# 42 leading law firms in Grand Est

Tamtam tracks 42 law firms headquartered in Grand Est. This list ranks all of them by number of employees on LinkedIn, led by EY Société d'Avocats, ICC Arbitration and WeMa. Their median headcount is 23. Half of them were founded in 1989 or later. The most common headquarters are Strasbourg (11), Metz (3) and Schiltigheim (3).

The law firms in Grand Est are primarily large and mid-sized legal practices, alongside accounting firms and legal publishers. Cabinet d'avocat, with 7,263 employees, provides legal advice and representation. EY Société d'Avocats offers legal and tax advisory services, while ACD AVOCATS specializes in full-service legal support for companies. Editions Francis Lefebvre deciphers legislation and regulations, providing analytical legal content.

A notable pattern is the presence of several major legal publishers and accounting firms alongside traditional law practices. While many firms are headquartered in Grand Est cities like Strasbourg, Nancy, and Colmar, a significant number of the larger entities, such as ICC Arbitration and Simmons & Simmons France, are based in Paris, indicating a broader national reach for legal services in the region.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
