The firm is one of the best prepared law firms in Brazil in these areas, providing clients with all-inclusive services, from legal advice on marketing, promotions advertisement, labelling and commercial policy, to full class action litigation. The firm offers full assistance on recall cases, handling the administrative work before regulatory and consumer agencies, investigations before the Public Attorney’s Office and individual consumer litigation (e.g. product liability).


In addition, the firm has extensive experience with food law, unfair competition, commercial disputes and corporate controversies (contractual or equity related). The firm also advises several businesses and industry associations on issues related to consumer safety and standards regulation, especially regarding labelling, children’s advertising and food safety.
