A sudden stroke, a bad fall, or the slow arrival of dementia can leave an older person unable to say what care they want. When no legal document names who speaks for them, the decision does not simply pass to the nearest relative. It often lands in front of a judge, and the family that expected to help instead spends months and thousands of dollars asking a court for permission. Two documents, signed while a person is still healthy, prevent that outcome and keep both the money and the choices inside the family.
What a living will and a health-care proxy actually do
These two documents together form what most states call an advance directive, and they answer two different questions. A living will records treatment wishes in advance: whether a person wants a ventilator, feeding tube, dialysis, or aggressive resuscitation if there is no reasonable chance of recovery, and when comfort care should replace intervention. It speaks for the patient when the patient cannot, giving doctors written instructions rather than leaving them to guess.
A health-care proxy, also called a durable power of attorney for health care or a health-care agent, does something the living will cannot. It names a specific trusted person to make medical decisions the moment the patient is judged unable to make them. No document can anticipate every scenario, so the proxy fills the gaps, reading the living will’s intent and applying it to the real situation in front of the doctors. The National Institute on Aging describes advance care planning as the process of setting down these wishes so that others are not forced to improvise during a crisis.
The word “durable” carries the legal weight. An ordinary power of attorney can lapse at the very moment it is most needed, when the person who signed it loses mental capacity. A durable directive is written to survive incapacity, which is the entire point, because incapacity is when someone else must step in.

Why medical decisions and money decisions need separate documents
A common and expensive assumption is that one power of attorney covers everything. It does not. A health-care proxy governs treatment, hospitals, and doctors. A financial power of attorney governs bank accounts, bills, insurance claims, and property. They are separate legal instruments, and a person can name the same agent for both or two different people, but each authority must be granted explicitly in its own document.
The distinction matters in practice because the two roles pull in different directions. The health-care agent decides whether to continue a costly treatment; the financial agent decides how to pay for it, keeps the mortgage current, and handles Social Security or pension deposits while the patient is hospitalized. The Consumer Financial Protection Bureau’s guide to managing someone else’s money walks through the financial agent’s duties and the strict obligation to act only in the account holder’s interest, keeping the person’s money entirely separate from the agent’s own.
Without the financial document, a family may find that a health proxy alone cannot touch a bank account to pay the very medical bills the proxy has authorized. Both documents, executed together, close that gap and keep routine finances moving during a long recovery.
The court alternative is guardianship, and it is costly
When an incapacitated adult has signed neither directive, the family’s only route is to petition a court for guardianship, sometimes called conservatorship depending on the state. A judge must formally declare the person incompetent, often after medical evaluations and a hearing, and then appoint a guardian to make decisions under ongoing court supervision. The process takes weeks or months and generates legal fees, filing costs, and sometimes physician and evaluator charges, all paid out of the incapacitated person’s own funds. The National Institute on Aging’s health information encourages putting these directives in place well ahead of a crisis precisely to keep a family off that court path.
The supervision does not end at the appointment. A court-appointed guardian typically files annual accountings and may need judicial approval for major decisions, which adds recurring cost and delay to choices a named agent could have made in an afternoon. Families can also disagree over who should serve, turning a medical emergency into a contested case in which relatives hire competing lawyers. The person at the center, meanwhile, has lost the ability to say who they trusted most.
Timing is the decisive factor, because these documents can only be signed while a person still has the mental capacity to understand them. Once a stroke or advancing dementia has taken that capacity, the window closes permanently, and guardianship becomes the only remaining option. That is why the documents belong in place well before any crisis, reviewed after a major diagnosis, a move to a new state, or the death of a named agent. A directive that names a person who has since died or become unwilling to serve is nearly as troublesome as none at all, and a backup agent guards against that. Put simply, the family that plans keeps the decisions and the money; the family that waits hands both to a courtroom.
