Learn how businesses can protect their commercial reputation in Turkey. Discover legal remedies against defamation, false business claims, misleading advertising, online reputation attacks, unfair competition, damages, injunctions, and criminal complaints in this 2026 Updated Legal Guide.

A company’s reputation is one of its most valuable commercial assets. Trust built over many years can be damaged within hours by false allegations, misleading advertisements, defamatory online publications, fake customer reviews, or malicious business statements. For foreign companies operating in Turkey, reputational attacks may result in lost customers, cancelled contracts, declining revenues, and long-term damage to brand value.

Commercial reputation disputes have become increasingly common due to digital marketing, social media platforms, online review websites, e-commerce marketplaces, and intense market competition. Competitors, former employees, disgruntled business partners, or anonymous online users may publish false statements that damage a company’s credibility.

Turkish law provides multiple legal remedies to protect commercial reputation. The principal legal framework includes the Turkish Commercial Code (TCC), which regulates unfair competition, the Turkish Code of Obligations (TCO) governing compensation claims, the Turkish Civil Code, the Industrial Property Code, the Law on the Regulation of Publications on the Internet (Law No. 5651) for online content, and the Turkish Criminal Code where defamatory or fraudulent conduct constitutes a criminal offense.

This 2026 Updated Legal Guide explains how foreign companies can protect their commercial reputation in Turkey, what legal remedies are available against defamatory business statements, and the practical steps businesses should take when facing reputational attacks.

Examples include:

• False corruption allegations.
• Claims of insolvency.

Misleading Comparative Advertising

Businesses may compare products or services only within the limits established by Turkish law.

Comparative advertising should:

Employment agreements should include:

Interim Injunctions

Where reputational damage is ongoing, businesses may seek urgent judicial measures to:

• Reduce ongoing harm.

Interim relief may be particularly important where false information is spreading online.

Removal of Online Content

Where unlawful content appears on websites or digital platforms, legal remedies may include applications for:

• Compliance with Law No. 5651.

Examples include:

• Fraudulent conduct.
• Computer-related offenses.
• Blackmail.
• Certain forms of defamation involving natural persons.
• Forgery.
• Unauthorized access to digital systems.

Whether criminal liability arises depends on the specific facts and the applicable provisions of the Turkish Criminal Code.

• Digital metadata.
• Customer complaints.
• Witness statements.
