International child abduction to Poland is usually not a case of a stranger kidnapping a child. In most situations, it is a dispute between parents. One parent takes the child to Poland without the other parent’s consent, refuses to return the child after a holiday, or keeps the child in Poland despite an agreement that the stay was only temporary.

For the left-behind parent, this can be an extremely stressful and confusing situation. The child may suddenly be enrolled in a Polish school, the other parent may stop answering messages, or contact may become limited. However, in legal terms, the most important issue is not which parent is “better”. The key question is whether the child was wrongfully removed from, or retained outside, the country of his or her habitual residence.

In many cases, the main legal instrument is the 1980 Hague Convention on the Civil Aspects of International Child Abduction. Poland is a Contracting Party to this Convention, and the Convention entered into force for Poland on 1 November 1992. The purpose of the Convention is to secure the prompt return of children wrongfully removed to or retained in another Contracting State.

Before starting return proceedings, it is important to verify whether the Hague Convention is in force between Poland and the other country involved in the case. This is particularly important where the other country joined the Convention by accession. The Hague Convention also applies only where the child was habitually resident in a Contracting State immediately before the breach of custody or access rights. It ceases to apply when the child reaches the age of 16.

Wrongful removal and wrongful retention

A child may be wrongfully removed to Poland if one parent brings the child to Poland without the consent of the other parent who has custody rights under the law of the child’s previous country of habitual residence. However, many cases involve wrongful retention rather than removal. This may happen when the other parent initially agrees to a short visit to Poland, for example for holidays or family reasons, but the travelling parent later refuses to bring the child back.

Wrongful retention may be particularly difficult because the first stage of the journey was lawful. The dispute starts when the agreed return date passes and the child is kept in Poland against the will of the other parent. Evidence is therefore crucial: messages confirming the holiday arrangement, return tickets, school records abroad, medical records, proof of residence and any correspondence showing that the stay in Poland was meant to be temporary.

Habitual residence of the child

The concept of habitual residence is central in Hague Convention cases. It does not necessarily mean nationality, citizenship, passport, registration address or the country where the extended family lives. A child may be a Polish citizen and still have habitual residence in England, Germany, France, Spain, the Netherlands, Belgium, Ireland, Norway or another country.

Polish courts will usually look at the factual centre of the child’s life before the removal or retention. Important factors may include school or nursery attendance, language, medical care, family routine, social environment and the stability of the child’s day-to-day life. In the case of very young children, the court may also examine the parents’ shared intentions and the practical organisation of family life.

What is the aim of Hague Convention proceedings?

Hague Convention proceedings are not ordinary custody proceedings. The Polish court should not decide which parent should ultimately have primary care of the child. The aim is more limited: to determine whether the child should be returned to the country of habitual residence so that the courts of that country can decide long-term parental responsibility issues.

This distinction is very important. A parent applying for the return of the child does not have to prove that he or she is the better parent. The focus is on whether the removal or retention breached custody rights and whether those rights were actually exercised or would have been exercised but for the abduction.

Child abduction within the European Union

If the child was taken to Poland from another EU Member State, the 1980 Hague Convention may be supplemented by Council Regulation (EU) 2019/1111, commonly known as Brussels IIb. This Regulation concerns jurisdiction, recognition and enforcement of decisions in matrimonial matters, parental responsibility matters and international child abduction. It complements and reinforces the 1980 Hague Convention in parental child abduction cases between EU Member States.

The Brussels IIb Regulation applies between EU Member States, with the exception of Denmark, and generally to proceedings instituted on or after 1 August 2022. Proceedings instituted before that date may still fall under the previous Brussels IIa Regulation.

EU rules are designed to prevent a parent from creating a more favourable forum by abducting a child. In principle, the court in the country where the child had habitual residence before the abduction remains responsible for parental responsibility issues until the abduction case has been settled.

How quickly should a parent act?

Speed is essential. The longer the child remains in Poland, the more likely it is that the abducting parent will argue that the child has settled into the new environment. Under the Hague Convention, the one-year period from the wrongful removal or retention can be important. If proceedings are started quickly, the return mechanism is usually stronger. If more than one year has passed, the court may examine whether the child has become settled in the new environment.

The procedure is designed to be handled urgently. Under the Hague Convention, judicial and administrative authorities are required to act expeditiously. If no decision is reached within six weeks, the applicant or the Central Authority may request a statement of the reasons for the delay. In EU cases covered by Brussels IIb, the return mechanism is reinforced by time limits intended to ensure a decision within six weeks at each relevant court level.

Can a Polish court refuse to return the child?

Yes, but the exceptions are limited. The court may refuse return in specific circumstances, for example where there was no wrongful removal or retention, where the left-behind parent was not actually exercising custody rights, where the left-behind parent consented to or later acquiesced in the removal or retention, where there is a grave risk that return would expose the child to physical or psychological harm, or where an older and mature child objects to return.

These exceptions should not be treated as a general custody assessment. A parent opposing return must normally prove more than the fact that the child is comfortable in Poland or has relatives there. On the other hand, where there are genuine safety concerns, domestic violence allegations or serious psychological risks, these matters must be presented carefully and supported by evidence.

In EU cases, where grave risk is alleged, the court should also consider whether adequate protective arrangements can be made in the State of return. This may be important where the return of the child is possible only if specific safeguards are put in place.

Practical steps for the left-behind parent

A parent whose child has been taken to Poland should immediately gather documents proving the child’s habitual residence, the parent’s custody rights and the temporary nature of the trip. Useful evidence may include court orders, custody agreements, birth certificates, school documents, medical documents, residence confirmations, travel documents, text messages, emails and evidence of day-to-day care.

It is also important to avoid procedural mistakes. Starting ordinary custody proceedings in Poland without considering the Hague Convention strategy may cause complications. The legal objective should be clear from the beginning: return of the child to the country of habitual residence, contact arrangements, protective measures, or a broader parental responsibility dispute.

Hague Convention courts in Poland

In Poland, Hague return applications are handled by designated regional courts at first instance. Appeals in these cases are heard by the Court of Appeal in Warsaw. This means that not every local family court in Poland will be competent to hear an international child return case.

Even if the left-behind parent already has a lawyer abroad, Polish legal representation may be necessary because the proceedings take place in Poland and follow Polish procedural rules. A Polish lawyer can assist with the Hague Convention application, evidence, translations, contact with the Central Authority, urgent motions and representation before the Polish court.

Child abduction to Poland requires fast, precise and well-documented action. The sooner the legal position is assessed, the better the chances of avoiding unnecessary delay and preventing the unlawful situation from becoming more difficult to reverse.

Frequently asked questions

Does the Hague Convention apply to every child?

It applies to children habitually resident in a Contracting State immediately before the removal, and it ceases when the child turns 16. Always check that the Convention is in force between Poland and the other country.

How quickly should I act?

As fast as possible. The one-year period matters and the procedure is urgent (a six-week guideline). Acting early strengthens the return application.

Does the Polish court decide custody?

No. Hague proceedings concern only the return to the country of habitual residence; custody is then decided by the court of that country.
