The firm also assists in the process of negotiating settlements and taking actions before both national and international arbitration chambers. In order to provide the highest level of service for our clients, who frequently require fast and reliable coverage in other Brazilian states and worldwide, the firm has forged alliances with carefully selected partners to support their needs.

Our clients have regular contact with the professional in charge of the case and we always seek to put forward useful suggestions and constructive solutions.
