Are Hong Kong Companies Really a "Firewall"? — Piercing the Corporate Veil Through a Cross-Border Trade Secrets Dispute

2026/10/14

Many business owners believe that by incorporating a company offshore and placing their business and assets into it, they can insulate themselves from personal liability. However, a cross-border trade secrets dispute demonstrates that where a company is used as an instrument of wrongdoing, a court may well "pierce the corporate veil" and hold the shareholder behind it directly liable.

Case Overview

A German enterprise established a wholly-owned subsidiary in Shanghai, which had long been engaged in the automatic control equipment business. Around the time its sales manager left the company, that individual — using customer information, quotation proposals and profit data in his possession — assisted a one-person company incorporated in Hong Kong and held by his relative in entering into procurement contracts with mainland customers, with the assistance of the company he had newly joined in performing those contracts. The Shanghai company accordingly sued the manager, the Hong Kong company and related individuals, asserting infringement of trade secrets and unfair competition.

One of the issues in dispute was whether the sole shareholder of the Hong Kong company should bear joint and several liability for the company's debts. Because Hong Kong is a common law jurisdiction and its statute law does not expressly provide for "piercing the corporate veil," the court commissioned a professional institution to ascertain Hong Kong case law, and ultimately found that the shareholder had used the company's separate legal personality to engage in unlawful conduct and evade legal liability, with clear subjective malice, and ordered him to bear joint and several liability.

Dispute and Unresolved Questions

The tension in this case lies in the following: the separate legal personality of a company is the cornerstone of market transactions, but where a shareholder abuses that institution and turns the company into a "white glove," should the law still protect his limited liability? The court's answer was unequivocal: no. Although Hong Kong case law has not been codified, by examining factors such as actual operations, transfers of assets and subjective intent, the court may deny the company's separate legal personality and pursue the shareholder directly.

Lawyer's View

"Piercing the corporate veil" is not unique to the mainland; it exists equally in common law systems, though the conditions for its application are strict. In cross-border disputes, a court must first ascertain the foreign law and then determine the matter in light of the case law rules. For businesses, when dealing with a Hong Kong company, one should not look only at the certificate of incorporation, but should also verify the shareholding structure, the actual controller, the substance of operations and the whereabouts of assets. For shareholders of Hong Kong companies, do not use the company's separate status to evade debts, transfer assets or engage in infringement, otherwise you may face joint and several liability.

Lawyer's Recommendations

1.Due diligence before transactions: Verify the Hong Kong company's shareholder background, actual controller, office address and business turnover, and assess whether it has genuine operational capacity.

2.Keep a documentary record of contracts: Clearly stipulate the governing law and dispute resolution method, and retain communication records, payment vouchers and evidence of performance.

3.Infringement early warning: If trade secrets are discovered to have been leaked or customers to have been "poached," promptly secure evidence and apply for conduct preservation to prevent further loss.

4.Cross-border enforcement of rights: Hong Kong-related cases require ascertainment of Hong Kong law; it is advisable to engage professional lawyers as early as possible and formulate a plan for the ascertainment and application of foreign law.

5.Compliant operation: Shareholders of Hong Kong companies should standardize their finances and avoid commingling, so as to prevent the company from being found to be an instrument of wrongdoing.

Role of Lawyers

In cross-border commercial disputes, lawyers are not merely litigation agents, but also the organizers of legal ascertainment, strategy design and risk prevention and control. From determining whether "piercing the corporate veil" applies, to commissioning foreign-law ascertainment institutions and sorting out the case law rules, and further to securing evidence and preserving assets, the involvement of professional lawyers often determines the course of a case. For businesses, prior compliance review and ongoing legal support are far more effective than pursuing liability after the fact.

Conclusion

A company's separate legal personality is not a "shield" for unlawful conduct. In cross-border transactions, respecting the law and operating in a compliant manner is the true risk firewall. If you encounter a related dispute, it is advisable to consult a professional lawyer as early as possible and protect your rights in accordance with the law.
