Short History
The idea of directing your own medical care in advance is younger than it seems. The term living will was coined by the American lawyer Luis Kutner in 1969: he carried the logic of a will over to the case where a person is still alive but can no longer express their wishes. The first statute to recognise it was California's Natural Death Act of 1976 (in force from 1977), which established a patient's right to refuse life-sustaining treatment. By 1990 the idea had reached the federal level — the Patient Self-Determination Act required US hospitals working with Medicare and Medicaid to inform patients of their right to leave an advance directive.
The property side developed in parallel. An ordinary common-law power of attorney lapsed at exactly the moment it was needed most — when the principal lost capacity. That flaw was closed by the durable power of attorney in the United States and the enduring power of attorney in England: both keep running after incapacity sets in. In England and Wales the regime was rewritten by the Mental Capacity Act 2005 — the enduring power was replaced by the lasting power of attorney, with mandatory registration.
Concept
Estate planning thinks about death, but there is a scenario no less acute — incapacity: the owner is alive but cannot make decisions after a stroke, an accident, or an illness. Without documents prepared in advance, the assets and the person's own life fall into a legal vacuum.
Capacity ebbs away in different ways. It can vanish suddenly — a stroke, an accident, a coma — or fade over years with dementia, when a person still signs papers but no longer fully grasps the consequences. The law therefore assesses a specific decision at a specific moment: you can keep the capacity to handle everyday spending and lose it for selling a company at the same time. The documents are prepared in advance for a simple reason: once incapacity has set in, they can no longer be executed lawfully.
Power of Attorney
A long-term power of attorney (durable in the United States, lasting in England) names in advance the person who will manage property and affairs if the owner loses capacity. Without one, the family is left with the court: appointing a guardian or deputy is slow, public, and rarely ends with the person the owner would have chosen. The English lasting power of attorney also takes effect only after registration with the Office of the Public Guardian, so it cannot be arranged retroactively once capacity is already lost.
The English regime splits the instrument into two separate lasting powers of attorney: one for property and financial affairs — money, accounts, real estate, the other for health and welfare — treatment, care, place of residence. The property one can be put to use immediately after registration, while the principal is still capable; the medical one comes into play only when the principal can no longer decide. In the United States a power of attorney may be immediate (effective from signing) or springing (triggered by the onset of incapacity); the springing form has a downside — the moment of "triggering" has to be confirmed by a medical opinion, and some states have abandoned it.
Medical Directives
Here two different documents are at work. A living will (an advance decision about treatment) records the person's own wishes — for example, a refusal of artificial life support in a hopeless situation. A healthcare proxy (a power of attorney for medical decisions) appoints the person who will make the decisions the directive does not provide for. Together they spare the family both blind guesswork and quarrels at the bedside. In the United States both documents are grouped under the common name advance directive.
The cost of a missing document is measurable. The American Terri Schiavo fell into a persistent vegetative state in 1990 without leaving any written instructions; the dispute between her husband and her parents over withdrawing support dragged through the courts until 2005 and reached Congress. Cases like this are what pushed legislators: the Patient Self-Determination Act required that patients be asked whether they have an advance directive on admission to hospital.
Organ Donation
Organ donation is the decision that takes effect past the threshold of capacity, when the person can no longer say anything. Its modern framework took shape quickly and almost at the same time as the idea of the living will. In December 1967 Christiaan Barnard performed the first human heart transplant; by 1968 a Harvard committee had described "irreversible coma" and introduced the concept of brain death, and that same year produced the Uniform Anatomical Gift Act — the legal footing for consenting to donation during one's lifetime. By 1981 the Uniform Determination of Death Act had established that death means the irreversible cessation of either the heart and lungs or of the entire brain, including the brainstem.
From there countries diverged on how to seek consent. Opt-in — the United States, Germany — treats as a donor whoever signed up themselves: through a register or a mark on a driving licence. Opt-out, also known as presumed consent, treats as a donor everyone who has not expressly refused. More and more jurisdictions are taking this path: Spain since 1979, Wales since 2015, England since May 2020 (Max and Keira's Law), Scotland since 2021.
The law by itself decides little. Spain holds the world lead — about 50 donors per million, twice the US and British rate — and the reason is the "Spanish model": transplant coordinators in every hospital and patient work with the family. Presumed consent here is only the backdrop; it is the infrastructure that delivers. Russia, incidentally, is also a presumed-consent country: a 1992 law treats as a donor any adult who did not declare a refusal during their lifetime — orally before witnesses or in writing; for minors the opposite presumption applies, and parental consent is required.
Cross-Border Recognition
The patchwork of national regimes is smoothed by the Hague Convention of 13 January 2000 on the International Protection of Adults. It sets which court has jurisdiction and which law applies when an incapacitated person has assets and interests in different countries, and it gives effect in one contracting state to a power of representation issued in another. The Convention has been in force since 1 January 2009, but the circle of participants is still narrow — some EU countries and, in the United Kingdom, only Scotland (England and Wales signed it but did not ratify). Outside that circle, manual legalisation remains: an apostille, a sworn translation, sometimes an opinion from a local lawyer.
Connection to Estate Planning
A complete plan covers three states of the owner: capacity (ordinary management), incapacity (power of attorney and directives), and death (will, foundation, trust). The middle link drops out more often than the others — and then the carefully assembled structure hangs in the air. It hits business hardest: if decisions rest on one person, their sudden incapacity halts the company no less than death would, which is why a power of attorney is tied to succession mechanisms.
When assets are held through a holding company, a foundation, or a trust, part of the problem is removed by the level of management itself: directors and the protector keep acting regardless of the founder's condition, and in a Private Trust Company the family's role can be divided among several people in advance. The power of attorney then covers the owner's personal perimeter — direct accounts, real estate, a vote at a meeting — while the structure holds the rest. These instruments are coordinated with one another so that the attorney, the protector, and the executor do not pull in different directions; questions of business succession and the family holding are resolved in the same document.
Q/A
I have a will — does it not cover incapacity?
No: a will works only after death. The gap is closed by two other documents — a long-term power of attorney over property and affairs (durable in the United States, lasting in England) and medical directives for treatment. Without them the family is left with the court, and appointing a guardian or deputy is slow, public and rarely ends with the person the owner would have chosen.
My father is no longer fully lucid — can he still grant a power of attorney?
As a rule, no: once capacity is lost the document can no longer be executed lawfully, and an English lasting power of attorney additionally takes effect only after registration with the Office of the Public Guardian, so it cannot be arranged retroactively. The law assesses a specific decision at a specific moment: capacity for everyday spending does not amount to capacity to grant a power over the sale of a company.
Does an English lasting power of attorney take effect as soon as it is signed?
No — only once it is registered with the Office of the Public Guardian, and what follows depends on the type. The property and financial affairs LPA can be used straight after registration, with the donor's permission, while the donor still has capacity; the health and welfare LPA comes into play only when the donor can no longer decide.
Will a power of attorney from one country be accepted by a bank or hospital abroad?
Only under the law of the country where it is presented. The 2000 Hague Convention on the International Protection of Adults gives effect in one contracting state to a power of representation issued in another, but the circle is narrow: it has been in force since 1 January 2009, and the UK ratification binds only Scotland — England and Wales never ratified. Outside it, an apostille and a sworn translation remain.
Could a living will refusing life support get in the way of organ donation?
It can: retrieval sometimes requires the body to be kept on machines, while the directive instructs that they be switched off. The two scenarios are therefore separated in the document itself, in advance. Wishes on donation are recorded alongside the medical directives — in an opt-in jurisdiction enrolling the person as a donor, in an opt-out jurisdiction recording a refusal.
