Anthony Siu & Co

Hong Kong (HK)–a special administrative region of the People’s Republic of China (PRC)–has a distinct and independent legal system under the ‘one country, two systems’ policy.

Although HK retains numerous distinctions from Mainland China, one factor that most extensively impacts business operations and the resolution of cross-border disputes in the locale is its unique legal system.

Civil judgements or arbitrations awards issued in HK are not automatically enforceable in Mainland China’s jurisdiction and vice-versa as they can only be recognized on condition that certain requirements under the bilateral agreements on Reciprocal Recognition and Enforcement are met, making the whole legal framework complicated to navigate.

In the middle of this tangle of cross-border regulations stands the calming presence of the multi-jurisdictional and multinational litigation specialist, Anthony Siu & Co. The Hong Kong-based law firm specializes in cross-border contentious practices and provides businesses with quick resolutions in an efficient and effective manner.

Anthony Siu & Co. offers client-centric legal services for general corporate, commercial, and capital market affairs. It counsels on routine business operations, M&A, cross-border trade spanning HK, Mainland China and abroad, and secretarial duties.

“Our team of cross-border contentious practice experts, holding licenses to practice law across many countries, utilizes its understanding of different jurisdictions to seamlessly analyze complex legal issues and provide befitting legal advices,” says Mr Anthony Siu, principal and founder of Anthony Siu & Co.
