Judicial control (adli kontrol) in Turkey is the set of obligations a judge orders instead of pre-trial detention when the grounds for detention exist but liberty under conditions is enough: a ban on leaving the country, reporting to a police station on fixed days, a deposit of security, house arrest with or without an electronic tag, a ban on approaching certain people or places, treatment for addiction, or the surrender of a driving licence or weapons. It is ordered by the criminal judgeship of peace (Sulh Ceza Hakimliği) during the investigation on the prosecutor's request and by the trial court afterwards, it must be reviewed at least every four months, it is subject to maximum durations since 2021, and a wilful breach allows the court to order detention whatever the sentence the offence carries.
- Judicial control requires the same grounds as detention, strong suspicion and a risk of flight or of tampering with evidence, and a detention order must say why judicial control would not do.
- The measures are listed in the Code of Criminal Procedure; the judge picks one or several, and house arrest counts towards the sentence at half rate.
- The need for each measure is reviewed at least every four months; judicial control may last two years plus one in ordinary cases and three plus three in high criminal court cases.
- The suspect may ask for a measure to be lifted at any time, decided within five days, and may object to a decision within two weeks.
- A wilful breach allows immediate detention and the loss of the security; a foreign suspect under a travel ban needs a residence permit to stay lawfully while the case runs.
What judicial control is and when a judge orders it
Turkish criminal procedure treats detention before judgment as the exception. A judge may order detention only where there is strong suspicion that the person committed the offence and either a concrete risk of flight or a concrete risk that the person will destroy, hide or alter evidence or pressure witnesses, victims or others; for a list of serious offences in the Code of Criminal Procedure (Ceza Muhakemesi Kanunu), including homicide, drug trafficking, sexual offences, organised crime and terrorism, the law allows the grounds to be presumed from the charge, subject to the facts of the case. Detention is not permitted at all for offences punishable only by a fine or by imprisonment with an upper limit of two years or less. Judicial control is the alternative the same provisions offer: where the grounds for detention exist, the judge may place the person under judicial control instead, and the law requires every detention order to state in writing why judicial control would be insufficient, which is the sentence the defence attacks first in any objection.
Until 2012 judicial control was available only for offences carrying a short maximum sentence; an amendment that year removed the ceiling, so that judicial control may now be ordered for any offence, and it may also be ordered where detention itself is prohibited, as a lighter measure in a minor case. The decision is taken during the investigation by the criminal judgeship of peace on the prosecutor's request, usually at the end of police custody when the prosecutor brings the suspect before the judge asking for detention or judicial control, and during the prosecution by the court hearing the case, at the first hearing or at any later one. The judge hears the suspect and defence counsel before deciding, and the choice between release without conditions, judicial control and detention is the judge's, not the prosecutor's; in our files the hearing at the end of custody is where the outcome is usually settled, because a judge who has once found detention necessary is harder to move than a judge deciding for the first time.
What moves the judge is evidence of ties and of the absence of risk: a registered address and a lease or title deed, employment or a business in Turkey, a spouse and children here, a residence permit in good standing, bank accounts, a passport that can be deposited, and a record of having attended every summons so far. For a foreign suspect, nationality alone is not a ground for detention, but the practical question the judge asks is whether a ban on leaving the country can be enforced and whether the person will be found at the address given, and the defence answers it with documents rather than assurances. Our practice page on the criminal lawyer in Turkey covers the investigation and trial as a whole; this article covers the measures that keep a suspect at liberty while they run.
The measures the court can impose
The Code lists the obligations a judge may impose, alone or in combination: not to leave the country; to report regularly to the places the judge designates, which in practice is a police station on fixed days and at fixed hours, the reporting obligation known as the signature obligation (imza yükümlülüğü); to comply with the summonses of the authorities or persons the judge names and with control measures concerning work or education; not to drive vehicles, or certain vehicles, and where required to deposit the driving licence against a receipt; to undergo examination or treatment, including admission to hospital, to overcome dependence on drugs, stimulants or alcohol; to deposit a sum of security set by the judge on the prosecutor's request, in one payment or instalments, having regard to the suspect's means; not to possess or carry weapons and to surrender those held; to give security, in kind or personal, for the victim's rights in an amount the judge sets; to give an undertaking to meet family obligations and to pay maintenance ordered by a court; not to leave the home; not to leave a defined residential area; and not to go to defined places. A ban on approaching the victim or witnesses is imposed under the last of these, and in domestic violence cases through the separate protection order regime.
The judge matches the measure to the risk the detention request relies on. A risk of flight is met by the ban on leaving the country, the reporting obligation and security, in that order of frequency; a risk of pressure on witnesses by the ban on approaching them and on going to certain places; a risk connected with addiction by treatment; an offence committed with a vehicle by the driving ban. The judge is free to combine measures and often does, and the common order for a foreign suspect in a non-violent case is the travel ban with reporting once or twice a week, with security added where the person has means and few ties. A measure that bears no relation to the alleged risk is open to objection as disproportionate.
Time under judicial control is not deducted from a later sentence, with two exceptions: time spent in inpatient treatment under the treatment measure, and time under house arrest, which counts at half rate, every two days under house arrest being credited as one day of the sentence. A person released because the maximum period of detention has expired may be placed under judicial control for the rest of the case, and a person whose detention is replaced by judicial control during the case keeps the credit for the days spent in custody. Practice may vary by authority and year.
Security, house arrest and electronic monitoring
Security (güvence) is not bail in the common-law sense, where money buys release; it is one of the listed measures, ordered on the prosecutor's request, and the judge fixes the amount by reference to the suspect's financial situation and the purpose the security serves, with payment in one sum or in instalments. The law assigns the security two functions: to secure the suspect's attendance at every stage of the proceedings and at the execution of any sentence, and to secure, in order, the costs the victim incurred and the damage caused by the offence together with any maintenance debt, the public costs of the proceedings, and any fine. The judge, court or prosecutor may order the part reserved for the victim's rights to be paid to the victim. The deposit is made to the court's cashier or the designated account, and a bank guarantee is accepted in practice where the decision allows it; in our files the amount for a foreign suspect is set with an eye to the suspect's income abroad, because a sum that is trivial to the person secures nothing.
The security is returned in stages. If the person has met every attendance obligation, the part securing attendance is returned, and the part reserved for the victim and for costs is returned on a decision not to prosecute or on acquittal, without waiting for the judgment to become final. If the person fails to meet the obligations without a valid excuse, the security is forfeited to the Treasury; on conviction the second part is applied to the costs, damages and fine and any excess is returned.
House arrest (konutu terk etmeme) confines the person to the home, with the judge's decision stating the exceptions, usually court dates, lawyer's appointments and medical appointments, and a defined residential area or a list of prohibited places may be ordered instead. Both are implemented through the probation directorate (Denetimli Serbestlik Müdürlüğü), which may fit an electronic tag on the ankle or wrist under the probation regulation: the unit reports the person's position to the electronic monitoring centre, the directorate sets the permitted area, and leaving it, blocking the signal or removing the unit raises an alarm that is reported to the judge or court. The Court of Cassation has treated damaging the unit as the offence of damaging property in addition to the breach, and in practice a reported violation is followed by a detention request within days. The person bears the practical burden of keeping the unit charged and of asking the directorate in advance for any absence the decision does not cover.
The travel ban and the reporting obligation in daily life
The ban on leaving the country is the most common measure for foreign suspects. It is notified to the police and recorded in the border system, so that the person is stopped at any land, sea or air exit, and the judge may in addition order the passport to be deposited; the passport itself remains the property of the issuing state, and a foreign suspect whose passport expires during the case renews it through the consulate and notifies the court of the new number. The ban does not restrict movement within Turkey, but a person who also has a reporting obligation must be at the designated police station on the designated days, so a move to another city needs an application to transfer the reporting place. Travel abroad while the ban is in force is possible only with the judge's or court's permission on an application showing the reason, the dates and the return, and in our practice such permission is granted rarely and for documented reasons such as the death or serious illness of a close relative, often against an increase in security; a person who leaves without permission is treated as having fled.
The reporting obligation is simple to state and the commonest source of breaches: the decision names the station, the days and the hours, the person attends, shows identification and signs the register, and the station reports every missed signature. A missed day for a documented reason, hospital admission, a court date elsewhere, a flight cancelled on the way back from another city, is excused on an application filed at once with the documents; a missed day explained afterwards, when the prosecutor has already asked for detention, is weighed against the whole record. In our files the client is given the decision in translation on the day it is made, with the days and hours marked, and the first signature is made together with counsel.
Work and study are compatible with most measures. The judge may make compliance with work or education arrangements a condition in itself, a reporting day that falls on a working day is moved on request, and a residential-area restriction is drawn to include the workplace; where the measure is a ban on going to certain places and the workplace is one of them, as in an offence alleged against an employer or a colleague, the defence asks for the ban to be limited to contact with the complainant. Practice may vary by authority and year.
Review, time limits, modification and objection
Judicial control is not fixed for the life of the case. Since the 2021 amendments the judge or court must examine at least every four months whether each obligation is still needed, on the prosecutor's request during the investigation and of its own motion during the trial, and the same amendments set maximum durations: in cases outside the jurisdiction of the high criminal court, two years, extendable by one year for compelling reasons stated in the decision; in high criminal court cases, three years, extendable by up to three years, or by up to four years for terrorism offences and offences against the constitutional order; and half of those periods for children. The Constitutional Court held in a decision given in December 2025 and published in April 2026 that time under judicial control after the first-instance judgment, during appeal and cassation, counts towards the maximum, a point on which the Court of Cassation's practice had gone the other way; a person whose case is on appeal with the travel ban still in force should have the period recomputed on that basis.
The suspect or accused may at any time ask the judge or court to lift or change a measure, and the law requires a decision within five days after the prosecutor's opinion is taken; the prosecutor may ask for a measure to be added, removed or changed, and the judge may grant a temporary exemption, which is the route for a single permitted trip or a change of reporting station. The application is a petition with documents, and the ones that succeed in our experience are those filed after a clean period of compliance, with a specific and modest request: reporting once a week instead of twice, a transfer of the reporting place, the return of the driving licence, the replacement of house arrest by a travel ban.
Every judicial control decision, including a refusal to lift or change a measure, is subject to objection. The objection is filed within two weeks of learning of the decision, a period that was seven days until the amendment that took effect in June 2024 and is still quoted as seven days in older texts, with the judge or court that gave the decision, which either corrects it or passes the objection to the reviewing authority, the next-numbered criminal judgeship of peace during the investigation and the higher court during the trial; the objection does not by itself suspend the measure. A person whose objection fails may bring an individual application to the Constitutional Court for a violation of the right to liberty or of the proportionality requirement after exhausting the ordinary remedies, and the Court examines a prolonged measure for proportionality and for the reasons given at each review. Our practice page on criminal law in Turkey covers the objection and appeal system in general.
Breach: arrest for non-compliance and loss of the security
The sanction for breach is detention. Where the suspect or accused wilfully fails to comply with the obligations, the competent judge or court may order detention at once, whatever the length of the sentence the offence carries, so that a person charged with an offence for which detention would otherwise be prohibited can be detained for breaching the control measure imposed in its place. The word that matters is wilfully: a missed signature caused by illness, a court date in another city or an error in the decision is not a wilful breach, and the defence proves it with documents filed before the prosecutor's request is decided. Where judicial control had been imposed because the maximum period of detention had expired, a later detention for breach is itself limited, to nine months in high criminal court cases and two months in others.
The breaches that lead to detention in practice are a departure or an attempted departure from the country, repeated missed signatures without explanation, contact with a protected person, and the removal of an electronic tag. Each is reported by the police or the probation directorate to the prosecutor, who applies to the judge; the person is heard before detention is ordered unless they cannot be found, and the hearing is the place to produce the hospital record, the boarding pass of the domestic flight or the message log that shows the contact was initiated by the other side. A person who has left Turkey in breach and wishes to return is advised to return through counsel with an explanation and an offer of increased security filed before arrival, because an arrest at the border on a warrant issued for breach leads to detention without that hearing.
Security is lost on the same facts. A failure to meet the attendance obligations without a valid excuse forfeits the security to the Treasury under the rules described above, and the forfeiture is ordered by the court with the detention or separately; a valid excuse keeps it. Our note on Interpol Red Notices and extradition in Turkey describes what follows when a person under judicial control leaves and the Turkish court issues a warrant that is circulated abroad.
Foreign nationals: custody, consular notification, residence status and leaving Turkey
A foreign suspect usually meets judicial control at the end of police custody. Custody lasts up to twenty-four hours from arrest, excluding travel time to the nearest judge, and can be extended for offences committed collectively, so that the person is before the judge within one to four days; the police must inform a relative or a person the suspect designates, and under the Vienna Convention on Consular Relations and Turkish practice a foreign detainee is told of the right to have the consulate notified, and the consulate is informed if the person asks. The suspect is entitled to an interpreter at the police station, before the prosecutor and before the judge, and to a lawyer at every stage; in our practice the decisive documents for the hearing, the residence permit, the lease, the employer's letter and the passport, are collected by counsel from the family or the consulate during custody, because the judge decides on what is in the file that day.
Judicial control affects immigration status in two directions. A foreign national under a travel ban must stay in Turkey, but the ban does not by itself give a right to stay: a visitor whose visa or visa-free period runs out needs a residence permit, and the Law on Foreigners and International Protection provides a short-term permit for persons required to remain in Turkey by a judicial or administrative decision, applied for at the provincial migration directorate with the court's decision as the ground, which in our files is filed as soon as the ban is ordered so that the person is not an overstayer when the case ends. In the other direction, a conviction may lead to a removal decision and an entry ban under the same law, so the plea and sentencing strategy in the criminal case is set with the immigration consequence in view, and a foreign resident with a family and a business in Turkey weighs a suspended sentence differently from a visitor. Our practice page on the Turkish immigration lawyer covers residence permits and removal decisions.
When the case ends, the measures end with it: judicial control ceases on acquittal, on a decision not to prosecute and on the judgment becoming final, and the court's letter lifting the travel ban is sent to the police and the border system, which in practice takes days rather than hours, so a person who intends to leave immediately after the judgment asks for the lifting order in writing and carries it. A bank account frozen as part of the same investigation is a separate measure with its own release procedure, as our note on bank account freezes in Turkey explains. Our practice page on the residence permit lawyer in Turkey covers the permit a foreign suspect needs while the case runs.
Frequently asked questions
- What is judicial control in Turkey and how does it differ from detention? Judicial control is a set of obligations, such as a travel ban, reporting to a police station, security or house arrest, that a judge orders instead of pre-trial detention where the grounds for detention exist but liberty under conditions is enough. A detention order must state why judicial control would be insufficient.
- Which measures can the judge impose? The ones the Code lists: a ban on leaving the country, regular reporting, compliance with summonses and work or education conditions, a driving ban with deposit of the licence, treatment for addiction, security, a weapons ban, security for the victim's rights, an undertaking on family obligations and maintenance, house arrest, a residential-area restriction and a ban on going to certain places, alone or combined.
- How long can judicial control last? Two years, extendable by one, in cases outside the high criminal court; three years, extendable by up to three, or up to four for terrorism and constitutional-order offences, in high criminal court cases; half for children. The need for each measure is reviewed at least every four months, and the Constitutional Court has held that time on appeal counts.
- Can I object to or change a judicial control decision? Yes. You may ask at any time for a measure to be lifted or changed, with a decision due within five days after the prosecutor's opinion, and you may object to any decision within two weeks of learning of it, to the authority that gave it, which passes the objection to the reviewing judgeship or court.
- What happens if I breach a judicial control measure? A wilful breach allows the judge or court to order detention at once, whatever sentence the offence carries, and the security is forfeited to the Treasury unless there is a valid excuse. A documented excuse filed at once, such as hospital admission, is not a wilful breach.
- Can a foreign national under a travel ban leave Turkey for an emergency? Only with the judge's or court's written permission on an application stating the reason, dates and return, which is granted rarely and usually against increased security. Leaving without permission is treated as flight and leads to a warrant.
- Do I need a residence permit while under a travel ban? Yes if your visa or visa-free period runs out. The travel ban obliges you to stay but does not authorise the stay; the Law on Foreigners provides a short-term residence permit for persons required to remain in Turkey by a judicial decision, applied for with the court's decision.
