A living will consists of a few standard building blocks: your identifying information, a declaration that the document is your living will, specific instructions on the medical treatments you want or refuse if you cannot speak for yourself, a statement that you signed voluntarily while mentally competent, and your dated signature executed with the witnesses or notarization your state requires.1National Institute on Aging. Preparing a Living Will The treatment instructions are the heart of it. Everything else exists to make those instructions enforceable.
Identifying Information and Declaration of Intent
The document opens by identifying you clearly: full legal name, date of birth, and address. This sounds obvious, but a hospital pulling your file in a crisis needs no ambiguity about whose wishes it is reading.
Right after your identification comes a declaration of intent. This is a short statement saying that the document is your living will and that you want it followed when you can no longer make or communicate medical decisions on your own. The declaration removes any question about the paper’s purpose and signals to doctors and family that what follows is binding, not a draft or a wish list.
Treatment Instructions You Spell Out
The treatment section is where you accept or refuse specific interventions. Vague phrasing like “no extraordinary measures” invites arguments among family members and doctors. The stronger approach is to address each major intervention on its own, and to say under what conditions each preference applies. Many state-provided forms walk you through this treatment by treatment.
The common life-sustaining treatments to address include:
- Mechanical ventilation: a machine that breathes for you through a tube in your throat when your lungs cannot function.
- CPR: chest compressions, electric shocks, and medications used to restart your heart if it stops.
- Artificial nutrition and hydration: food and fluids delivered through a tube in your nose or stomach, or intravenously, when you can no longer eat or drink.
- Dialysis: a machine that filters waste from your blood when your kidneys fail.
- Pacemakers and implantable defibrillators: devices that regulate or restart your heartbeat.
Decisions about these treatments are among the most common choices people record in a living will.1National Institute on Aging. Preparing a Living Will You do not have to pick all-or-nothing. You might accept short-term ventilator use after surgery while refusing it if you are in a permanent coma. You might accept a feeding tube for a time-limited trial while refusing one indefinitely. Pair each preference with the circumstances that trigger it.
Beyond the big machines and procedures, your living will can include instructions about comfort care. This means directing the medical team to focus on managing pain and keeping you comfortable rather than prolonging your life. You can request maximum pain relief even if the medication carries a risk of shortening your life. For many people this is the most straightforward part to write, because the goal is simple: dignity and minimal suffering.
A living will can also record your wishes on organ and tissue donation. If you want to donate, saying so in the document alerts the medical team. The team will maintain life support briefly to preserve organs for transplant, then follow your other instructions.1National Institute on Aging. Preparing a Living Will
Competency Statement and Signature
Toward the end of the document, you include a statement that you are signing voluntarily and were mentally competent at the time. Courts and healthcare providers take this seriously. A living will signed by someone who lacked the capacity to understand what they were doing can be challenged and thrown out.
Your dated signature follows. The signature is what converts the written preferences into a legal instrument, and the date establishes which version controls if an older copy surfaces later.
Witnesses or Notarization
The signature alone is rarely enough. Every state requires you to sign and date the document, and most require more. The common requirement is two adult witnesses who watch you sign and then sign the document themselves.
Most states disqualify certain people from serving as witnesses: anyone who stands to inherit from your estate, anyone related to you by blood or marriage, and anyone involved in your medical care. These restrictions exist to prevent a witness with a financial or personal interest from pressuring you into signing.
Some states accept notarization as an alternative to witnesses, and a few require both. Having your signature notarized adds a layer of protection because the notary verifies your identity and confirms you signed willingly. Even where notarization is optional, it makes the document harder to challenge later. A handful of states have no witness or notarization requirement at all, though this is the exception. If you split time between two states, using both witnesses and a notary covers you under either state’s rules. The extra formality costs little and can prevent a legal fight at the worst possible time.
A Healthcare Agent Is a Separate Document
A common misconception is that naming a healthcare agent happens inside the living will. In most states, you appoint an agent through a separate document called a durable power of attorney for healthcare.2Legal Information Institute. Durable Power of Attorney for Health Care Some states combine both into a single advance directive form, letting you name an agent and list your treatment preferences on one set of pages. Whether your state uses a combined form or two separate documents, the agent’s role is the same: to step in and interpret your wishes when a situation falls outside what the living will spells out.
Your agent is legally required to follow the instructions in your living will where they apply. For gaps, the agent makes decisions based on your known values. If you want the full package, draft both documents at once and name a successor agent in case your first choice is unavailable when a crisis hits.
Pregnancy Clause
If you could become pregnant, this is one of the most overlooked elements of advance directive drafting. More than half of states restrict whether a living will can be followed if the person who signed it is pregnant. About ten states completely invalidate a pregnant person’s living will regardless of how far along the pregnancy is. Another roughly seventeen states invalidate the living will only if the fetus could potentially reach viability with continued life-sustaining treatment. A few of those make an exception if continuing treatment would cause severe physical harm to the pregnant person.
The remaining states either impose no pregnancy restriction or allow you to include specific instructions about what should happen if you are pregnant when the document takes effect. If pregnancy is a possibility, add a pregnancy clause stating whether you want your instructions to apply. At minimum, your wishes are then on record even in states that limit enforcement.
When the Document Actually Takes Effect
Knowing what goes in the document is only half the picture. A living will does not kick in the moment you sign it. It sits dormant until two conditions are met: you lose the ability to make or communicate your own medical decisions, and a physician certifies that you have a qualifying condition. In most states the certifying physician must confirm in writing that you are terminally ill, permanently unconscious, or in a comparable end-stage condition before your instructions become binding on the medical team.
This matters for how you draft. A temporary loss of consciousness after a car accident does not automatically activate your living will. The document governs situations where recovery is not expected, not every moment you are unable to speak. If you regain the ability to communicate, you resume making your own decisions and the living will returns to standby. Writing your treatment instructions with that triggering context in mind keeps your preferences from being applied too narrowly or too broadly.
