Firm overview

ASC Law proudly combines one of the most experienced and successful senior leadership teams in Turkey with the next generation superstars. Each of our three Founding Partners – Murat Aksu, Zeki Calişkan and Okan Beygo – have been practicing law over 30 years.

Recognizing, early on, the need for a local firm able to satisfy the growing demands of globalization, our founders’ vision was to bring together, under one roof, lawyers providing legal services meeting, and exceeding, international standards. This goal was quickly achieved, and we now have what we believe is the most sophisticated practices in Turkey.
