Tamtam tracks 140 law firms headquartered in Brazil. This list ranks the 50 largest by number of employees on LinkedIn, led by Escritório de Advocacia, Escritório Particular de Advocacia and Defensoria Pública do Estado de São Paulo. Their median headcount is 1,073. Half of them were founded in 1987 or later. The most common headquarters are São Paulo (16), Rio de Janeiro (6) and Florianópolis (3).

This selection of large legal services providers in Brazil includes a mix of private law firms and public legal institutions. Among the private firms, Escritório de Advocacia (Belém) and Nelson Wilians Advogados (São Paulo) specialize in advocacy and legal representation.

Softplan, a software development company, is also present, focusing on management software for public and private businesses.

The list highlights a concentration of these large legal entities in major Brazilian cities. São Paulo is a prominent hub, hosting several large private law firms such as TozziniFreire Advogados, Mattos Filho, and Machado Meyer Advogados, all offering comprehensive business law services. Rio de Janeiro also features with public institutions like Defensoria Pública do Estado do Rio de Janeiro - DPGE and Procuradoria Geral do Estado do Rio de Janeiro.

## 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.
