Cap. 501 came into operation on 1 July 1997 and is short, prescriptive and unforgiving. Section 3 requires the instrument to be in the form prescribed by Cap. 501A: Form 1 for a single attorney, Form 2 where two or more are appointed. The donor must either specify the particular property and financial affairs covered or adopt the general categories listed in section 5(3) of the Regulation. An instrument that leaves the authority section blank, or describes the powers loosely, does not take effect as an enduring power at all, as the explanatory notes to the prescribed form state.
Execution is where most EPAs are won or lost. Under section 5(2)(a), the donor signs before both a solicitor and a registered medical practitioner, ideally at one appointment with everyone present. Since the Enduring Powers of Attorney (Amendment) Ordinance 2011, the donor may sign before the doctor and then before the solicitor, provided the second signing falls within 28 days. The doctor certifies mental capacity under section 5(2)(e) and the solicitor certifies under section 5(2)(d), while section 5(2)(aa) disqualifies the attorney, the attorney's spouse and anyone related by blood or marriage to the donor or attorney from either role. The attorney then signs before a witness.
Registration is the second gate. Section 4(2) obliges the attorney to apply to the Registrar of the High Court as soon as he has reason to believe the donor is, or is becoming, mentally incapable, and section 4(3) suspends his authority until registration is complete. The Registrar acts under section 9(2) and the Enduring Powers of Attorney (Registration) Rules (Cap. 4E), and the Judiciary guidance on registering an enduring power of attorney lists the papers the Registry expects. Registration cures nothing: section 9(7) leaves an invalid instrument invalid, and section 16 blocks contracting out.
