Which country's law applies to my divorce in the EU?

Under the EU's Rome III Regulation, couples can choose which law applies to their divorce. If they do not agree, the court will determine it based on factors such as habitual residence, nationality, or the location of the court hearing the case.

How is child maintenance decided across EU borders?

Child maintenance is governed by the EU Maintenance Regulation (4/2009) and the 2007 Hague Protocol. Generally, the law of the child's habitual residence applies, and maintenance decisions from one EU country are directly enforceable in another.

Can I file for divorce in one EU country if my spouse lives in another?

Yes. Under the Brussels II ter Regulation (2019/1111), you can file for divorce in a country where you or your spouse have habitual residence, nationality, or are domiciled (for Ireland). The court that is first validly seised generally has jurisdiction.

Divorce and child maintenance basics in the EU

Plain-language guide · reviewed for general accuracy · European Union

Divorce and child maintenance can be complex when more than one EU country is involved. The EU has established a set of regulations to help determine which country's courts can hear a case, which law applies, and how maintenance orders can be enforced across borders. Here is what you need to know.

1. Which country handles the divorce?

The Brussels II ter Regulation (2019/1111) sets out the rules for jurisdiction — that is, which EU country's court may hear a divorce case. You can generally file in a country where you and your spouse are both habitually resident, where you were last habitually resident (if one of you still lives there), where either of you is habitually resident (in certain circumstances), or where either of you is a national. The court that receives a valid application first usually has priority — this is known as the "first seised" rule. This means it can be important to act promptly if you prefer a particular country's legal system.

2. Which law applies?

Under the EU's Rome III Regulation (1259/2010), a couple can agree in writing to choose the law of a country with which they have a close connection — for example, the country of their habitual residence or nationality — to govern their divorce. This is known as "enhanced cooperation" and currently applies in 17 EU member states. If no choice is made, the court determines the applicable law using a hierarchy of connecting factors: habitual residence of the spouses, their last habitual residence (if one still lives there), or their common nationality.

3. Child maintenance — how it works across borders

Child maintenance (child support) in cross-border EU cases is governed by the EU Maintenance Regulation (4/2009) and the 2007 Hague Protocol. The general rule is that maintenance is determined by the law of the country where the child is habitually resident. However, in certain circumstances, the law of the court hearing the case — the lex fori — may apply. Maintenance decisions issued in one EU member state are directly enforceable in another without any special declaration of enforceability (the exequatur has been abolished). This means a parent can seek enforcement of a maintenance order in another EU country without going through a lengthy recognition procedure.

Tip: if you have children and you and your spouse live in different EU countries, think carefully about where you file for divorce. The country where the case is handled can affect both the division of assets and the child maintenance calculation.

4. Parental responsibility and child custody

The Brussels II ter Regulation also covers parental responsibility — including custody and access rights. The general rule is that the courts of the child's habitual residence have jurisdiction. If a child has been wrongfully removed or retained across an EU border, the 1980 Hague Convention on Child Abduction applies alongside the Brussels II ter procedures, which aim to secure a return decision within six weeks.

5. Recognition and enforcement across the EU

Divorce decrees and decisions on parental responsibility and maintenance from one EU country are generally recognised in all other EU member states without any special proceedings. You will typically only need to present a certified copy of the judgment and, where applicable, a standard certificate issued by the court. This makes cross-border family law matters significantly more straightforward within the EU than outside it.

Common questions

Where should I file for divorce if we live in different EU countries?: You can file in a country where either of you is habitually resident or a national. The court that receives the valid application first generally has priority, so timing can matter.
How is child maintenance calculated across EU borders?: The law of the child's habitual residence usually determines the amount. Maintenance orders from one EU country are directly enforceable in another without additional proceedings.
Can my spouse take our child to another EU country without my consent?: Generally, removing a child across an EU border without the consent of all holders of parental responsibility is unlawful and can trigger proceedings under the Hague Convention and Brussels II ter for the child's return.
