Parental Kidnapping and the Hague Convention: When a Child Goes from the USA to Poland or Vice Versa (2026)

Taking a child without the consent of the other parent can be unlawful even in the absence of a custody ruling; this article explains when a departure constitutes kidnapping under the Hague Convention, the implications of the one-year mark, which of the eleven district courts will hear the case, how the suspension of a valid return order works, and the difference between civil unlawfulness and criminal liability.

⚠️ If your child has just been taken – six things you need to know immediately

  1. Consider the year. A petition filed within one year of the abduction is in a much better legal position. After a year, an additional ground for refusal opens up – "the child's adaptation to the new environment."
  2. A lack of custody ruling does not mean the departure was legal. The right to custody can arise from the law itself, without any court ruling.
  3. This is a civil proceeding, not a criminal one. It proceeds regardless of whether anyone has committed a crime.
  4. In Poland, the case will be heard by one of 11 district courts, and appeals go exclusively to the Court of Appeal in Warsaw, regardless of where the child lives.
  5. You need a lawyer or legal advisor – legal representation is mandatory in these matters. However, you can file the initiating petition without a representative.
  6. A valid return order does not mean the end of the case. The law provides a mechanism that suspends its execution by operation of law. This is the most commonly overlooked information in the entire topic.

This guide addresses situations where one parent takes a child abroad or does not return them after an agreed stay – from Poland to the USA or from the USA to Poland – without the consent of the other parent.

The law refers to this as unlawful abduction or retention of a child, and the mechanism for return is governed by the Hague Convention of October 25, 1980, on the Civil Aspects of International Child Abduction. Both Poland and the United States are parties to it: for the USA, the convention entered into force on July 1, 1988, after ratification; for Poland, it was November 1, 1992, after accession.

This material is for informational purposes and is not legal advice. This is the kind of case where acting independently based on an article from the internet is a bad idea – we write it so you understand the mechanism and know what to ask a lawyer, not to replace a lawyer.

When is traveling with a child unlawful

This question is resolved by Article 3 of the convention, and it is worth reading it literally, as almost every misunderstanding on this topic arises from ignorance of it:

"Abduction or retention of a child shall be considered unlawful if: a) there has been a breach of the right to custody granted to a specific person, institution, or other organization, exercised jointly or individually, under the law of the state in which the child had their habitual residence immediately before the abduction or retention, and b) at the time of abduction or retention, these rights were being effectively exercised jointly or individually or would have been so exercised but for the abduction or retention.

The right to custody referred to in point a) may arise in particular by operation of law, by a judicial or administrative decision, or by an agreement having legal effect under the laws of that state."

From this, three things arise that often surprise parents in practice.

No court ruling is needed to have a right to custody

The convention states explicitly that the right to custody can arise "by operation of law." The statement "we didn't have any ruling, so I could leave with the child" is a mistake. If both parents had parental authority and the other was actually exercising it, leaving without their consent may be unlawful despite the absence of any ruling.

The law of the country where the child previously lived decides – not the law of the country they ended up in. If the child lived in the USA, the law of the relevant state determines whether the other parent had the right to custody. The Polish court hearing the case will apply this assessment, even when ruling in Warsaw or Krakow.

The consent of the other parent matters – but it must be proven. Article 13(a) makes the basis for refusal to return the child a situation where the person exercising custody "agreed or subsequently expressed consent to the abduction or retention." The burden of proof lies with the party opposing the return.

What Polish law says about taking a child abroad

The basis is Article 97 of the Family and Guardianship Code:

"§ 1. If parental authority is held by both parents, each is obliged and entitled to exercise it.

§ 2. However, parents shall jointly decide on significant matters concerning the child; in the absence of agreement between them, the guardianship court shall decide."

The provision does not mention taking a child abroad or any other specific matter – it speaks generally about "significant matters concerning the child." In practice, a permanent departure of the child abroad is treated as such a significant matter, requiring the consent of both parents or a decision from the guardianship court. We do not provide a specific case number here, as we have not been able to verify it from the source – if this matter concerns you, ask a lawyer for guidance on current case law.

A practical conclusion for a parent planning a trip: it is advisable to have the other parent's consent in writing, with a date and indication of whether it pertains to a temporary stay or a change of residence. An oral "go ahead, no problem" is worthless in a dispute.

A year that changes everything

Article 12 of the convention is short and determines the strength of your case:

"If a child has been wrongfully abducted or retained within the meaning of Article 3, and at the time of the application being made to the judicial or administrative authority of the Contracting State where the child is located, less than one year has elapsed from the date of abduction or retention, the competent authority shall order the immediate return of the child.

The judicial or administrative authority shall also order the return of the child, even after one year (…), unless it is established that the child has already adapted to their new environment."

Note the structure. The year is not a strict deadline – after its expiration, the application is still subject to consideration. What changes is that an additional ground for refusal opens up, which does not exist before the year is up. After a year, the other party can defend themselves by claiming that the child has settled in – new school, new friends, new language.

Therefore, delay works against the parent who remains. Every month builds the argument for the other side.

When can a court refuse to return a child

The convention does not mandate unconditional return. The most commonly cited basis for refusal is Article 13(b):

"(...) the judicial or administrative authority of the requested state is not obliged to order the return of the child if the person, institution, or organization opposing the return demonstrates that: (...) b) there is a serious risk that the return of the child would expose them to physical or psychological harm or otherwise place them in an unfavorable situation."

This is the provision around which most Hague cases revolve – especially where domestic violence is involved. The burden of proof lies with the party opposing the return.

The second basis is the child's own objection:

"The judicial or administrative authority may also refuse to order the return of the child if it finds that the child opposes the return and has reached an age and degree of maturity at which it is appropriate to take their views into account."

The convention does not specify any age limit. There is no "thirteen years" or any other number – the assessment of maturity is left to the court in each specific case. If you read somewhere about a specific age as a rule, that is an addition to the text of the convention.

What the procedure looks like in Poland

The Hague proceedings in Poland were thoroughly restructured by the Act of January 26, 2018, on the performance of certain functions of the central authority in family matters. The changes came into force on August 27, 2018, and they shaped the current state.

Which court will hear the case

The Hague cases have been concentrated – they are not heard by the district court competent for the child's place of residence, as most family matters are. Article 569¹ § 1 of the Civil Procedure Code states:

"The jurisdiction of the district court seated in the locality of the appellate court includes cases for the return of a person subject to parental authority or under guardianship conducted under the Hague Convention of 1980, if the person subject to parental authority or under guardianship has their habitual residence or stay in that area."

In Poland, there are eleven appellate courts, so Hague cases in the first instance are heard by eleven district courts – in Białystok, Gdańsk, Katowice, Kraków, Lublin, Łódź, Poznań, Rzeszów, Szczecin, Warsaw, and Wrocław. For the area of the Warsaw appellate court, the law explicitly indicates the District Court in Warsaw.

Appeals go to one place, regardless of where the first instance took place. Article 518² of the Civil Procedure Code:

"§ 1. The court of second instance in cases for the return of a person subject to parental authority or under guardianship conducted under the Hague Convention of 1980 (...) is the Court of Appeal in Warsaw.

§ 2. The Court of Appeal in Warsaw shall rule in the cases specified in § 1 within six weeks from the date the first instance court submits the case files along with the appeal."

Deadlines

Return of the child after the ruling becomes finalno more than 2 weeksart. 598⁵ § 2 k.p.c.

The six-week deadlines are instructive. The convention does not provide for sanctions for exceeding them – Article 11 merely grants the right to request an explanation for the reasons for the delay. In practice, cases take longer.

A lawyer is mandatory, but not from the first document

Article 578² of the Civil Procedure Code introduces mandatory legal representation in Hague cases: "participants in the proceedings must be represented by lawyers or legal advisors". However, paragraph 2 provides exceptions that are practically important. The obligation does not apply to:

  • the application to initiate proceedings – you can submit the initiating petition yourself,
  • the proceedings for exemption from court fees,
  • the application for the appointment of a lawyer or legal advisor – that is, for a court-appointed representative.

This is important for someone without money: two applications that open the way to a free representative can be submitted independently.

A valid return order can be suspended – and this by operation of law

This is a mechanism that most studies overlook, but it can halt the case for months.

Article 388¹ § 1 of the Civil Procedure Code states that at the request of the Attorney General, the Ombudsman for Children, or the Ombudsman for Human Rights, submitted to the Court of Appeal in Warsaw within two weeks from the finalization of the ruling, "the execution of this ruling is suspended by operation of law."

The suspension ceases if no cassation complaint is filed within two months. If one is filed – it extends by operation of law until the conclusion of the cassation proceedings. Additionally, the filing of an extraordinary complaint also suspends execution by operation of law (art. 388³ k.p.c.).

Moreover, there is a subjective limitation on the cassation complaint: according to art. 519¹ § 2² k.p.c., it can be filed only by the same three authorities, within four months from the finalization. A parent cannot file a cassation complaint independently – they can only appeal to one of them.

The execution of the ruling does not happen automatically

After the ruling becomes final, the obligated party must return the child within the time specified by the court, not exceeding two weeks. If they do not do so, the court does not act ex officio. Article 598⁶ k.p.c. requires a petition: the court "at the request of the entitled party, orders the court guardian to forcibly take the person."

The process of taking also has its rules, which are worth knowing in advance:

  • the taking can occur only in the presence of the entitled party or a person authorized by them – if no one appears at the time set by the guardian, the action does not take place,
  • the obligated party is not notified of the taking date,
  • at the request of the guardian, the Police are obliged to provide assistance, and in justified cases, it is possible to search premises.

A practical conclusion for a parent living in the USA: you must be prepared to fly in a short time. Without your presence, the taking will not occur.

Where to submit the application

The Polish central authority is the Ministry of Justice. The 2018 Act adds that in performing these tasks, the minister "acts without delay."

The American Office of Children's Issues is the central authority of the USA and – as it indicates – the main point of contact in cases of children abducted both to and from the United States.

You have three ways to submit an application for the return of a child to Poland:

  1. Through the central authority of the country you are in

    That is, through the Office of Children's Issues if you live in the USA. The authority will forward the application to the Polish side.

  2. Directly to the Polish Minister of Justice

    The law explicitly allows this: the Minister of Justice accepts applications submitted by the applicant or a foreign central authority.

  3. Directly to the competent district court

    The Civil Procedure Code also provides for this situation – an application submitted without the mediation of the Polish central authority has a separate regulation.

If there are deficiencies in the application, the Ministry will call for their supplementation within four weeks. Failure to supplement means that the application will not proceed.

Little-known relief: exemption from translation costs

If you live in Poland and submit an application for the return of a child from abroad, the Minister of Justice may exempt you from translation costs of the application and attachments into the language of the requested state. Condition: you must demonstrate that you will not bear them without detriment to your own and your family's maintenance. In that case, the costs of translation are borne by the State Treasury.

When translating extensive family documentation into English, this is a significant amount. If refused, you have four weeks to submit the translation at your own expense.

Is this a crime

This is a question almost every parent in this situation asks, and the answer can be surprising.

Article 211 of the Penal Code states:

"Whoever, against the will of the person appointed to care or supervision, abducts or retains a minor under the age of 15 or a person incapable due to their mental or physical condition, is subject to imprisonment for a term of three months to five years."

Note two elements. First, the age limit: under 15 years old. Second – and this is the crux – the feature "against the will of the person appointed to care." A parent with full, unrestricted parental authority is themselves a person appointed to care, so it is difficult to argue that they are acting against the will of such a person within the meaning of this provision.

The established view is that a parent with full parental authority usually does not bear responsibility under Article 211, and the situation changes when their authority has been revoked, suspended, or limited by a court. We do not provide case numbers, as we have not been able to verify them from the source – the boundaries of this responsibility can be contentious and depend on the content of a specific ruling on parental authority.

Two planes that must not be confused

Taking a child can be unlawful under the Hague Convention and at the same time not be a crime under Article 211 of the Penal Code. This is not a contradiction – it is two different planes.

The Hague proceedings are civil. The convention itself is titled "on the Civil Aspects of International Child Abduction." It takes place before the guardianship court, and its goal is the return of the child, not to punish anyone. Reporting to the police is not a condition for initiating Hague proceedings and does not replace it.

How much does it cost and who pays

Here, one must be honest, as there is a belief that Hague proceedings are inherently free. They are not.

The convention allows a state to stipulate that it will not cover the costs of lawyer participation or court proceedings – beyond what its own legal aid system covers. Both Poland and the United States have made such a stipulation.

A practical conclusion: you will only receive a free representative if you meet the criteria of the national legal aid system. In Poland, the path looks like this:

  • Application for exemption from court fees – can be submitted independently, without a lawyer.
  • Application for the appointment of a lawyer or legal advisor ex officio – also without mandatory legal representation.
  • Application for exemption from translation costs to the Minister of Justice, described above.

We have not found verified data on typical attorney fees in Hague cases or organizations offering pro bono assistance, so we do not provide them.

The role of the consul

The 2018 Act gives the consul a specific but limited role: the Minister of Justice, the minister responsible for foreign affairs, and the relevant consul of the Republic of Poland "exchange information necessary for the performance of the tasks of the Polish central authority."

This is an exchange of information, not legal representation. The consul will not be your representative, will not conduct the case, and will not take the child. However, they can be a useful contact channel and help with documentation matters.

What to do in the first days

The following steps apply to situations where a child has been taken from the USA to Poland. The order follows the regulations described above.

  1. Establish and document where the child lived previously

    This is the foundation of the case. You must demonstrate that the child's habitual residence immediately before the departure was the United States. Gather: school and preschool documentation, medical records, rental agreements, bills, dated photos, correspondence.

  2. Document that you exercised the right to custody

    The convention requires that the right be "effectively exercised." Evidence is everyday life: picking up from school, cohabitation, contact, maintenance.

  3. Contact the central authority

    Office of Children's Issues, phone +1 202 501 4444 or +1 800 407 4747. This is the central authority of the USA and the main contact point in abduction cases both ways.

  4. Submit an application for return – and do not wait

    You can do this through the central authority of the USA, directly to the Polish Minister of Justice, or directly to the competent district court. It is crucial to do so before the one-year mark from the abduction.

  5. Find a lawyer or legal advisor in Poland

    Mandatory legal representation applies from the moment the application is submitted. If you cannot afford a representative, submit the application for the appointment of one ex officio along with the application for exemption from costs.

  6. Prepare for arrival

    Forced taking of the child can occur only in your presence or that of a person authorized by you. If no one appears, the action will not take place.

The reverse situation – a child taken from Poland to the USA – works symmetrically: the application is submitted to the Polish Minister of Justice, who forwards it to the central authority of the USA, and the case is heard by an American court. We consciously do not describe the details of the procedure on the American side here – we have not been able to verify them from the source, as the State Department's service blocks automated access. Instead of guessing, we refer you to contact the Office of Children's Issues and to a lawyer.

How not to accidentally create a problem

A large part of Hague cases begins without ill intent – from a trip "to grandma's for vacation" that extends.

  • Have written consent for the trip. With a date, specifying the return date, and clearly indicating whether it is a temporary stay or a change of residence.
  • Do not unilaterally extend the stay. Retaining the child after the agreed date is equivalent to abduction under the convention – Article 3 speaks of "abduction or retention."
  • If there is no agreement – go to the guardianship court, instead of putting the other party in a fait accompli. The Family Code explicitly states that in the absence of agreement, the court decides.
  • Do not count on the absence of a custody ruling to resolve the matter. As mentioned above – the right to custody can arise from the law itself.

Frequently Asked Questions

I went to Poland with my child before the divorce. Did I do something illegal?

It depends on whether you violated the right to custody belonging to the other parent under the law of the country where the child previously lived, and whether they were actually exercising that right. The absence of a divorce ruling does not determine anything. This is exactly the situation where you need to talk to a lawyer before a year passes.

It has been a year and a half. Is it too late?

No. After a year, the application is still subject to consideration, but the other party can defend themselves by claiming that the child has adapted to the new environment. The case becomes more difficult, but not hopeless.

The court ordered the return. When will I get my child back?

Formally, within the time set by the court, not exceeding two weeks from the finalization. In practice, you must consider two things: the final ruling may be suspended by operation of law at the request of the Attorney General, the Ombudsman for Children, or the Ombudsman for Human Rights, and the forced taking requires your petition and your presence.

Can I file a cassation complaint myself?

No. In Hague cases, cassation can only be filed by the Attorney General, the Ombudsman for Children, and the Ombudsman for Human Rights, within four months from the finalization. A parent can appeal to them with a request to consider such a step.

There is violence in the background. Will the court still order the return?

Article 13(b) allows for the refusal to return the child if there is a serious risk of exposing them to physical or psychological harm. The burden of proof lies with the party opposing the return. This is the most challenging category of cases and absolutely requires a lawyer – both for the person invoking violence and for the other party.

How long does such a case take?

The statutory deadlines are six weeks for each instance, but they are instructive – there are no sanctions for exceeding them. Additionally, there is the possibility of suspension of execution and cassation proceedings. Realistically, you should expect months, not weeks.

Related Materials

One sentence worth remembering

In Hague cases, time is on the side of the one who took the child. Every month of delay builds the argument for the child's adaptation to the new environment – therefore, the first step is not to gather strength, but to contact the central authority and a lawyer.

Status as of August 28, 2026. This material is for informational purposes and does not constitute legal advice. We have deliberately omitted case numbers from the Supreme Court and details of the procedure on the American side – we have not been able to verify them from the source, and in this category of cases, it is better to say "I don't know" than to provide unverified information. For individual matters, contact a lawyer or legal advisor specializing in international family law.
