Strategic Criminal Defence and Legal Representation Throughout Türkiye

Facing a criminal investigation or prosecution can be one of the most challenging experiences for an individual or business. Whether you have been detained by the police, questioned by the Public Prosecutor, arrested, accused of a criminal offence, or summoned to appear before a criminal court, obtaining experienced legal representation at the earliest possible stage is essential to protecting your rights, reputation, and future.

At Bıçak, we provide strategic criminal defence and legal advisory services to individuals, executives, entrepreneurs, multinational corporations, financial institutions, public officials, diplomatic missions, and international organisations facing criminal matters in Türkiye. Our lawyers represent clients throughout every stage of criminal proceedings – from the initial investigation and police interviews to criminal trials, appeals, constitutional complaints, and applications before the European Court of Human Rights where appropriate.

As a full-service law firm with offices in Ankara and İstanbul, we provide criminal law services throughout the entire jurisdiction of Türkiye. We regularly represent both Turkish and international clients before Public Prosecutors’ Offices, Criminal Courts of Peace, Criminal Courts of First Instance, Assize Courts, Regional Courts of Appeal, the Court of Cassation, administrative authorities, and other competent judicial institutions. Our nationwide capability enables us to coordinate complex, multi-jurisdictional criminal matters while maintaining consistent legal strategy and client communication.

Our criminal law practice combines extensive courtroom experience with internationally recognised academic expertise. The firm is led by Professor Dr. Vahit Bıçak, one of Türkiye’s leading scholars in criminal law, criminal procedure, and the law of evidence. His academic work, publications, expert opinions, and decades of practical legal experience enable our team to deliver sophisticated legal strategies grounded in both legal theory and courtroom practice.

We understand that criminal proceedings often have consequences extending far beyond the courtroom. Allegations of criminal misconduct may affect professional licences, commercial relationships, employment, regulatory compliance, immigration status, financial assets, reputation, and international business operations. For this reason, our approach goes beyond traditional criminal defence. We work closely with our clients to identify legal risks, protect commercial interests, coordinate parallel administrative or civil proceedings, and develop practical strategies that achieve the best possible outcome under often complex circumstances.

Whether defending individuals accused of criminal offences, advising companies during internal investigations, representing victims of crime, or assisting foreign nationals involved in criminal proceedings in Türkiye, we are committed to providing responsive, discreet, and results-oriented legal representation tailored to each client’s specific objectives.

Comprehensive Criminal Law Services

Our Criminal Law Practice encompasses virtually every aspect of Turkish criminal law and criminal procedure. We advise and represent clients in relation to investigations, prosecutions, regulatory enforcement actions, corporate criminal liability, white-collar crime, financial offences, cybercrime, organised crime, violent offences, appeals, and post-conviction remedies.

Our multidisciplinary approach enables us to combine criminal defence with expertise in corporate law, regulatory compliance, financial crime, international law, cybersecurity, sanctions, anti-money laundering, and dispute resolution whenever a matter requires an integrated legal strategy.

Whether the matter concerns a straightforward criminal investigation or a complex cross-border prosecution involving multiple jurisdictions, our objective remains the same: to protect our clients’ rights, minimise legal and commercial risks, and deliver effective legal solutions based on experience, integrity, and strategic thinking.

Why This Matters

A criminal investigation should never be underestimated. Decisions made during the earliest stages of proceedings often have a significant impact on the eventual outcome of a case. Seeking experienced legal advice promptly can help preserve important rights, protect evidence, avoid procedural mistakes, and significantly improve the prospects of a successful defence. For this reason, we encourage individuals, businesses, and organisations to obtain legal advice as soon as they become aware of any criminal investigation or allegation affecting them.

Why Choose Bıçak Law Firm?

Criminal proceedings demand more than knowledge of the law. They require sound judgement, strategic thinking, courtroom experience, and the ability to anticipate legal, commercial, and reputational risks before they arise. At Bıçak Law Firm, we believe that effective criminal defence begins long before a case reaches the courtroom.

Our lawyers combine decades of practical experience with internationally recognised academic expertise to provide legal solutions that are both legally rigorous and commercially realistic. Every matter is approached individually, taking into account not only the criminal allegations but also the wider implications for the client’s personal life, professional career, business operations, regulatory obligations, and long-term objectives.

Recognised Expertise in Criminal Law

Our Criminal Law Practice is led by Professor Dr. Vahit Bıçak, one of Türkiye’s leading authorities on criminal law, criminal procedure, and the law of evidence. His academic publications, international teaching appointments, expert witness experience, and decades of courtroom practice provide our clients with a unique combination of scholarly insight and practical advocacy. This academic foundation enables our lawyers to analyse complex legal issues from multiple perspectives and develop innovative defence strategies based on current legislation, judicial practice, comparative law, and evolving international standards.

Nationwide Representation Across Türkiye

Although our offices are located in Ankara and İstanbul, our legal services are not limited by geography. We represent clients before judicial authorities throughout the entire jurisdiction of Türkiye. Whether a criminal investigation is conducted in İzmir, Antalya, Bursa, Gaziantep, Trabzon, Diyarbakır, Adana, Muğla, or any other province, our lawyers are able to coordinate legal representation efficiently while maintaining consistent communication and strategic oversight. Our nationwide practice enables us to assist clients in complex matters involving multiple prosecutors’ offices, several courts, or investigations extending across different regions of the country.

Trusted by International Clients

A significant proportion of our work involves advising foreign nationals, multinational corporations, international investors, diplomatic missions, overseas law firms, and international organisations on matters involving Turkish criminal law. We understand the additional challenges faced by international clients, including language barriers, unfamiliar legal procedures, cross-border evidence, international cooperation, immigration issues, and reputational concerns. Our lawyers regularly coordinate with foreign counsel, embassies, insurers, forensic specialists, and other professionals to ensure that our clients receive seamless legal support. Our ability to communicate effectively in cross-border matters allows us to bridge the gap between different legal systems while protecting our clients’ interests within the Turkish legal framework.

Strategic Defence Beyond the Courtroom

Effective criminal defence is not limited to courtroom advocacy. Decisions made during the earliest stages of an investigation frequently determine the direction and outcome of the entire case. For this reason, we place particular emphasis on:

• early case assessment;
• evidence preservation;
• legal risk analysis;
• witness preparation;
• procedural strategy;
• negotiations with prosecuting authorities where appropriate;
• coordination with technical experts;
• protection of commercial and reputational interests.

Whenever possible, we seek to resolve legal issues before they escalate into lengthy criminal proceedings.

Full-Service Legal Support

Criminal investigations often give rise to parallel legal issues extending beyond criminal law itself. Depending on the circumstances, clients may also face regulatory investigations, disciplinary proceedings, civil litigation, employment disputes, administrative sanctions, tax issues, asset recovery, compliance obligations, or international legal proceedings. As a full-service law firm, we are able to provide integrated legal support across these related practice areas. Our multidisciplinary approach ensures that criminal defence strategies are coordinated with broader legal and commercial considerations, reducing risk and delivering comprehensive legal solutions.

Integrity, Confidentiality, and Client Commitment

Every criminal matter requires the highest standards of confidentiality and professional responsibility. We recognise that criminal allegations can have profound consequences for individuals, businesses, and their families. Our lawyers are committed to providing discreet, responsive, and transparent legal representation. We keep our clients informed throughout every stage of the proceedings, explain available legal options in clear and practical terms, and work tirelessly to protect their rights while pursuing the most favourable outcome achievable under the law. Above all, we regard every client relationship as a partnership built on trust, professionalism, and unwavering commitment to excellence.

Our Criminal Defence Services

Every criminal matter presents unique legal, personal, and commercial challenges. At Bıçak Law Firm, we provide strategic legal representation tailored to the specific circumstances of each client and each case. From the earliest stages of a criminal investigation to trial, appeal, and post-conviction proceedings, our objective is to protect our clients’ rights while achieving the most effective legal outcome. Our lawyers advise and represent individuals, company directors, executives, professionals, public officials, entrepreneurs, multinational corporations, and international clients in virtually every aspect of Turkish criminal law.

Legal Assistance During Criminal Investigations

The investigation stage is often the most critical phase of any criminal matter. Decisions taken during the first hours or days following an allegation may significantly influence the future course of the proceedings. We provide immediate legal assistance in relation to:

• Police interviews and questioning
• Statements before the Public Prosecutor
• Criminal complaints
• Witness interviews
• Search and seizure procedures
• Digital evidence and forensic examinations
• Arrest and detention proceedings
• Judicial control measures
• Asset freezing and confiscation measures
• Applications for release

Our lawyers ensure that our clients’ procedural rights are fully respected while carefully monitoring every investigative measure carried out by the authorities.

Criminal Defence Before Turkish Courts

Where criminal charges are filed, we provide comprehensive legal representation before all levels of the Turkish criminal justice system. Our services include:

• Preparation of defence strategies
• Drafting legal submissions and petitions
• Court representation
• Examination of evidence
• Cross-examination of witnesses and experts where permitted
• Challenging unlawful evidence
• Legal arguments concerning criminal liability
• Sentencing submissions
• Appeals before higher courts

Throughout the proceedings, we maintain close communication with our clients and continuously review the evolving legal strategy in light of newly emerging evidence and judicial developments.

White-Collar Crime and Corporate Criminal Defence

Businesses and senior executives increasingly face criminal investigations involving complex commercial and financial matters. Our lawyers regularly advise companies and individuals in relation to allegations involving:

• Corporate fraud
• Financial crime
• Breach of trust
• Embezzlement
• Bribery and corruption
• Money laundering
• Tax-related offences
• Capital markets offences
• Banking and financial regulations
• Competition-related criminal investigations
• Cyber-enabled financial crime
• Corporate compliance failures

We understand that corporate investigations often involve parallel regulatory, civil, and reputational risks. Accordingly, our defence strategies are designed to address both the criminal proceedings and their wider commercial implications.

Internal Investigations and Compliance

Preventive legal advice is often the most effective form of criminal defence. We assist companies in conducting internal investigations into suspected misconduct while ensuring compliance with Turkish law and applicable international standards. Our services include:

• Internal investigations
• Employee misconduct investigations
• Corporate compliance reviews
• Anti-corruption programmes
• Anti-money laundering (AML) compliance
• Whistleblowing investigations
• Data preservation
• Risk assessments
• Regulatory reporting obligations

Where appropriate, we work alongside forensic accountants, cybersecurity specialists, auditors, and technical experts to provide multidisciplinary solutions.

Criminal Appeals

An unfavourable judgment does not necessarily represent the end of a criminal case. We advise clients regarding available appellate remedies and represent them before:

• Regional Courts of Appeal
• The Court of Cassation (Yargıtay)
• The Constitutional Court of Türkiye
• The European Court of Human Rights where applicable

Our lawyers carefully analyse trial records, identify procedural or substantive legal errors, and prepare comprehensive appellate submissions aimed at protecting our clients’ legal rights.

Representation of Victims of Crime

Our Criminal Law Practice is not limited to defending suspects or defendants. We also represent victims of crime by:

• Preparing criminal complaints
• Participating in investigations
• Representing victims during criminal trials
• Applying for protective measures
• Pursuing compensation claims
• Coordinating related civil litigation
• Protecting victims’ procedural rights throughout criminal proceedings

We understand that victims require not only legal representation but also practical guidance and effective advocacy throughout the criminal justice process.

Criminal Law Advisory Services

Not every criminal law matter results in prosecution. Many clients seek preventive legal advice before legal risks develop into criminal proceedings. Our advisory services include:

• Criminal risk assessments
• Legal opinions on Turkish criminal law
• Regulatory compliance advice
• Corporate criminal liability
• Due diligence reviews
• Criminal law implications of commercial transactions
• Cross-border criminal law advice
• Strategic legal consultations

Early legal advice frequently enables individuals and businesses to minimise criminal exposure and avoid future disputes.

Emergency Criminal Defence

Certain criminal situations require immediate legal intervention. Our lawyers provide urgent legal assistance in matters involving:

• Arrest
• Police custody
• Search warrants
• Emergency questioning
• Detention hearings
• Prosecutorial interviews
• Urgent applications before criminal courts

Rapid legal assistance during the earliest stages of proceedings is often essential to protecting fundamental rights and ensuring that procedural safeguards are respected.

A Comprehensive Criminal Law Practice

Our Criminal Law Practice extends far beyond courtroom advocacy. We provide strategic legal advice, proactive risk management, criminal defence, appellate representation, compliance support, and expert legal analysis across the full spectrum of Turkish criminal law. Whether representing an individual accused of a criminal offence, advising a multinational corporation during a regulatory investigation, assisting a foreign national facing criminal proceedings, or protecting the rights of a crime victim, our lawyers remain committed to delivering practical, discreet, and effective legal solutions tailored to each client’s circumstances.

Criminal Proceedings in Türkiye

Understanding how criminal proceedings operate in Türkiye enables individuals and businesses to make informed decisions when facing criminal allegations or investigations. Although every case has its own unique characteristics, criminal proceedings generally follow a structured legal process designed to ensure both the effective administration of justice and the protection of fundamental rights. At Bıçak, we guide our clients through every stage of this process, providing strategic legal advice, protecting procedural rights, and ensuring that each decision is made with a clear understanding of its legal and practical consequences.

Criminal Complaints and Reporting Criminal Offences

Criminal proceedings often begin when a complaint is submitted to the Public Prosecutor’s Office or law enforcement authorities. Certain offences require a formal complaint by the victim, while more serious offences are investigated ex officio by the prosecution authorities regardless of whether a complaint has been filed. Preparing an accurate and legally sound criminal complaint is frequently one of the most important steps in the entire process. A properly drafted complaint should clearly explain the factual background, identify available evidence, and present the legal basis supporting the allegations. Our lawyers assist clients in preparing criminal complaints, organising documentary and digital evidence, identifying witnesses, and ensuring that all relevant legal issues are properly presented from the outset.

Criminal Investigation

Once a criminal allegation has been reported, the Public Prosecutor directs the investigation to determine whether sufficient evidence exists to bring criminal charges. Depending upon the nature of the case, the investigation may involve:

• interviewing suspects, victims, and witnesses;
• obtaining expert opinions;
• examining financial records and digital evidence;
• conducting searches and seizures authorised by the courts;
• collecting forensic evidence;
• requesting information from public authorities and financial institutions;
• obtaining technical reports.

Throughout this stage, prosecutors are expected to investigate both incriminating and exculpatory evidence objectively. Individuals who become the subject of a criminal investigation are entitled to various procedural safeguards, including the right to legal representation.

Early legal advice during the investigation stage is often critical. Timely intervention may influence investigative decisions, preserve important evidence, protect procedural rights, and significantly affect the future course of the proceedings.

Arrest, Detention and Judicial Control Measures

In certain circumstances, Turkish law permits the temporary restriction of an individual’s liberty while criminal proceedings are ongoing. These measures may include police custody, judicial control obligations, or pre-trial detention where the statutory conditions are satisfied. Because these measures may have significant personal and professional consequences, courts are required to balance the needs of the investigation against the individual’s fundamental rights and freedoms. Our lawyers regularly represent clients during detention hearings, applications for release, judicial control proceedings, and related appellate procedures. We work to ensure that any restriction of liberty complies with Turkish law, constitutional guarantees, and applicable international human rights standards.

Criminal Prosecution and Trial

Where the Public Prosecutor concludes that sufficient evidence exists, an indictment is submitted to the competent Criminal Court. Once accepted by the court, the criminal prosecution formally begins. During the trial, the court examines the evidence presented by both the prosecution and the defence before determining whether the prosecution has established criminal liability beyond the applicable legal standard. Depending upon the nature of the allegations, criminal proceedings may involve:

• documentary evidence;
• witness testimony;
• expert reports;
• forensic examinations;
• financial analyses;
• digital evidence;
• technical investigations.

Our lawyers prepare comprehensive defence strategies, challenge unlawful or unreliable evidence where appropriate, examine expert reports, identify procedural irregularities, and advocate vigorously for our clients throughout the proceedings.

Appeals

Turkish criminal judgments may generally be reviewed through appellate procedures designed to ensure that both procedural and substantive law have been correctly applied. Appeal proceedings allow higher courts to review legal issues including:

• procedural irregularities;
• unlawful evidence;
• incorrect interpretation of legislation;
• errors in legal reasoning;
• sentencing issues;
• violations of constitutional or fundamental rights.

Where appropriate, our lawyers represent clients before the Regional Courts of Appeal, the Court of Cassation, the Constitutional Court of Türkiye, and, where domestic remedies have been exhausted, the European Court of Human Rights.

Protecting Our Clients Throughout Every Stage

Criminal proceedings rarely affect only one aspect of a client’s life or business. Allegations of criminal misconduct may influence employment, professional licences, immigration status, commercial relationships, regulatory obligations, contractual rights, and personal reputation. For this reason, our role extends beyond traditional courtroom representation. Throughout every stage of the proceedings, we work proactively to:

• protect procedural rights;
• preserve evidence;
• coordinate with technical experts where necessary;
• manage parallel administrative or civil proceedings;
• advise on regulatory implications;
• minimise commercial and reputational risks;
• pursue practical and strategic solutions that serve our clients’ long-term interests.

By combining legal knowledge with strategic judgement and commercial awareness, we seek not only to defend criminal allegations but also to protect the broader interests of every client we represent.

For this reason, our lawyers adopt a multidisciplinary approach to criminal matters, working closely with colleagues specialising in corporate law, compliance, employment law, international trade, arbitration, cybersecurity, data protection, and regulatory investigations whenever a client’s circumstances require broader legal support. Our objective is not merely to defend criminal allegations but to protect our clients’ businesses, reputations, assets, professional careers, and long-term interests through comprehensive legal representation.

Frequently Asked Questions

I have been contacted by the police or the Public Prosecutor. What should I do?

If you are contacted by the police or the Public Prosecutor regarding a criminal investigation, you should seek legal advice as early as possible. Early legal representation helps protect your procedural rights, ensures that statements are properly prepared, and may significantly influence the future course of the investigation.

Do I need a lawyer during a criminal investigation?

Although legal representation is not mandatory in every criminal matter, obtaining legal advice at the earliest stage is strongly recommended. A criminal investigation may have serious legal, financial, professional, and personal consequences. An experienced criminal defence lawyer can explain your rights, assess the evidence, prepare an appropriate legal strategy, and represent you throughout the proceedings.

Yes. Bıçak Law Firm provides criminal defence services throughout the entire jurisdiction of Türkiye.

Yes. Our Criminal Law Practice includes the representation of victims throughout criminal investigations, criminal proceedings, appeals, and compensation claims. We assist victims in protecting their procedural rights while pursuing justice and, where appropriate, financial compensation.

Do you prepare expert witness reports?

Yes. Our firm prepares independent expert witness reports and legal opinions on Turkish criminal law and criminal procedure for use before foreign courts, arbitral tribunals, insurance companies, international organisations, and overseas law firms.

Can companies be investigated under Turkish criminal law?

Yes. Although criminal liability primarily attaches to individuals under Turkish law, companies may be affected by criminal investigations through security measures, regulatory sanctions, confiscation proceedings, compliance obligations, internal investigations, and criminal allegations involving directors, officers, or employees. We advise both corporations and senior executives in managing these legal risks.

Do you assist with criminal appeals?

Yes. We represent clients before the Regional Courts of Appeal, the Court of Cassation, the Constitutional Court of Türkiye, and, where appropriate, the European Court of Human Rights. Every appeal is carefully prepared following a comprehensive review of the trial proceedings, applicable legislation, and relevant case law.
