Turkey has been tried to adopt its legal system to the European legal system for 25 years. The last 3 examples of it are; the new Code of Obligations, Commercial Code and the Code of Civil Procedure. Turkey has been recently an interesting and attractive country for especially foreign investors and it is seen that the aim of the recent legal regulations are to increase and intensify the mentioned interest and attractiveness and as well as simplify the foreign investment. Consequences of this policy has been realized in a short time, in other words more foreign companies has been started to prepare to invest in our country. Our Office has provided services for Turkish and foreign investors especially in the field of energy and defense both in Turkish, German and English, since it was founded. As consequences of the political developments between Turkey and European countries and USA the economic relations will be developed as well and more foreign companies will invest in Turkey.
