Letter of Authorisation HK: Cap. 31 and PDPO Rules

It is a private mandate. The document creates actual authority in the common law sense: the principal tells a third party, in writing, that a named representative may act within stated limits, and that third party may then deal with the representative on those terms. No Hong Kong legislation prescribes its form, which is both its strength and its ceiling: no statutory wording to get wrong, no witness requirement, no registration step, and equally no statute forcing anyone to accept it.

Most people confuse it with a power of attorney, and the distinction matters. A power of attorney is a deed. Section 2 of the Powers of Attorney Ordinance (Cap. 31) requires the instrument creating it to be signed and sealed by the donor, or at the donor's direction and in the donor's presence, in which case two witnesses must attest it. Section 7 then supplies a short statutory form conferring authority to do anything the donor could lawfully do through an attorney. An authorisation letter carries no seal, no attestation and no general authority. It delegates a task, not a life. That is why banks take it for delivering documents and refuse it for operating an account.

The letter is a creature of the common law of agency rather than of any ordinance, so its position is defined by the statutes marking its outer edges. The first is Cap. 31: anything that must be done by deed cannot be delegated by letter. The second is land, since under the Conveyancing and Property Ordinance (Cap. 219) and the Land Registration Ordinance (Cap. 128) an assignment, mortgage or legal charge signed by a representative requires a power of attorney executed as a deed. A simple letter is worthless for any dealing that touches title to a Hong Kong property.

Electronic signature is the third boundary, and here the position is better than most assume. Schedule 1 to the Electronic Transactions Ordinance (Cap. 553) removes powers of attorney, statutory declarations and land instruments from the sections giving electronic signatures the same status as wet ink. An ordinary authorisation letter is not on that list, so a scanned version can be legally effective. Counter practice is another matter.

Personal data completes the picture. The letter carries two HKID numbers, so the Personal Data (Privacy) Ordinance (Cap. 486) and the Privacy Commissioner's Code of Practice on the Identity Card Number and other Personal Identifiers bind whoever receives it. No organisation may compel an individual to supply an HKID number unless authorised by law, and the Commissioner has told data users to accept a letter naming the representative instead of taking an HKID card copy. Government practice is more prescriptive: the Immigration Department guidance on authorised representatives collecting certified copies of registration documents requires the representative to be at least 18, to produce their own HKID and to hand over the principal's letter. Where a deed is needed, our general power of attorney under section 7 of Cap. 31 is the correct instrument.

The classic trigger is absence. You are on a business trip, posted to the Mainland or recovering from surgery, and a certificate or a registered mail item has to be collected within a working window. A second is capacity to queue: elderly parents who cannot spend a morning at Immigration Tower, and an adult child who runs the errand with both identity cards. A third is corporate. Staff file at the Companies Registry, collect a business registration certificate or lodge papers with a bank, and the counter wants written authority naming that individual. Where delegation is a standing feature of the business, the paperwork in our business and incorporation templates for Hong Kong companies usually needs updating at the same time.

Domestic helpers and employees produce the fourth scenario. A helper collecting a prescription, a driver collecting vehicle documents or an assistant collecting a transcript each need a mandate tied to a named person, alongside our employment and HR templates under the Employment Ordinance. Two edge cases deserve flagging. Meetings of an owners' corporation fall under the Building Management Ordinance (Cap. 344), which has its own proxy instrument, so a general letter will not count as a proxy vote. And a letter signed by one parent rarely satisfies a consulate where both parents hold custody.

• The identification block sets out the full English and Chinese names of both parties, their HKID or passport numbers and their addresses. Counters cross-check the name against the card presented, so an English name differing by a middle initial from the HKID is the commonest reason a letter is refused at the window.
• The scope of authority is drafted narrowly by default and lists the exact acts permitted: to collect, to sign for receipt, to lodge, to enquire, to pay. Open wording such as authority to handle all matters invites refusal, since the recipient cannot tell where the mandate stops.
• The subject matter reference pins the mandate to a specific file: an application number, a case reference, a policy number or a property address. Without it the letter reads as a standing authority, which few institutions accept.
• The validity period gives a start date and a hard end date, because an undated letter still circulating months after the errand is finished is a real fraud risk.
• The exclusions clause states what the representative may not do: receive funds, vary terms, sign contracts, disclose the documents onward. It persuades a cautious officer that the mandate has been thought through.
• The signature and revocation block provides for the principal's signature, an optional witness line and a statement that authority ends on written notice, on the expiry date or on death, whichever is earlier.

Government departments are the most predictable and the most formalistic. Immigration, the Transport Department, the Companies Registry and the Inland Revenue Department work from published requirements: the representative must usually be 18 or over, must produce their own HKID, and the letter must state the names and HKID numbers of both parties. Several forms, including those under the Registration of Persons Regulations (Cap. 177A), want the authorisation attached when the application is filed.

Banks and financial institutions are the hardest audience. A letter gets documents delivered and a statement collected at branch discretion, but it will not open, operate or close an account. Banks register powers of attorney and want the original or a solicitor-certified copy. They also carry a duty under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (Cap. 615) to verify anyone purporting to act for a customer, so the representative faces identity checks in their own right.

Hospitals and clinics treat the letter as a data access authorisation. Requests for medical records engage section 18 of Cap. 486, and the records office checks that it identifies the patient, the records sought and the person collecting them. Verbal authority from a relative is not enough. Schools and universities often publish their own transcript form, and where they do, use theirs and attach your letter as support.

Property managers, couriers and logistics operators accept a letter readily for parcels, keys and access, though house rules may add a registration step. Where the arrangement is a tenancy, the mandate should match our Hong Kong tenancy and property templates, particularly on who may hold keys.

You begin by choosing the purpose, because the purpose drives everything else. Selecting collection of a government document produces a tighter scope clause and prompts you for a file reference, while a banking errand adds language on identity verification and on the absence of authority over funds. The form then takes the principal's details, then the representative's, and asks for names in English and Chinese so the wording matches the identity documents produced.

The scope screen is where the drafting happens. You tick the acts you are granting, the form assembles them into one operative sentence, and a standard exclusions paragraph follows that you can extend. Next comes the validity window, with a suggested end date tied to the errand. The final screen handles signature and layout, including whether you want a witness line and a bilingual version. The result downloads as an editable Word file and a print-ready PDF. The rest of our personal and family document templates for Hong Kong follow the same guided structure.

The most frequent failure is scope drift. A mandate written to let someone collect a certificate gets reused three months later to lodge a different application, the recipient reads the original wording, and the errand dies at the counter. Close behind is the missing expiry date, which turns a one-off errand into an open authority the principal cannot easily withdraw. Third is the name mismatch: the letter says Chan Tai Man, the HKID says Chan Tai-man, and a cautious officer refuses to release anything on that basis alone. Where the identity documents disagree, reproduce the HKID spelling exactly and note the alternative in brackets.

Two further mistakes carry legal exposure. Granting authority over money with no exclusions leaves the principal open to acts they never contemplated, and misuse by a representative who exceeds the mandate can amount to fraud under section 16A of the Theft Ordinance (Cap. 210). Altering the document after signature, even to correct a date, risks the forgery provisions in Part IX of the Crimes Ordinance (Cap. 200). Never backdate an authorisation and never let a representative fill in a blank scope. Reissue instead.
