J, Ss also known as Ssj Formerly Known As Ssn v. Sja

On 28 July 2026, District Judge I Wong handed down a ruling in J v SJA, FCMC 12024/2023, [2026] HKFC 133, holding that section 9 of the Matrimonial Causes Ordinance, Cap 179, on its plain wording does not support the wife's contention that a potentially polygamous marriage celebrated in Pakistan becomes monogamous for jurisdictional purposes simply because the husband has always been domiciled in Hong Kong. Ms Bonnie YK Cheng (now Cheng SC), instructed on legal aid, appeared for the successful respondent husband.

The petitioner wife and respondent husband are both of Pakistani origin, though the husband has been domiciled in Hong Kong throughout. They married in Pakistan on 1 January 2008 under the Muslim Family Ordinance 1961, which permits a man to take a second wife with the permission of an Arbitration Council. The wife moved to Hong Kong in September 2008, and both parties are now Hong Kong domiciled. The wife petitioned in October 2023 for divorce on the ground of two years' separation. The court raised the jurisdictional point of its own motion once it noticed the polygamous character of the marriage, and about 13 other similar cases have been held over pending this ruling.

The wife advanced two grounds: (i) the husband's Hong Kong domicile stripped him of the capacity to enter a polygamous union anywhere, so Pakistani law is not engaged and the marriage is de facto monogamous; and (ii) the character of the marriage should be assessed at the date of the petition, relying on the English line of authority in Cheni v Cheni [1965] P 85, Ali v Ali [1966] 2 WLR 620, and the local decision in Yeung Yeu-Kong v Yeung Fung Lai Mui [1971] HKLR 15.

The court held that: (1) section 2 provides an exhaustive definition of 'monogamous marriage' and on its plain wording a marriage outside Hong Kong must be 'recognized' as monogamous by the law in force at the time and place of celebration (§43); (2) the English 'monogamisation' doctrine, premised on a change of domicile, has no foothold in Hong Kong, where the legislature instead used the validation and registration mechanism in the 1971 Marriage Reform Ordinance to convert Chinese customary unions (§§81-84); (3) Yeung Yeu-Kong turned on statutory conversion by registration under section 38(2) of the Marriage Ordinance, not on domicile (§76); and (4) under Pakistani law the marriage was at least potentially polygamous, so the wife has not yet established the jurisdictional threshold (§101).

Costs were reserved, with a counsel certificate, and case management directions on whether to commission an expert opinion on Pakistani family law will be issued separately.

Why it matters

Practitioners with divorce petitions involving marriages celebrated in jurisdictions that permit polygamy should now expect a section 9 challenge at the threshold and prepare to address the law of the place of celebration, not the parties' domicile, on the question of jurisdiction.
