Background
The fourth claimant, Wo Wei Dong (C4), is a PRC national who claims to own and operate the Huiyin Group, a network of companies incorporated across the PRC, Cayman Islands, British Virgin Islands, and Singapore. He alleges that his wife Sun Hongmin (D2), daughter Wo Qi (D1), and son Wo Quan, also known as James Wo (D12), conspired to misappropriate his assets totalling approximately US$600 million. Those assets fall into two broad categories: “Digital Assets” — primarily cryptocurrencies and blockchain-based tokens held in exchange accounts (Binance, OKX, Gate.io) that C4 entrusted to D1 to manage — and “Non-Digital Assets”, comprising shares in several foreign companies held by D2 and D12 that C4 contends they hold on express oral trust for him.
The dispute crystallised in December 2023 when D1 allegedly locked C4 out of the Binance and OKX accounts and transferred all cryptocurrency holdings to wallets controlled by D2’s group. C4 filed Originating Claim No 107 of 2024 (OC 107) in the Singapore High Court in February 2024. The defendants’ pleaded case is that D2 is the sole beneficial owner of the disputed digital and corporate assets, which were managed under her “Digital Finance Group” brand by D12 as CEO; they deny every oral trust agreement alleged by C4.
After substantially engaging with the merits — filing a defence, opposing amendment applications, and ultimately withdrawing an appeal — the defendants changed solicitors in May 2025 and pivoted to a jurisdictional strategy. D1, D2 and various corporate defendants filed Defences (Jurisdiction) and three sets of stay applications (SUM 1750, SUM 1751, and SUM 2292). They sought either a stay on the ground that the PRC is the natural forum (forum non conveniens), or alternatively a case management stay pending divorce proceedings commenced by D2 against C4 before the Shanghai Jing’an District People’s Court.
The Court’s Holding
Kristy Tan J dismissed all three Stay Applications. On the forum non conveniens ground, the court considered whether the defendants had waived any right to object to Singapore’s jurisdiction and to seek a stay on natural forum grounds by reason of their prior substantive participation in OC 107 — including filing a defence on the merits, opposing amendment applications, and withdrawing their own merits-stage appeal. The court also addressed the legal question of whether an applicant for a forum non conveniens stay must identify a specific foreign court as the proposed alternative forum, and examined the applicable law connecting factors in light of the 2021 Memorandum of Understanding on Cooperation between the Supreme Court of Singapore and the Supreme People’s Court of the PRC on Information on Foreign Law.
On the case management stay, the court declined to suspend Singapore proceedings pending the PRC Divorce Proceedings. The divorce action — which D2 accepted only began in May 2025 — post-dates and was commenced after OC 107 had been substantially progressed. The court found insufficient basis to subordinate the Singapore proceedings, which concern the beneficial ownership of approximately US$600 million in assets, to a collateral foreign family-law proceeding, and dismissed the alternative ground accordingly.
Key Takeaways
- Defendants who have filed substantive defences, opposed amendment applications, and withdrawn merits-stage appeals before raising forum objections risk waiving their right to seek a forum non conveniens stay — the court squarely addressed whether such conduct constitutes waiver.
- An applicant for a forum non conveniens stay must identify a specific foreign court as the contended alternative forum; a vague assertion that “the PRC” is more appropriate is insufficient without identifying the relevant court.
- The 2021 Singapore–PRC MOU on Foreign Law Information is a relevant (though not determinative) connecting factor when assessing applicable law under the forum non conveniens analysis in cross-border PRC–Singapore disputes.
- A case management stay in favour of parallel foreign proceedings will not readily be granted where the foreign proceedings were commenced after the Singapore action was well advanced and concern a materially different subject matter.
- This case illustrates the particular complexity of high-value, multi-jurisdictional cryptocurrency disputes involving PRC family relationships, Cayman/BVI corporate structures, and Singapore-incorporated entities.
Why It Matters
This judgment provides important procedural guidance for practitioners in cross-border asset recovery and family disputes with PRC connections. It signals that defendants cannot substantively contest Singapore proceedings on the merits for over a year and then pivot to a jurisdictional exit strategy without risk of having waived forum non conveniens rights. The court’s treatment of the PRC-Singapore MOU as a connecting factor is also noteworthy, as it integrates a relatively new bilateral instrument into the conventional forum non conveniens matrix.
For counsel advising high-net-worth clients — particularly those involved in cryptocurrency businesses structured across multiple offshore jurisdictions — the case underscores the importance of raising any forum objections at the earliest opportunity, and of ensuring that any parallel foreign proceedings are clearly on foot and substantially related to the Singapore action before seeking a case management stay.
