International family law disputes can be legally complex. This is certainly the case in a border region such as Limburg, where living, working and family life often span several countries. Consider, for example, parents of different nationalities or parents living in different countries; a minor child moving abroad with one of their parents; married expats living in the Netherlands who wish to divorce; or a foreign court judgement that needs to be amended.

When a family law dispute has international aspects, it is not always clear which court has jurisdiction or which national law should be applied. For example, a Dutch court may have jurisdiction to rule on a dispute, whilst at the same time having to apply foreign law. Nor is there always the freedom to choose in which country proceedings are initiated.

The applicable rules can vary considerably from country to country and thus have significant legal and financial consequences. It is therefore important to carefully determine in advance which court has jurisdiction, which law applies and what options the parties involved have.

In a recent judgment by the Limburg District Court dated 15 October 2026 (ECLI:NL:RBLIM:2026:11503) , the central question was whether a Dutch court was permitted to reassess child maintenance orders made by a German court in accordance with Dutch standards.

What were the facts of this case?

A minor child was living with his father in Germany. A German court ruled that the child would live with his mother in the Netherlands from July 2024, established a care arrangement between the father and the child, and set the child maintenance at €577.93.

In 2025, the father initiated proceedings in the Netherlands to reduce the child maintenance set by the German court to €61.00 with effect from December 2024.

In support of his application, the father argued, amongst other things, that the German judgment had failed to meet the legal requirements from the outset, because the German court did not have jurisdiction to rule on this case, the German court had not taken sufficient account of the care arrangements in place between the father and the child; and that the mother had entered into a registered partnership in 2024, as a result of which her partner had also become liable for the child’s maintenance. In the Netherlands, this latter development constitutes a change in circumstances that justifies a review of the amount of child maintenance.

How will the court rule in this case?

Which court has jurisdiction and which law should be applied?

As the child now resides in the Netherlands, the father must, in accordance with the rules of private international law, apply to the Dutch court for a variation. For the same reason, Dutch law must be applied in this case.

As the father had argued that the German court did not have jurisdiction to make a decision in 2024, the Dutch court must first rule on this point. The court found that the German court did have jurisdiction to rule on the determination of child maintenance in 2024 and that, in doing so, it was also required to apply German law. The father was resident in Germany and, under the applicable private international law, the mother was entitled to submit her application to the German court. The Dutch court saw no grounds – as the father had claimed – for concluding that the mother had abused her procedural rights by initiating proceedings in Germany.

This means that in 2024, the German court had jurisdiction to make a decision on child maintenance based on the German criteria in force at that time.

The Dutch court must then determine whether there has been a change in circumstances that is relevant under the legal system on which the original decision was based. This is therefore German law. Only if this is the case will a fresh assessment be made as to whether the amount of child maintenance should be adjusted in accordance with Dutch law.

Under German law, the changed circumstances cited by the father (a change in the care arrangement and the presence of a stepfather) do not give rise to an adjustment. Under German law, these facts are not relevant to the determination of the amount of child maintenance. As there is no relevant change under German law, the Dutch court does not need to recalculate the child maintenance.

It was in the father’s interest for the German judgment of 2024 to be amended in accordance with Dutch law. The fact that the mother has entered into a registered partnership and that her partner has also become liable for maintenance of the minor child is a fact that is not relevant under German law. Nor is the care arrangement established between the person liable for maintenance and the child of any significance in Germany. In the Netherlands, however, this does constitute grounds for a variation, as there are now no longer two persons (father and mother) liable for maintenance, but three (father, mother and stepfather).

Recommendations

Have international jurisdiction assessed in advance

Initiating proceedings in the wrong country can result in unnecessary time and costs. In family law proceedings with international aspects, it is important to establish in advance:

• which court has jurisdiction?;
• welk recht moet en/of kan worden toegepast?;
• welke financiële gevolgen hebben de antwoorden van de bovengenoemde vragen voor uw zaak?
  .

Kijk niet alleen naar het Nederlandse recht

Wanneer een buitenlandse rechter eerder een beslissing in een alimentatiezaak heeft genomen, is het niet vanzelfsprekend dat Nederlandse recht wordt toegepast door de Nederlandse rechter. Laat daarom eerst onderzoeken welk recht destijds van toepassing was op de uitspraak en welke maatstaven hierbij zijn gebruikt. Een verandering die naar Nederlands recht belangrijk is, hoeft dat in een ander land niet te zijn.

Verwacht niet dat gunstigere Nederlandse regels automatisch worden toegepast

Deze uitspraak laat zien dat een Nederlandse rechter terughoudend is bij het openbreken van buitenlandse alimentatiebeslissingen. De rechter maakt duidelijk dat een partij niet zonder meer kan overstappen van de Duitse naar de Nederlandse berekeningsmethode, alleen omdat de uitkomst gunstiger zou zijn.

Conclusion

Deze uitspraak laat zien dat bij internationale alimentatiezaken niet alleen wordt gekeken naar de huidige woonplaats van het kind, maar ook naar de juridische uitgangspunten waarop een eerdere buitenlandse beslissing is gebaseerd.

Het is dan ook belangrijk om bij dit soort zaken van tevoren goed te laten uitzoeken welke rechter bevoegd is, welk recht toegepast moet worden en welke feiten en omstandigheden in een situatie relevant zijn. Daarom is het aan te raden om bij internationale familierechtprocedures juridisch advies van een in het familierecht gespecialiseerde advocaat in te winnen.
