Learn how unfair competition is regulated under Turkish Commercial Law. Discover legal remedies for foreign companies, misleading advertising, trade secret theft, employee solicitation, trademark misuse, injunctions, damages, and court proceedings in this 2026 Updated Legal Guide.

Turkey is one of the largest commercial markets in the region and attracts thousands of foreign investors each year. International companies establish subsidiaries, distributors, manufacturing facilities, retail chains, franchise networks, technology businesses, logistics operations, and joint ventures throughout the country. While Turkey offers significant commercial opportunities, businesses may also face unfair competitive practices that threaten market position, reputation, customer relationships, and profitability.

Competitors may engage in misleading advertising, unauthorized use of confidential information, imitation of products or services, unlawful solicitation of employees, false commercial statements, trademark misuse, or unfair pricing strategies. Such conduct may distort competition and cause substantial financial losses.

The primary legal framework governing unfair competition is contained in the Turkish Commercial Code (TCC). The TCC prohibits commercial practices that violate the principle of good faith and adversely affect competitors, customers, or market participants. Depending on the circumstances, businesses may also rely on the Turkish Code of Obligations, Industrial Property Code, Personal Data Protection Law (KVKK), consumer legislation, and criminal law where applicable.

This 2026 Updated Legal Guide explains how unfair competition is regulated in Turkey, the legal remedies available to foreign companies, and the practical steps businesses should take to protect their commercial interests.
