Established in 1999, the firm Nelson Wiliams & Advogados Associados, which takes the name of its founder and President, works as the largest firm in Brazil, in terms of number of attorneys and offices owned.

Since 1999, NWADV has as one of its biggest achievements, the recognition of being a firm that works in every field of corporate law, with one of the broadest client lists in the country, ranging from national to international companies in various industries.

NWADV currently has the largest legal network of Brazil, owning 35 offices spread across every capital of the country and in the most important cities of every state, granting to our clients a unique standard of quality. Moreover, we made our operations international through strategic partnerships in France, Chile and Colombia, counseling companies of these countries that operate or aim to operate in Brazil and Brazilian companies that aim to do businesses abroad.

Moreover, NWADV has employed strategic policies for internal development, seeking new markets and clients, on top of strategies that have already been established in the legal market. The union of these two factors has allowed the firm to develop new practices and expand its structure, number of collaborates and clients counsels in the department of litigation and consultancy, getting a sustainable competitive advantage. We have one of the best process management systems ever tested and approved by our clients. Our compliance policy aims to follow the legal guidelines, with the goal of avoiding, detecting and dealing with any detour or unconformity that may occur.

Our structure is ready to offer to services of differentiated quality, in large scale litigation or in strategic or consultancy demands.
