No parenthood without a genetic link

[Federal Court of Justice, order of 13 May 2026 – Case No. XII ZB 220/25]

1. What was it about?

On 13 May 2026, the Federal Court of Justice (BGH) is due to rule on the case of a German woman who is a single mother and who without using one’s own gametes had a child carried to term via surrogacy in Mexico. Following the birth, a Mexican court ruled that the German intended mother, rather than the surrogate mother, was the child’s legal mother – even though she is not genetically related to the child. On this basis, the intended mother was also entered on the birth certificate in Germany. The question now was: must the registry office accept the foreign court’s decision on parenthood – or should the surrogate mother instead be entered as the mother on the German birth certificate? In the view of the Family Court, the surrogate mother was the correct mother; the Higher Regional Court took a different view and ruled in favour of the intended mother. The Federal Court of Justice reinstated the Family Court’s decision. The decisive factor was that the intended mother was, as Single mum not genetically related to the child.

2. When are foreign decisions on parenthood not recognised?

The Federal Court of Justice states: A foreign court ruling on parentage following surrogacy is, as a rule, recognised in Germany not recognised if none The prospective parent is genetically related to the child. The rationale behind this is a fundamental principle of German law („ordre public“): essential German values and safeguards must not be undermined. According to the Federal Court of Justice (BGH), this includes the principle that, as a rule, legal parenthood for persons without a genetic link can only be established through a Adoption procedure can be justified – that is, subject to a specific assessment of the child’s best interests and the parents’ suitability by the courts, the youth welfare office, etc.

3. The role of genetics

In its ruling, the Federal Court of Justice (BGH) emphasises that the decisive factor in establishing parenthood is the Genetic ancestry from:

• Is at least one If the prospective parent is genetically related to the child, a foreign decision on parentage may, in principle, be recognised (as has already been stated in previous decisions of the Federal Court of Justice).
• Is there any genetic link between the child and the intended parents; in the view of the Federal Court of Justice (BGH), such recognition regularly contravenes fundamental principles of German law.

The Federal Court of Justice (BGH) thus draws a clear line: Without a genetic link – no direct recognition of parenthood despite a foreign court ruling.

4. Adoption as a planned route to parenthood

In cases where there is no genetic relationship, the Federal Court of Justice generally refers the intended parents to the Adoption:

• Adoption means that a court – in consultation with, amongst others, the youth welfare office – assesses whether it is in the child’s best interests for a person to become a legal parent and whether that parent is suitable for the role.
• In the view of the Federal Court of Justice, the German legislature deliberately provided for this option in cases where there is no genetic link between the child and the prospective parents.

In the case in question, the Federal Court of Justice ruled that the surrogate mother to be entered as the mother in the birth register. Prospective parents could then acquire legal parenthood through adoption proceedings.

5. What does this mean for the individuals and couples affected?

If you are planning to undergo surrogacy abroad or have already done so, and none Whether you are genetically related to the child has significant implications from a German perspective:

• A foreign court ruling that designates you as a parent is, as a rule, recognised in Germany in accordance with the position of the Federal Court of Justice (BGH) not (more) recognised. Instead, the Surrogate mother be registered as the mother in the German birth register.
• Prospective parents would have to adopt. This usually takes no less than two years. Although the Federal Court of Justice emphasises that the route via adoption effectively and promptly must be left open so that the solution is compatible with the protection of the child and the family. At the same time, however, experience shows that adoption procedures can be time-consuming and fraught with uncertainty.
• Parents who are already registered could lose their parental status at the request of the registry office – with far-reaching consequences in areas such as family law, inheritance law, youth welfare law, nationality law, tax law and health insurance law.
• You may face significant difficulties when leaving the country, as you may not be able to obtain a German passport for your child.
• As a result of the tightening of the law, the recognition of paternity could be subject to approval by the immigration authorities, as a discrepancy in residence status is likely to arise. The period of residence in the child’s country of birth may be significantly extended.
• As the surrogate mother is registered as the child’s mother, the child cannot derive their nationality from you.
• Without parental status, you will not be granted custody; this also affects day-to-day matters relating to acting on the child’s behalf. There is a risk of guardianship being imposed, or even of the child being taken into care.

6. Different legal systems clash

Many countries where surrogacy is permitted regulate parenthood regardless of genetic ancestry to the intended parents – for example, on the basis of a court order or judgement. In such cases, foreign courts routinely scrutinise the entire surrogacy process „from top to bottom“, including the surrogate mother’s voluntary participation and, in particular, the child’s best interests. The Federal Court of Justice (BGH), by contrast, focuses solely on the genetic link and does not wish to allow such foreign decisions to circumvent the German system of protection (in particular adoption law). This leads to tensions:

• In other countries, intended parents are often regarded as the legal parents from the moment of birth.
• In Germany, this form of parenthood not be recognised if there is no genetic link to the child.

The Federal Court of Justice bases its restrictive stance on the Child protection and on concerns about misuse:

• The Federal Court of Justice (BGH) regards surrogacy without any genetic contribution from the intended parents as particularly problematic and sees a risk that children will be „ordered“ and treated like commodities.
• The adoption process is designed to ensure that there is no exploitation of financial hardship or any improper placement practices, and that the child’s best interests are the primary consideration.

7. A dynamic legal landscape – why it is important to seek advice at an early stage

The ruling forms part of a series of judgements on surrogacy, but marks a turning point in cases with no genetic link A significant tightening of the rules: recognition of foreign parenting decisions will become the exception, whilst adoption will become the norm.

At the same time, there is a debate amongst experts and politicians as to whether,

• whether and how the German regulations on surrogacy should be amended,
• whether there should be specific rules governing the recognition of foreign judgments,
• and how adoption procedures can be speeded up and made more practical.

The legal position is therefore on the move – particularly in light of international developments.

If you are planning to use a surrogate mother abroad, or if a child has already been born via surrogacy abroad, you should seek advice as early as possible:

• Which scenarios are realistically recognised under current Federal Court of Justice (BGH) case law?
• What steps need to be taken in Germany regarding birth certificates, nationality and residence?
• What adoption options are available in your specific case, and how can delays and risks be minimised?
