The verdict in three sentences
Buyers of arbitration and corporate legal services in Luxembourg now ask AI assistants like ChatGPT before drawing up a shortlist: the general counsel of a German industrial group, the in-house lawyer of a Kirchberg management company, or an investment fund facing a dispute with a state. A firm appears in those answers when public information about it is consistent, factual and echoed by credible third parties, not because it bought visibility. The work is measured with a dated record of the answers to the same questions over time, costs a 2026 ballpark of 3,000 to 10,000 EUR for a diagnostic, and never guarantees a recommendation.
What clients now ask AI assistants
Clients choose an arbitration firm on partner reputation, experience of seats and institutions (ICC, LCIA, ICSID, the Asian centres), working languages and sector knowledge. Luxembourg adds its financial centre, holding and fund structures, and a multilingual environment. The questions put to AI assistants mirror those criteria:
| Question asked to an AI assistant | Who asks | What the assistant looks for |
|---|---|---|
| "Which Luxembourg firms have ICC arbitration experience in energy?" | General counsel of an industrial group | Sector expertise pages, partner profiles |
| "Luxembourg lawyer for a shareholder dispute in an alternative fund" | Management company | Fund litigation page, publications |
| "Luxembourg firm able to plead in German and English" | German or Swiss group | Working languages per partner, consistent everywhere |
| "Who advises on investment arbitration through a Luxembourg holding?" | International fund or investor | Investment arbitration page, signed articles |
| "Arbitration or the Luxembourg district court for a commercial contract?" | SME executive | Clear, dated explanatory content |
| "Arbitration firms in Luxembourg with a partner who sits as arbitrator" | Board of directors | Factual, verifiable biographies |
| "Enforcing an arbitral award in Luxembourg" | Foreign correspondent lawyer | Background note on exequatur, in general terms |
These questions do not ask for a ranking: they ask for facts. An assistant that cannot find those facts in consistent sources answers vaguely, cites better documented peers or, worse, attributes to your firm expertise it does not have.
Why some firms appear and others do not
No provider controls AI answers. Recurring factors do show up among firms that are described correctly:
| Factor | What helps | What hurts |
|---|---|---|
| Consistent information | Same name, partners and languages on the site, directories and profiles | Former partners still listed, outdated address |
| Third-party mentions | Legal directories, specialist press, conferences, institution publications | Nothing outside the firm's own site |
| Factual pages | One page per practice, with seats, institutions and sectors | A generic "Disputes" page |
| Structured data | Organisation, lawyers and addresses marked up cleanly | Nothing machine readable |
| Freshness | Dated articles, kept up to date | Last news item from 2021 |
| Languages | Aligned French, German and English versions | English version cut down to three pages |
Professional rules matter too. Lawyers' communication in Luxembourg is governed by the rules of their Bar: no promise of outcome, no identifiable client matter without consent, caution with rankings and comparisons. GDPR and the CNPD apply to forms and tracking tools. This is not legal advice: your Bar or ethics partner decides edge cases. Never invent a case, ranking or award: an assistant repeats what it finds, exaggerations included.
What the work covers and what it costs
In broad terms, AI visibility work for a law firm covers recording what answers say today, identifying the sources they use, aligning public information, factual pages per practice and per language, and regular follow-up. It is an emerging market and prices vary widely.
| Service | 2026 ballpark, Luxembourg and region | Note |
|---|---|---|
| One-off diagnostic | 3,000 to 10,000 EUR | Depends on questions, languages and practices |
| Monthly follow-up | 2,000 to 7,000 EUR a month | Often combined with existing SEO |
| Rewrite of expertise pages | 4,000 to 15,000 EUR | Legal copy approved by partners |
| Local legal communications agency | 150 to 250 EUR an hour | Strong on press relations, weaker on measurement |
| Quarterly record only | 800 to 2,500 EUR a quarter | For firms handling the rest in house |
These amounts reflect typical agency quotes and public rate pages, with no study behind them. At Kolonell this work is on quote. As a reference in professional services, we built the website of TR Signing Group, a signing services company in New Jersey.

The honest measure is a dated record: the same list of questions, in French, German and English, put to AI assistants like ChatGPT every month or quarter, with the answers archived. Three things are tracked: the share of answers that mention the firm, the accuracy of what is said (partners, languages, seats, practices), and the sources put forward. Over 12 months a trend emerges; over a single week it means nothing.
Mini case study
Illustrative example: Moselle Arbitration Partners, a fictional 14 lawyer firm in Kirchberg. A record of 25 questions in three languages shows the firm mentioned in 3 answers, and 2 of those 3 credit it with a partner who left in 2023. It invests 7,500 EUR in a diagnostic, then 3,000 EUR a month for 9 months, so 34,500 EUR in total. Nine months later it appears in 8 answers out of 25, 32 percent against 12 percent, and 7 of those 8 answers are accurate. Nothing is guaranteed, but general counsel who discover the firm this way now read correct facts.
FAQ
Can AI assistants like ChatGPT really influence the choice of an arbitration firm?
They are mainly used to build a first list of 3 to 5 names before the usual checks. The final choice still rests on partners, track record and referrals.
How much does a diagnostic cost for a Luxembourg firm?
A 2026 ballpark is 3,000 to 10,000 EUR depending on languages, practices and questions. A trilingual firm with four practices often sits towards the top of that range.
Can you guarantee our firm will be recommended?
No. Nobody controls these answers; the work makes public information consistent and checks, record after record, whether it is repeated correctly.
Should the whole site be translated into German and Luxembourgish?
Expertise pages and biographies in French, German and English cover most clients. Luxembourgish helps with local clients and is rarely decisive in international arbitration.
How long before a visible change?
Often 3 to 9 months, depending on how often sources refresh. A quarterly record over 12 months gives a reliable reading.
