When an illness or injury leaves a patient unable to talk with doctors, someone still has to decide whether to continue treatment, transfer to hospice care, or pursue aggressive intervention. Without instructions on file, that decision can fall to family members guessing at what a loved one would have wanted, or in some cases to a court. Two documents settle the question ahead of time: a living will that states specific treatment preferences, and a health-care proxy that names a person to decide anything the living will does not cover. For older adults managing chronic conditions or simply planning ahead, putting both in place is a low-cost step that can prevent a costly and drawn-out legal process later.
What a Living Will Actually Decides
A living will is a legal document that tells doctors how a patient wants to be treated if they cannot make their own decisions about emergency treatment, according to the National Institute on Aging. It lets a person specify which common medical treatments they would want, which ones they would want to avoid, and the conditions under which each choice applies, covering scenarios such as CPR, mechanical ventilation, and tube feeding. Because it is drafted while a person is still able to communicate clearly, a living will removes ambiguity for both the medical team and the family at a moment when emotions run high and decisions have to be made quickly.
The stakes of leaving that decision to guesswork are higher than most people assume. Research cited by the institute found that people guessed nearly one out of three end-of-life decisions incorrectly when acting on behalf of a loved one who had never put a plan in writing. A living will closes that gap by letting the patient, not a grieving family member, make the call in advance.

Naming a Health-Care Proxy Through a Power of Attorney
The second document, a durable power of attorney for health care, names a health-care proxy — also called a representative, surrogate, or agent — who can make medical decisions for the patient whenever the patient cannot communicate those decisions personally. A proxy can be authorized in addition to a living will or instead of one, and it is especially useful for situations a living will cannot anticipate, such as a sudden stroke or a car accident where no specific instruction was ever written down. The institute recommends choosing someone familiar with the patient’s values and discussing preferences with that person directly, rather than assuming they will simply know what to do.
Advance directives are not permanent once signed. The recommendation is to treat them as living documents, reviewed at least once a year and updated after a major life event such as retirement, a move out of state, or a significant change in health. A copy should go to the proxy, the patient’s doctors, and close family, since a directive that sits untouched in a drawer cannot help anyone in an emergency.
Beyond the two core documents, a patient can also set up narrower orders for specific situations, such as a do-not-resuscitate order that tells medical staff not to attempt CPR, or a physician order for life-sustaining treatment that translates a patient’s wishes into a standing medical order hospital staff can act on immediately. These forms supplement, rather than replace, a living will and a health-care proxy, and are typically completed with a doctor once a patient is closer to a decision point such as a serious diagnosis.
What Happens Without a Plan in Place
Without either document, state law determines who is authorized to make medical decisions on a patient’s behalf — typically a spouse, then parents, then adult children. An unmarried partner who was never formally named as proxy can be excluded from that chain entirely, and a patient with no available family may have a physician, or eventually a court, weigh in instead.
When no one holds legal authority and a decision cannot wait, families sometimes have to turn to the court system for a guardianship. That process, according to the Administration for Community Living, gives a judge the power to decide whether an adult is incapacitated and, if so, to appoint someone else to make decisions on their behalf — including where they live, what medical care they receive, and who they can see. The agency lists advance directives among the formal arrangements that can keep a guardianship proceeding from becoming necessary in the first place, leaving decision-making with a person the patient already trusts rather than a court-appointed stranger.
Both documents can typically be completed for little or no cost, without a lawyer, through state-specific forms available from a state attorney general’s office or a local Area Agency on Aging. The paperwork itself is simple; the harder part, according to the institute, is the conversation that has to happen before it is signed.
