Norwegian businesses rank Thommessen as the number one law firm in the Prospera Law Firm Review


With a record score, Thommessen is awarded the top rank in this year’s Prospera survey.

- Thommessen has in five of the last six years been ranked number one in the Prospera survey. This is a reflection of our unique team spirit, and I am incredibly proud that we are being ranked the top commercial law firm year after year, says Managing Partner Sverre Tyrhaug.

The Prospera Tier 1 Law Firm Review for Norway is an annual independent survey conducted by Kantar SIFO. The survey provides thoroughly researched feedback on how the 313 largest business clients rate Norwegian commercial law firms. All businesses interviewed have a minimum annual legal service procurement spending of NOK 1.5 million. In the 2020 survey, Thommessen shares the top spot with Wikborg Rein, but Thommessen is ranked ahead of all other firms by the largest clients, in addition to yet again being rated the firm with the strongest legal expertise.

Record score

This year, Thommessen is awarded the number one rank and the highest total score ever from the very largest clients – those with more than NOK 7 million in annual legal service procurement spending.

- We take the high praise from the largest legal service users as a strong endorsement of our approach, says Tyrhaug.

Thommessen is rated the number one firm in terms of commercial law expertise

The Prospera survey has two main sections. The first section ranks law firms on miscellaneous parameters, such as project management, strategic speaking partner, digitalisation, etc. The second section is focused on legal expertise – across a number of disciplines. Thommessen is also ranked number one in this latter section, being awarded the top score on legal expertise.

- Professional excellence is the key priority for clients. We are therefore extremely pleased that clients rank our lawyers as the industry leaders in terms of legal expertise. This year’s survey reaffirms our position as the firm with the strongest commercial law expertise, says Tyrhaug.
