Family Law in Poland for Expats: Divorce, Child Custody and International Parental Disputes (2026)

Family law disputes are among the most difficult legal matters any person faces. When they occur in a foreign country — or involve parents of different nationalities — the complexity multiplies. Polish family law has specific rules on divorce, asset division, child custody and international parental abduction that differ substantially from common-law systems. This guide outlines the key principles for expats and international families.

Divorce in Poland

Polish law recognises only judicial divorce — there is no administrative divorce and no equivalent of an uncontested "quickie divorce" as in some jurisdictions. Both parties appear before the family court. If both parties agree on all terms (custody, alimony, division of the marital home), the court can grant a divorce in a single hearing. If there is any dispute, the proceedings can take 12–36 months.

Polish law permits divorce on the ground of complete and permanent breakdown of the marriage only — fault (adultery, desertion) is not a legal ground but may be addressed in the proceedings if one party requests that the court rule on fault. A fault ruling affects alimony entitlements.

Division of Marital Assets

In the absence of a prenuptial agreement, Polish law creates a statutory joint marital estate (wspólność majątkowa) covering assets acquired during the marriage. Inherited assets and gifts received by one spouse remain separate property. On divorce, the joint estate is divided equally unless the court orders an unequal split (which requires showing that one party contributed significantly more).

Prenuptial agreements (intercyzy majątkowe) separating property during marriage are valid and increasingly used by international couples. They must be executed before a Polish notary.

Child Custody in Poland

Polish courts operate on the principle of the child's best interests. Joint custody is the default presumption after divorce; sole custody is granted only where joint custody is impractical. The court will appoint a court-supervised family diagnostic centre (OZSS) to assess the child's situation and the parents' fitness before making a custody order.

For international families, the question of which country's courts have jurisdiction is governed by EU Regulation 2019/1111 (Brussels IIb) for EU residents, or by the Hague Convention on Parental Responsibility for other cases. Jurisdiction generally lies in the country of the child's habitual residence.

International Parental Abduction

Poland is a signatory to the 1980 Hague Convention on International Child Abduction. If a child is removed to Poland without the other parent's consent, the left-behind parent can apply for immediate return through the Polish Central Authority (the Ministry of Justice). Polish courts are required to decide return applications within 6 weeks. English-speaking specialists — particularly Wardyński & Partners and Lawyersinpoland.com — handle these urgent cross-border matters.

Frequently Asked Questions

Is a foreign divorce recognised in Poland?

Yes, if the divorce was granted in an EU member state, it is automatically recognised under EU Regulation 1259/2010 (Rome III). Non-EU divorces require a recognition procedure before a Polish court.

Can I take my child out of Poland without the other parent's consent?

Only if you have a court order granting you that right, or written notarised consent from the other parent. Removing a child without consent is a criminal offence in Poland and may engage the Hague Convention.

How is alimony calculated in Poland?

Alimony (alimenty) for children is calculated based on the child's justified needs and each parent's earning capacity. There is no fixed formula; courts consider all circumstances. Average court-ordered alimony ranges from PLN 700 to PLN 2,500 per child per month.
