Turkey: Contracts and Commercial Law

The Turkish Ministry of Trade has opened for public consultation a draft law on the protection of trade secrets that aims to establish comprehensive regulations aligned with European Union standards. The draft addresses definitions, protection mechanisms, unlawful acquisition, use and disclosure of trade secrets, while providing a complete framework covering exceptions, interim measures, confidentiality during proceedings, sanctions, jurisdiction and statute of limitations.

Turkey's Competition Authority had an intense April 2026, with major developments spanning payment systems, pharmaceutical sectors, and digital markets.

Turkish Commercial Code Article 21/2 establishes that merchants who fail to object to invoice contents within eight days are deemed to have accepted them. However, this article examines whether maturity dates and maturity differences added to invoices without prior agreement between parties can become binding solely through this presumption, or whether such terms require separate contractual foundation or established commercial custom.
