The firm: Réttur traces its origins back to 1969 when Ragnar Aðalsteinsson, one of Iceland’s leading attorneys, started his private practice in Reykjavík. Today, Ragnar’s partners at Réttur include Kári Hólmar Ragnarsson, Sigríður Rut Júlíusdóttir and Sigurður Örn Hilmarsson.

Renowned for its high level of professionalism, ethical standards and efficiency, the firm takes pleasure in giving its clients straightforward legal advice in a timely manner.

Areas of practice: The firm focuses on dispute resolution and has litigated many of the biggest cases in Iceland over the past years and decades, before both Icelandic and international courts.

Following the collapse of the Icelandic banks in October 2008, Réttur has acted for a large number of international companies, banks and investment firms, such as Deutsche Bank, BP, Bayerische Landesbank, Landesbank Baden Württemberg, BNP Paribas and Commerzbank, as well as a large group of international bondholders, co-ordinated by Akin Gump Strauss Hauer & Feld LLP, both in high-stake litigation and advising on insolvency, restructuring and other areas of law.

The attorneys at Réttur have extensive experience providing legal advice on the restructuring of debt, managing bankrupt estates, litigating rescission cases, and other aspects relating to the insolvency of companies, as well as natural persons. Furthermore, the firm’s attorneys have extensive experience advising in relation to the international winding-up proceedings of financial institutions.

Réttur provides legal services in commercial and corporate law, such as the formation and dissolution of legal entities, drafting of contracts, finance, international trade, dispute resolution and debt collections. The projects that Réttur has worked on include the re-financing of Hafnarfjörður Municipality and Reykjavik Energy (Orkuveita Reykjavíkur), and new investments in Icelandic Water Holdings.

Réttur has provided advice on capital controls and currency issues since the implementation of capital controls in Iceland in late 2008. The firm’s attorneys have assisted a vast number of foreign creditors in relation to their investment in Iceland, as well as providing assistance to investors in relation to investments and overseas loans.

The attorneys at Réttur have extensive expertise in the area of intellectual property and trade marks, having successfully worked in those fields for decades. They specialise in the protection of all intellectual property rights such as literature, visual artwork, inventions, scientific research, trade marks and patents. Supreme Court attorney Sigríður Rut Júlíusdóttir, a partner at the firm, is an appointed expert on the Icelandic Copyrights Committee and has extensive experience in the negotiation and litigation of intellectual property rights cases. Réttur has provided advice to the National Theatre of Iceland, the Living Art museum, the Writers Union of Iceland and numerous artists.
