Who we are

We are a law firm dedicated to complex socio-environmental litigation and strategic disputes: civil and environmental liability, redress for collective harm, and matters of high technical complexity.

A deliberately small practice. We work on few subjects, in depth, under our own engagement terms and with our own team and infrastructure. Our lawyers and consultants have built their careers around disaster events and their effects on people, communities and territories.

In this field, experience cannot be improvised. Establishing what was lost, by whom and to what extent requires method, and method takes years to build.

What we do

Disaster law

Civil and environmental liability, individual and collective redress regimes, and the interface between administrative, judicial and negotiated processes.

Harm assessment and quantification

Methodologies for identifying, categorising and measuring material, moral, social and environmental harm: damage matrices, eligibility criteria and valuation parameters.

Technical reports and legal opinions

Studies, technical notes and opinions to inform legal, commercial and institutional decisions, including for use before foreign courts and tribunals.

Technical consultancy in complex litigation

Support to law firms, companies and institutions conducting large-scale disputes: analysis of legal theories, strategic input and technical support on evidence.

Redress programmes and settlement design

Design and review of compensation systems and collective settlements: governance, eligibility, evidentiary workflows and payment criteria.

Prevention, compliance and risk management

Assessment of exposure to socio-environmental and disaster risk, due diligence, alignment of internal policies and structuring of crisis response.

Training and capacity building

Training for legal and technical teams in disaster law, harm quantification and mass litigation, delivered as closed or bespoke programmes.

Our people

The firm brings together lawyers and consultants whose training and experience were built around disaster events, mass litigation and harm assessment. The profiles are complementary, spanning academic research, contentious practice, technical analysis and methodology design, which allows a single problem to be addressed from each of the angles it demands.

The firm is led by Karina Denari Gomes de Mattos, holder of a master's degree and a doctorate in law, who has worked in disaster law since 2019, when she joined the Rio Doce Project at Fundação Getulio Vargas and contributed to the main outputs of its socio-economic assessment, including the damage matrix. She supervises Field Projects on the Disaster Law course at FGV Direito Rio, researches with the disaster studies group at FGV Direito SP and within an international research project with the University of Bergen. She was the first lecturer on the Disaster Law programme of the Brazilian Bar Association's national law school (ESA/OAB) and is a guest lecturer at USP-Ribeirão Preto, PUC-RS and the Public Prosecution Service Law School of Goiás.
