Couples with children face the closest scrutiny, because the court has an active duty under section 18 of Cap. 192. That duty covers children under 16 and older minors still in education or training, so a teenager at boarding school in the UK belongs in the Form 2D statement. Thin arrangements can prompt a social investigation report from the Social Welfare Department, which adds months to the timetable. In genuine urgency, section 18(1)(c) allows the decree to be made absolute first, against an undertaking to return the arrangements to court within a fixed time.
Cross-boundary couples married on the Mainland, or holding property in Guangdong, should draft with enforcement in mind. The Mainland Judgments in Matrimonial and Family Cases (Reciprocal Recognition and Enforcement) Ordinance (Cap. 639) provides for a Hong Kong decree absolute and related orders to be recognised in the Mainland, and for Mainland orders to be recognised here. That mechanism rewards unambiguous orders. A maintenance term naming the currency, payment date and bank channel travels far better than a promise to "support the children".
Expatriate couples married abroad should check how their home country treats a Hong Kong decree before relying on it to remarry or to claim pension rights there. The Hong Kong court dissolves a marriage celebrated overseas once section 3 jurisdiction is established, with no local registration of the marriage needed. Once both spouses have left, domicile or substantial connection may still found jurisdiction, but proving either is slower and less certain, so filing before departure keeps the case on the residence limb.
Property and business assets are where agreed divorces most often unravel after the decree. A flat held as joint tenants passes by survivorship, so a buy-out should be completed by assignment, or the joint tenancy severed, rather than left as an intention; if the couple sells to a third party instead, the sale runs through an agreement for sale and purchase of Hong Kong property under Cap. 219. Where one spouse holds shares in a family company, any transfer must respect the shareholders agreement governed by the Companies Ordinance (Cap. 622), including pre-emption rights. Hong Kong has no pension-sharing order, so MPF accrued benefits cannot be split at source and are usually offset against other assets. A private agreement on any of these points does not bind the court until it is embodied in a consent order.
