Criminal Defense Law in Turkey | Immediate Representation & Litigation
Your freedom and reputation are on the line. Facing criminal charges in a foreign legal system demands more than just a lawyer; it requires an aggressive, strategic defense shield.
Being accused of a crime in Turkey is a daunting experience for any foreign national. The Turkish Penal Code (TCK) is rigorous, and a simple misunderstanding or language barrier during the initial police interrogation can lead to severe restrictions on your liberty. As Istanbul Attorneys, we act as your immediate defense force. From the moment of detention (Gözaltı) to high-stakes trials in Heavy Penal Courts (Ağır Ceza), our team ensures your procedural rights under the Code of Criminal Procedure (CMK) are fiercely protected against unlawful accusations.





Strategic Defense in Complex Criminal Cases​
​
The Turkish justice system operates on a strictly inquisitorial basis. Unlike in some Western jurisdictions, the evidence collected during the initial investigation phase (Soruşturma) often dictates the final verdict. Prosecutors have vast powers, and without immediate legal intervention, a temporary detention can quickly escalate into a pre-trial arrest order (Tutuklama) that lasts for months. At Istanbul Attorneys, we provide comprehensive defense services rooted in a deep understanding of the Criminal Procedure Code (CMK).​
​
The Critical First 24 Hours: Detention & Interrogation​
​
The most common mistake foreign nationals make is giving a police statement without a lawyer present, believing they can "explain the misunderstanding." In Turkish Law, your initial statement (İfade) is the backbone of the case. Anything you say can be used against you in court.
Our first line of defense is at the police station. We ensure you exercise your right to remain silent until we have reviewed the case file. We actively participate in the interrogation to prevent leading questions and procedural violations. If you or a family member has been detained, Contact our Emergency Criminal Defense Team immediately. Do not sign any document you do not fully understand.
​
Drug Offenses (TCK 188 & TCK 191)​
​
Turkey has extremely strict laws regarding narcotics. The legal distinction between "Possession for Personal Use" (TCK 191) and "Manufacturing and Trading" (TCK 188) is vital but often blurred by prosecutors. A simple possession charge can be upgraded to "trafficking" based merely on the quantity found or the way it was packaged.
For international clients, a drug conviction often leads to immediate deportation after the sentence. We challenge the evidence collection methods—such as unlawful searches without a proper warrant—to suppress evidence.
​
Violent Crimes & Self-Defense Claims​
​
Cases involving Intentional Injury (Kasten Yaralama) or Homicide often revolve around the concept of "Legitimate Defense" (MeÅŸru Müdafaa). Proving self-defense in Turkey requires establishing that the response was proportionate to the attack. Our litigation team works with forensic experts to reconstruct crime scenes and prove that our client’s actions were necessary for survival, aiming for acquittal or significant sentence reduction under "Unjust Provocation" clauses.
​
White Collar Crimes & Financial Allegations​
​
In Turkey, commercial disputes can aggressively escalate into criminal investigations. International business owners often face charges of "Qualified Fraud" (Nitelikli Dolandırıcılık) or "Abuse of Trust" (Güveni Kötüye Kullanma) stemming from failed contracts or partnership disagreements. These are not just civil matters; they carry heavy prison sentences.
Our team specializes in the intersection of commercial and criminal law. We analyze financial records, audit trails, and banking data to prove that the dispute is purely civil, aiming for a "Non-Prosecution Decision" (Takipsizlik) before the case even reaches the court.
​
High-Stakes Litigation: Heavy Penal Courts (Ağır Ceza)​
​
Cases involving sentences exceeding 10 years (such as organized crime, major smuggling, or homicide) are tried in Heavy Penal Courts. These are panels of three judges, not a single magistrate. The atmosphere is intense, and the procedural rules are unforgiving.
We deploy a "team defense" strategy for Heavy Penal cases. While one attorney handles cross-examination, another monitors the court clerk's minutes to ensure every defense argument is recorded verbatim. This attention to detail creates the solid foundation needed for future appeals.
​
Post-Conviction: Appeal (İstinaf) & Supreme Court (Yargıtay)
​
A verdict is not the end of the road. The Turkish judicial system has a robust appellate structure. If an unfavorable decision is reached, we immediately file an appeal to the Regional Court of Justice (BAM - İstinaf). If necessary, we escalate the case to the High Court of Appeals (Yargıtay). Timing is critical here; missing the 7-day appeal window results in the finalization of the sentence. Do not lose your right to challenge the verdict due to a procedural error.

Our Approach to Criminal Defense: Diligence & Procedure
In the Turkish legal system, the outcome of a case is often determined by procedural precision rather than courtroom drama. We focus on the strict application of the Criminal Procedure Code (CMK) to ensure a fair trial.
​
Turkish criminal law is inquisitorial, meaning the prosecutor and judge play active roles in investigating the truth. Our role as defense counsel is to ensure that this investigation remains objective, lawful, and that favorable evidence is not overlooked. We build our defense on four concrete legal pillars.

1. Pre-Trial Evaluation & Evidence Submission
The Investigation Phase (Soruşturma) is decisive. Rather than waiting passively for an indictment, we actively submit petitions and evidence to the Prosecutor's Office. Our goal is to demonstrate the lack of sufficient suspicion early on, aiming for a "Decision of Non-Prosecution" (Kovuşturmaya Yer Olmadığına Dair Karar - KYOK) whenever the file merits it.
2. Scrutinizing Expert Reports (BilirkiÅŸi)
In Turkish courts, technical matters are referred to court-appointed experts (BilirkiÅŸi). A faulty report can lead to an unjust conviction. We meticulously analyze these reports—whether they concern financial audits in fraud cases or forensic data in other matters. If we detect errors or bias, we file detailed objections and request a new expert panel to re-evaluate the evidence.

3. Protecting Your Legal Status in Turkey
For foreign nationals, a criminal conviction can trigger administrative consequences, such as deportation or visa cancellation under Law No. 6458. We view your case holistically. While defending you in penal court, we also monitor the administrative implications to protect your residency rights and ability to stay in Turkey.
4. Procedural Compliance & Statement Analysis
The Supreme Court (Yargıtay) precedents place immense weight on the initial statements given to law enforcement. We ensure that your statements were taken in accordance with the law, with a sworn translator present if needed. We challenge any procedural violations—such as prohibited interrogation methods or lack of legal counsel—to have unlawfully obtained evidence excluded from the file.
The Legal Framework: Governing Statutes of Criminal Law in Turkey
​
Turkey operates under a codified Civil Law system, distinct from Common Law jurisdictions. Criminal liability and procedural rules are strictly defined by written statutes, leaving limited room for judicial discretion compared to American or British courts. Our defense strategies are built directly upon the primary legislation governing the Turkish justice system.​
​
Primary Legislation of Criminal Law
​
-
Turkish Penal Code (TCK) No. 5237: Enacted in 2005, this is the substantive law that defines what constitutes a crime and prescribes specific penalties. It covers offenses ranging from white-collar crimes to violent felonies. [External Link] Access the full text on the Official Legislation System: Mevzuat.gov.tr - TCK No. 5237​
-
Criminal Procedure Code (CMK) No. 5271: This code governs the process of justice—from police detention and evidence collection to trial procedures and appeals. It dictates your rights during interrogation and the limits of state power. Review procedural rights: Mevzuat.gov.tr - CMK No. 5271
-
Law on the Execution of Penalties (CGTİHK) No. 5275: A prison sentence in court does not always mean time behind bars. This law regulates probation, parole, and alternative sentencing. Understanding this code is crucial for calculating the actual time likely to be served.
Constitutional & International Protections
​
-
The Constitution of the Republic of Turkey (Anayasa): Article 38 is the bedrock of criminal defense, establishing the "Presumption of Innocence" (Masumiyet Karinesi). It explicitly states that no one can be considered guilty until a final court verdict is reached. We use this constitutional right to challenge premature detentions and media trials. Read Article 38: Mevzuat.gov.tr - Turkish Constitution
-
Law on Foreigners and International Protection (YUKK) No. 6458: For non-citizens, a criminal case is never just about prison; it's about staying in the country. This law governs deportation (Sınır Dışı) procedures. Specifically, Article 54 allows the state to deport individuals considered a "threat to public order." Our defense strategy integrates this law to prevent your criminal file from becoming a deportation order. Access the Law on Foreigners
-
European Convention on Human Rights (ECHR): As a member of the Council of Europe, Turkey is bound by the ECHR. In cases where domestic remedies fail or procedural rights (such as the Right to a Fair Trial - Art. 6) are violated, we prepare the groundwork for an individual application to the Constitutional Court (AYM) and potentially the European Court of Human Rights (ECtHR).

Trusted by International Clients in Critical Moments
J.S. 🇬🇧 (United Kingdom
My son was detained at Istanbul Airport due to a misunderstanding with security. We were terrified and didn't speak the language. Istanbul Attorneys arrived at the police station within two hours. He calmed us down, handled the statement process professionally, and my son was released the same night without charges. Truly a lifesaver.
Ahmed Al-R. 🇰🇼 (Kuwait)
I faced a serious 'fraud' accusation regarding a real estate investment that went wrong. It was a nightmare; my bank accounts were frozen. Istanbul Attorneys analyzed the contracts and proved to the prosecutor that this was a civil dispute, not a crime. The case was closed with a 'Non-Prosecution' decision before it even went to court.
Dmitri V. 🇷🇺 (Russia)
After a minor altercation, I was facing not just a fine but immediate deportation. I have a family and business here. The team didn't just look at the penal code; they fought the immigration order simultaneously. Thanks to their quick injunction, my residence permit was saved. Highly recommended for foreigners in trouble.
