Yiu Ka Kui v. Tay Gak Yong and Tay Fengyi, Administrators of the Estate of Ching Mun Fong (also known as Ching Fook Fook) and Another

HCAP 23/2025 · [2026] HKCFI 4059 · Court of First Instance · 2026-07-20 · published 23 July 2026

Background

The plaintiff, Yiu Ka Kui, is a maternal nephew of Ching Mun Fong, who died in Singapore on 11 November 2023 leaving an estate worth over SG$1.9 billion (§3, §67). The deceased had resided year-round in Singapore since 2006 and was survived only by her daughter Collin and Collin's two children, the Tay Children (§6, §19). Within four days of the death, the Tay Children applied for and obtained a grant of letters of administration in Singapore on an intestacy basis, then had it re-sealed in Hong Kong on 5 March 2025 (§4, §8).

The plaintiff commenced this probate action in June 2025 seeking revocation of the Hong Kong Grant under s 33(1) of the Probate and Administration Ordinance (Cap 10), alleging that the Tay Children failed to make a thorough search for a will and that the deceased had in fact told him in around 2015 she had made a will in Singapore (§5, §21). The plaintiff also proposed the appointment of an administrator pendente lite to conduct further searches (§23, §35). The defendants responded with a striking-out summons on the grounds that the SOC discloses no reasonable cause of action, is frivolous or vexatious, and is an abuse of process (§34).

Key findings

1. The plaintiff lacks locus standi to invoke s 33 of the Ordinance because he has no present interest in the estate (§§53-54, §57). The SOC merely pleads it is "reasonable to infer" he would be named as beneficiary or executor, which is contingent and speculative rather than an asserted interest (§§57-58). 2. A likelihood or expectation of an interest is insufficient to ground locus, and no authority was cited to support such a proposition (§59). 3. Issuing proceedings without locus standi is prima facie an abuse of process; there are no rival claims in this action for the court to adjudicate in its in rem capacity (§60). 4. The claim for revocation based on non-intestacy is fatally flawed because no will has been pleaded, located or particularised, and the deceased could have changed her testamentary intention after 2015 (§§61-63). 5. The claimed relief pronouncing for a will "upon discovery of the same" presumes the will's existence and amounts to hoping something turns up, which is an abuse of process (§64). 6. On the duty to make searches, the court applied common sense: the alleged will was executed in Singapore where the deceased resided, the HSBC Safe Deposit Box has been inspected and yielded no will, and the plaintiff himself controls access to the two Hong Kong premises (§§69-72, §84). 7. While the duty to make all necessary inquiries is well-established (Re Estate of Yeh Lien Teh; Chung Chiu Hing v Personal Representative of Law Sam; Re Estate of Lam Choi Bo Ming; Re Estate of Kwok Mei Lung at §§47-51), the plaintiff has not shown a prima facie breach in the Hong Kong context given the Singapore-focused nature of the alleged will. 8. The Singapore Grant operates in rem and until it is revoked, the Hong Kong Grant obtained by resealing under s 49 should not be revoked; this creates a forum and sequencing problem for any Hong Kong challenge (§§85-87). 9. The doctrine of abuse of process under Ko Hon Yue v Chiu Pik Yuk (§§89-90) is engaged: the plaintiff previously filed a caveat, failed to enter an appearance to warning despite being represented, and made a second unsuccessful attempt to file another caveat (§§91-92). His lack of interest would have rendered the earlier caveat frivolous (§93). 10. The court accepted the plaintiff acts out of genuine duty rather than greed (§96), but this did not cure the threshold defect in locus standi (§97).

Why it matters

This decision is a useful reminder that locus standi under s 33 of the Probate and Administration Ordinance requires a present, pleaded interest in the estate, not merely a hope or inference that one might benefit under a will yet to be found (§§54, §59). Practitioners advising potential challengers to a resealed grant should plead a concrete interest and be prepared to particularise the will's existence rather than rely on inference. The decision also signals Hong Kong courts' reluctance to entertain revocation actions where the primary grant is in a foreign jurisdiction and operates in rem, absent prior revocation of that foreign grant (§§85-87). Finally, the case reinforces that prior failed attempts to challenge a grant through the caveat process may be used as evidence of abuse under Ko Hon Yue (§§89-94), though the court stopped short of holding that caveat proceedings are the only permissible avenue (§95).
