# Top 30 Law Practice companies in the Nord department
Tamtam tracks 54 Law Practice companies headquartered in the Nord department. This list ranks the 30 largest by number of employees on LinkedIn, led by HEPTA Cabinet d'Avocats en Droit des Affaires, SOLUCIAL Avocats and VIVALDI Avocats. Their median headcount is 10. Half of them were founded in 2014 or later. The most common headquarters are Lille (17), La Madeleine (4) and Roubaix (2).
These law practices in the Nord department primarily serve businesses, offering a range of specialized legal services. Firms like HEPTA Cabinet d'Avocats en Droit des Affaires provide legal advice and representation to businesses, while SOLUCIAL Avocats specializes in employment advice and litigation services for HR and management teams. VIVALDI Avocats focuses on Business Law, and THERET & ASSOCIES offers expertise in corporate, tax, patrimonial, and insurance law.
A notable pattern among these firms is their concentration in the city of Lille, with a significant number having their headquarters there. Many of these law practices are mid-sized firms, with employee counts ranging from around 10 to nearly 30, reflecting established operations rather than very large corporations or very young startups.

## 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 11, 2026.
