As Chair of Lexlink Nils has visited the offices of the prospective new members of Lexlink across the world to meet the partners in these firms and verify their suitability for membership.
He has throughout his chairmanship focused both on recruitment and, in the interests of the clients of Lexlink members, on the importance he attaches to members attending the annual conferences in order to develop a close relationship with those to whom clients may in the future be referred.
Since his retirement from practice, Nils and his wife, Ulla, are based partly in Norway, where they enjoy having become grandparents, but also in both Denmark and Spain.
