The most recommended law firms
On 5 November 2026 we asked Claude, with web search, 15 questions a business in Copenhagen might type when looking for a law firm, and asked each question twice. These are the firms it recommended most often across the 30 answers.
| Law firm | Recommended in (of 30) | Named first |
|---|---|---|
| Kromann Reumert | 23 | 11 |
| Gorrissen Federspiel | 22 | 5 |
| Plesner | 22 | 0 |
| Bech-Bruun | 21 | 0 |
| Mazanti-Andersen | 17 | 6 |
| DLA Piper | 17 | 1 |
| HortenDahl | 16 | 0 |
| Accura | 16 | 0 |
| Lund Elmer Sandager | 13 | 1 |
| Bruun & Hjejle | 8 | 0 |
| Skau Reipurth | 8 | 1 |
“Named first” counts the answers where the firm was the first one mentioned.
The big four almost always come up
Kromann Reumert, Gorrissen Federspiel, Plesner and Bech-Bruun appeared together in 20 of the 30 answers, and at least one of them in 23. The seven answers without any of them were all to questions that asked for something else: smaller firms, personal service, alternatives to the big firms, or a firm for a business in growth.
Size in the question changes the first name
When the question mentioned a company of 50 to 200 or 80 employees, a mid-sized business, a growing one or alternatives to the big firms, Claude often started with Mazanti-Andersen instead. It was named first in six answers, all to questions of that kind, often followed by Lund Elmer Sandager and HortenDahl before the largest firms. Questions about smaller firms and personal service produced a long tail of names that hardly appeared anywhere else. In total the answers named 51 firms.
Answers are stable at the top
Asking the same 15 questions a second time gave very similar results for the largest firms: Kromann Reumert was recommended in 11 answers in the first round and 12 in the second, and Gorrissen Federspiel and Plesner in 11 both times. The smaller names changed more from round to round.
Legal rankings were the main source
Claude cited the legal directories Legal 500 or Chambers in 28 of the 30 answers, often to explain which practice areas a firm is ranked in. Review sites mattered much less than for online shops: Trustpilot appeared in only 7 answers.
What it means for a law firm
Thirty answers can’t tell you why one firm is picked over another. They do show what the assistant leaned on: directory rankings and the firms’ own descriptions of who they serve. If you run a law firm, make sure your site says plainly which clients and matters you handle, in text and in schema.org data, keep your directory listings current, and consider an llms.txt file. To see where you stand today, measure your AI visibility on the questions your clients ask.
Method
- Date: 5 November 2026.
- Assistant: Claude with web search. Each answer came from a fresh session that knew nothing about this study or the other answers.
- Rounds: each question was asked twice, 30 answers in total, all of which came back.
- Counting: a firm counts once per answer it is recommended in, however often it is mentioned there. Spellings of the same firm were merged, and Horten and DAHL, which have merged into HortenDahl, count as one firm.
- Limits: answers vary from day to day, and other assistants such as ChatGPT and Gemini may recommend other firms. The numbers describe these 30 answers, not the market.
