Arrested in Turkey as a Foreigner: Custody, Pre-Trial Detention and Release

How long can a foreigner be held in police custody in Turkey?

In Turkey, police custody lasts 24 hours from the moment of arrest; the travel time needed to take the person to the nearest judge is added to this, but it cannot exceed 12 hours. These rules are in the Code of Criminal Procedure No. 5271, and they apply in the same way to Turkish citizens and to foreigners.

For crimes committed collectively, the public prosecutor can extend police custody by 3 days, by no more than 1 day each time. In this way, custody can reach 4 days at most. The extension order is in writing and is served on the person in custody immediately. There is no general rule that "custody lasts 48 hours for serious crimes"; the 48-hour limit applies only to custody ordered by the police in certain cases of a crime caught in the act.

This article explains police custody, pre-trial detention and judicial control in a criminal investigation. Being stopped at passport control at the airport, an Interpol Red Notice, extradition proceedings and a criminal investigation conducted while you are abroad are subject to separate rules.

How do you challenge police custody before the criminal judge of peace?

You can apply to the criminal judge of peace (sulh ceza hâkimi) against police custody, and the judge decides the application before 24 hours have passed. The application is made against the arrest, the custody decision or the prosecutor's extension order; its aim is the person's immediate release.

The right to apply does not belong only to the person in custody. The defence lawyer (müdafi), the legal representative, the spouse and first- or second-degree blood relatives can also apply. Mother, father, children, grandchildren, siblings, grandmother and grandfather are within this group.

The judge reviews the application on the documents. If the judge finds the custody justified, he or she rejects the application or orders the person to be brought immediately to the public prosecutor's office together with the investigation documents. This application is different from an objection to a pre-trial detention decision; the time limit and the authority for an objection to detention follow separate rules.

A person released because the custody period ended or on a judge's decision cannot easily be arrested again for the same reason. For this, new and sufficient evidence and a decision of the public prosecutor are needed.

What decisions can the criminal judgeship of peace make about a detained foreigner?

On the prosecutor's request, and after questioning the foreigner, the criminal judgeship of peace (sulh ceza hâkimliği) makes one of 3 decisions: release, judicial control or pre-trial detention. Criminal courts of peace were abolished in 2014; today, criminal judgeships of peace make these decisions during the investigation stage.

Pre-trial detention requires strong suspicion of a crime, a ground for detention and a proportionate measure, all together. The judge must also explain, with concrete facts, why judicial control would not be enough.

The table below shows the condition and the result of the 3 decisions that can be made after questioning (Law No. 5271; checked in November 2026).

Turkey has no separate bail system; a security deposit (güvence) is only one of the judicial control obligations.

For this reason, the answer in Turkish law to the question "Can I pay bail and get out?" is judicial control. The judge sets the amount of the security deposit by taking into account the person's financial situation.

For which crimes can a foreigner not be held in pre-trial detention in Turkey?

Pre-trial detention cannot be ordered for crimes that carry only a judicial fine or for crimes whose maximum prison sentence does not exceed 2 years (Law No. 5271, Art. 100/4). Intentional crimes against bodily integrity are outside this prohibition. For example, for a charge of intentional injury, pre-trial detention is possible even if the maximum sentence is low.

A prohibition on pre-trial detention does not mean a prohibition on judicial control. The Law clearly accepts that judicial control can be applied even where pre-trial detention is prohibited. For this reason, a foreigner taken into custody on a minor charge may face a ban on leaving the country even if he or she is not detained.

Fixed answers to the question "How many months can you be held in pre-trial detention in Turkey?" that do not look at the charge are also misleading. The maximum periods vary depending on whether the case falls within the jurisdiction of the high criminal court (ağır ceza mahkemesi) and on the type of crime.

Does a foreigner in police custody in Turkey have the right to a lawyer and to remain silent?

Yes. A foreigner in police custody, like a Turkish citizen, has the right to the help of a lawyer and the right not to make a statement about the charge. The lawyer's meeting with the suspect and presence during the statement cannot be prevented. The right not to make a statement is one of the rights that must be reminded to the suspect before taking a statement.

If a suspect is not in a position to choose a lawyer, the bar association appoints a defence lawyer on request. For crimes with a minimum prison sentence of more than 5 years, for children and for persons with a disability that prevents them from defending themselves, a defence lawyer is appointed without a request. When the prosecutor requests pre-trial detention, the suspect also has the help of a defence lawyer he or she has chosen or that the bar association has appointed.

These rights have a practical result. A statement taken by the police without a defence lawyer present cannot be the basis of a judgment unless it is confirmed before a judge or court. In criminal cases of foreigners, the defence therefore starts in the first hours of custody. Who took the statement, in which language and in whose presence can be decisive in later stages.

Are an interpreter and consular notification mandatory for a foreigner who does not speak Turkish?

Yes. A suspect who does not know Turkish well enough to express himself or herself is given an interpreter also during the investigation stage. The judge or the public prosecutor appoints the interpreter, and the cost is not charged to the suspect; the State Treasury pays it.

In its decision of 9 February 2026 (E. 2025/10257, K. 2026/1269), the 10th Criminal Chamber of the Court of Cassation (Yargıtay 10. Ceza Dairesi) reversed the judgment. The Chamber held that taking the defence of a foreign defendant without asking whether he knew Turkish and whether he wanted an interpreter was a restriction of the right of defence. The statement of a person who said "I know Turkish" to the police can also be disputed later if it turns out that his or her Turkish was not sufficient.

A relative of the person taken into custody, or a person he or she chooses, is informed without delay on the order of the public prosecutor. For foreigners, there is also the following rule: "If the person arrested or taken into custody is a foreigner, his or her situation shall be notified to the consulate of the State of which he or she is a national, unless he or she objects in writing." (translated from the official Turkish text) (Law No. 5271, Art. 95/2)

This rule is broader than the Vienna Convention on Consular Relations; the Convention makes notification depend on the person's request. A foreigner who does not want contact with the authorities of his or her country, for example a person with an international protection application, can object to this notification in writing.

Does being a foreigner alone count as a risk of absconding in Turkey?

No. Under the law, suspicion of absconding must be based on concrete facts, and the Constitutional Court requires this suspicion to be established by looking at the person's whole situation. According to the Court, "the nature of a crime or the severity of the penalty that may be imposed for it cannot always be accepted as a situation showing that there is a danger of absconding" (translated from the official Turkish text). The personal factors considered together in the assessment are:

• whether the person has a fixed place of residence,
• his or her profession and assets,
• ties arising from family or work,
• the way he or she was arrested and his or her conduct during the process,
• special circumstances that make it easier to go to or stay in another country.

Suspicion of absconding is established by looking at the person's whole situation; foreign nationality is only one of these factors.

Pre-trial detention of a suspect who also holds Kazakh citizenship: what did the Constitutional Court say?

Can a foreigner under judicial control leave Turkey?

No. If the judicial control decision includes an obligation not to leave the country, the foreigner cannot leave Turkey unless this obligation is lifted. Judicial control consists of one or more obligations chosen by the judge instead of pre-trial detention (Law No. 5271, Art. 109/3). The obligations that directly affect a foreigner's daily life are:

• not leaving the country,
• reporting at regular intervals to a set place (commonly called "signing"),
• not leaving his or her home or a certain residential area,
• paying the security deposit set by the judge.

The continuation of judicial control is reviewed at least once every 4 months. Its duration is also limited: in cases outside the jurisdiction of the high criminal court, it is at most 2 years and can be extended by 1 year where necessary. In high criminal court cases, the period is 3 years and can be extended with stated reasons. A deliberate breach of an obligation can lead to pre-trial detention.

For a foreigner who has no fixed address in Turkey and stays in a hotel, address and means of living matter in 2 ways: in the discussion of the suspicion of absconding and in applying the reporting obligation. Requests and objections to lift a ban on leaving the country follow separate rules.

How long do you have to object to pre-trial detention in Turkey, and how is detention reviewed?

The time limit to object to a pre-trial detention decision is 2 weeks from the day the decision became known; this period was increased from 7 days to 2 weeks by Law No. 7499 in 2024. An objection to detention and judicial control decisions of the criminal judgeship of peace is reviewed by the judge of the criminal court of first instance in the same judicial district (Law No. 5271, Art. 268/3-b).

Even if the time limit for objection passes, the route to release is not closed. The suspect can ask for release at any stage of the investigation. During the investigation stage, the criminal judge of peace also reviews the continuation of detention at intervals of 30 days at most, after hearing the suspect or the defence lawyer. During the prosecution stage, the court makes this assessment at every hearing.

Decisions on continued detention must also give reasons. In its decision of 17 February 2026 (B. No: 2024/38780), the Constitutional Court found a pre-trial detention unlawful. The evidence it was based on was already in the hands of the investigating authorities, and the decision had no concrete reasoning about the suspicion of absconding.

What is the maximum length of pre-trial detention in Turkey?

During the investigation stage, pre-trial detention cannot exceed 6 months in cases outside the jurisdiction of the high criminal court, and 1 year in high criminal court cases. For terrorist crimes, certain crimes against the security of the State and crimes committed collectively, this period is 1 year 6 months and can be extended by 6 more months.

The upper limits for the whole case are longer. In cases outside the jurisdiction of the high criminal court, pre-trial detention is at most 1 year and can be extended by 6 months where necessary. In high criminal court cases, the period is 2 years; extensions cannot exceed 3 years in total, or 5 years for terrorist crimes and certain crimes against the security of the State.

For children who were under 15 when they committed the act, these periods apply at half; for children under 18, they apply at three quarters. The periods are a ceiling, not a right; detention must be justified again at each review.

Can the consulate and family visit a foreigner held in pre-trial detention in Turkey?

Yes. The consulate or diplomatic mission of the State of which the detained foreigner is a national can ask for a visit, and this request is met without delay. For nationals of States that have no consulate, for refugees and for stateless persons, the meeting takes place with the mission or organisation that protects their interests.

The spouse and blood relatives and relatives by marriage up to the third degree can make 1 visit a week, provided that the relationship is documented. These rules were written for convicted persons and apply to detainees to the extent that they are compatible with pre-trial detention. A meeting with a lawyer is separate from a visit; except for the exceptions in the law for organisation and terrorist crimes, it cannot be listened to or recorded.

Can a foreigner convicted in Turkey serve the sentence in his or her own country?

Yes, but only after the conviction becomes final and if the conditions in the law are met together (Law on International Judicial Cooperation in Criminal Matters (6706 sayılı Cezai Konularda Uluslararası Adli İş Birliği Kanunu), Art. 32). The main conditions for the transfer of sentenced persons are:

• being a national of the State of transfer or having strong social ties with that State,
• the consent of the sentenced person or his or her legal representative,
• the act also being a crime under the law of that State,
• as a rule, at least 6 months of prison sentence remaining to be served,
• no investigation or prosecution for another crime in Turkey.

If there is also a judicial fine along with the prison sentence, this fine must be paid for the transfer; the unpaid part is converted into a prison sentence and taken into account. The Minister of Justice decides on the transfer after the consent of the foreign State.

A foreigner in pre-trial detention cannot be transferred to his or her country in this way without a final conviction.

Can a criminal case lead to deportation from Turkey?

A criminal case does not automatically result in deportation, but it can affect the foreigner's immigration law situation in 2 ways. The situation of a foreigner sentenced to prison is reported to the Ministry of Interior after the sentence is served or after conditional release (Turkish Penal Code No. 5237, Art. 59). For a foreigner considered a threat to public order or security, a deportation order can be issued even without waiting for a conviction.

The deportation order (sınır dışı etme kararı) and administrative detention (idari gözetim) are not criminal procedure measures but administrative acts of the governorship (valilik). The table below compares 4 measures that are often confused (Laws No. 5271 and 6458; checked in November 2026).

Release in the criminal file does not automatically end a separately issued deportation order or administrative detention.

The remedies against these decisions are covered separately in the topics of the lawsuit against a deportation order and administrative detention in a removal centre.

Can a foreigner who was wrongly detained in Turkey claim compensation?

Yes. A person arrested or detained contrary to the law can claim pecuniary and non-pecuniary damages from the State. A person who was lawfully detained and then received a decision of non-prosecution (kovuşturmaya yer olmadığı kararı) or an acquittal also has this right. The law does not link this right to citizenship; a foreigner can also claim compensation.

The time limit for applying is 3 months from service of the notice that the decision has become final, and in any case 1 year from finality. After the 2024 amendment by Law No. 7499, the competent authority depends on the reason for compensation:

• in cases such as a decision of non-prosecution or an acquittal, or detention longer than the sentence, the Compensation Commission (Tazminat Komisyonu) within the Ministry of Justice,
• in other cases, such as unlawful arrest or detention, the high criminal court.

An application to the Compensation Commission can also be made through the Chief Public Prosecutor's Office or electronically. Objections against the Commission's decisions can be made to the Ankara Regional Administrative Court (Ankara Bölge İdare Mahkemesi) within 15 days from service.

Which documents matter in the file of a foreigner detained in Turkey?

In the file of a foreigner in custody, what decides the case is not the number of documents but the document that answers the suspicion of absconding and the charge. In a dispute about pre-trial detention, documents showing ties to Turkey come first; in problems with interpreters and statements, the official records come first.

• About identity and legal stay: passport, residence permit card, foreigner identification number, entry and exit records.
• About ties to Turkey: lease agreement or title deed, employment contract and work permit, marriage and children's records.
• About the criminal file: custody and extension records, statement and questioning records, the pre-trial detention or judicial control decision, the date the decision became known.
• About health and special circumstances: medical reports, documents on pregnancy or a recent birth, documents showing a duty of care.

Not every file needs all of these documents. The same lease agreement may support judicial control in one file and be irrelevant to the charge in another. Which document is submitted is decided after the file is examined.

Conclusion: concrete facts in the file, not nationality, decide a foreigner's release

A foreigner taken into police custody in Turkey is subject to the same time limits and the same safeguards as a Turkish citizen. As a rule, he or she is brought before a judge within 24 hours, has the right to a lawyer and an interpreter, and his or her consulate is notified unless he or she objects in writing. Whether these rights were used in the first hours affects the whole later discussion.

The main question before the criminal judge of peace is the suspicion of absconding. Foreign nationality is taken into account in this question, but it is not enough by itself; address, work, family and conduct during the process in Turkey are weighed together. When 2 foreigners are taken into custody on the same charge, one may be released under judicial control and the other detained because of differences in these facts.

The route does not close after a pre-trial detention decision either: there is the 2-week objection period, the 30-day reviews and the request for release that can be made at any time. The criminal file runs separately from the immigration law consequences, and those consequences must be assessed separately.
