Methodology
How was the top-30 law-firm ranking built?
The ranking is a static snapshot dated August 29, 2026. It combines the DM Faster company registry, official PRH identifiers, the Finnish Bar Association's law-firm naming rule, and company-level public financial observations.
1. Defining law firms
The candidate population contains 169 active Finnish entities whose name, main industry, or reviewed activity indicated a law firm.
2. PRH identity verification
Every published row was matched to a current official name and Business ID in PRH Open Data. Foreign branches, ended entities, and duplicate identifiers were removed.
3. Financial observation
Each entity received its latest trusted public legal-entity revenue observation from Finder or Asiakastieto. Fiscal year, personnel, and source remain visible row by row.
4. Quality control and ranking
Patent agents, generic legal services, and broad tax or transaction advisers were separated from law firms. The remaining entities were sorted by revenue and the largest 30 were published.
Limitations you should read
- This is a reviewed market slice from DM Faster company data, not an official Finnish Bar Association or Statistics Finland market census.
- The ranking covers Finnish legal entities. International group revenue and foreign parent-company figures are excluded.
- Patent and trademark agencies, generic legal-service providers, and broad tax or transaction-advisory firms are excluded unless the legal entity is specifically a law firm.
- Separate legal entities belonging to the same brand or group may appear as separate rows. Roschier Asianajotoimisto Oy and Roschier Brands Asianajotoimisto Oy are therefore ranked separately.
- The latest comparable revenue observations cover fiscal years 2024 and 2025. The year is shown row by row and the figures should not be interpreted as same-year market shares.
- Two entities have no available personnel observation in the source used. The employee total covers 28 entities and does not represent global network headcount.
- Revenue measures legal-entity size, not legal quality, profitability, client satisfaction, or suitability for a particular matter.
- Public financial data changes. Rankings can move after a new filing, merger, demerger, or source correction.
