Firm overview

Since 1989, Hergüner Bilgen Üçer Attorney Partnership has been recrafting the Turkish law firm model along modern corporate standards, while maintaining the personal attention that its clients have come to expect. Its size and expertise make it one of the few truly full-service independent Turkish law firms with a global reach, equally at home in the role of primary counsel in multinational transactions and local counsel to foreign and domestic clients. The firm’s expertise and institutional knowledge enable it to go beyond simple lawyering and develop creative business-oriented solutions to client needs. It accomplishes this by putting clients first and becoming intimately acquainted with all aspects of their business and legal needs. The firm’s reputation for innovation goes back over three decades, having drafted many first-of-their-kind agreements in cross-border transactions that continue to be used as model agreements in the market today.
