In the 2026 edition of Global Arbitration Review’s GAR 100, our arbitration team is once again the only Norwegian practice recognised. This recognition reflects our strength in complex cross-border disputes, where clients highlight our quality, strategic insight, and consistent performance.

Wikborg Rein is participating at the International Bar Association's annual conference in Toronto next week. Our partners Ketil E. Bøe, Kaare A. Shetelig, Marie Nesvik, Oddbjørn Slinning and Tormod Ludvik Nilsen are joining more than 5000 fellow lawyers from all over the world for a week of professional development and networking.

Immunity may shield a foreign state’s assets from enforcement in Norway, but not unconditionally. If the foreign state is engaged in commercial activities in Norway, it will be treated as its commercial peers, and immunity will not shield the assets involved in the commercial activity from attachment.

Global Arbitration Review has unveiled its annual ranking of the world’s leading international arbitration practices – and Wikborg Rein is proud to once again be listed among the selected firms in the GAR 100 for 2025, as the only Norwegian law firm included.
