About
Who we are
Founded in 1991, we have built our reputation as a prominent name in Brazilian commercial litigation, recognized for handling complex, high-stakes disputes for major Brazilian and international companies.
We combine the strength of more than three decades of experience with the agility of a firm that is constantly evolving, working with technical rigor, strategic vision and a close understanding of our clients’ businesses.
Pioneering spirit and impact: we are Leite, Tosto e Barros Advogados
We were born with the conviction that legal practice demands more than mastery of the law: it takes the courage to be a pioneer.
Founded in 1991, we have built more than three decades of history handling complex disputes, structured transactions and matters that shape Brazil’s business environment. Throughout this journey, we have advised Brazilian and international companies at the moments that most call for technical skill, strategy and trust — and we have built significant experience across sectors including finance, energy, infrastructure, agribusiness, aviation and ports.
Our practice integrates litigation and advisory work: we represent clients in highly complex court, arbitration and administrative proceedings, while also supporting them in structuring projects, preventing risks and making strategic decisions.
What has defined us all these years is the combination of technical rigor, business acumen and close relationships with our clients — an approach that turns legal knowledge into tangible support for those who make critical decisions.
Expertise
We operate at the forefront of the law, leading civil and banking litigation in Brazil while advancing strategic advisory practices in corporate and commercial law. Our work goes beyond traditional legal practice: we offer high-value solutions focused on dispute prevention and on structuring projects that give our clients’ businesses legal certainty.
Philosophy
We believe that legal excellence is built on close client relationships, commitment and a deep understanding of each client’s challenges. Our practice is guided by personalized attention, technical rigor and the pursuit of agile, efficient solutions. Combined with technology and innovation, this approach allows us to deliver speed without compromising technical rigor.
