A Certificate of Incumbency (COI) is a corporate document that confirms the current directors, shareholders, officers, and registered details of a company at a specific date. It is one of the key documents required when registering and operating a Hong Kong company in an international context. It is not issued by a government authority. It is prepared and certified by a licensed service provider (company secretary or TCSP) on behalf of the company.
Banks, law firms, and counterparties request a Certificate of Incumbency when they need to verify who controls a company before completing a transaction. It is one of the most commonly required documents for international business dealings involving a Hong Kong company.
Highlights of this article
- A Certificate of Incumbency confirms the company's current directors, shareholders, company secretary, registered address, and incorporation details as of a specific date.
- It is a private document (not filed with the government) but is widely accepted by banks, law firms, and counterparties for KYC and due diligence purposes.
- Preparation typically takes 1 to 3 business days. Cost ranges from HKD 1,500 to HKD 3,000 from a licensed service provider.
- For official public records, the Companies Registry's Company Particulars Report (CPR) is an alternative at HKD 22 per report.
- If the COI is for use overseas, it may require notarisation or apostille, which adds time and cost.
What Is a Certificate of Incumbency?
A Certificate of Incumbency is a statement issued by the company's registered agent, company secretary, or licensed TCSP confirming the company's current status and key corporate details. It is signed by the secretary and typically sealed or certified with the company chop.
The document is prepared as of a specific date (the "incumbency date"). It reflects the company's statutory records at that moment, not historical changes or future planned changes.
Alternative names for the same document:
- Certificate of Good Standing (in some jurisdictions)
- Certificate of Officers
- Incumbency Certificate
- Secretary's Certificate
Note: In Hong Kong, a "Certificate of Good Standing" is a separate document issued by the Companies Registry itself, confirming that the company has not been wound up or struck off. These are distinct from the Certificate of Incumbency prepared by a service provider.
What Does a Certificate of Incumbency Include?
A standard Hong Kong Certificate of Incumbency contains:
| Section | Content |
|---|---|
| Company name | Full registered name in English and/or Chinese |
| Company Registration Number (CRN) | From the Certificate of Incorporation |
| Business Registration Number (BRN) | From the Business Registration Certificate |
| Date of incorporation | As shown on the Certificate of Incorporation |
| Registered office address | Current registered address on public record |
| Directors | Full names, nationalities, and addresses of all current directors |
| Shareholders | Names and shareholdings of all current shareholders |
| Company secretary | Name of current company secretary |
| Incumbency date | The date as of which the information is certified |
| Signature and seal | Signed by the company secretary, sealed with company chop if applicable |
The COI does not replace the company's statutory registers. It summarises them as of a specific date.
When Do You Need a Certificate of Incumbency?
Opening a Corporate Bank Account
Most banks require a COI during the account opening process for a Hong Kong company. The bank's compliance team uses it to verify the beneficial owners, directors, and authorised signatories. Traditional banks (HSBC, DBS, Hang Seng) require it as part of their KYC documentation. Digital banks may accept the Certificate of Incorporation and Business Registration Certificate instead.
International Transactions and Contracts
When a Hong Kong company enters into a significant commercial contract with an overseas counterparty, the foreign party often requests a COI to confirm that the person signing the contract is authorised to do so and that the company is in good standing.
Loan Applications and Trade Finance
Lenders, trade finance providers, and letter of credit issuers routinely require a COI to verify the borrowing entity's current directors and shareholders before approving credit facilities.
Mergers, Acquisitions, and Due Diligence
In M&A transactions, the buyer's legal counsel requests a COI from the target company as part of the legal due diligence package. It confirms the corporate structure at the point of deal signing or closing.
Regulatory and Licensing Applications
Some Hong Kong regulatory applications (TCSP licence, money service operator licence) and government procurement processes require a COI demonstrating the company's current structure and good standing.
Who Can Issue a Certificate of Incumbency?
A Certificate of Incumbency can be issued by:
- The company's company secretary (if an individual ordinarily resident in Hong Kong)
- A licensed TCSP (Trust and Corporate Service Provider, licensed by the Companies Registry)
- The company's board of directors, by board resolution
In practice, banks and counterparties prefer a COI issued by a licensed TCSP or professional firm, as it carries greater credibility and professional indemnity backing. A self-issued COI (where a director certifies information about their own company) is accepted in some contexts but may face additional scrutiny.
Air Corporate, as a licensed TCSP, issues Certificates of Incumbency for current clients as part of the company secretary service.
How to Obtain a Certificate of Incumbency in Hong Kong
Step 1: Contact your company secretary or service provider
Request the COI from your registered company secretary or TCSP. Provide the purpose for which the document is required, as this affects what the document needs to cover (e.g., a bank may have a specific format requirement).
Step 2: Verify current company records
The service provider verifies the current state of the company's statutory registers: directors, shareholders, registered address, and company secretary. Any recent changes that have not yet been filed with the Companies Registry should be noted or updated before the COI is prepared.
Step 3: Prepare and certify the document
The TCSP prepares the COI document, has it signed by the authorised secretary, and affixes the company chop. Some requestors require it to be on the secretary's letterhead; others specify a notarial format.
Step 4: Notarisation and apostille (if required for overseas use)
If the COI is required by a foreign bank or counterparty in a country that is not comfortable with a certified company secretary document alone, you may need:
- Notarisation: A Hong Kong solicitor or notary public verifies and notarises the document. Cost: HKD 2,000 to HKD 4,000.
- Apostille: For use in countries that are signatories to the Hague Convention, an apostille stamp is attached by the High Court of Hong Kong. Cost: HKD 1,000 to HKD 2,000 per document.
Not all countries require an apostille. Check with your counterparty or local counsel before incurring this additional step.
How Long Does It Take and What Does It Cost?
| Service | Timeline | Typical Cost |
|---|---|---|
| Standard COI preparation | 1 to 3 business days | HKD 1,500 to HKD 3,000 |
| Express COI preparation | Same day | HKD 800 to HKD 1,500 additional |
| Notarisation | 2 to 5 business days | HKD 2,000 to HKD 4,000 |
| Apostille (High Court) | 3 to 7 business days | HKD 1,000 to HKD 2,000 |
| International courier | 3 to 5 business days | HKD 300 to HKD 800 |
Costs vary by service provider. For Air Corporate clients, COI preparation is available as an add-on to the company secretary service. The Expert incorporation package includes a Certificate of Incumbency as standard.

The Company Particulars Report: A Government Alternative
The Company Particulars Report (CPR) is an official document issued by the Companies Registry's ICRIS portal. It provides current public records on the company including registration details, directors, shareholders, and registered address.
| Feature | Certificate of Incumbency | Company Particulars Report |
|---|---|---|
| Issued by | Company secretary / TCSP | Companies Registry (government) |
| Cost | HKD 1,500 to HKD 3,000 | HKD 22 |
| Speed | 1 to 3 days | Instant (online) |
| Level of detail | Comprehensive (all registers) | Public record only |
| Private document | Yes | No (publicly accessible) |
| Bank acceptance | Widely accepted | Accepted by many banks |
For many purposes, the CPR at HKD 22 is a practical and cost-effective alternative to a COI. Banks, especially digital banks and fintechs, often accept the CPR in lieu of a full COI. Check with your bank before commissioning a COI.
When to Update Your Certificate of Incumbency
A COI is valid only as of the incumbency date printed on it. Banks and counterparties typically require a COI dated within 3 to 6 months of the request. If your company has had changes in directors, shareholders, or address since the last COI was issued, you must obtain a new one reflecting the current records.
Common triggers for a new COI:
- Change of director (appointment or resignation)
- Change of shareholders or share transfer
- Change of registered address
- Change of company secretary
- Any change that affects the company's authorised signatories
After any material corporate change, update the relevant statutory registers and file the required forms with the Companies Registry before requesting a new COI. The COI must reflect the filed, current position. For a full breakdown of what statutory registers the company must maintain, see company secretary in Hong Kong.
