Surrogacy

Caroline Langley has worked in international family law for more than thirty years, in Hong Kong, England & Wales, Ireland and Colorado. This page sets out how Hong Kong law treats surrogacy and international families. Her reported cases can be found here. Note that the following is general information, not legal advice.

Why This Matters

Legal recognition of same sex parenthood in Hong Kong is still developing, and the gap falls hardest on children. The law lags behind family life: same sex couples and their children face rules that do not reflect modern family structures. Where parentage is legally incomplete, children of nontraditional families are left vulnerable and unprotected. The courts are moving, and recent landmark decisions offer real hope. The guiding principle is simple. The law must follow the child's best interests and real family life, not outdated assumptions about what a family looks like.

Legal Parenthood: The Foundations

What Does the Law Mean by Legal Parenthood?

Parenthood is not decided by genetics or gestation alone. There is the genetic connection, the gametes that create the child. There is the gestational connection, carrying and giving birth. And there are social and psychological bonds: family law recognises psychological parenthood as separate from, but equal to, genetic and gestational parenthood. It matters because legal parenthood carries enforceable rights and responsibilities designed to protect the child.

The Default Rule for Carriers and Spouses

Hong Kong law starts from presumptions built around gestation and marriage. By default, the woman who carries and gives birth to the child is the legal mother. If she is married, her husband is treated as the father. Intended parents who did not carry the child do not fit that presumption, and nor do same sex couples.

Why Recognition Matters Beyond Biology

Legal parenthood gives a child a stable legal identity, not just a label. Without it, a parent and child relationship can be socially real but legally incomplete, with no enforceable remedies. For the child, that means uncertainty, less legal protection and financial disadvantage, including in inheritance.

Surrogacy Under the HRTO

What Law Regulates Surrogacy

Surrogacy is governed by the Human Reproductive Technology Ordinance (Cap. 561), the HRTO. It is a strict framework. Commercial surrogacy is prohibited entirely. Altruistic surrogacy is permitted in principle, but it is narrowly framed and restricted in practice.

What the HRTO Prohibits, and Why It Matters

The prohibitions shape what is possible before anyone goes near a court. Section 17 makes payments for surrogacy arrangements an offence. Altruistic surrogacy lacks clear, enforceable protections, and in practice it is available only to married opposite sex couples. And the woman who gives birth remains the legal mother until a Parental Order is made for the commissioning parents.

Why Many Couples Go Abroad

These limits push couples to build their families overseas, and many same sex couples go abroad to have a child linked to both partners. But the HRTO prohibitions can have extraterritorial effect, so an offence may still be treated as committed in Hong Kong. There is no clean break.

What Extraterritorial Effect Creates in Practice

Building a family abroad does not switch off Hong Kong law. The risk follows the family, wherever the pregnancy or arrangement took place, and there is no safe harbour overseas. The rule is: plan early, plan local. Take Hong Kong advice before the arrangement is made, and again after the child arrives.

Parental Orders: The Key Mechanism

What a Parental Order Is, and Why It Is Necessary

A Parental Order under section 12 of the Parent and Child Ordinance (Cap. 429) provides that a child is to be regarded in law as the child of the commissioning parents. It confers legal identity and status, defines whose child the child is, and gives the child a secure place in the family. It is irreversible, which is exactly what makes it so stable.

Why It Cannot Be Replaced by Wardship or Adoption

Wardship does not make the child the commissioning parents' child in law, and works more like custody that may end. Adoption may not recognise the genetic link in the same way, and can be slower and more complex. Without a Parental Order, there may be no legal relationship at all between the child and the biological or commissioning father. The Parental Order is the key mechanism for bringing the law into line with real family life.

The Eligibility Pathway for Parental Orders

Applications turn on a set of statutory requirements:

• Time limit: the application must be made within six months of the birth.
• Consent: the surrogate, and any relevant spouse, must consent unconditionally and with full understanding.
• Payment: only reasonable expenses, nothing commercial.
• Home and jurisdiction: requirements on where the child lives and the Court's jurisdiction.
• Age: the applicants must meet minimum age rules.
• Gametes: the gametes of one or both applicants must have been used.
• Presumptions: who the law treats as a parent. This is where same sex couples can be excluded.

Whose Gametes? The Combinations in Play

The egg and the sperm can each come from an intended parent, a donor or the surrogate. The mix decides the genetic link the law looks for.

Evidentiary Standard for DNA Testing

Section 12(1)(b) requires evidence of the genetic link between the intended parents and the baby, by a legal DNA paternity (chain of custody) test. A legal test differs from a home test in three ways: an independent third party collects the samples under documented identification; the samples are traced from collection through analysis to the report; and the report is admissible in court. The laboratory must be accredited by the AABB or to ISO/IEC 17025 under an ILAC MRA signatory body. The Court of First Instance accepts both.

Authentication of Documents for a Parental Order

Joint affidavits need only be sworn, at the High Court Registry or before a solicitor who is not acting for the parties. Clear copies of HKID cards and passports are enough, with no need to swear or notarise them. Hong Kong and the United States are both parties to the Hague Apostille Convention, so an apostille is the recognised way to certify American documents for a Hong Kong court. No statute requires it, but it is standard practice. Apostille a certified copy of the birth certificate and the judgment establishing the parent and child relationship, and the notarised affidavits of the gestational carrier and her husband, the Gestational Carrier Agreement and the agency contract.

Digital Signatures

The Gestational Carrier Agreement is the key document evidencing the arrangement, and the Court must be satisfied on both child welfare and public policy. Schedule 1 of the Electronic Transactions Ordinance excludes certain documents from electronic signature because of their profound legal effect. A GCA is not named there, but it concerns the creation of a child and the reallocation of legal parenthood, so the Court can treat it like the wills, trusts and powers of attorney that are. It makes little sense to let a document that decides who a child's legal parents are be signed by clicking a screen, before a notary who was never in the same room. In person signing guards against coercion, impersonation and trafficking. A fully digital process removes every one of those protections.

How Heterosexual and Same Sex Inclusion Differ

Married heterosexual couples are more likely to fit the statutory wording. Same sex couples are often excluded from Parental Orders under section 12, and must rely on other routes.

Alternatives When Parental Orders Are Unavailable

Those routes are second best: adoption in the country where the child was born, or private adoption in Hong Kong, outside the normal Social Welfare Department process. Often only one parent can be recognised. The result is expense, delay, litigation risk and unequal recognition within the same family.

Consent, Payment and Birth Certificates

Why Consent Decides Cases

Because a Parental Order is irreversible and confers major legal status, the Court looks hard at consent. Was the surrogate's consent free and informed? Has any legal spouse also consented unconditionally, with full understanding of what the order involves? A surrogate who refuses, perhaps because she feels badly treated, can derail the whole application.

Why Payment Rules Matter

Only reasonable expenses, or payments authorised or approved by the Court, are permitted. Anything that looks commercial can breach section 17 of the HRTO. That can make the arrangement itself unlawful, and it can block legal recognition after the birth.

Is the Overseas Birth Certificate Enough?

Not necessarily. Hong Kong can apply its own presumptions on parentage. Even if the genetic father is named on the overseas certificate, the relationship may still need to be legitimised through the correct route, such as a Parental Order. See CS and Another v SW [2024] HKCFI 2326, a case spanning Thailand, Cambodia and Hong Kong. Otherwise the commissioning father may be treated as having no enforceable rights, and face a lengthy adoption style process.

What This Creates for Families

A gap opens between the family that exists and the family the law recognises. Parent and child relationships remain legally incomplete. The child's standing for inheritance and support is weaker, and the family stays exposed in immigration and everyday legal life.

Same Sex Adoption: A Parallel Pathway

What Adoption Law Permits for Same Sex Couples

Adoption is governed by the Adoption Ordinance (Cap. 290). An adoption can be sought by a single person, or jointly by spouses. The Ordinance does not define spouse, but in practice it has been read as an opposite sex married couple. So joint adoption is usually unavailable to same sex couples, leaving sole adoption by one partner.

B v B & Another [2024] HKCFI 3356

A married gay man applied to adopt a child as a sole applicant. The Court of First Instance approved the adoption, holding that the child's best interests override concerns based on sexual orientation. The lesson: orientation alone should not disqualify a parent, yet the procedure still limits the legal status of the other partner. Read the judgment.

What Happens to the Non Applicant Spouse

After a sole adoption, the other partner and the child can be legal strangers. There is no way to secure maintenance against the non applicant partner, and no stable legal parentage to rely on. Guardianship and wardship are often temporary or revocable, and may end when the child turns eighteen. They do not cure the lack of durable legal recognition.

Reciprocal IVF and the K Decision

What Is Reciprocal IVF?

In a female same sex couple, both partners can contribute biologically. One provides the egg, the genetic link. The other carries the pregnancy, the gestational link. But the default rule intrudes: Hong Kong law may still treat only the woman who gave birth as the legal mother.

The Legal Gap for the Genetic Mother

Sharing biology does not guarantee shared legal status. The genetic mother does not automatically become a full legal parent, because the law favours gestation, and the adoption and Parental Order routes are limited for same sex couples for the reasons above.

K (An Infant) v Secretary for Justice [2025] HKCFI 1974

A child born through reciprocal IVF to a lesbian couple challenged the different treatment of his family. Coleman J found the differential treatment unconstitutional and recognised the non gestational mother as a parent at common law. The lesson: a changing world requires legal systems to be astute to families formed outside married or heterosexual relationships. Read the judgment.

What Remains and What Must Change

Comprehensive reform of Hong Kong's parentage and child protection laws is overdue. Until it comes, same sex couples must find their way through a complex and unequal system, often through costly litigation. The clearest gaps are joint adoption and parentage recognition in surrogacy for same sex couples. The child's best interests should guide the law, not assumptions about family form.

Heterosexual parents have no monopoly on good parenting. It is difficult to justify placing extra hurdles on same sex parents to prove their parenting serves the child's best interests, when heterosexual parents face no equivalent test.
