How to write a living will: what to include and why

My uncle Ray had a stroke at 67. He survived, but for three weeks he couldn't talk or write or squeeze anyone's hand. He didn't have a living will. His wife Linda had to decide on her own whether to authorize a feeding tube, whether he'd want a ventilator if his breathing worsened. She made those calls in a hospital hallway, running on no sleep, with zero written guidance from a man who'd always said he'd "rather die than be hooked up to machines."

He'd said it at dinners. He'd said it when a neighbor was dying. But he'd never written it down. Linda made her best guesses. Ray recovered enough to come home. But she told me later that those weeks damaged something between them, because she was never sure she'd gotten it right.

A living will would have given both of them a script for that situation. This guide is about how to write one.

What a living will actually does

A living will is a legal document that tells your medical team what treatments you do and don't want when you can't speak for yourself. That's it. It's not a regular will (which covers your property after death), and it's not a healthcare power of attorney (which names a person to make decisions for you). A living will is your voice on paper, giving direct instructions about specific medical situations.

The document only activates under two conditions: you're unable to communicate, and your doctors have determined that you have a qualifying medical condition. In most states, that means a terminal illness, permanent unconsciousness, or an advanced irreversible condition. If you break your leg and go under anesthesia for surgery, your living will stays dormant. It's designed for situations where recovery to a decision-making state is unlikely.

Every state recognizes some form of living will, though the exact legal name varies. Some states call it a "declaration" or an "instruction directive." Five states (Alabama, Alaska, Indiana, Michigan, and Oregon) fold living will provisions into a broader advance directive form rather than offering a standalone document. The American Bar Association maintains a toolkit that covers these state-by-state differences.

Deciding what you actually want

This is the part people get stuck on, because the questions feel abstract until you're facing them. But you don't need medical expertise to fill out a living will. You need to think about a few scenarios honestly.

Life support. If your heart stops and doctors believe you won't recover to a meaningful level of consciousness, do you want CPR? If you can't breathe on your own and the prognosis is poor, do you want a ventilator? There's no right answer here. Some people want every intervention regardless of the odds. Some draw a line at mechanical breathing. Some want a time-limited trial, say, two weeks on a ventilator, and then reassess.

Artificial nutrition and hydration. If you can't eat or drink, do you want a feeding tube? This one trips people up because refusing food feels different from refusing a machine. But a feeding tube is a medical intervention, and you have the right to accept or decline it. The question is whether being kept alive through artificial feeding aligns with what you consider a life worth living.

Then there's pain management. Almost everyone wants it, but it's worth stating explicitly. You can specify that you want comfort care, meaning pain medication and symptom relief, even if you've declined other treatments. You can also note whether you're okay with pain medication that might shorten your life as a side effect. The National Institute on Aging has a plain-English guide to these medical decisions if you want more detail.

Your living will is also a good place to state whether you want to be an organ donor. This doesn't replace registering with your state's donor registry, but it reinforces your wishes in a legal document that your medical team will see.

Write a few sentences for each scenario. You don't need legal language. "I do not want to be kept on a ventilator if two doctors agree that I have no reasonable chance of recovering the ability to think, speak, and recognize my family" is perfectly clear. The point is specificity. "No heroic measures" is a phrase people use a lot, but it means different things to different doctors. Spell out what you mean.

Getting the right form for your state

You don't need to draft a living will from scratch. Every state has an approved form, and several nonprofits offer them free.

The National Hospice and Palliative Care Organization provides free advance directive forms for all 50 states and the District of Columbia through their CaringInfo program. Each state's packet includes a living will, a healthcare power of attorney, and instructions for completing and signing them. This is probably the easiest starting point.

Five Wishes is a widely used alternative that combines a living will and healthcare proxy into one document. It's written in everyday language and is legally valid in most states. It costs about $5 for a paper copy.

If you prefer working with a lawyer, expect to pay $150 to $500 for a living will as part of a broader advance directive package. An estate attorney is the right specialist here, not a general practitioner. For straightforward wishes, the free state forms work fine. If your medical situation is complicated, or if you have strong feelings about specific treatments, or if your family is likely to disagree with your choices, a lawyer adds a layer of protection.

Writing it: a step-by-step walkthrough

Here's what the process looks like in practice.

Download your state's form. Go to CaringInfo, select your state, and download the packet. Read the instructions page first because each state's signing requirements differ.

Fill in the treatment sections. Most forms use checkbox-style options: "I want / I do not want" for each treatment category. Some also include blank space for you to add custom instructions. Use it. The checkboxes cover the basics, but your personal context matters. If you've watched a parent die on a ventilator and know that's not what you want, say so. If your religious beliefs require certain treatments, write that down.

Here's an example of what a custom instruction might look like:

If I am diagnosed as permanently unconscious and two physicians confirm there is no reasonable chance I will regain awareness, I do not want mechanical ventilation, CPR, or artificial nutrition. I do want full comfort care including pain medication, even if it may hasten death. I want to be allowed to die at home if medically possible.

Compare that with: "No heroic measures." See the difference? The first version gives your medical team something they can actually follow.

Next, name your healthcare agent. Most state packets combine the living will with a healthcare power of attorney form. Fill out both while you're at it. Your living will handles the situations you anticipated. Your healthcare agent handles everything else. Together, they cover far more ground than either document alone. We have a separate guide to advance directives vs. living wills if you want a deeper look at how these two documents work together.

Finally, sign it according to your state's rules. Requirements vary. Some states need two adult witnesses. Others require notarization. A handful accept either. The witnesses usually cannot be your healthcare agent, your doctor, or anyone who would inherit from you. Read the instruction sheet carefully.

What to do with it after you sign it

A living will that sits in a filing cabinet doesn't help anyone. Distribution matters as much as the writing.

Give a copy to your primary care doctor and ask them to add it to your medical record. Most electronic health records systems can store advance directives. If you're hospitalized, the admitting staff should be able to pull it up.

Give a copy to your healthcare agent. Have a conversation, too. Walk them through your specific instructions and explain your reasoning. Linda would have had a much easier time if Ray had told her not just "I don't want machines" but "If I'm unconscious and not likely to wake up, the feeding tube and the ventilator are both a no. Keep me comfortable and let me go. I'd rather have three honest days than three machines months."

Keep a copy in your death binder or wherever you store your important documents. If you're using an online platform to organize your end-of-life plans, upload a scan there too.

Some people also carry a wallet card indicating that they have a living will and where to find it. This is especially useful if you're traveling or if you're taken to an emergency room where your regular doctor doesn't have privileges.

When to update it

A living will isn't a set-and-forget document. Update it whenever your life circumstances change in a way that might change your preferences.

Common triggers: a new medical diagnosis, a major surgery, a marriage or divorce, the death of your named healthcare agent, moving to a different state, or simply changing your mind. A 2014 study published in the BMJ Supportive & Palliative Care journal found that about one-third of patients changed their preferences about life-sustaining treatment over a two-year period. What you want at 40 may not be what you want at 70.

Updating is straightforward. Most states let you revoke a living will by destroying it, writing a new one, or verbally telling your doctor. If you write a new one, make sure the old copies are collected and replaced. Conflicting documents cause confusion.

Review it every few years even if nothing has changed. Read through the instructions you wrote and ask yourself if they still feel right. If they do, initial and date the document. If they don't, start a new one.

Common mistakes to avoid

People write living wills with good intentions and then make one of a few predictable errors.

Using vague language is the biggest one. Phrases like "no extraordinary measures," "let nature take its course," or "do everything reasonable" sound clear in your head but leave too much room for interpretation. A feeding tube is extraordinary to some people and basic care to others. Spell out each treatment category separately.

Not talking to your family is the second. A 2019 survey by The Conversation Project, a nonprofit affiliated with the Institute for Healthcare Improvement, found that while 92% of Americans say it's important to discuss end-of-life wishes, only 32% have actually had the conversation. Your written document will carry more weight, both legally and emotionally, if the people closest to you already know what's in it.

Assuming your spouse automatically gets to decide is the third. In many states, a spouse does have default decision-making authority. But default authority isn't the same as informed authority. If your spouse doesn't know what you want, the legal right to decide doesn't help them much. And if you're not married, most states don't give your partner any decision-making authority unless you've named them in a healthcare power of attorney.

Forgetting about the digital copy is worth mentioning, too. If your living will exists only as a piece of paper in a safe deposit box, it won't help during a medical emergency at 2 a.m. Make sure at least one other person can access a copy quickly.

A real situation where this mattered

I'll close with a story that isn't mine to tell in full, but the person it happened to gave me permission to share the outline.

A woman named Debra was diagnosed with early-stage ALS in her late fifties. She'd always been decisive, and within a month of the diagnosis she sat down and wrote a detailed living will. She specified at what point she wanted to stop interventions. She named her sister as healthcare agent. She wrote a separate letter to her sister explaining her reasoning, because she knew the decisions would be hard for someone who loved her.

When Debra eventually lost the ability to communicate, her sister didn't have to wonder what Debra would have wanted. She had a document, a conversation, and a personal letter. She told me the letter was what mattered most, because it said "I know this will be awful for you, and I'm sorry, and you're doing the right thing."

Your living will handles the medical part. But consider writing a letter alongside it. Tell the person who'll be making decisions that you trust them, that you've thought this through, and that following your wishes is what you need from them. When I Die Files gives you a place to write and store those letters, so the people you're counting on have both the legal instructions and the personal ones, together.

You can get a living will done in a single afternoon. Download the form, think through the questions, fill it out, sign it, and give copies to the people who need them. One afternoon, and the people who love you will never have to guess.
