Criminal Defense Lawyer in Turkey | Istanbul Law Firm

When Justice Fails, Strategy Begins

Facing criminal charges in Turkey can turn a person’s life upside down in a moment. Arrest, investigation, and court proceedings often begin before the situation is fully understood — especially for foreign nationals unfamiliar with the legal system.

Sometimes, people find themselves trapped in the legal system not because they are guilty, but because the system made a mistake. In Turkey, serious criminal charges can escalate quickly, and decisions made in the first hours of detention can shape the entire outcome of a case.

When justice fails, what matters is not only knowing the law, but understanding how to act within it at the right moment and with the right strategy. A criminal defense lawyer is not merely a representative in court. They are the architect of your defense — analyzing procedural risks, tracking inconsistencies, and building a structure strong enough to withstand pressure.

Criminal Defense Lawyer in Istanbul for Foreign Nationals

For foreign nationals, criminal proceedings in Turkey present a distinct set of challenges that go beyond the charges themselves. Language barriers, unfamiliarity with Turkish criminal procedure, and the absence of a local support network can each compound the legal risk at every stage.

Under Turkish law, specifically the Code of Criminal Procedure (CMK No. 5271), foreign nationals have the right to be informed of their charges in a language they understand, to access an interpreter at no cost, and to have their consulate notified upon detention. These rights exist in statute — but exercising them in practice requires a lawyer who is present from the very first moment.

Our legal team at Öznur & Partners has represented clients from Europe, the Middle East, Central Asia, and North America in criminal proceedings across Istanbul. We understand how the system works, where it creates risk for foreign nationals, and how to intervene before that risk becomes irreversible damage.

Istanbul: A City of Secrets and Trials

In a city that has witnessed empires rise and fall, the courtroom is just another battlefield where fate is decided. Istanbul’s criminal justice system is layered, nuanced, and sometimes unpredictable. Language barriers, cultural differences, and legal complexity often create invisible traps for foreign nationals. What appears manageable at first can quickly become difficult to control without proper legal guidance.

That is why your lawyer must do more than translate documents. They must translate your story into a legal language that resonates with the court.

Whether it is your first time dealing with the law in Turkey or you have already faced legal proceedings, we stand ready to protect your rights at every stage.

Serious Criminal Charges Require Serious Minds

Drug trafficking. Money laundering. Organized crime. Fraud. Cybercrime. These are not just legal terms — they are life-altering accusations. Under the Turkish Penal Code (TCK No. 5237), such charges carry heavy prison sentences and demand an immediate, calculated response.

Our approach combines legal expertise with analytical precision. Every detail matters. Every second counts.

From the very first moment of detention or investigation, the legal process begins to take shape. Statements given early, interactions with law enforcement, and procedural steps taken without proper legal support can define the entire case. That is why early legal intervention is not optional. It is critical.

We handle criminal defense across the full spectrum of Turkish criminal law, including:

Drug offenses and trafficking under TCK Articles 188–192
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
Extradition proceedings and Interpol red notice challenges

How Criminal Defense Works in Turkey: From Detention to Verdict

Understanding the structure of Turkish criminal procedure is essential to understanding how defense strategy is built. The process follows defined stages, and the quality of legal intervention at each stage directly affects the outcome.

Stage 1 — Investigation (Soruşturma): The process begins when a prosecutor opens an investigation. During this phase, suspects may be detained for questioning. Under CMK Article 91, police detention without a judicial order is limited to 24 hours, extendable to 48 hours in certain 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. The defense lawyer presents arguments against detention at this hearing. This is one of the most critical intervention points in the entire process.

Stage 3 — Indictment (İddianame): If the investigation produces sufficient evidence, the prosecutor prepares a formal indictment and sends the case to trial court. Defense lawyers review the indictment, challenge inadmissible evidence, and prepare the defense strategy.

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 / 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 or the European Court of Human Rights remain available options.

Your Silence Is Not Enough — Let Us Speak for You

Police custody can be overwhelming, especially for those unfamiliar with the system. Long interrogations, aggressive questioning, and the absence of proper translation often lead to misunderstandings that cause serious and lasting damage.

As criminal defense lawyers, we ensure your rights are protected from the very first moment. We intervene early, stay by your side, and make sure that no one misuses your silence as an admission.

We have seen cases where silence was misinterpreted, and where rushed statements created irreversible damage. Our job is to prevent that. Your defense starts not in the courtroom — it starts in the police station.

From the Shadows to the Courtroom

A powerful defense does not begin in the courtroom. It begins behind the scenes. We collect evidence, challenge assumptions, and anticipate the prosecution’s strategy before the first hearing.

Every case has hidden dimensions. We explore them. We expose them. And we use them to build a defense that goes beyond appearances.

Our attorneys are registered with the Istanbul Bar Association, and you can verify their credentials directly through the official bar registry. Transparency in legal representation is not optional — it is the foundation of trust.

We Defend More Than Cases — We Defend Futures

For us, a criminal trial is never just a legal event. It is a turning point in someone’s life. That is why we treat every case with the weight it deserves.

If you are facing serious criminal charges in Turkey, we are ready to act swiftly, strategically, and relentlessly on your behalf. Because when justice hesitates, we move.

Frequently Asked Questions: Criminal Defense in Turkey

What are my rights if I am arrested as a foreign national in Turkey?

Under Turkish law and international consular conventions, you have the right to be informed of the charges against you in a language you understand, to remain silent until your lawyer is present, to access an interpreter at no cost, and to have your consulate notified of your detention. These rights apply from the moment of arrest. Exercising them effectively requires immediate legal representation — your lawyer must be contacted before any statement is given to police or prosecutors.

How long can I be held in police detention in Turkey without being charged?

Under CMK Article 91, standard police detention is limited to 24 hours from the time you are brought to the police station. This can be extended to 48 hours upon prosecutor approval in certain circumstances, and up to four days for offenses related to organized crime or terrorism. After this period, the prosecutor must either release you or request pre-trial detention from a Criminal Court of Peace. A defense lawyer can challenge both the detention itself and any extension requests at each stage.

Can a foreign national be deported after a criminal conviction in Turkey?

Yes. A criminal conviction in Turkey can trigger deportation proceedings for foreign nationals, and in some cases a re-entry ban may also be imposed. The immigration consequences of a criminal case are often as significant as the criminal penalty itself. This is why defense strategy for foreign nationals must account for both the criminal outcome and its immigration implications from the very beginning of the case.

What is the difference between pre-trial detention and a travel ban in Turkey?

Pre-trial detention (tutukluluk) means physical custody — you are held in a detention facility while the case proceeds. A travel ban (yurt dışı çıkış yasağı) is a less restrictive measure that allows you to remain free but prohibits leaving Turkey. Both are judicial control measures available under CMK Article 109. A defense lawyer can argue for the least restrictive measure — and in many cases, for full release — at the initial custody hearing before the Criminal Court of Peace.

What happens if I cannot speak Turkish during police questioning or at trial?

Turkish criminal procedure requires that all proceedings involving a person who does not speak Turkish be conducted with the assistance of a sworn interpreter, provided at no cost to the defendant. If you were questioned without an interpreter, or without being properly informed of your rights, those procedural violations can form the basis for challenging the admissibility of any statements made during that interrogation. This is a significant but often overlooked defense tool in cases involving foreign nationals.

Can Turkey extradite a foreign national to another country?

Yes. Turkey is a party to the European Convention on Extradition and has bilateral extradition treaties with a number of countries. Where a foreign state requests the extradition of a person in Turkey, the request is reviewed by the Turkish Ministry of Justice and referred to the competent court, which assesses conditions including dual criminality and whether the offense is political in nature. Defense in extradition proceedings requires specific analysis of the applicable treaty alongside Turkish extradition law, and must begin as early as possible once a request is initiated.

How do I verify that a criminal defense lawyer in Turkey is properly licensed?

Every licensed attorney in Turkey must be registered with a local Bar Association and hold a unique bar registration number. You can verify any lawyer’s credentials through the Istanbul Bar Association’s official registry at istanbulbarosu.org.tr. Reputable firms will provide this information transparently. You should always confirm credentials independently before engaging any legal representative, regardless of how they present themselves online or in person.
