Disputes, Investigations & Enforcement

Commercial litigation, fraud and cryptocurrency asset recovery, POCA and Account Freezing Orders, and the enforcement of Chinese judgments and arbitral awards in England.

Immigration, Nationality & Appeals

Complex applications, refusals, appeals and judicial review — including R (Wang) v SSHD [2023] UKSC 21, acting for over 100 investors.

Family, Wealth & Property

Cross-border divorce, financial remedies, and disputes over family money in English property — TOLATA, trusts and WeChat-evidenced contributions.

Commercial, Corporate & Employment

Establishing and operating a business in the UK: companies, contracts, employment and sponsor licences — before problems become disputes.

Built for UK–China matters

Half our work crosses the UK–China line: enforcing and resisting claims where the money, evidence or parties are in China or Hong Kong; bringing Chinese businesses into the UK; and protecting Chinese-speaking families' assets in England. We run these matters in-house, in the client's language, without translation intermediaries.
