Hong Kong courts have long placed the child’s welfare at the centre of their decision-making, and that principle is increasingly shaping how the law responds to modern pathways to parenthood, including surrogacy, adoption and assisted reproduction for same-sex couples. For families whose reality does not fit the traditional model, recent cases show a quiet but important shift: judges are prepared to align legal parentage with the child’s lived family life, even where the statutory framework lags behind.
Why legal parenthood matters
For any family, “parenthood” is far more than biology. In law, however, legal parenthood is the gateway to almost every right and protection a child can rely on: a secure legal identity, immigration status, maintenance, inheritance, medical consent, and day-to-day decision-making authority. When the law does not recognise the adults who are actually raising a child, that child is left exposed. This is particularly true for LGBTQ+ families, or those who turn to surrogacy or reciprocal IVF (RIVF), where the person providing the genetic material or day-to-day care may not be the person whom the law automatically recognises as a parent.
Under Hong Kong’s default rules, the woman who carries and delivers a baby is the legal mother; if she is married, her husband is presumed to be the legal father. Those presumptions were designed for certainty but can clash with the reality of modern family‑building. A gestational carrier may have no intention of parenting the child, while the commissioning parents, often a same‑sex couple, shoulder all of the practical and emotional responsibilities.
Fortunately, the law is beginning to catch up with this distinction between biological or gestational links and “psychological parenthood” – the status of the person who is, in truth, the child’s parent in every meaningful sense. Recent decisions in the Hong Kong and UK courts demonstrate greater willingness to align parentage, and the benefits that flow from it, with the lived reality of modern families. For Hong Kong families, particularly those who have turned to assisted reproduction technologies or surrogacy, this development offers a hopeful message: the legal framework is slowly responding to contemporary family life, with the child’s welfare guiding the analysis.
Parental Orders: a critical but narrow mechanism
In surrogacy cases, the principal route to regularising parentage is a Parental Order under the Parent and Child Ordinance (Cap. 429) (PCO). A Parental Order is not a temporary care arrangement. It is a permanent, irreversible transfer of legal parentage from the surrogate (and, if applicable, her husband) to the commissioning parents. It confers full parental status, clarifies who has parental responsibility, and typically enhances the child’s prospects for secure immigration status and inheritance rights.
The PCO, however, is tightly framed. Section 12 currently limits Parental Orders to married couples – historically interpreted as opposite‑sex spouses – and imposes strict conditions:
- The child must have been carried by a woman other than the intended mother.
- At least one commissioning parent must have provided their gametes.
- The child must be living with the applicants and have a sufficient connection to Hong Kong.
- The surrogate and, if applicable, her husband must freely and unconditionally consent.
- Payments to the surrogate must be limited to “reasonable expenses,” unless the court expressly approves otherwise.
- The application must be made within six months of the child’s birth.
For opposite‑sex couples, these requirements are demanding but navigable. For same‑sex couples, the statutory exclusion from section 12 leaves them without a direct route to a Parental Order, even where their situation is functionally identical to that of a heterosexual couple.
Surrogacy and Hong Kong’s regulatory framework
Surrogacy itself is tightly regulated under the Human Reproductive Technology Ordinance (Cap. 561) (HRTO). Hong Kong prohibits commercial surrogacy and, crucially, extends that prohibition beyond its borders: Hong Kong residents may commit an offence even where the surrogacy arrangement is entered into and performed entirely overseas. In practice, many commissioning parents look abroad to jurisdictions such as California because there is more experience and clearer infrastructure for surrogacy there. Yet upon returning to Hong Kong, they can find that:
- The overseas parental order, or birth certificate naming them as parents, is not automatically recognised.
- Under Hong Kong law, the surrogate and, if married, her husband remains the legal parents.
- The commissioning parents must seek a Parental Order in Hong Kong, often within the six‑month limit and with full disclosure of payments that may appear “commercial” when assessed against Hong Kong’s standards.
The decision of FH, MH and WB, HB [2019] HKCFI 1748 illustrates both the risks and the courts’ evolving response. In that case, Hong Kong‑based commissioning parents of twins born in California had obtained a local US court order declaring them the twins’ genetic and legal parents. When they later attempted to renew the children’s dependent visas in Hong Kong, they were required to obtain a Hong Kong Parental Order and discovered, to their surprise, that they were nearly two years out of time and had made substantial payments that might have breached the HRTO’s restrictions on commercial surrogacy. The Court, treating the children’s welfare as paramount, nonetheless granted the Parental Order out of time, declared the commissioning parents to be the children’s legal parents and authorized the non-reasonable payments under section12(7) PCO. At the same time, the Judge highlighted the tension between the PCO and HRTO and called for legislative review, nothing that a rigid six-month bar serves neither the interests of the children nor the objectives of public policy.
The key takeaway in this case is that where a child has, in reality, been raised by the commissioning parents and has formed a family life with them, the court is prepared to ensure that the law reflects that reality, even if it means reading statutory time limits in a more flexible, welfare-focused way.
CS, CTW and SW: reinforcing the welfare‑first approach
A later decision, CS, CTW and SW [2024] HKCFI 2326, reinforces this approach. In that case, the children conceived in Cambodia with a Thai surrogate were brought to Hong Kong and raised as part of the commissioning couple’s family. It was only during their divorce proceedings that they learned a Parental Order was necessary.
The court again granted the Parental Order, despite delay and the parents’ reliance on ignorance of the law. However, it sounded a clear note of caution for future applicants. Commissioning parents who wish to rely on their lack of legal knowledge will be expected to demonstrate:
- Why they did not pursue surrogacy in Hong Kong and what steps they took to understand local law.
- What due diligence they carried out on the law of the foreign jurisdictions involved, beyond merely relying on assurances from a surrogacy agency.
- A clear understanding of who is treated as the legal parents in each jurisdiction and what steps have been taken to remove the surrogate’s parental rights.
In other words, while courts will not punish children for their parents’ mistakes, they expect commissioning parents, especially sophisticated professionals, to inform themselves and to act with transparency.
Adoption and same-sex families: incremental gains
Surrogacy is not the only context in which modern families confront gaps between lived reality and legal recognition. Adoption remains a crucial route to legal parenthood, but current Hong Kong legislation still confines joint adoption to opposite‑sex married couples. Same‑sex couples must typically rely on “sole applicant” adoptions.
In B v B & another [2024] HKCFI 3356, the High Court approved the adoption of a child by a married gay man acting alone. The court made clear that sexual orientation was irrelevant to the assessment of parental fitness; the overriding consideration remained the child’s best interests. While this marks a significant step forward, it also exposes a structural shortcoming: the non‑applicant spouse remains a legal stranger to the child. Families often resort to guardianship appointments or powers of attorney to bridge the gap, but these measures lack the permanence and status of full legal parenthood.
Reciprocal IVF: recognising the non‑gestational mother
For female same‑sex couples, reciprocal IVF offers a powerful way to share biological parenthood: one partner provides the egg, the other carries the pregnancy. Under existing Hong Kong rules, only the gestational mother enjoys automatic recognition; the genetic mother is, in effect, invisible in law.
A recent judgment of K (An Infant) v The Secretary for Justice [2025] HKCFI 1974, sometimes referred to as the “K Decision”, marks a significant change. In that case, a child was born via RIVF to a married lesbian couple; the court held that excluding the genetic mother from recognition was unconstitutional and failed to reflect the reality of same‑sex family life. By recognising the non‑gestational mother as a “parent at common law,” the court underlined that the law cannot assume that only heterosexual parents are capable of providing a stable, loving home. For families formed via RIVF, this decision offers a path to formal recognition without the need for adoption or surrogacy.
Trusts, succession and surrogate‑born children
For high‑net‑worth families, the question of who counts as a “child” or “issue” under historic trust deeds can be as pressing as who is named on a birth certificate. Many older Hong Kong and English law trusts were drafted on assumptions that pre‑date assisted reproductive technologies. Language such as “heirs of the body” or “en ventre sa mère” often envisages only naturally conceived, legitimate children, leaving surrogate‑born or IVF‑conceived children at risk of exclusion.
A recent English Chancery decision, Cator v Thynn [2026] EWHC 1045 (Ch), illustrates how trustees and courts can respond. In that case, a child born via a US surrogate to a British aristocratic family fell outside the literal wording of long‑standing family trusts. The trustees sought court’s approval to exercise their power of advancement to include the surrogate child in the class of beneficiaries. The court agreed, concluding that recognising the surrogate‑born child enhanced the benefit of the existing beneficiary (his father) and met a profound moral obligation to treat all children equally, regardless of the route by which they were born.
Although decided in England, the reasoning is highly relevant to Hong Kong, where trust law draws heavily on English precedent. It shows that trustees can, and arguably should, consider the inclusion of surrogate‑born or assisted‑reproduction children as consistent with their fiduciary duties, particularly where the settlor’s apparent intention was to benefit family lines rather than to penalise particular methods of conception.
Looking ahead
The overarching message from recent jurisprudence is clear: the law must align with the child’s best interests and the realities of family life, rather than outdated assumptions. At the same time, comprehensive legislative reforms remain necessary; same‑sex couples are still excluded from joint Parental Orders and joint adoption, and the HRTO’s extra‑territorial reach continues to cast a long shadow over overseas surrogacy.
The courts are increasingly prepared to interpret existing statutes in a child‑centred way, to read rigid time limits flexibly, and to ensure that children are not punished for their parents’ attempts to form a family. That said, those planning to enter into surrogacy arrangements must also be mindful of the judge’s comments in CS, CTW v SW, where the court made clear that “ignorance of the law” will not lightly excuse non‑compliance, and that commissioning parents are expected to undertake genuine due diligence on both Hong Kong and foreign legal requirements before proceeding.
Love makes a family, but in Hong Kong, meticulous legal planning protects it.
