A living will is a written legal document that tells doctors and family which medical treatments you want, and which you refuse, if you are ever too sick or injured to speak for yourself. It takes effect only when you cannot communicate your own decisions, and it stays in force until you recover, revoke it, or die. Every adult can use one, not just people who are elderly or already ill.1Mayo Clinic. Living Wills and Advance Directives for Medical Decisions
What a Living Will Actually Decides
A living will focuses on life-sustaining treatment and end-of-life care. The common decisions it addresses are:
- Whether medical staff should attempt CPR if your heart stops, including chest compressions, electric shocks, and medications.
- Whether you want to be placed on a mechanical ventilator if you cannot breathe on your own.
- Whether you want artificial nutrition and hydration through a feeding tube or IV if you cannot eat or drink.
- What kind of comfort care and pain management you want, as opposed to treatment aimed at curing an underlying condition.
You can also use the document to record your wishes about organ and tissue donation.2National Institute on Aging. Preparing a Living Will The level of detail is up to you. Some people write broad instructions, such as refusing life-sustaining treatment in a permanent vegetative state. Others spell out their preferences scenario by scenario.1Mayo Clinic.

How It Differs From Documents That Sound Similar
People often confuse a living will with other planning tools. The differences matter because each fills a gap the others leave open.
Healthcare Power of Attorney
A healthcare power of attorney, sometimes called a healthcare proxy or medical power of attorney, names a specific person to make medical decisions for you when you can’t. A living will states what you want. A healthcare power of attorney picks who speaks for you. Most estate planning attorneys suggest having both, because written instructions cannot anticipate every possible medical situation, and your chosen agent can handle the ones your document doesn’t cover.3National Institute on Aging. Advance Care Planning: Advance Directives for Health Care
POLST and DNR Orders
A POLST (Portable Medical Orders for Life-Sustaining Treatment, under names that vary by state) is a medical order signed by a healthcare provider, not a document you write yourself. POLSTs are designed for people who are already seriously ill or frail, and they carry immediate clinical authority that emergency responders are trained to follow on the spot. EMTs generally cannot follow a living will or a healthcare power of attorney during an emergency; their job in that moment is to stabilize you for hospital transport. A DNR (Do Not Resuscitate) order is narrower still and covers only whether CPR should be attempted.2National Institute on Aging. Preparing a Living Will
Last Will and Testament
Despite the shared word, a living will has nothing to do with inheritance. A last will and testament controls what happens to your property after you die. A living will controls what happens to your body while you are still alive but cannot communicate.
What Happens If You Don’t Have One
If you become incapacitated without a living will, state law decides who makes medical decisions for you. In most states, that responsibility falls to your spouse, your parents if available, or your adult children.3National Institute on Aging. Advance Care Planning: Advance Directives for Health Care The exact priority order varies. Some states set a strict hierarchy in which a spouse outranks adult children. Others give healthcare providers more discretion in selecting a surrogate from available family and close friends.
The practical problems start when multiple family members qualify and disagree. Conflict can delay care and leave lasting rifts. For patients with no available family or friends at all, the options narrow to an ethics committee review, a physician making decisions alone, or a court appointing a guardian.4AMA Journal of Ethics. Who Makes Decisions for Incapacitated Patients Who Have No Surrogate or Advance Directive Guardianship proceedings can take weeks or months, and in the meantime medical teams often default to providing every possible treatment, whether or not that matches what you would have chosen.
A living will also lifts an enormous emotional weight off the people closest to you. Making life-or-death decisions on someone else’s behalf is painful. Knowing your actual wishes turns an agonizing judgment call into the simpler task of following your instructions.
How to Create One
Making a living will is simpler and cheaper than most people expect. You do not need a lawyer, though you may want one if your situation is complex.
Every state has its own advance directive form, and many are available as free downloads from state health department websites or nonprofit organizations. These forms walk you through the relevant decisions with checkboxes and fill-in sections tailored to your state’s requirements.2National Institute on Aging. Preparing a Living Will Read the instructions carefully, because witness and notarization rules differ from state to state.
If you have a complicated family situation, substantial assets, or want your living will drafted alongside a broader estate plan, an attorney can keep everything consistent and legally sound. Many attorneys bundle a living will with a healthcare power of attorney and other estate planning documents at a package rate.
The form itself is the easy part. The harder step, and the one most people skip, is an honest conversation with your family and your doctor about what matters to you. Your doctor can describe likely scenarios for your specific health conditions, and your family needs to understand your reasoning so they can back your choices rather than second-guess them later.
Making It Legally Valid
A living will must be written and signed by you while you have the mental capacity to understand what you’re agreeing to. Beyond that, requirements depend on your state. Most states require the document to be witnessed, commonly by two adults who are not named in your estate plan and are not part of your medical care team. Some states require notarization instead of or in addition to witnesses.1Mayo Clinic. Living Wills and Advance Directives for Medical Decisions Getting this wrong can make the document unenforceable, so follow your state’s form instructions precisely.
If you split your time between states or travel frequently, your living will may not automatically follow you. Most states have provisions recognizing out-of-state advance directives, but the rules vary. Some honor any valid out-of-state document. Others honor it only if it substantially meets their own requirements. A few states have no clear answer at all. Even when a document is technically recognized, terms and definitions can differ enough between states that your instructions might not be read the way you intended. The safest approach if you spend significant time in more than one state is to complete a separate advance directive for each state where you regularly receive care.
Can a Doctor Refuse to Follow It?
In rare cases, yes. A physician with a deeply held moral or religious objection to carrying out your instructions, for example withdrawing life support, may decline to do so. Ethical standards require that physician to refer you to another provider or institution willing to honor your wishes.5AMA Code of Medical Ethics. Physician Exercise of Conscience A doctor cannot simply ignore your living will and walk away. If this concerns you, raise your preferences with your healthcare providers before a crisis and confirm they are comfortable following your instructions.
Keeping It Usable
A living will locked in a safe deposit box is useless during an emergency at 2 a.m. The people who will need it have to be able to get to it. After completing your form, give copies to your healthcare proxy, your primary care doctor, and any specialists you see regularly, and ask your doctor’s office to add it to your medical record.2National Institute on Aging. Preparing a Living Will Some people also use digital advance directive registries, which store your documents online and make them accessible to healthcare systems electronically.
A living will is not a one-and-done document. Your medical situation, your family circumstances, and your values can all change. Review it every ten years or so, and sooner after any major life event: a divorce, the death of a spouse, a new diagnosis, or a significant change in an existing condition. Revisit it as well if the person you named as your healthcare proxy is no longer someone you trust or someone who is available.
Revoking a living will is straightforward in most states. You can destroy the document, write “revoked” across it, draft a new one that supersedes the old, or tell your doctor in writing that you’re revoking it. Some states also allow oral revocation. A few states automatically expire a living will after a set number of years if it is not renewed. Whatever method you use, notify everyone who has a copy so outdated instructions don’t create confusion when it matters most.
