Firm overview

BBA // Fjeldco stands out among Iceland's largest corporate law firms, distinguished by our unique combination of local market leadership and international capabilities. With over 30 lawyers qualified across multiple jurisdictions, including Iceland, England, France, and several US states, the firm is notably the only Icelandic law firm with operational offices outside the country - in London, UK, and Lille, France.

Our international expertise is further enhanced by our team's unique composition. Several of our Icelandic lawyers have significant experience working abroad (over 40 years combined), while our English and French lawyers have worked extensively with Icelandic clients and in the Icelandic market for over a decade. This distinctive blend of international experience and deep local market knowledge, combined with our unique international footprint, ideally positions us for complex cross-border work.

The firm has established itself as a market leader in several core practice areas. In mergers & acquisitions, BBA//Fjeldco has played a pivotal role in Iceland's largest deals (including advising on the acquisition of Iceland’s first unicorn), consistently earning top rankings from major ranking firms. The banking and finance practice is particularly noted for handling complex, multi-jurisdictional financing structures, making it a trusted advisor to both local and international banks for their most sophisticated transactions. In capital markets, the firm has built a strong reputation through its work on public listings and capital-raising strategies, while its financial services and fintech practice provides crucial regulatory expertise and licensing support.

Our specialists have provided seminars and preparation for CEOs and board members of commercial banks, credit institutions, securities companies, other financial institutions, insurance companies, payment services companies and other regulated entities in relation to FSA’s qualification assessment process for such positions.

What truly sets BBA//Fjeldco apart is its position as the go-to firm for international companies and law firms seeking Icelandic legal expertise. It maintains strong relationships with global law firms such as Linklaters, A&O Shearman, and Clifford Chance, while its deep connections to the Icelandic business community, including representation on Chamber of Commerce boards, ensure it stays at the forefront of local market developments. This combination of international reach and local market leadership makes BBA//Fjeldco uniquely positioned in the Icelandic legal market.
