What Is a Living Will? A Plain Guide

Most people think of a will as a document about money and property. A living will is something different. It speaks for you about medical care at a moment when you may not be able to speak for yourself.

It is one of the simplest legal documents an adult can prepare, and one of the most valuable for the people who love you. Here is a plain guide to what it does and how it works.

What a living will actually is

A living will is a written statement of the medical treatment you would or would not want if you become seriously ill or injured and cannot communicate your wishes. It is a type of advance directive, the general term for documents that guide health care decisions in advance.

The name causes confusion. A living will has nothing to do with your estate. It does not pass property, name heirs or appoint an executor. It applies while you are alive, and its purpose ends at death, when your last will takes over.

What it usually covers

Living wills typically address treatments that can prolong life when recovery is unlikely. Common topics include:

Resuscitation. Whether you want CPR if your heart or breathing stops.

Breathing machines. Whether you would accept mechanical ventilation, and for how long.

Feeding tubes. Whether you want artificial nutrition and hydration if you cannot eat or drink.

Comfort care. Your wishes on pain relief, hospice and dying at home or in a facility.

Many people also use the document to state wishes about organ donation or to explain the values behind their choices, such as whether quality of life or length of life matters more to them.

When it takes effect

A living will generally applies only when you cannot make or communicate decisions yourself, and often only in specific situations such as a terminal illness or permanent unconsciousness. The exact triggers depend on state law and on the wording of your document. As long as you can speak for yourself, your own decisions control.

Living will versus health care proxy

A living will states your wishes. A health care proxy, often called a health care power of attorney, names a person to make medical decisions for you when you cannot.

The two work best together. No document can predict every situation, so a trusted agent can apply your written wishes to circumstances you never imagined. Many states combine both in a single advance directive form.

How it differs from a POLST

Some seriously ill patients also complete a POLST or similar form, a medical order signed by a clinician that travels with the patient. A living will is your own statement, while a POLST is an order for emergency and medical staff to follow now. Names and rules for these forms vary by state.

How to make one valid

Requirements differ from state to state, so it is important to follow the rules where you live. In general:

You must be an adult of sound mind when you sign it.

Signing formalities apply. Many states require witnesses, a notary or both, and some limit who may serve as a witness, such as relatives or your health care providers.

State forms are widely available. Many state health departments, bar associations and hospitals offer free forms, and an estate planning attorney can tailor the language.

You can usually change or revoke a living will at any time while you are competent. Review it after major life events, such as a new diagnosis, a marriage or a divorce.

Making sure it is used

A living will only helps if people know it exists. Give copies to your doctor, your health care agent and close family, and ask that it be added to your medical records. Keep the original somewhere easy to find, not locked in a safe deposit box.

Most important, talk about it. A conversation with your family and your agent about what matters to you can prevent painful disagreements later.

The bottom line

A living will is a short document with a big job. It lets you shape your own care, spares loved ones from guessing and reduces the chance of conflict at a hard time. Because the rules vary by state, use your state's form or consult a licensed attorney to make sure yours is valid. This guide is general information, not legal advice.
