Are Common Seals still required in Hong Kong?

The use of a common seal has traditionally been an important part of corporate governance in many jurisdictions. In Hong Kong, however, the legal and practical role of the common seal has evolved significantly. For modern businesses, particularly SMEs and international groups, understanding whether a common seal is still required is an important aspect of company administration.

What Is a Common Seal

A common seal is a physical stamp used by a company to formally execute documents. Historically, it served as the official signature of the company, providing evidence that a document had been approved and executed in accordance with corporate authority.

The seal would typically be affixed to important legal documents such as contracts, share certificates and deeds, often in the presence of authorised signatories.

The Legal Position in Hong Kong

Under Hong Kong’s current Companies Ordinance, the use of a common seal is no longer mandatory. Companies are free to choose whether to adopt and use a seal as part of their internal governance practices.

This reflects a broader shift towards simplifying corporate administration and aligning with modern business practices. Companies can now execute documents without a seal, provided that the execution is carried out in accordance with the law.

How Documents Are Executed Without a Seal

In the absence of a common seal, a company may execute documents through authorised signatures. Typically, this involves:

• A director signing on behalf of the company

• Two directors signing jointly

• A director and the company secretary signing together

The exact requirements depend on the company’s Articles of Association, which may set out specific rules for execution.

For many businesses, this approach is more practical and efficient, particularly where documents need to be signed quickly or across multiple jurisdictions.

When a Common Seal May Still Be Used

Although not required, some companies continue to use a common seal for internal or external reasons. In certain cases, counterparties, banks or overseas authorities may expect or request documents to be executed under seal.

For example, where a Hong Kong company is dealing with jurisdictions that still place emphasis on sealed documents, maintaining a common seal can help streamline cross-border transactions.

In addition, some organisations prefer to retain a seal as part of their internal control framework, using it for high-value or sensitive documents.

Corporate Governance Considerations

If a company chooses to adopt a common seal, it should implement clear procedures governing its use. This includes defining who has custody of the seal, when it can be used and how its use is authorised and recorded.

Improper or unauthorised use of a common seal can create legal risks, particularly if it results in the execution of documents without proper approval.

Even where a seal is not used, companies should ensure that their execution processes are clearly documented and aligned with their Articles of Association.

Practical Approach for Modern Businesses

For most Hong Kong companies, particularly startups and SMEs, a common seal is no longer necessary. The ability to execute documents through authorised signatures provides sufficient flexibility and aligns with modern digital and international business practices.

However, the decision should be based on the company’s specific needs, including the nature of its operations, the jurisdictions it interacts with and the expectations of its counterparties.

A Flexible Framework

Hong Kong’s approach to common seals reflects its broader commitment to maintaining a business-friendly and adaptable legal environment. By removing the mandatory requirement, the law allows companies to adopt practices that best suit their operational and governance needs.

Whether a company chooses to use a common seal or not, the focus should remain on ensuring that documents are executed properly, authority is clearly established and compliance requirements are met.

For businesses operating in Hong Kong, this flexibility supports efficient administration while maintaining the integrity of corporate processes.
