Scope of Our Criminal Defense Practice

Turkish criminal procedure moves rapidly once an investigation is initiated. Early intervention by an experienced defense lawyer is critical to prevent procedural errors, challenge unlawful search or seizure measures, and safeguard client autonomy. VC Law & Consultancy handles all stages of criminal proceedings under Turkish law, including representation during law enforcement questioning, prosecutor interviews, and bail hearings before the Magistrate Judgeship of Peace (Sulh Ceza Hakimliği); objections to judicial control decisions, travel bans, arrest orders, bank account freezes, and asset seizure measures; trial court representation before Heavy Penal Courts (Ağır Ceza Mahkemesi) and First Instance Criminal Courts (Asliye Ceza Mahkemesi); appellate litigation through regional appeal petitions (istinaf) and final cassation appeals before the Court of Cassation (Yargıtay); and assistance to foreign nationals facing Interpol Red Notices, provisional arrest warrants, or deportation proceedings tied to foreign criminal allegations.

Core Practice Areas and Criminal Defense Categories

Defense in Narcotics and Controlled Substance Offenses

​Turkish narcotics laws carry exceptionally strict statutory penalties and sharply distinguish between personal drug possession and illegal drug trafficking or supply. Under Article 188 of the Turkish Penal Code, the unauthorized manufacture, import, or export of narcotic or psychotropic substances is punishable by imprisonment of twenty to thirty years. Domestic acts of selling, offering for sale, transporting, storing, or commercially possessing such substances carry a sentence of not less than ten years (rising to fifteen years when the recipient is a minor), with further increases for certain substances such as heroin, cocaine, or synthetic cannabinoids, or when the offense is committed within an organized group. Personal purchase, receipt, or possession for personal use is governed by TCK Article 191 and carries a potential sentence of two to five years. First-time personal use charges frequently qualify for a deferral of the opening of a public prosecution for five years, accompanied by judicial probation and, where appropriate, treatment obligations. Defense practice focuses on analyzing search legality, questioning chain-of-custody protocols for physical evidence, and ensuring proper distinction between personal use and commercial supply allegations.

Fraud, Cyber Fraud, and Financial Crimes

Financial and white-collar crime investigations have grown increasingly complex with the rise of digital banking and international commerce. Fraud charges under Turkish law are divided into simple fraud (TCK Article 157) and qualified fraud (TCK Article 158). Qualified fraud includes offenses committed through information systems, bank accounts, insurance schemes, or by exploiting positions of trust. Unauthorized use of credit cards (TCK Article 245) and illegal access to computer systems (TCK Article 243) carry substantial prison terms. Defense work in these cases involves thorough review of financial and digital records, examination of audit logs, and representation of both individual and corporate clients.

Official and Private Document Forgery

Forgery allegations often arise in commercial disputes, property transactions, immigration procedures, or corporate governance. The Turkish Penal Code penalizes forgery in official documents under TCK Article 204 and forgery in private documents under TCK Article 207. Official document forgery carries statutory imprisonment of two to five years for private individuals, with higher penalties for public officials. Legal defense requires forensic handwriting analysis, document examination, and careful assessment of the presence or absence of criminal intent to mislead.

Assault, Intentional Injury, and Bodily Harm

Personal safety disputes, physical altercations, and domestic incidents fall under intentional injury (TCK Article 86) and aggravated injury (TCK Article 87). The law considers aggravating factors such as the use of weapons, permanent physical injury, bone fractures, or offenses committed against family members or public officials. Defense strategy centers on examination of medical forensic reports (Adli Tıp Raporu), evaluation of self-defense grounds under TCK Article 25, and clarification of the precise timeline of events.

Sexual Offenses and Abuse Allegations

Allegations concerning sexual assault (TCK Article 102), sexual abuse of minors (TCK Article 103), and sexual harassment (TCK Article 105) carry extreme legal and personal ramifications. These cases demand objective legal analysis, strict adherence to evidence evaluation rules under the Code of Criminal Procedure, and meticulous examination of witness statements, digital communications, and expert reports. Rigorous legal protection is provided while maintaining the highest level of confidentiality.

Theft, Extortion, and Property Crimes

Property offenses range from simple theft (TCK Article 141) and qualified theft (TCK Article 142) to extortion (TCK Article 148). Qualified theft involves acts committed in residential premises, at night, or using keys or electronic access. Extortion involves forcing an individual to surrender assets under threat of force or violence. Defense frequently centers on proving ownership rights, verifying value thresholds, and assessing the lawfulness of police identification and search procedures.

Defamation, Insult, and Online Cyber Harassment

Under TCK Article 125, insulting an individual’s honor, dignity, or prestige constitutes a criminal offense punishable by judicial fine or imprisonment. When defamation is committed via publicly accessible media or social networks, or is directed against public officials, statutory penalties increase. Defense strategies evaluate freedom of expression boundaries, the context of the statement, and the availability of the right to prove the truth of the statement (ispat hakkı).

Illegal Betting, Gambling, and MASAK Account Freezes

Investigation into unauthorized online betting and illegal gambling operations is regulated under Law No. 7258. Organizing or providing facilities for unauthorized sports betting, mediating money transfers for illegal betting, and promoting or advertising illegal betting platforms are criminal offenses carrying prison terms generally ranging from one to five years (with higher ranges in certain access-facilitation cases). Participating as a player is classified as an administrative misdemeanor subject to substantial financial fines. In practice, the Financial Crimes Investigation Board (MASAK) frequently issues temporary freezing orders on bank accounts suspected of involvement in illegal betting or related money transfers. Legal action is often required to challenge freezes on legitimate commercial and personal accounts and to represent individuals drawn into broader investigations.

Rights of Foreign Nationals in Turkish Criminal Proceedings

Foreign citizens involved in Turkish criminal cases have specific procedural rights designed to ensure fairness. Under CMK Article 202, any suspect or defendant who does not speak Turkish has the absolute right to a qualified interpreter during police questioning, prosecutorial interviews, and court hearings. Foreign detainees have the right to request that their home nation’s consulate or embassy be notified of their arrest or detention. A criminal charge can trigger administrative detention in a Removal Center (Geri Gönderme Merkezi) and a subsequent deportation order by the Presidency of Migration Management. Managing criminal defense simultaneously with administrative immigration defense is essential to prevent premature deportation while criminal proceedings remain pending. Release under judicial control or financial bail is available regardless of nationality, although foreign nationals may be viewed as a higher flight risk; concrete evidence of local residency, family ties, or business operations in Turkey is frequently decisive in securing release.

Questions & Answers

What should I do immediately if I am detained by the police in Istanbul?

You have the right to remain silent regarding the substance of the allegation until your legal counsel is present. Explicitly request to contact a criminal defense attorney before giving any official statement or signing any police protocol (ifade tutanağı).

What is the difference between a judicial control order and arrest?

Arrest involves physical detention in a prison facility prior to trial. Judicial control (adli kontrol) is an alternative measures framework that allows a suspect to remain free during the proceedings subject to conditions such as signature duties at a local police station, a bail deposit, or a travel ban prohibiting departure from Turkey.

Can a foreign national be released on bail in Turkey?

Yes. Turkish criminal law permits release under judicial control or financial bail regardless of nationality. Because foreign nationals may be viewed as a flight risk, defense counsel must present concrete evidence of local residency, family ties, or business operations in Turkey to support release without pre-trial detention.

How long does a criminal trial usually take in Turkish courts?

Investigation phases can last from several weeks to several months depending on evidence gathering and forensic reports. Once an indictment (iddianame) is accepted by the court, trial proceedings before First Instance or Heavy Penal Courts typically require six to eighteen months, with additional time required for appellate reviews.
