LPA and AMD in Singapore

The LPA and the AMD are commonly confused for understandable reasons. Both:

• Address scenarios where the person cannot speak for themselves;
• Involve medical decisions at some level;
• Must be made while the person has capacity and registered with a government body;
• Are often prepared in the same conversation with the same solicitor as part of an estate plan;
• Are described colloquially as "advance directives" or "advance planning" documents.

However, they are governed by different statutes, administered by different government bodies, address different scenarios, and have different formal requirements. Treating them as interchangeable produces gaps in protection. A Singapore resident who has only an LPA is unprotected in the specific scenario the AMD addresses. A resident with only an AMD is unprotected in the much broader scenario the LPA addresses.

The two instruments are summarised as follows:

The remainder of this article walks through each instrument in turn and then explains how they work together as parts of a coordinated plan.

The Lasting Power of Attorney is governed by the Mental Capacity Act 2008 and administered by the Office of the Public Guardian.

The LPA is a pre-emptive appointment by the donor of one or more donees, who will make decisions on the donor's behalf if the donor later loses mental capacity. The donor specifies the scope:

• Personal welfare. Decisions about where the donor lives, day-to-day care, and medical treatment (excluding life-sustaining treatment under a default Form 1).
• Property and affairs. Banking, paying bills, dealing with property, managing investments.

The donor may grant authority in one or both domains. Two forms are available: Form 1 (standard, with default authority) and Form 2 (bespoke, drafted by a solicitor where the donor wishes to depart from defaults).

Key features of the LPA:

• The donor must be at least 21 and have mental capacity at execution;
• A certificate issuer (accredited medical practitioner, solicitor, or psychiatrist) must certify the donor's understanding;
• The donee must be at least 21 and accept the appointment;
• The LPA must be registered with the OPG to take effect;
• The donee's authority engages when the donor loses capacity in the relevant domain;
• The donee has fiduciary duties — best interests, no self-dealing, record-keeping;
• The LPA can be revoked by the donor while capacity is retained;
• The LPA ends automatically on the donor's death.

The LPA covers a broad range of scenarios — anything from temporary incapacity due to an accident to long-term cognitive decline from dementia. It is the principal instrument for incapacity planning in Singapore.

An LPA addresses the universal scenario of capacity loss, which affects a significant proportion of older Singapore residents over time. Even a person who never faces terminal illness in the AMD's sense may face years of incapacity in the LPA's sense.

The Advance Medical Directive is governed by the Advance Medical Directive Act 1996 and administered by the Ministry of Health.

The AMD is a written directive made by the maker, while still capable, instructing medical practitioners that the maker does not wish to have extraordinary life-sustaining treatment in the event that the maker:

• Is suffering from a terminal illness;
• Has been certified as terminally ill by three medical practitioners (including specialists);
• Is unconscious or otherwise unable to exercise rational judgement; and
• Would die within a short period from the terminal illness regardless of extraordinary life-sustaining treatment.

The AMD's scope is deliberately narrow. It does not authorise:

• Euthanasia or assisted dying (which remain unlawful in Singapore);
• Withdrawal of ordinary medical care, nourishment, or palliative comfort;
• Refusal of treatment outside the specific terminal-illness scenario;
• Day-to-day medical decision-making in incapacity;
• Decisions about general living arrangements or care.

Formal execution requires:

• The maker to be at least 21 and have mental capacity;
• The AMD made on the prescribed Ministry of Health form;
• Signature by the maker in the presence of two witnesses;
• One witness must be the maker's own medical practitioner;
• The second witness must be at least 21, of sound mind, and not a beneficiary under the maker's will or insurance policy;
• Registration with the Registrar of Advance Medical Directives at MOH.

The AMD may be revoked by the maker at any time, in any form (including orally), while the maker retains capacity. Once executed, the AMD is confidential — access is restricted to authorised medical practitioners when treating the maker, and the existence of an AMD is not generally disclosed.

The AMD addresses a specific scenario that some people wish to plan for and others do not. It is more personal than the LPA — many people are willing to appoint a donee under an LPA but reluctant to commit in advance to refusing life-sustaining treatment. There is no requirement to make an AMD; it is optional, and many Singapore residents complete their estate planning without one.

The two instruments differ in several important practical respects.

What scenarios they cover

The LPA covers any loss of capacity, whether temporary or permanent, partial or complete, and across the two domains of personal welfare and property and affairs. The AMD covers only the specific terminal-illness-with-imminent-death scenario.

Who acts under each

The LPA appoints a donee — a real person with statutory duties — to make decisions. The donee assesses the donor's best interests at the time of each decision. The AMD does not appoint anyone; it speaks directly to medical practitioners. Once the AMD's prerequisites are satisfied (terminal illness certified by three doctors, etc.), the medical team follows the directive without a substitute decision-maker.

Flexibility versus rigidity

The LPA is flexible. The donee can adjust to changing circumstances, weigh new information, and tailor decisions to the donor's particular situation. The AMD is rigid by design — it is a pre-stated refusal that operates automatically when the prescribed scenario is reached, without case-by-case judgment.

Medical treatment under each

An LPA donee may consent to medical treatment on the donor's behalf in the personal welfare domain, but a Form 1 LPA does not authorise refusal of life-sustaining treatment. A Form 2 LPA may be drafted to grant such authority. The AMD, by contrast, is specifically about refusing extraordinary life-sustaining treatment in a particular scenario.

Engagement triggers

The LPA engages when the donor loses capacity in the relevant domain — a relatively common scenario in older age. The AMD engages only in the narrow terminal-illness scenario with the three-doctor certification — a relatively rare scenario.

Storage and retrieval

The LPA is on the OPG's register, accessible by the donee with appropriate identification. The AMD is on the MOH Registrar's confidential register, accessible only to authorised medical practitioners treating the maker.

Revocation

The LPA may be revoked by the donor in writing while capacity is retained. The AMD may be revoked by the maker at any time and in any form (including orally) while capacity is retained.

The two instruments are complementary, not duplicative. An LPA without an AMD leaves the terminal-illness scenario without explicit pre-stated direction. An AMD without an LPA leaves the broader capacity scenario without a substitute decision-maker. Most Singapore residents who plan thoughtfully do both.

The LPA and AMD operate in distinct but adjacent territory. In some scenarios they may both be relevant, and the way they interact matters.

Scenario: gradual cognitive decline followed by terminal illness

A common life trajectory involves gradual cognitive decline (dementia, for example) over years, followed by terminal illness in later stages. In this trajectory:

• The LPA engages first, when capacity is lost in the property and affairs and personal welfare domains. The donee takes over financial management and day-to-day care decisions.
• If the person later reaches a terminal-illness stage with imminent death, the AMD engages (if one was made). The medical team consults the AMD register; if an AMD is registered, extraordinary life-sustaining treatment is not provided.
• If no AMD was made, decisions about life-sustaining treatment in terminal illness are made by the medical team in consultation with the family, including the LPA donee where the LPA covers personal welfare.

Scenario: sudden incapacity from accident or stroke

A sudden incapacitating event (severe accident, major stroke) immediately engages the LPA's personal welfare authority. The donee makes decisions about treatment, rehabilitation, and ongoing care. If the patient is or becomes terminally ill with imminent death, the AMD may also engage.

Scenario: terminal cancer diagnosis

A terminal cancer diagnosis triggers planning conversations. If the patient still has capacity, they may execute or update an AMD. The LPA may also be relevant for the property and affairs aspects of the deteriorating period. Once the patient enters the unconscious/unable-to-communicate phase, the AMD's prerequisites may be satisfied.

Form 2 LPA with life-sustaining authority

A Form 2 LPA can be drafted to grant the donee authority to refuse life-sustaining treatment. This is one of the bespoke departures from Form 1 defaults. Where a Form 2 LPA grants such authority, the donee may make life-sustaining decisions across a broader range of scenarios than the AMD's narrow terminal-illness scenario.

However, the Form 2 approach places significant responsibility on the donee — to make a decision in real time, weighing the donor's wishes and current medical situation. Many donors prefer the AMD's framework — a pre-stated directive that operates automatically in the defined scenario — to placing the burden on a family member.

The interaction between Form 2 LPAs with life-sustaining authority and AMDs is one of the more nuanced areas of practice. A practising solicitor can advise on the appropriate combination based on the donor's preferences.

For Singapore residents considering both instruments, the following practical considerations recur.

Conversations before drafting

The LPA and AMD both involve sensitive topics — incapacity, terminal illness, end-of-life preferences. Drafting works best when preceded by family conversations. The donor's preferences should be discussed with intended donees (for the LPA), with family members (for both), and where possible with the family's general practitioner (for the AMD).

These conversations are not legal exercises; they are family conversations about values and circumstances. The legal instruments capture the conclusions but do not generate them.

Coordinated execution

Many estate-planning solicitors prepare the LPA and AMD together, either at a single appointment or in close succession. This is efficient — the solicitor has already taken the relevant instructions for both documents — but the AMD requires a separate medical-practitioner witness, which is typically arranged at a follow-up appointment with the donor's GP.

Updating

Both instruments should be reviewed periodically. Major life events (marriage, divorce, death of a donee, change in family circumstances, significant change in health) are appropriate triggers. The LPA can be revoked and replaced; the AMD can be revoked and replaced. Both require updated registrations.

Communicating the existence of the documents

Both the LPA and the AMD require family members to know they exist. An LPA that family members do not know about cannot be retrieved when needed. An AMD that the family GP does not know about may not be consulted in the relevant scenario. Communicate the existence of both documents to the appropriate people, while retaining confidentiality of the contents where desired.

The AMD is genuinely optional

Unlike the LPA, which is universally appropriate for adult Singapore residents, the AMD is a personal choice. Some donors prefer to leave end-of-life decisions to family discussion at the time, rather than committing in advance. There is no right answer; the AMD is appropriate for those who wish to formalise their preferences and inappropriate for those who do not.
