Enduring Power of Attorney in Hong Kong: Cap. 501, Step by Step
An enduring power of attorney — 持久授權書 in Hong Kong — is the document that lets someone you trust keep managing your parent’s money and property after they lose mental capacity. It only works if it is signed while they still understand it, certified by a doctor and a solicitor, and registered with the High Court.

What this page covers
The rest of this page is the detail behind that sentence: what the Enduring Powers of Attorney Ordinance (Cap. 501) requires at signing, the order the signatures must happen in, why registration is not optional, and what an attorney may and may not do with a parent’s money.
What makes a power of attorney “enduring”
Section 3 of Cap. 501 sets three conditions, and all three have to be met. The instrument must be in the prescribed form; it must be executed in the prescribed manner by the donor and the attorney; and it must contain the prescribed explanatory information at the time the donor executes it.
Section 3(3) then closes the door: an instrument that purports to create an enduring power but does not comply cannot take effect as an enduring power at all. There is no partial version — a document that misses one formality is, at best, an ordinary power of attorney that dies when capacity goes.
The signing itself: section 5, in order
This is the part families underestimate, because it is the part that cannot be fixed afterwards. Section 5(2) sets the sequence and the people who must be in the room.
- Your parent signs before a registered medical practitioner and a solicitor — section 5(2)(a)(i).
- The signature before the solicitor happens either at the same sitting as the signature before the doctor, or within 28 days after it — section 5(2)(a)(ii). Miss that window and the execution does not comply.
- Neither the doctor nor the solicitor may be the person being appointed as attorney, the attorney’s spouse, or a person related by blood or marriage to the donor or the attorney — section 5(2)(aa). This is why a family friend who is also the appointed attorney cannot sign as witness.
- The attorney must sign the instrument — section 5(2)(c).
- The solicitor certifies that the donor appeared to be mentally capable in the terms of section 2, that the instrument was signed in the solicitor’s presence, and that the donor acknowledged signing voluntarily — section 5(2)(d).
- The medical practitioner certifies the same matters from their own examination — section 5(2)(e).
- If your parent is physically unable to sign, another person — not the attorney, the attorney’s spouse, the doctor or the solicitor — may sign on their behalf, in their presence and under their direction — section 5(2)(b).
Who can be the attorney
Section 6 restricts the appointment: the attorney must be an individual aged 18 or over who is not bankrupt and not mentally incapable, or a trust corporation. Section 7 rules out an instrument that lets the attorney appoint a substitute or a successor, or delegate trusts under section 27 of the Trustee Ordinance (Cap. 29).
More than one attorney is allowed, but section 15 requires that they be appointed to act jointly, or jointly and severally. Jointly and severally is usually what families want: if one attorney dies or becomes unable to act, the other can carry on without a fresh document nobody can now sign.
Registration is not a formality
An enduring power is designed to survive incapacity, and section 4(1) says exactly that: the power is not revoked by any subsequent mental incapacity of the donor. But section 4(2) and 4(3) attach a condition to using it.
Once the attorney has reason to believe the donor is or is becoming mentally incapable, they must apply to register the instrument as soon as practicable — section 4(2). Until it is registered, the attorney must not do anything under the authority of the power — section 4(3).
There is one narrow exception, in section 4(5): while the application is pending, the attorney may act to maintain the donor or prevent loss to the estate. Paying a care home invoice or an insurance premium can fall inside that; selling a flat usually does not.
Registration is made to the Registrar of the High Court — section 9(1). The Registrar registers the instrument when satisfied that it purports to create an enduring power, that the requirements have been met and that the fee is paid — section 9(2). The original and a certified copy must be lodged — section 9(3) — and the register is open to inspection, with copies available on payment of the fee — section 9(5). Registration does not validate an invalid power — section 9(7) — so a defective signing is not cured by filing it.
What the attorney may do, and what they may not
Section 8(1) is the limit that matters most: an enduring power must not confer any authority other than authority to act in relation to the donor’s property and financial affairs, and it must specify the particular matters, property or affairs covered. Health and care decisions are outside it entirely.
Inside that limit, section 8(3) allows the attorney to act so as to benefit themselves and other people, but only to the extent the donor might be expected to provide for those needs, and to make gifts of a seasonal nature, on a birthday or anniversary, or to a charity the donor supported — and section 8(4) adds that a gift must not be unreasonable having regard to the donor’s estate.
Section 12 turns all of that into duties of a fiduciary nature: to act honestly and with due diligence, to keep proper accounts and records, not to enter a transaction where a conflict of interest would arise with the donor, and not to mix the donor’s property with other property. Section 11 gives the court power, on the application of an interested party, to order accounts, to revoke or vary the power, and to remove the attorney.
“Lasting power of attorney” is the English name, not a Hong Kong document
Families searching for a lasting power of attorney are usually reading about the England and Wales instrument, which replaced the older enduring power there. Hong Kong did not follow that route: what exists here is the enduring power of attorney under Cap. 501, and there is no separate lasting power of attorney in Hong Kong law.
That matters in practice when a parent has lived abroad. An instrument signed in another jurisdiction is not automatically a Hong Kong enduring power, and a bank in Hong Kong is entitled to ask for the local document. If your parent signed something overseas, take advice on whether a Hong Kong instrument is also needed.
When it ends
Section 13(1) lists the ways an enduring power is revoked: the donor revokes it while mentally capable, or after recovering from incapacity where the court confirms the revocation; the attorney becomes bankrupt; a committee is appointed under Part II of the Mental Health Ordinance (Cap. 136) and the court directs revocation; the donor or the attorney dies; or any ground on which a power of attorney is revoked at common law applies.
Section 18(3) adds a safeguard families rarely use and often should: the prescribed form lets the donor nominate people the attorney must notify before applying to register. Section 19 makes clear that a failure to notify does not invalidate the registration, but a court may draw an adverse inference from it.
How to prepare
The document is short; the preparation is the work. Before you book anything, settle these four things:
- Who acts. One attorney or two? If two, decide jointly or jointly and severally, and tell both people what the role involves.
- Which assets are covered. Cap. 501 requires the instrument to specify the matters, property or affairs the attorney may act on, so a current list of bank, brokerage and property assets is the working document for the drafting.
- The doctor and the solicitor. Both must be independent of the attorney and of the family relationship, and both must be present for the signing — with the solicitor signing within 28 days of the doctor.
- Where the registered original lives. After registration the High Court holds the register, but the family still needs to know who holds the certified copy and where the accounts are kept. The emergency documents checklist is the list to file it against.

Where to go next
This page is general information, not legal advice. The instrument itself needs a Hong Kong solicitor, and the doctor’s certification needs an appointment you should make while your parent can still consent to it.
If you are still deciding which document you need, start with what a power of attorney does in Hong Kong. If the question is what happens after a parent dies, that is probate, not an enduring power. And if you want the document kept where a family can find it at 2am, that is what the readiness score checks.
