If you or a relative has been detained in Poland, the first priority is to establish why the person is being held and which procedure applies. Immigration detention, police custody and criminal pretrial detention involve different decisions, documents and legal remedies.
Request an interpreter if needed, ask to contact a lawyer and report urgent medical needs immediately. Keep copies of documents and record the actual detention time, the authority involved and when decisions were received.
This guide explains the main distinctions, the first steps to take and the information relatives can prepare. It focuses on immigration detention while identifying the criminal custody rules that readers often confuse with it. A lawyer must assess the individual case, particularly where international protection, children or an international warrant are involved.
Which type of detention applies?
The word “detention” does not identify the legal procedure by itself. Start with the document explaining the reasons for custody.
| Situation | What to establish first |
|---|---|
| Police custody connected with a suspected offence | The suspected offence, detention time and criminal case reference |
| Immigration detention | The Border Guard case reference and any court placement order |
| Criminal pretrial detention | The court order, its reasons and the period specified |
| Detention involving an international protection application | The applicable protection procedure and the legal basis for detention |
Police custody in a criminal case is an initial measure. Criminal pretrial detention requires a court decision. Immigration detention follows a separate legal framework and does not require a criminal conviction. eli.gov.pl
Ask: “What is the legal basis for my detention, and can I receive the relevant document?”
Keep the Polish terminology on the paperwork. Translating every term simply as “arrest” can hide differences that matter when seeking assistance.
What should a detained person do immediately?
Request language assistance
In criminal custody, a person who does not sufficiently understand Polish has a right to free interpreter assistance. Official guidance also identifies rights to information about the detention, a copy of the detention record and contact with legal counsel. Portal Gov.pl
Explain which language you understand best. Being able to manage an everyday conversation does not necessarily mean you understand legal questions.
Before signing a document, request an explanation of its meaning. Point out inaccurate information and ask for your objection to be recorded. A signature can serve different purposes, including acknowledging receipt, so ask what it confirms.
Ask to contact a lawyer
Request legal assistance promptly. When explaining the situation, give the lawyer:
- Your full name and nationality.
- Your current location.
- The authority holding you.
- The actual date and time of detention.
- The case reference, if available.
- Any hearing or document deadline.
In criminal custody, the detainee may request immediate contact and a direct conversation with an advocate or legal counsel.
For immigration detention, seek someone who can assess both the detention decision and the underlying immigration proceedings.
Report medical needs clearly
Tell the officers or facility staff about medication, pregnancy, disability, injuries, serious illness or an urgent mental health concern. Request medical attention when needed.
Give specific information: the medication name, usual dose, last dose taken and what happens if treatment is interrupted. Ask relatives to locate prescriptions or medical records.
The Border Guard’s published guidance describes access to medical care and contact with legal representatives in guarded centres. Its archived guidance is useful background, but individual treatment arrangements must be checked with the facility. Aktualności Komenda Główna Straży Granicznej
Record the sequence of events
Create a short timeline:
- When freedom of movement was first restricted.
- When you reached the police or Border Guard facility.
- When interpretation and legal assistance were requested.
- When you were brought before a court.
- When each decision was received.
If an exact time is uncertain, label it as an estimate. A clear timeline is more useful than an account that mixes confirmed events with assumptions.
How long can detention last?
The answer depends on the procedure and the stage of the case.
Initial criminal custody
Under Article 248 of the Polish Code of Criminal Procedure, release is required if the detainee is not placed at the court’s disposal with an application for pretrial detention within 48 hours of detention.
After that transfer, a further 24-hour rule applies to serving the pretrial detention order or announcing it through the specified remote-hearing procedure. Release is also required when the grounds for detention cease. These rules do not make 72 hours an automatic period of permissible custody.
Initial immigration custody
Article 394 of the Act on Foreigners also provides a 48-hour court-transfer and application safeguard, followed by a 24-hour safeguard for serving the placement order. These govern initial custody, rather than the full duration of court-ordered immigration detention. eli.gov.pl
Court-ordered immigration detention
Under Article 403, an initial placement order under the Act on Foreigners specifies a period of no more than three months. Extensions require further legal assessment.
For return-related detention, EU law provides a six-month ceiling with narrowly defined extensions of up to twelve additional months. These are maximum limits, not a standard detention period. EUR-Lex
International protection follows separate rules: Article 89 of Poland’s protection legislation provides an initial placement period of up to 60 days. A case moving between legal frameworks needs an individual calculation. eli.gov.pl
Ask the lawyer to identify the current order’s expiry date and how earlier periods affect the calculation.
Can a less restrictive measure replace immigration detention?
A less restrictive measure may be available, depending on the legal grounds and circumstances.
For return procedures, EU law requires consideration of effective, less coercive measures. Detention must remain connected to its lawful purpose and last as briefly as possible.
Polish alternatives include reporting obligations, financial security, depositing a travel document and living at a designated address.
A useful proposal explains how the person would comply. Prepare truthful evidence of:
- Accommodation that is genuinely available.
- A reliable way to receive correspondence.
- A practical reporting arrangement.
- Family or other support.
- Earlier compliance with official appointments.
- Relevant health or care needs.
For example, instead of stating “I have somewhere to stay,” provide the address and supporting accommodation information. Instead of promising to attend appointments, explain how the person would travel there and receive notices.
These are preparation suggestions, not a universal statutory document list. The lawyer should select evidence that addresses the reasons given for detention.
How can detention be challenged?
Identify the particular act being challenged. Initial custody, a placement order, an extension and a return decision are different matters.
For criminal custody, official guidance states a seven-day period from detention for a court complaint examining its justification, legality and proper execution. Portal Gov.pl
For placement or extension under Article 403 of the Act on Foreigners, the appeal period is seven days from service of the order, with review by the regional court.
Keep the document and evidence of when it was received. Give both to the lawyer immediately.
Do not assume that challenging detention also challenges removal. Ask the lawyer to assess each decision, its deadline and whether a separate application concerning enforcement is necessary.
Useful questions include:
- Which decision currently authorises custody?
- Which challenge is available?
- What starts the deadline?
- Which authority should receive the filing?
- What evidence addresses the decision’s reasons?
- Have circumstances changed since the order?
Avoid waiting for a perfectly complete file before reporting a possible deadline. Send the available documents and identify what is missing.
How do health, vulnerability and age affect the case?
These circumstances require specific assessment.
Under the Act on Foreigners, danger to life or health and a psychophysical condition suggesting past violence can prevent immigration placement.
The international protection legislation contains related safeguards and a disability exclusion. Its current provisions also refer unaccompanied minors to the assessment rules in Article 397 of the Act on Foreigners. That provision permits guarded-centre placement from age 15, subject to assessment. A blanket statement that every unaccompanied minor is exempt would therefore be inaccurate.
EU return rules require particular safeguards for children, including treating their best interests as a primary consideration.
Provide accurate medical and age documents where available. Describe the practical impact of a condition: interrupted treatment, mobility problems, difficulty communicating or symptoms following violence.
For a child, explain who provides care, where the parents are and whether age is disputed. Seek assistance suited to the child’s situation promptly.
What should relatives collect?
Prepare a small, organised file rather than forwarding disconnected screenshots.
Custody information
Record the location, responsible authority, detention time and case references.
Decisions and procedural papers
Collect detention records, court orders, rights notices and hearing information. Include every page and any instruction about appeal.
Immigration documents
Gather passport pages, visas, residence cards, application confirmations and earlier decisions. Tell the lawyer which documents are current and which have expired.
Personal evidence
Locate relevant accommodation records, employment information, family documents and medical records.
This is a practical preparation checklist. It does not mean every item is required or that possession of a particular document guarantees release.
Use clear filenames such as court-order-received-2026-10-08.pdf. Preserve the original scans and send sensitive material through an agreed channel. Ask what authorisation the lawyer needs before discussing confidential case information with relatives.
Mistakes that make assistance harder
Relying on the facility’s name alone. Identify the legal basis and current order.
Using the wrong starting date. Record both the detention time and the date each decision was served.
Sending incomplete documents. Photograph all pages, including appeal instructions.
Giving inconsistent personal information. Explain errors and spelling differences rather than creating another version.
Keeping health concerns vague. State the condition, treatment and immediate problem.
Treating employment evidence as a complete answer. Give it to the lawyer for assessment alongside the immigration and detention documents.
Promising an outcome to relatives. Ask what options are available and what evidence is needed.
What should happen next?
Arrange prompt legal assessment and prepare three items: a timeline, the documents authorising custody and evidence relevant to the stated reasons.
Ask for a clear explanation of the immediate filing priorities, any missing information and the next expected procedural event. Keep one updated record of developments so that relatives and the representative work from the same facts.
Frequently Asked Questions (FAQ)
Does being detained mean I will definitely be deported?
No. Detention and a decision requiring departure are separate legal issues. Establish whether a return decision exists, what stage it has reached and which remedies apply. The detention documents alone do not give a complete picture of the immigration case. eli.gov.pl
Can my family pay money to secure my release?
Financial security is one possible immigration alternative, but offering money does not itself establish entitlement to release. Ask the lawyer whether this measure is available and appropriate, and obtain the official instructions before making a payment.
What if I cannot afford a private lawyer?
Ask about applicable legal-aid arrangements and organisations assisting detained foreigners. Eligibility and available representation depend on the procedure. Prepare your case reference, location and documents so that an organisation can assess the request efficiently.
What should I tell a lawyer if I was detained at an airport?
Give the airport, holding location, authority involved and every document received. Explain whether officers mentioned immigration status, a suspected offence or an international warrant. The location alone does not identify the procedure; warrant cases require a separate legal assessment. eli.gov.pl
