⚖️ Criminal Defense Lawyer in Turkey
A criminal defense lawyer in Turkey defends individuals facing arrest, detention, investigation or prosecution, from the first police contact to final appeal.
If you are reading this, one of two things has probably happened. Either you have had contact with Turkish police, a prosecutor or a court and you are trying to understand what comes next, or someone close to you has been detained in Turkey and you are searching from another country for a way to help. Both situations share the same problem: the case is already moving, and it does not pause while you find your footing.
Most people who contact our criminal defense lawyers did not plan to need one. They were travelling, working or living in Turkey when something shifted. A police stop that became a detention. A business dispute that a former partner reframed as fraud. A border crossing that produced an arrest warrant nobody knew existed. By the time the situation is understood well enough to explain it to a family member abroad, some of the most consequential decisions in the file have already been made, usually by someone else.
What is the single most important thing to do in the first hours after an arrest in Turkey? Say nothing until a lawyer is beside you. Silence is the most active step available to you in the first twenty four hours, because under Article 150 of the Code of Criminal Procedure (CMK No. 5271) you have the right to counsel before any questioning begins, and a statement given without that protection becomes part of the file permanently. Not answering is not obstruction. It is the one procedural right that costs nothing to use and cannot be recovered once spent.
The reason this matters more in Turkey than many foreign nationals expect is structural rather than cultural. Turkish criminal procedure front-loads the decisive work. The prosecutor builds the file, the Criminal Court of Peace reviews detention, and the trial court later examines a record that was largely assembled before anyone stood in a courtroom.
Which stage of a Turkish criminal case does defense counsel change the most? The stage where there is not yet a case. Once an indictment exists, the defense argues about a record; before it exists, the defense can still shape what goes into that record, which is why the police station matters more than the courtroom in outcome terms. A defense built at trial is often only the echo of choices made in a corridor months earlier.
As a foreign national you also carry an exposure Turkish citizens do not. Language is the visible part of it. A sworn interpreter is provided at no cost under Turkish law, but an interpreter translates words, not context, and a sentence that sounds cooperative in one language can read as an admission in another (this is not a translation quality problem, it is a legal register problem, and it shows up in the file long after the interview has ended).
The less visible part is that a criminal case in Turkey rarely stays a single case. It can affect your residence permit, trigger a deportation review and sit alongside an international notice at the same time. Three proceedings, three separate authorities, and none of them waits for the others to finish.
When should a family abroad contact a lawyer in Turkey after a relative is detained? The same day, before the twenty four hour custody window closes. Distance does not close your options, delay does: a criminal defense lawyer inside Turkey can identify the facility, communicate with the authorities, confirm that the consulate was notified and file an objection at the first available hearing, and every one of those steps has a deadline attached to it.
Who decides whether you stay in custody while the case continues? A judge at the Criminal Court of Peace, on the basis of the file as it stands at the twenty four hour mark, not on the basis of the eventual verdict. This is why the first day of a case and the last day of a case are decided by two different bodies working from two very different amounts of information.
Oznur & Partners provides criminal defense services throughout Turkey, representing individuals and foreign nationals during police investigations, detention proceedings, prosecutions and criminal trials, including matters with an extradition or international dimension.
⚖️ Have You or a Family Member Just Been Arrested in Turkey?
If an arrest has just happened, four rights matter immediately and each of them can be lost by not using it. You have the right to remain silent until a lawyer is present. You have the right to counsel before questioning under CMK Article 150. You have the right to a sworn interpreter at no cost. You have the right to have your consulate notified of your detention.
These rights exist in law, but they do not enforce themselves. If you do not know them, or waive them under pressure in a room where everyone else speaks the language and you do not, you hand the prosecution material that cannot be taken back later.
Under CMK Article 91, police detention without a judicial order is limited to 24 hours, extendable to 48 hours with prosecutor approval, and up to four days for offenses connected to organized crime or terrorism. After that window the prosecutor must either release you or bring the matter before a Criminal Court of Peace. The 24 hour mark is not an administrative formality. It is the structural deadline that shapes the trajectory of everything after it.
If it is your family member who has been detained, you are not powerless from abroad. How much can a lawyer actually do while the family is in another country? Almost everything that matters in the first days, because the steps that count are procedural rather than personal: locating the police station, prosecutor’s office or courthouse handling the matter, communicating with the authorities, attending procedural actions, verifying consular notification, and filing objections or release requests where the law allows. What a family abroad cannot do is any of those things, and that gap is the reason the first phone call is usually worth more than the next three weeks of searching.
One practical note that costs nothing. Write down the date, the approximate time and the place of the detention, and the name of any authority mentioned. In a system where deadlines run in hours, that small amount of information often determines how quickly counsel can locate the file.
⚖️ Why Do the First 24 Hours Decide the Outcome?
In Turkish criminal practice the first 24 hours are the most consequential window in the entire case. Three things happen, or fail to happen, inside it, and each one narrows or widens everything that follows.
First, the initial statement is recorded. Under Turkish law that statement is admissible only if counsel was present and the right to an interpreter was honored. Contesting a statement that already exists is considerably harder than preventing one that should never have been given, and the difference between those two positions is usually a single phone call.
Second, the prosecutor decides whether to seek pre-trial detention. That decision rests on the file as it stands at the 24 hour mark. Evidence, documentation and procedural objections filed inside the window become part of the record the Criminal Court of Peace reviews. Anything submitted afterwards is weighed against the initial decision rather than in place of it, which is a much weaker position to argue from.
Third, the investigation gains momentum. Searches, seizures, digital forensics and witness interviews carried out in the first day produce the raw material for the eventual indictment. Defense counsel present during this period can attend searches, note procedural irregularities and preserve objections that are otherwise lost by the time anyone thinks to raise them.
Does waiting a day or two before calling a lawyer really change anything? Yes, and rarely in a way that is visible at the time. A delay of a few hours is not just a delay; it is a quiet narrowing of the options available at every later stage. By the time a case reaches a courtroom the factual record is largely fixed: the witnesses have spoken, the forensic reports are written, the detention decision has been made and reviewed at least once.
Is someone in custody right now, with the 24 hour clock already running?
Tell us the city, the approximate time of detention and the nationality of the person held. That is usually enough to begin locating the file today.
⚖️ Three Files, Not One: The Cases That Open Behind a Criminal Case
For a foreign national, a Turkish criminal accusation almost never stays a single proceeding. It opens a criminal file, and behind it, quietly and on their own timetables, up to two more.
The first file is the one everybody sees: the investigation and prosecution, run by the public prosecutor and decided by a criminal court. The second file is administrative. Provincial migration authorities can review your residence status independently of the criminal court, and under Article 54 of the Law on Foreigners and International Protection (Law No. 6458) certain outcomes produce a deportation decision and, in some cases, a re-entry ban. The third file exists only in some matters and is international: an extradition request, or an Interpol notice circulating in databases you cannot see.
Three authorities, three sets of rules, three timetables. None of them pauses to see what the others decide. This is the part that surprises even sophisticated clients, and it is the reason a defense strategy that accounts only for the courtroom is structurally incomplete.
The practical consequences are specific rather than theoretical:
- A criminal outcome that looks favorable, such as a suspended sentence, can still trigger an independent administrative review of your residence permit.
- A negotiated resolution that shortens the criminal exposure may leave the deportation exposure untouched, because the migration authority reads the conviction, not the negotiation.
- An acquittal in Turkey does not automatically delete an Interpol notice, which is administered by a body outside Turkish jurisdiction entirely.
- Time spent focused on one file can allow a deadline to pass unanswered in another, and administrative deadlines are short.
Can a case end well in the criminal court and badly everywhere else? Yes, and it happens often enough that we treat it as the default risk rather than the exception. The criminal court decides guilt. It does not decide whether you may continue living in Turkey, whether you may re-enter, or whether a notice in Lyon stays active. Those questions belong to other authorities and have to be worked in parallel from the beginning, not retrieved afterwards.
The measure of a criminal defense is therefore not only the verdict. It is what the case leaves behind: where you can live, where you can travel, and whether the file follows you across a border years later.
⚖️ How a Criminal Defense Lawyer Protects You at Each Stage
The work of a criminal defense lawyer is not limited to appearing in court. It begins at the first point where a procedural decision can be made, because each of those decisions either opens or closes options for the defense.
During the investigation phase, the work is attending police questioning with you, reviewing the case file as access permits, challenging unlawful searches or seizures, and making sure no statement is given without proper legal protection. This is unglamorous work and it is where cases are most often won or quietly lost.
At the detention review, the work changes shape. Counsel argues before the Criminal Court of Peace for release, or, more realistically in many foreign national cases, for the least restrictive measure available instead of custody. The argument at this hearing is not about innocence. It is about flight risk, evidence tampering risk and proportionality, and it needs to be prepared as a separate case with its own evidence.
At trial, the work is cross-examining witnesses, challenging the prosecution’s evidence, testing the categorization of the charge, and building the structural argument the court needs in order to reach an acquittal or a reduced finding.
Running alongside all of it is the second track described above: the residence permit review, the deportation risk, the re-entry restriction, and where relevant the extradition or Interpol dimension. In practice these are handled by different lawyers within a team, on different timetables, and the coordination between them is itself part of the defense.

⚖️ The Charge Against You: What It Means for Your Defense
The charge shapes everything that follows: which court hears the case, the sentence range, the likelihood of pre-trial detention, and where the defense has to concentrate its effort. The matters below arise most often in cases involving foreign nationals, cross-border elements and serious accusations under the Turkish Penal Code (TCK No. 5237).
- Drug offenses and trafficking under TCK Articles 188 to 192
- Financial crimes, fraud and money laundering
- Cybercrime and digital offenses
- Organized crime and conspiracy charges
- White collar offenses and corporate criminal liability
- Violent crimes and personal injury cases
- Sexual offenses
- Document-related offenses, including forged or altered official documents
- Extradition proceedings and Interpol Red Notice challenges
Drug Offenses Under TCK Articles 188 to 192
A drug-related charge is among the most serious situations a foreign national can face under Turkish law. The sentencing structure is aggressive compared with many other jurisdictions, and courts may treat cross-border movement as an aggravating factor under TCK Article 188, paragraph 4.
| Offense Category | Article | Base Sentence | Aggravating Factors |
|---|---|---|---|
| Manufacture or trafficking | TCK 188/1 | 20 to 30 years plus heavy fine | International element, organized group |
| Trafficking of heroin, cocaine, synthetic drugs | TCK 188/4 | Base sentence increased by half | Cross-border movement, high quantity |
| Facilitation of drug use | TCK 190 | 5 to 10 years | Involvement of minors, public spaces |
| Use and possession | TCK 191 | 2 to 5 years, diversion possible | Prior convictions, quantity above personal use |
Defense in a drug case turns on three questions: whether the physical evidence was lawfully obtained, whether the chain of custody is intact, and whether your role was correctly categorized. That last question carries the most weight in sentencing terms. The distance between possession under TCK 191 and trafficking under TCK 188 is the distance between a diversion programme and two decades, and the categorization is frequently arguable on the facts.
Extradition and Interpol Red Notice Defense
Turkey is a party to the European Convention on Extradition and has bilateral extradition treaties with a significant number of countries. Extradition proceedings do not assess guilt. They assess whether the legal conditions for transfer are met, which is a narrower and more technical question than most people expect, and they run on their own deadlines.
The most common entry point for foreign nationals is an Interpol Red Notice. A Red Notice is not an arrest warrant. It is a request for provisional arrest pending extradition, and it can be challenged before the Commission for the Control of Interpol’s Files (CCF) in Lyon on grounds including political motivation, abuse of process and non-compliance with Interpol’s own constitution.
Why do these two proceedings have to be run together rather than one after the other? Because a result in one does not bind the other. The CCF can delete a notice while a Turkish extradition file remains open, and a Turkish court can refuse transfer while the notice continues to circulate and stop you at a third country’s border. Coordinated work across both tracks produces stronger outcomes than either pursued alone, and the sequencing of the two applications is itself a strategic decision.
⚖️ What Happens Next? Turkish Criminal Procedure from Detention to Verdict
If you or someone close to you is already inside the system, knowing what comes next removes some of the fear of the unknown and shows where a defense can still change direction. Turkish criminal procedure moves through defined stages, and the quality of intervention at each one affects the outcome directly.
Stage 1, Investigation (Soruşturma): the process begins when a prosecutor opens an investigation. Suspects may be detained for questioning. Under CMK Article 91 police detention is limited to 24 hours without a judicial order, extendable in specific circumstances. An attorney must be present before any statement is given.
Stage 2, Detention and Custody Hearing: if the prosecutor requests pre-trial detention (tutukluluk), a Criminal Court of Peace (Sulh Ceza Hakimliği) reviews the request within 24 hours. Defense counsel presents arguments against detention at this hearing. The difference between remand and release at this stage shapes every step that follows, including how effectively you can participate in your own defense.
Stage 3, Indictment (İddianame): if the investigation produces sufficient evidence, the prosecutor prepares a formal indictment. The defense reviews it, challenges inadmissible evidence and finalizes strategy. This is the first time you face a structured accusation rather than scattered questions.
Stage 4, Trial (Yargılama): criminal cases are heard before Criminal Courts of First Instance (Asliye Ceza Mahkemesi) for lesser charges, or High Criminal Courts (Ağır Ceza Mahkemesi) for serious offenses. The defense presents arguments, examines witnesses and challenges prosecution evidence.
Stage 5, Appeal (İstinaf and Temyiz): verdicts can be appealed first to the Regional Courts of Appeal (Bölge Adliye Mahkemesi) and then to the Court of Cassation (Yargıtay). In cases involving human rights violations, applications to the Constitutional Court and subsequently the European Court of Human Rights remain available.
Asliye Ceza and Ağır Ceza: Which Court Hears Your Case
| Court | Jurisdiction | Bench | Typical Sentence Range | Example Offenses |
|---|---|---|---|---|
| Asliye Ceza Mahkemesi | Upper limit up to 10 years | Single judge | Up to 10 years | Simple fraud, minor assault, property damage, drug use under TCK 191 |
| Ağır Ceza Mahkemesi | Offenses above 10 years, aggravated cases | Three judge panel | 10 years to aggravated life | Drug trafficking under TCK 188, aggravated fraud, organized crime, homicide |
The jurisdictional line is drawn by the upper limit of the possible sentence, not by the sentence the prosecutor actually seeks. That distinction is worth pausing on, because it means an argument about how the charge is categorized at the indictment stage can move the case to a different court with a different bench structure before a single witness is heard.
For the official text of Turkish criminal law you can consult the Turkish Penal Code (TCK No. 5237) through the official Turkish legislation database.
⚖️ Can You Avoid Detention? Judicial Control Measures
Pre-trial detention is not the only possible outcome. Under CMK Article 109 courts can apply a range of judicial control measures (adli kontrol) designed to secure your presence without physical custody. At the first custody hearing the strongest defense argument is often not about release in the abstract, but about substituting a specific, verifiable, less restrictive measure for detention.
| Measure | Legal Basis | Restriction Level | Typical Use |
|---|---|---|---|
| Pre-trial detention (Tutukluluk) | CMK 100 to 108 | Physical custody | Serious offenses, flight risk, evidence tampering risk |
| Travel ban (Yurt dışı çıkış yasağı) | CMK 109/3(a) | Cannot leave Turkey | Foreign nationals where departure abroad is the main concern |
| Residence restriction | CMK 109/3 | Must remain in designated area | Cases where presence at a specific location is relevant |
| Regular signing at police station | CMK 109/3(b) | Periodic reporting | Lower risk cases requiring monitoring |
| Surrender of passport or ID | CMK 109/3(c) | Travel documents held by court | Common for foreign nationals alongside a travel ban |
| Electronic monitoring | CMK 109/3(j) | Tracked movement | Alternative to detention in specific cases |
| Security deposit (Güvence bedeli) | CMK 113 | Financial guarantee | Usually combined with other measures |
Courts frequently grant a travel ban combined with passport surrender as an alternative to detention where the defense presents a credible argument against flight risk. For a foreign national this is often the realistic target at the first custody hearing: not immediate freedom to leave, but the least restrictive combination of measures that keeps you outside a detention facility while the case proceeds.
Where is a custody hearing actually won? Outside the courtroom, in the hours before it, through documented ties to Turkey presented as evidence rather than described as argument. A registered address, a lease, employment or a company registration, family present in the country, a surrendered passport already in the file: these are the materials the court weighs against flight risk, and assembling them is work that has to be done in the hours before the hearing, not argued in the abstract inside it.
⚖️ When Should You Contact a Criminal Defense Lawyer in Turkey?
Earlier than most people do. The moment at which legal help becomes valuable is not the moment charges are filed; it is the moment a criminal process becomes possible.
Situations where contacting a criminal defense lawyer is already justified:
- You have been detained, questioned or invited to a police station or prosecutor’s office for any reason.
- You have received a written summons (davetiye) and do not know whether you are named as a suspect, a witness or a complainant.
- A complaint has been filed against you, even if no authority has contacted you yet.
- A commercial or personal dispute has begun to be described in criminal terms by the other side.
- You have been stopped at a border or airport and told there is a record attached to your name.
- You are planning to leave Turkey while any investigation involving you is open.
- A family member abroad has lost contact with you and you are in custody.
The last two deserve particular attention. Attempting to leave Turkey while a travel ban is in force creates fresh criminal exposure on top of the original matter, and it converts a defensible case into a case that also has to explain a departure. A five minute check of your legal status through counsel is inexpensive compared with what an incorrect assumption costs at passport control.
Is it too late to involve a lawyer after a statement has already been given? No, but the work changes from prevention to repair. A statement taken without counsel present, without a sworn interpreter, or without proper notification of rights can be challenged on admissibility grounds, and those challenges succeed more often than people assume. It is simply a harder position than the one available a day earlier.
⚖️ How to Choose a Criminal Defense Lawyer for a Case in Turkey
Families searching from abroad usually have hours rather than weeks to make this decision, often in a language they do not read, from a list they cannot verify. A few criteria narrow the field quickly.
Bar registration, verified independently. Every licensed attorney in Turkey is registered with a local bar association and holds a registration number. Credentials for Istanbul based lawyers can be checked through the Istanbul Bar Association registry. Confirm this before anything else, and confirm it yourself rather than accepting a screenshot.
Experience with the specific charge, not criminal law generally. Drug trafficking, financial crime and extradition are three different practices with three different evidential landscapes. Ask which of them the lawyer has handled recently.
Capacity on the second and third file. If the firm cannot describe how the residence permit and deportation exposure will be handled alongside the criminal case, the case is being viewed too narrowly for a foreign national.
A written engagement and a clear fee structure. The Turkish Union of Bar Associations publishes minimum tariff guidance annually, but actual fees are agreed between client and attorney in writing. A firm that will not put the arrangement in writing before representation begins is telling you something useful.
Direct communication in a language you follow. Not a translated summary three days later. In a case where deadlines run in hours, communication delay is a legal risk rather than a comfort issue.
One warning worth stating plainly. Nobody can promise an outcome in a criminal case, and a promise of one is itself a reason to walk away. What can be promised is presence at the moments that matter, and that is a more useful commitment than confidence.
⚖️ Consular Notification: What Your Embassy Can and Cannot Do
Under the Vienna Convention on Consular Relations (1963), a foreign national detained in Turkey has the right to have their consulate notified, and the consulate has the right to visit, communicate and assist in arranging legal representation.
Notification is sometimes delayed or incompletely recorded in practice. One of the first tasks of defense counsel is to verify that it actually happened and that it appears properly in the file, because a gap there can become the basis of a procedural challenge later (and because families abroad frequently learn of a detention through the consulate rather than from the detained person, who may have had no opportunity to call anyone).
What a consulate can do: visit you in detention, communicate with your family, provide a list of local lawyers, monitor detention conditions and raise welfare concerns with the authorities.
What a consulate cannot do: act as your defense lawyer, intervene in the substance of the case, negotiate with Turkish prosecutors, secure your release, or pay legal fees. Consular presence accelerates communication and verification. The defense itself is carried by retained Turkish counsel, and the coordination between the two is part of normal case management for foreign nationals.
⚖️ If You Are a Foreign National Facing Charges in Turkey
Facing criminal proceedings in Turkey as a foreign national means dealing with more than the charge itself. Language, unfamiliarity with Turkish criminal procedure and the absence of a local support network each add legal risk at every stage, and they compound rather than simply add.
Under the Code of Criminal Procedure (CMK No. 5271) you have the right to be informed of the charges in a language you understand, to a sworn interpreter at no cost, and to have your consulate notified upon detention. Each of these rights can fail in practice if it is not actively enforced, which is why counsel present from the first moment matters as much as the rights themselves.
Our criminal defense lawyers have represented clients from Europe, the Middle East, Central Asia and North America in proceedings across Istanbul. What appears from the outside to be a routine detention is frequently the moment three separate timetables begin running at once: the investigation, the detention review and your own residence or visa status.
Where the case has a cross-border element, the picture widens again: evidence located in another country, a home jurisdiction proceeding on related facts, or a notice circulating internationally. Handling these coherently is a coordination problem before it is a legal one.

⚖️ About Oznur & Partners Criminal Defense Practice
Oznur & Partners is an Istanbul based law firm serving foreign nationals across Turkish criminal, corporate, real estate and investment law. The firm is led by attorney Fatih Oznur, and our team is registered with the Istanbul Bar Association, where our credentials can be verified directly through the official registry.
What distinguishes criminal defense work for foreign clients is not only knowledge of Turkish law, but the capacity to run a case across jurisdictions and in the client’s own language without losing nuance in either direction. That capacity is built case by case, over years, and it is the reason our criminal defense practice concentrates on matters where a foreign element shapes the strategy rather than merely complicating it.
For the people involved, a criminal trial is rarely just a legal event. It is a turning point that touches residence status, business continuity and family planning at the same time. We are often contacted by families rather than by the accused, in the hours when nobody yet knows which authority is holding whom, and the first work is usually simply finding the file.

⚖️ The Case Is Already Moving
This page opened with a simple observation: the case does not pause while you find your footing. That is the whole of it. Turkish criminal procedure is not designed to wait for understanding to catch up with events, and the hours in which the file takes its shape are the hours in which almost nobody has a lawyer yet.
Everything above describes the same thing from different angles. The 24 hour window. The three files that open behind one accusation. The difference between a control measure and a cell. None of it requires you to become an expert in Turkish criminal law. It requires one decision, made early, by someone who still has the option to make it.
If that decision is in front of you now, the useful thing to know is that the first call is short. What is the city, when did it happen, and who is being held. The rest is our work.
