Writing an advance directive involves two core tasks: putting your medical treatment preferences in writing (a living will) and naming someone to make healthcare decisions if you can’t speak for yourself (a healthcare power of attorney). Both documents are straightforward to create without a lawyer, though each state has its own rules about signatures, witnesses, and notarization. The process takes most people a few hours of thought and conversation, plus a short time with the paperwork itself.
What an Advance Directive Actually Includes
An advance directive is an umbrella term for two separate legal documents that work together. The first is a living will, which spells out the specific medical treatments you do and don’t want if you’re unable to communicate. The second is a durable power of attorney for health care (also called a healthcare proxy), which names a person authorized to make medical decisions on your behalf. You can complete one or both, but having both gives you the most protection.
These documents only take effect when you can’t speak for yourself. That might mean you’re in a coma, in the late stages of dementia, terminally ill, or seriously injured. As long as you can communicate, your doctors will ask you directly.
Step 1: Choose Your Healthcare Agent
Your healthcare agent is the person who will interpret your wishes and make real-time medical decisions when you can’t. This choice matters more than any box you check on a form, because no document can anticipate every scenario. Your agent fills in the gaps.
In most states, this person must be at least 18 (19 in Alabama and Nebraska) and of sound mind. The American Bar Association recommends against choosing your doctor, anyone employed by your healthcare or residential care facility, or a government employee financially responsible for your care. Beyond those restrictions, pick someone based on these practical questions:
- Will they follow your wishes? Some people love you deeply but would struggle to let go. You need someone who can honor what you want, even if it’s hard.
- Can they handle pressure? Family members, friends, and doctors may push in different directions. Your agent needs to stay firm.
- Are they reachable? Someone who lives nearby or would travel quickly is more practical than a sibling across the country.
- Can you talk openly with them? If you’re uncomfortable discussing death and medical treatment with this person, they’re probably not the right choice.
Name a backup agent, too. If your first choice is unavailable or unable to serve, you don’t want the decision defaulting to someone you haven’t chosen.
Step 2: Decide on Specific Medical Treatments
The living will portion asks you to think through several categories of life-sustaining treatment. You don’t need medical knowledge to complete it. You just need to consider what quality of life means to you and where your boundaries are.
Most forms cover these interventions:
- CPR and resuscitation: Whether you want chest compressions, electric shocks, or medications to restart your heart if it stops.
- Mechanical ventilation: Whether you want a machine to breathe for you through a tube in your throat.
- Artificial nutrition and hydration: Whether you want fluids and nutrition delivered through a tube into your stomach or an IV if you can no longer eat or drink.
- Dialysis: Whether you want a machine to filter your blood if your kidneys fail.
- Comfort care: Whether you want treatment focused only on managing pain and symptoms rather than extending life.
For each of these, think about the circumstances. You might want aggressive treatment after a car accident with good recovery odds, but not if you’re in the final stages of an incurable illness. Good advance directive forms let you specify these distinctions rather than giving a blanket yes or no.
Go beyond vague phrases when writing your preferences. Saying “I don’t want to be kept alive on machines” sounds clear but is open to wide interpretation. Instead, specify which treatments you’d accept, under what conditions, and when you’d want them stopped. If you’d want a ventilator tried for two weeks after a stroke but not indefinitely, say so.
Step 3: Have the Conversation
The paperwork is only as useful as the conversations behind it. Talk with your healthcare agent in detail about your values, not just your checkbox answers. Explain what you consider an acceptable quality of life. Are you okay being alive but unable to recognize family? Would you want treatment if you could never live independently again? These are the gray areas your agent will actually face.
Starting these conversations feels awkward. One practical approach: frame it as planning, not as a crisis. You might say something like, “I’m not bringing this up because something is wrong. I just want us to talk about this now so we’re not figuring it out in an emergency.” Ask your family members open-ended questions, too. If a loved one says they “don’t want to be a burden,” ask what that means to them specifically. If they say they “don’t want to suffer,” ask what kind of suffering they’re most concerned about: physical pain, loss of independence, or something else.
Talk with your doctor as well. They can explain what these treatments actually look and feel like, which helps you make more informed choices. A ventilator, for example, involves sedation and a tube down your throat. Understanding that reality may change your preferences.
Step 4: Complete and Sign the Forms
Every state has its own advance directive form, and you can typically find yours for free through your state’s health department, bar association, or organizations like the National Hospice and Palliative Care Organization. You do not need a lawyer to complete these forms, though consulting one is an option if your situation is complex.
State requirements for making the document legally valid vary, but most follow a similar pattern. In many states, two witnesses over age 18 must watch you sign and then sign the document themselves. At least one witness typically cannot be related to you by blood, marriage, or adoption. Your healthcare agent, your doctor, and anyone employed by your doctor or care facility generally cannot serve as witnesses. Some states require notarization instead of or in addition to witnesses.
Because requirements differ, use your own state’s form rather than a generic template. If you split time between two states, consider completing directives that comply with both.
Step 5: Distribute and Store Copies
An advance directive that sits in a filing cabinet does nothing in an emergency. Once your documents are signed, give copies to your healthcare agent, your backup agent, your primary care doctor, and any specialists who treat you regularly. If you’re admitted to a hospital or a new healthcare facility, bring a copy and ask that it be added to your medical record.
Keep the original in a place that’s easy to find, not in a safe deposit box that no one can access at 2 a.m. A fireproof home folder works. Some people also carry a wallet card noting that they have an advance directive and listing where it’s stored and how to reach their healthcare agent. Several states and health systems now offer electronic registries where you can upload your documents for quick access.
How Advance Directives Differ From DNR and POLST Orders
There’s widespread confusion about how these documents relate to each other. An advance directive is something you write in advance to express your general treatment preferences. A DNR (do not resuscitate) order is a specific clinical instruction written by your doctor and placed in your medical record. You don’t need an advance directive to have a DNR. Just tell your doctor your preference, and they’ll write the order.
A POLST or MOLST form (Portable Orders for Life-Sustaining Treatment or Medical Orders for Life-Sustaining Treatment) is a clinical order signed by both you and your physician. It’s typically used for people with serious illnesses and translates your wishes into specific medical orders that first responders and emergency staff follow immediately. Unlike an advance directive, a POLST travels with you between care settings.
The confusion is real even among physicians. One national study found that 78% of doctors equated having any advance directive with an automatic DNR order, even when the directive specifically requested resuscitation. This is exactly why being detailed and specific in your documents matters, and why giving copies directly to your medical team is essential.
Psychiatric Advance Directives
If you live with a mental health condition, a psychiatric advance directive lets you document your treatment preferences for a future mental health crisis, when you may not be able to make clear decisions. These cover preferences for specific medications (including ones you want to refuse), whether you’d prefer alternatives to hospitalization, which hospitals you’d want to go to or avoid, and who should be contacted. You can also name a substitute decision maker specifically for psychiatric care.
In studies of completed psychiatric advance directives, about two-thirds of people documented a preference for alternatives to hospitalization, and the vast majority specified which medications they’d consent to and which they’d refuse. Many also included practical instructions like who should care for pets or dependents during a crisis. These documents increase a sense of control during periods when the illness itself can strip that away.
When to Update Your Directive
An advance directive isn’t a one-time task. Review yours whenever your life circumstances change meaningfully. Three situations should always trigger a review: divorce or a major family change (especially if your ex-spouse is your named agent), a new serious diagnosis, and a significant decline in your health or independence.
Moving to a new state is another trigger. Most states recognize advance directives executed in other states as validly signed, but they’ll interpret the document under local law. Definitions and limitations vary enough that your original intentions could be misread. If you relocate, complete a new directive using your new state’s form.
Even without a major life event, re-read your directive every few years. Your values and priorities at 45 may look different at 65. When you update, destroy old copies and redistribute the new version to everyone who had the previous one.
