A UK High Court case involving the alleged theft of 2,323 Bitcoin—worth approximately $172 million—highlights emerging legal challenges around digital asset custody and security that professionals in the blockchain industry should monitor closely.
Case Details and Allegations
UK resident Ping Fai Yuen filed suit against his estranged wife Fun Yung Li and her sister Lai Yung Li, alleging they used covert surveillance to obtain his hardware wallet recovery phrase. According to court filings, the entire balance of Yuen's Trezor wallet was transferred on August 2, 2023, without his authorization. The funds were subsequently distributed across 71 separate addresses before all movement ceased in December 2023.
Court documents indicate that Yuen received a warning from his daughter in July 2023 about his wife's attempts to access his Bitcoin holdings. He installed recording equipment in their home, which later captured audio allegedly showing Li discussing the transfer and saying "take all of it." Additional recordings reportedly captured conversations about camera placement and the location of wallet credentials.
Police arrested Li in 2023 and seized 10 crypto cold wallets during their investigation, but released her after questioning and have not pursued further action without additional evidence. Yuen was separately convicted of assault following a confrontation about the missing funds.
Legal Precedent for Digital Assets
Justice Cotter's March 2025 ruling found Yuen's case has "a strong likelihood of success," describing the evidence as "damning." The judge emphasized that Bitcoin's price volatility necessitates expedited proceedings, as the disputed asset value fluctuates during litigation.
Yuen seeks a proprietary asset preservation injunction to confirm ownership, freeze Li's crypto holdings, and recover either the Bitcoin or equivalent value in British pounds. Li has not presented a defense in the proceedings.
Implications for Blockchain Professionals
This case underscores critical operational security considerations for crypto professionals managing digital assets. Hardware wallet security extends beyond device protection to include safeguarding recovery phrases from physical surveillance threats. The case may establish important precedents for how UK courts handle cryptocurrency ownership disputes and recovery claims, potentially affecting compliance frameworks and custody protocols across the industry.
