Establishing And Maintaining A Business Presence In Türkiye 2026
This article examines the establishment and continuing management of a foreign business presence in Türkiye. It compares subsidiaries, branches and liaison offices, and considers capital, corporate documentation, governance, representative authority, investment reporting, work authorisation and data protection. Judicial decisions concerning corporate organisation and management duties are considered in their relevant context. The analysis argues that the choice of vehicle should follow the proposed activity, ownership arrangements and expected life of the investment. Effective legal preparation connects incorporation with the company's subsequent compliance, financing, decision-making and exit arrangements rather than treating registration as the final objective.
