Dewey Ballantine and Czech firm Kotrlik Bourgeault Andrusko have ended their formal association less than a year after the New York firm’s local arm broke off to form the Prague practice.

The two firms’ co-operation agreement, signed after Dewey’s eight-lawyer Prague office left its parent firm in January, ended on 30 September, leaving Kotrlik Bourgeault to relaunch this month as a fully-independent practice.
