Advance Medical Directive Singapore: How to Register Your AMD and What It Actually Covers

If you are ever in a terminal condition, permanently unconscious, and machines are the only thing keeping you alive, do you want that to continue? Singapore law gives you the right to answer that question in advance — but only if you register an Advance Medical Directive while you still can.

The Advance Medical Directive (AMD) is a legal document governed by the Advance Medical Directive Act 1996. It tells doctors not to use extraordinary life-sustaining treatment to prolong your dying if you are in a terminal condition and cannot communicate your wishes. Without one, doctors are legally obligated to continue all available treatment regardless of prognosis.

What an AMD Does (and Does Not) Cover

An AMD applies only in a very specific scenario: you must be certified terminally ill (death is reasonably expected within a short period even with continued treatment), you must be unconscious or mentally incapacitated, and two doctors — one of whom must be a specialist — must certify both conditions.

What an AMD covers:

• Refusing ventilators, dialysis, CPR, and other extraordinary life-sustaining measures
• Allowing natural death without aggressive mechanical intervention

What an AMD does not cover:

• Palliative care (pain management and comfort care are still provided)
• Routine medical treatment for non-terminal conditions
• Decisions about organ donation (those are governed by HOTA and MTERA separately)
• Day-to-day medical decisions during incapacity (that is what an LPA is for)

The AMD is specifically and narrowly about the end of life. It does not appoint a decision-maker — it records your personal decision about one specific scenario.

AMD vs. LPA: Understanding the Difference

These two documents are frequently confused but cover entirely different situations.

You need both if you want full coverage. An LPA handles a wide range of incapacity decisions; an AMD records your specific wishes about end-of-life treatment that even your LPA Donee cannot override.

Who Can Register an AMD in Singapore?

To register an AMD, you must:

• Be at least 21 years old
• Be of sound mind at the time of signing
• Not be a patient currently in a terminal condition (the Act requires you to register while you are in good health)

There is no cost to register an AMD.

The Registration Process

Step 1: Obtain the AMD form. Download it from the Ministry of Health (MOH) website, or pick up a copy from any polyclinic or restructured hospital.

Step 2: Sign in front of two witnesses. Both witnesses must be over 21 years old and of sound mind. One witness must be a doctor who is not treating you and has no financial interest in your estate. The second witness can be any other eligible adult — a friend, a colleague, or a family member (but not a beneficiary in your will).

Step 3: Submit to the MOH AMD Registry. Return the signed form by post or in person to the AMD Registry at the Ministry of Health. There is no fee.

Once registered, your AMD is stored in the MOH registry and can be retrieved by any treating doctor using your NRIC number. You do not need to carry a physical copy, though many people keep one with their other important documents.

Can You Revoke an AMD?

Yes, at any time and for any reason while you retain mental capacity — simply by informing a doctor verbally, destroying the document, or submitting a written revocation to the MOH AMD Registry. The revocation takes effect immediately.

If you later lose mental capacity, the AMD cannot be revoked, which is why it is important to ensure your wishes are current before any deterioration begins.

Organ Donation: A Separate Decision

Many people conflate the AMD with organ donation, but they are governed by entirely separate legislation.

HOTA (Human Organ Transplant Act): Covers kidneys, heart, liver, and corneas. Singapore operates an opt-out system — all citizens and permanent residents aged 21 and above are automatically included unless they have formally withdrawn consent via the National Organ Transplant Unit. HOTA takes priority over family objections.

MTERA (Medical Therapy, Education and Research Act): Covers any organs, tissues, or the whole body for research or therapy purposes. This is an opt-in scheme — you must proactively pledge.

Your AMD does not affect either scheme. If you have strong views about organ donation, register them separately through the National Organ Transplant Unit.

Who Should Know About Your AMD?

An AMD that no one knows about cannot be acted upon in time. Tell your next-of-kin, your treating doctor, and whoever holds your medical power of attorney (via your LPA) that you have an AMD. The treating hospital will check the MOH registry, but your family's awareness reduces any delay or confusion during an emergency.

If your hospital is notified that you have an AMD, they are legally required to check the registry before proceeding with extraordinary measures. Doctors who comply with a valid AMD are protected from civil or criminal liability under the Act.

AMD as Part of a Complete End-of-Life Plan

The AMD answers one specific question about your end of life. For the full picture — who handles your affairs if you lose capacity, who inherits your assets, what happens to your CPF funds, and what your funeral wishes are — you need a complete end-of-life plan.

The Singapore End-of-Life Planning Guide walks through the AMD process alongside the LPA, will writing, CPF nominations, and funeral pre-planning in a single coordinated framework built specifically for Singapore's legal system.

Registering an AMD takes less than an hour. The harder part is being willing to think through your wishes while there is still time to record them.
