In 1989, Denmark became the first country in the world to legalise same-sex partnerships. More than 35 years later, there is still no unified European standard for same-sex parents. Each country decides for itself — and the answers vary enormously.
For a same-sex couple with a child, this has real consequences: crossing a border can change their legal status. A child with two legal parents in one country may, in another, find themselves with one — or in outright legal limbo.
This article isn’t legal advice. It’s a map of how the law currently works across key European countries, across four dimensions: recognition at birth, joint adoption, donor conception, and surrogacy.
Before the table, it’s worth understanding what each category actually means in practice.
When a parent has a biological connection to the child, getting their name on the birth certificate is straightforward. But what about the second parent? In some countries, a same-sex partner is automatically recognised as a parent at birth if the couple is married. In others, a separate legal application is required. In others still, the only route is formal adoption.
This refers to a couple’s right to adopt a child together — from a domestic care system or internationally — as a couple, rather than as a single applicant. In some countries, same-sex couples can adopt jointly. In others, one partner adopts as a single person, and the other has no parental status at all.
Two things matter here: whether donor conception is legally available to same-sex couples at all, and how parenthood is established. For female couples using donor sperm, the key question is whether the co-mother is automatically recognised. For male couples using donor eggs, it’s about how fatherhood is legally established.
The most complex and inconsistent category. Most EU countries either prohibit surrogacy outright or leave it entirely unregulated. Where it is permitted, it’s typically altruistic only — no commercial arrangements. And who counts as the legal mother — the surrogate or the intended mother — is answered differently in each country.
Behind these tables are real situations. Here are three scenarios that show what the legal differences actually look like on the ground.
Spain legalised same-sex marriage in 2005 — among the first countries in the world to do so. Since then, legal parenthood for same-sex couples has been brought as close as possible to what’s available to heterosexual couples. Both mothers are registered on the birth certificate automatically when donor sperm is used at a licensed clinic — no extra procedure required. Joint adoption is available. Donor conception programmes are open to same-sex couples.
The one significant gap is surrogacy. Commercial surrogacy is prohibited. Couples who have used surrogacy abroad — in countries like Ukraine or Greece — frequently run into difficulties registering their children in Spain; courts have consistently declined to recognise such arrangements.
Germany legalised same-sex marriage in 2017, but the legal system hasn’t fully caught up. A second parent in a same-sex couple — whether a co-mother or co-father — does not receive automatic parental status at birth. The only path is step-parent adoption: an application, a review by the youth welfare office, and a court decision.
The process can take anywhere from several months to a year and a half. During that time, the second parent has no right to make medical decisions for the child, is not their legal heir, and cannot take the child abroad unilaterally. A reform intended to fix this has been under discussion since 2023, but as of early 2025, it has not been passed.
The UK permits altruistic surrogacy and is one of the few European countries where male same-sex couples can become parents through a surrogate. But ‘permitted’ doesn’t mean ‘simple’.
Under British law, the surrogate is the legal mother of the child until a court says otherwise. The intended parents must apply for a Parental Order — a specific judicial ruling transferring parenthood. Without it, they have no parental status, even if one of them is the biological father.
The process typically takes several months and requires legal representation. The surrogate must give her consent after the birth — consent given in advance has no legal force. If she changes her mind, the situation becomes extremely complicated.
The European Court of Human Rights has repeatedly held that states must ensure legal recognition of parent-child relationships established abroad, in the best interests of the child. But how that principle is implemented is left to each country.
Check the rules in your country of residence. Laws change. What was true three years ago may no longer apply — in either direction.
Being married gives you more rights in almost every European jurisdiction. Civil partnership and marriage are legally distinct in many countries.
Clarify the process for the second parent. Even where everything is supposedly ‘automatic’, make sure that’s actually true for your specific method of conception.
If you’re using surrogacy abroad, consult a lawyer in your home country about how parenthood will be recognised when you return — before starting the process, not after.
Apostille and certified translation of the birth certificate is standard procedure if the child is born in another country. But document requirements vary.
In 2023, the Court of Justice of the European Union ruled that EU member states are obliged to recognise parenthood established in another member state for the purposes of freedom of movement. This is a significant step — but not a universal fix. It applies to specific circumstances and does not override national laws on civil registration.
The legal route to recognised parenthood for same-sex couples varies significantly across European countries and beyond. Here is a practical overview of the most common destinations.
One of Europe's most same-sex-family-friendly jurisdictions. Same-sex marriage has been legal since 2005. Both parents in a same-sex couple can be registered at birth. Adoption by same-sex couples is permitted. Spain also recognises parenthood established in countries with legal surrogacy, though this requires a court process.
Same-sex marriage since 2017, but the parenthood framework has gaps. The non-biological parent in a same-sex couple must formally adopt the child — even if the couple is married. The adoption process typically takes 1–2 years. Germany does not recognise surrogacy, which means parenthood established through surrogacy abroad is not automatically transferred.
Comprehensive legal framework. Same-sex couples can jointly register as parents at birth if both are Dutch citizens. The Netherlands recognises foreign birth certificates, including those from countries with legal surrogacy, under certain conditions.
Civil partnerships since 2004, same-sex marriage since 2014. A non-biological parent who is the civil partner or spouse of the birth mother is automatically recognised as a legal parent. For surrogacy, a parental order is required — a court-supervised process that takes several months.
Same-sex marriage since 2013. France is one of the more restrictive EU countries for non-biological parents: the second parent must adopt the child even within a marriage. France does not recognise surrogacy — foreign surrogacy arrangements are systematically challenged in French courts, though post-2019 case law has gradually allowed recognition under specific conditions.
Same-sex marriage since 2003. Non-biological parents must adopt, unless the couple used co-maternity procedures (both women involved in reproduction). Complex rules for cross-border cases.
Same-sex marriage since 2010. Legal co-parenthood for same-sex couples since 2016. Altruistic surrogacy was legalised in 2016 but implementation has been inconsistent.
In April 2023, the Court of Justice of the European Union ruled in the Pancharevo case (C-2/21) that EU member states must recognise the free movement of a child even if they do not recognise the family structure used to create that family. In practice: if a child holds a birth certificate issued by one EU member state naming two parents of the same sex, all other EU member states must allow that child to move freely and must issue them a passport or identity document — even if the issuing member state does not recognise same-sex parenthood itself.
This is significant but limited. The ruling concerns the child's freedom of movement — not the recognition of the parental relationship as such. A country can still refuse to register the second parent on its own documents while being obliged to allow the child to reside and travel.
Before committing to a particular route to parenthood, there are several questions that need country-specific answers.
Does your country of residence recognise co-parenthood between two parents of the same sex at birth, or is a post-birth legal process required? In some countries — Germany, France, Belgium — even within a marriage, the non-biological parent must formally adopt.
If you are using a known donor, what parental rights does the donor have in your country? In many jurisdictions, a known sperm donor who donates without a formal written agreement retains legal paternity rights. This can be removed contractually in some countries but not all.
If you are using a surrogate in another country, what process do you need to complete in your home country after the birth? The answer ranges from straightforward registration to a full adoption process taking 1–2 years.
Are there residency or citizenship requirements? Some countries — Greece in particular for surrogacy — require one or both intended parents to be residents or nationals.
Both partners should understand which parent will be the biological parent (if applicable) and how this affects legal status in your home country.
If using a known donor, have a formal written agreement prepared by a family lawyer before any conception attempt. This agreement should address parental rights, financial obligations, and the nature of the donor's involvement in the child's life.
If using a surrogate abroad, ensure you understand both the legal requirements in the country of birth and the recognition process in your home country. These are two separate legal tracks, and both matter.
Keep documentation of every step of your family-building process. Courts in multiple countries have required proof of genetic parentage, medical procedures performed, and agreements signed — sometimes years after the child was born.
