The UK High Court recently held a remote hearing in a high-value Bitcoin theft case. The plaintiff, Ping Fai Yuen, accused his estranged wife, Fun Yung Li, of stealing 2,323 Bitcoins stored in a Trezor hardware wallet in 2023. He claimed that she used CCTV footage to secretly record his seed phrase and access password, then transferred the assets in batches. The Bitcoins involved were worth approximately $176 million at the time of reporting.
Plaintiff: Wife and her sister recorded seed phrase and transferred Bitcoin Ping Fai Yuen and Fun Yung Li were originally married. The dispute arose during divorce proceedings. In early July 2023, Ping’s eldest daughter told her father that her mother was planning to take his Bitcoin. Ping then installed recording devices to monitor. Recordings from July 29 and 31 became key evidence, clearly capturing Fun Yung Li and her sister discussing: “The Bitcoin has already been transferred to me,” “Take it first,” “Be careful, he can’t catch us,” “Use a second wallet,” “Find a hacker,” and also mentioning how to avoid banks and police detection for large sums of money.
According to a judgment published by the UK High Court’s King’s Bench Division on March 10, 2026, court documents show that the plaintiff alleges the first defendant, Fun Yung Li, and the second defendant, Lai Yung Li, were involved in exfiltrating the Bitcoin, transferring assets to multiple addresses. The plaintiff claims these Bitcoins were moved to 71 different addresses.
Court documents also include summaries of the recorded conversations, discussing how to handle large sums, avoid detection by banks or police, etc. The judgment mentions that during a search of the defendants’ residence, police found equipment necessary for Bitcoin exfiltration, as described by the judge.
Police previously detained wife, but no further action yet On August 2, 2023, Bitcoin was suddenly transferred out of Ping’s cold wallet, with no subsequent transactions recorded. After Ping reported the theft, police arrested Fun Yung Li on December 23, and searched her residence, recovering 10 cold wallets (including Trezor), 5 seed sets, and several luxury watches. Police successfully unlocked four wallets, three of which were confirmed to belong to Ping. Law enforcement later stated, “Insufficient evidence,” and unless new evidence emerges, no further action will be taken.
The case became more dramatic. In September 2024, Ping, after discovering the Bitcoin had been transferred, had a physical altercation with his wife. He was charged with “causing actual bodily harm” and two counts of common assault, and pleaded guilty on September 13, 2024, serving time. Ping has since moved to Thailand, while Fun Yung Li resides in Hong Kong. The defendant, Fun Yung Li, submitted a brief denial of “lack of knowledge” in court documents and did not attend the hearing, with her lawyer only present as an observer. Her sister, Lai Yung Li, has completely avoided service and has not yet formally responded.
Court ruling: some claims dismissed On March 10, 2026, Judge Cotter issued a ruling (Case No.: KB-2025-004313, Yuen v Li [2026] EWHC 532 (KB)):
Judge: Plaintiff’s success very likely! Early trial recommended In this procedural ruling, Judge Cotter stated that, based on current evidence, the plaintiff’s chances of success “are very high.” The judge noted that the recordings are “highly damaging,” and the police found relevant equipment at the first defendant’s residence, strengthening the plaintiff’s case.
“I believe the plaintiff has demonstrated a very high probability of winning,” Judge Cotter added. “The evidence shows he was warned of the defendant’s intentions, the recordings are conclusive, and during the search of her residence, the necessary equipment for Bitcoin theft was found.”
Paragraph 102 of the judgment states that the first defendant had multiple opportunities to present her case but chose not to. The Bitcoins remain at the addresses they were transferred to, aligning with the plaintiff’s narrative. Based on these factors, the court believes the plaintiff’s chances of success at trial are very high.
