A Catholic hospital, for example, may refuse to withdraw certain life-sustaining treatments based on its ethical and religious directives. A physician might refuse to stop treatment if they believe the condition is recoverable.
The provider cannot simply ignore your directive, however. They must notify your agent immediately and make reasonable efforts to transfer your care to a provider who will honor your wishes. If you know you’ll be receiving care at a facility with specific religious or ethical policies, discuss potential conflicts in advance and consider identifying backup providers.
What It Costs, and What Happens If You Skip It
You don’t need an attorney to create an advance directive. Every state offers free or low-cost forms through its department of health, attorney general’s office, or secretary of state’s website. Filling out the form yourself and having it properly witnessed and notarized can cost as little as $5 to $25 depending on your state’s notary fees. Medicare covers an annual advance care planning conversation with your doctor as part of your wellness visit, and many private insurers cover similar discussions.
If your situation is complicated by a blended family, complex medical history, or assets that create potential conflicts, an attorney can draft a full set of documents. Attorney fees for a package that includes a living will and healthcare power of attorney typically range from $250 to $400 for individual documents and $475 to $1,175 for comprehensive packages that bundle advance directives with other estate planning documents.
If you become incapacitated without any directive, roughly 44 states have default surrogate consent laws that assign decision-making authority to family members in a ranked order. The typical hierarchy starts with your spouse, then moves to adult children, parents, and siblings, though the exact order and eligible relatives vary. These laws are a safety net, but they create real problems. When multiple family members share the same priority level and disagree, the result is often delay, conflict, and sometimes litigation. A court may need to appoint a guardian, which costs money and time your medical situation may not afford. The statute follows a checklist, not your preferences, and families without clear directives sometimes end up in guardianship proceedings that cost thousands of dollars, take weeks or months, and produce results that may not reflect what the patient would have wanted.
