Notarisation for International Use: Hong Kong Documents for the UAE, Singapore, and Other Key Jurisdictions

Introduction

Individuals and businesses in Hong Kong frequently need to use official documents abroad – for property transactions, company incorporation, visa applications, court proceedings, or commercial contracts. The process for authenticating Hong Kong documents for overseas use varies significantly depending on the destination country and the type of document involved.

This guide explains the main authentication routes available to Hong Kong document holders – apostille certification and consular legalisation – and sets out the specific requirements for some of the most commonly encountered destination jurisdictions.

Understanding the Two Authentication Routes

Route 1: Apostille (Hague Convention Countries)

The Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents (the “Hague Apostille Convention”) simplifies the authentication of public documents between member countries. Under the Convention, a document issued in one member country need only be apostilled by the designated competent authority of the issuing country – no further consular legalisation is required.

Hong Kong acceded to the Convention in May 2024 (with China’s extension of the Convention to Hong Kong). The designated competent authority in Hong Kong for apostille certification is the Government Records Service (for government-issued documents) and Notarial certificates from a Hong Kong Notary Public (for privately-executed documents authenticated by a notary).

Common apostille-accepting jurisdictions include the United Kingdom, European Union member states, Australia, New Zealand, India, and many others – over 120 countries in total as of 2025.

Route 2: Notarisation + Consular Legalisation (Non-Convention Countries)

For countries that are not members of the Hague Apostille Convention, the traditional legalisation chain applies:

1. Notarisation by a Hong Kong Notary Public – the notary witnesses the document, verifies the signatory’s identity, and affixes their official seal and signature;
2. Authentication by the Hong Kong High Court (for certain documents) or Government Records Service;
3. Consular legalisation by the relevant country’s consulate in Hong Kong – the consulate verifies the notary’s or authenticating authority’s seal and signature.

The consular legalisation step requires attendance at the relevant consulate, payment of consular fees, and varying processing times.

Country-Specific Requirements

Mainland China

Mainland China is not an Hague Apostille Convention member. The authentication process for Hong Kong documents for use in Mainland China follows a specific bilateral route:

• Civil documents (birth certificates, marriage certificates, powers of attorney, company documents) – must be notarised by a Hong Kong Notary Public (who is also recognised as a “Notary in China” status or whose notarial certificates are accepted by Chinese authorities), then authenticated by the China Legal Service (HK) Ltd, the official designated body for authenticating Hong Kong notarial certificates for Mainland use;
• Corporate documents (board resolutions, articles of association) – same authentication route: notarise → China Legal Service authentication;
• Court orders – special bilateral arrangements apply for recognition of Hong Kong judgments in Mainland China and vice versa, which do not require the standard notarial route.

Note: China Legal Service (HK) Ltd is the only body authorised to authenticate documents for Mainland use. Using other authentication agents is invalid.

United Arab Emirates (UAE)

The UAE joined the Hague Apostille Convention in 2021, meaning documents from member countries (including Hong Kong from 2024) can now use the apostille route for UAE use.

For Hong Kong documents intended for the UAE, the recommended route is:

• Notarisation by a Hong Kong Notary Public;
• Apostille certification by the Hong Kong Government Records Service (for official documents) or confirmation of the notary’s status (for notarially-certified documents);
• Some UAE authorities (particularly in Dubai, Abu Dhabi ADGM, or DIFC contexts) may have additional requirements, including Arabic translation by a certified translator and attestation by UAE authorities upon arrival.

Parties should verify current requirements with the specific UAE authority or institution (court, Land Department, Ministry of Foreign Affairs) that will be receiving the documents, as requirements vary.

Singapore

Singapore is a member of the Hague Apostille Convention. Hong Kong documents for use in Singapore may be authenticated via:

• Apostille – obtained from the relevant Hong Kong authority after notarisation;
• Singapore’s government agencies (ACRA, courts, MOM) and private institutions typically accept apostilled documents from Hong Kong without further legalisation.

For company registration and corporate documentation in Singapore, specific document requirements apply (e.g., certified true copy of Hong Kong company’s Certificate of Incorporation, Memorandum and Articles, and director’s list – all apostilled).

United Kingdom

The UK is a member of the Hague Apostille Convention. Apostilled Hong Kong documents are generally accepted in the UK for court proceedings, property transactions, and company matters. The UK Foreign, Commonwealth & Development Office (FCDO) no longer issues apostilles for Hong Kong documents; the Hong Kong-based apostille authority issues the certification.

United States of America

The United States joined the Hague Apostille Convention in 1981 but its implementation varies by state. Federal documents are apostilled by the U.S. Department of State; state-level documents are apostilled by the relevant state authority. For Hong Kong documents intended for U.S. use:

• Documents may be apostilled in Hong Kong and used in U.S. federal courts and agencies;
• For use in specific U.S. states, the document’s acceptability depends on the receiving state’s requirements;
• Some U.S. entities (banks, notarial bodies) may require additional certification or translation into English (which Hong Kong documents already are).

Australia and New Zealand

Both Australia and New Zealand are Hague Apostille Convention members and routinely accept apostilled Hong Kong documents. Common use cases include migration applications (apostilled birth/marriage certificates, police clearance letters), property transactions, and court proceedings.

India

India is a Hague Convention member. Apostilled Hong Kong documents are accepted for various purposes in India, including property transactions, court filings, and business registration. Documents in Chinese must be accompanied by a certified English translation.

Japan and South Korea

Japan and South Korea are Hague Convention members. Apostilled documents from Hong Kong are accepted. For use in Japanese courts or official proceedings, translation into Japanese by a certified translator is typically required.

Non-Convention Countries (Selected)

For use in Saudi Arabia, Kuwait, Qatar (before their Convention accession), and other Gulf states that had not yet joined the Convention, the traditional legalisation chain (notarise → authenticate → consular legalise) applied. Many Gulf states have since joined or are in the process of joining the Convention; parties should verify current status.

For use in Vietnam, Indonesia, and the Philippines, consular legalisation through the relevant consulate in Hong Kong remains required as these jurisdictions are not Convention members.

Types of Documents Commonly Notarised for Overseas Use

• Powers of attorney – authorising an agent to act on the principal’s behalf in the destination country (e.g., to manage property, sign contracts);
• Company documents – certificates of incorporation, memorandum and articles, board resolutions, certificates of incumbency;
• Personal documents – birth certificates, marriage certificates, death certificates, educational certificates, passports (copies);
• Affidavits and statutory declarations – sworn statements for overseas courts or government authorities;
• Commercial contracts – where execution before a notary is required by the destination country.

Practical Tips

• Check requirements early – authentication requirements change; verify current requirements with the destination authority or your Hong Kong notary before commencing the process;
• Allow sufficient time – apostille and legalisation processes take days to weeks; consular appointments may have long waiting times;
• Translation – documents in Chinese require certified translation for many countries; instruct a certified translator in the destination country’s language;
• Multiple originals – if you need authenticated copies in multiple countries, obtain multiple notarised originals at the outset to avoid repeat fees and delays;
• Corporate signatories – for company documents, ensure the appropriate authorised signatory (director, company secretary) executes the document in the notary’s presence.
