Criminal Law Risks in Commercial Transactions in Türkiye: What Business Owners and Foreign Investors Should Know

Introduction

Commercial disputes are generally perceived as matters of civil or commercial law. However, certain actions undertaken in the course of business activities may also trigger criminal liability under Turkish law. In practice, company directors, shareholders, managers, authorized signatories, and other individuals exercising effective control over a business may face personal criminal responsibility for unlawful conduct carried out on behalf of a company.

During a recent legal webinar organized by Beta Law Office, Attorney Osman Aydın discussed the principal criminal law risks arising in commercial transactions and highlighted several issues that frequently affect both Turkish businesses and foreign investors operating in Türkiye.

Personal Criminal Liability in Corporate Activities

A fundamental principle of Turkish criminal law is the personal nature of criminal liability. Although legal entities cannot generally be subjected to criminal punishment, individuals acting on behalf of a company may be held personally liable for criminal offenses committed within the scope of corporate activities.

This means that directors, managers, board members, authorized representatives, and even individuals who effectively control company decisions may face criminal prosecution where their actions contribute to unlawful conduct.

The argument that a person merely acted on behalf of a company does not eliminate criminal responsibility. Turkish law also recognizes the principle that ignorance of the law is not a valid defense.

In addition to criminal penalties imposed on individuals, courts may apply security measures against legal entities, including:

Revocation of operating licenses;
Confiscation of assets obtained through criminal conduct;
Other preventive measures provided under the Turkish Criminal Code.
Qualified Fraud in Commercial Transactions
One of the most significant criminal risks for businesses is qualified fraud.

Under Article 158 of the Turkish Criminal Code, fraud may arise when deceptive conduct is used to obtain financial benefit at the expense of another person. Commercial transactions carried out through fraudulent representations may constitute aggravated forms of fraud, resulting in substantial criminal penalties.

A common example involves real estate development projects. Criminal liability may arise where a developer knowingly sells apartments or commercial units despite being aware from the outset that construction is legally or practically impossible.

Turkish courts carefully distinguish between genuine commercial failure and fraudulent intent. Where a company has genuinely commenced construction, invested resources, and later becomes unable to complete the project due to financial difficulties, the matter will generally be treated as a civil dispute rather than a criminal offense.

However, where evidence demonstrates that the promised project could never have been completed and that the seller was aware of this fact from the beginning, criminal prosecution for qualified fraud may follow.

Tax Crimes and False Accounting Records

Tax-related offenses represent one of the most common sources of criminal liability for business owners and company managers.

Under Article 359 of the Tax Procedure Law, criminal liability may arise from:

• Issuing false invoices;
• Using false invoices;
• Destroying accounting books or records;
• Manipulating financial documentation;
• Maintaining inaccurate accounting records.

Criminal responsibility generally extends to company executives, accounting managers, and individuals who make or approve financial decisions.

Foreign investors should be particularly cautious when accepting invoices and supporting documentation from third parties. Turkish authorities increasingly scrutinize accounting records, and businesses are expected to exercise reasonable diligence when verifying the authenticity of tax documents.

Forgery of Official and Private Documents
Document integrity plays a critical role in commercial life.

Turkish criminal law distinguishes between:

• Forgery of official documents;
• Forgery of private documents.

Criminal liability may arise through:

• Creating false documents;
• Altering genuine documents;
• Using forged documents in commercial transactions.

Examples frequently encountered in practice include falsified invoices, contracts, delivery notes, corporate resolutions, and other business records.

Because commercial transactions rely heavily on documentary evidence, courts view document forgery as a serious offense capable of undermining trust in commercial relations.

Breach of Trust and Misuse of Corporate Assets
Another important criminal offense affecting businesses is breach of trust.

This offense occurs when assets entrusted to an individual for a specific purpose are used contrary to that purpose.

In a corporate environment, breach of trust may arise where:

• A manager uses company funds for personal expenses;
• Corporate assets are diverted for unauthorized purposes;

Company property is used beyond the scope of granted authority.
The determining factor is not the individual’s corporate title but rather the existence of authority, intent, and actual involvement in the unlawful conduct.

Commercial Disputes vs. Criminal Offenses
One of the recurring questions raised by foreign investors concerns the distinction between commercial disputes and criminal conduct.

Many foreign clients expect criminal sanctions to be available whenever a supplier, developer, or business partner fails to perform contractual obligations. Turkish law adopts a more restrictive approach.

As a general rule, failure to fulfill a contractual obligation does not automatically create criminal liability.

For example:

• Failure to deliver goods after receiving payment;
• Inability to complete construction projects;
• Failure to satisfy financial obligations;

will often be treated as civil disputes unless clear evidence demonstrates fraudulent intent from the outset.

This distinction is particularly important for foreign businesses accustomed to legal systems where criminal enforcement mechanisms are more readily available in commercial disputes.

Due Diligence for Foreign Investors
Foreign investors conducting business in Türkiye should implement comprehensive compliance procedures to minimize criminal law risks.

Recommended measures include:

• Verifying the legal and financial standing of counterparties before entering transactions;
• Conducting thorough due diligence on construction and investment projects;
• Maintaining complete and accurate accounting records;
• Carefully reviewing invoices and supporting documents;
• Cooperating fully with tax inspectors and regulatory authorities;
• Establishing internal compliance and reporting mechanisms;
• Seeking legal advice before executing high-value transactions.

Conclusion

Commercial activity in Türkiye may give rise not only to civil liability but also to significant criminal law consequences. Directors, managers, shareholders, and authorized representatives should understand that criminal responsibility may arise from their personal actions, decisions, or omissions, even when acting on behalf of a company.

For foreign investors, understanding the distinction between commercial disputes and criminal offenses is particularly important. Effective compliance programs, proper documentation, and proactive legal guidance remain the most effective tools for reducing criminal law exposure and safeguarding business operations in Türkiye.
