Firm Overview

Martorelli Advogados is a full-service law firm with significant expertise in Business/Corporate, Tax, Labour, Administrative, Civil, Consumer, Real Estate, Family, Environmental, and Regulatory Law.

With over 40 years of excellence, we have developed our own methodology and know-how to deliver agile, creative, and efficient legal solutions. What truly sets us apart is our deep commitment to understanding each client’s business. This allows us to act as genuine partners in their operations, addressing challenges in a tailored and assertive manner.

We are the result of a shared vision of legal practice: a team of professionals with broad proficiency across different areas of law and market sectors, united by the ability to understand new contexts and evolving demands. Together, we design strategic and creative legal solutions to meet the challenges of contemporary law, always focused on enhancing results.

We value diversity: 71% of our staff are women, 35% are mixed-race, and 10% are Black, reflecting our commitment to inclusion and representation.

We were the first law firm in Brazil to harness Google's Artificial Intelligence. Our AI serves as a technological compass, guiding us towards the best solutions for the growth of our clients' businesses. We are also agents of change, as we have assembled a part of our team and formed a multidisciplinary unit to provide exclusive services to startups. What's more, we have gone beyond that and created Project Shortcut, which has the clear objective of putting the Northeast on the world investment map in a direct manner.

Main Areas of Practice

Corporate

In Corporate, we cover contracts, mergers and acquisitions, real estate, estate and succession planning, corporate reorganisation, investment structuring (domestic or foreign), public-private partnerships, project finance, intellectual property, LGPD (general law on data protection) and digital law matters related to enterprises and entities, acting in both contentious and non-contentious matters.

To meet these demands, we develop and work with our own know-how, proposing creative and efficient legal solutions to ensure the effective realisation of business, whether structured via private equity, funding in general, M&A, or public-private partnerships.

Dispute Resolution

Our team has a remarkable track record when providing legal counsel in lawsuits resulting in the highest compensation payments in the country. Additionally, our practice excels in managing significant liabilities with financial institutions and engaging in administrative litigation with regulatory agencies such as the Central Bank of Brazil, CVM, ANS, and ANTAQ, among others.

What sets our team apart is our commitment to offering a personalised approach to each case. We assign highly specialised professionals dedicated to delivering comprehensive services to our clients. Our client base includes some of the largest Brazilian corporations, multinational companies, and businesses spanning key economic sectors in the country.

We operate across three major segments:

a) Judicial Litigation: This encompasses the full spectrum of activities related to the representation and management of highly complex civil cases, particularly those of substantial value or significant societal impact.

b) Administrative Litigation: We have a strong presence in handling cases before regulatory agencies, ensuring our clients' interests are well-protected and advocated.

c) Arbitration: Our expertise extends to all matters involving contract disputes submitted to arbitration, which allows us to provide effective solutions through this alternative dispute resolution mechanism.

Tax

Martorelli Advogados has a well-established Tax practice, with strong capabilities in both advisory and litigation matters. The team is particularly recognised for its performance in administrative and judicial tax disputes, especially in Brazil’s Northeastern region, including high-stakes matters related to federal taxes and State VAT (ICMS).

The firm is frequently instructed by clients in the infrastructure, agribusiness, and energy sectors—especially in the photovoltaic solar segment—seeking strategic and technically sophisticated tax solutions. More recently, the team has expanded its presence in the hospitality sector.

Martorelli is also known for combining legal expertise with a strong business-oriented approach, assisting clients in improving tax efficiency, mitigating risks, and reducing tax liabilities through innovative and compliant strategies.

Labour

Our specialised team operates in both collective and individual Labour Law matters, combining experience, technology, and industry-specific expertise to deliver outstanding results for our clients in judicial proceedings and public civil investigations.

We take a meticulous approach, acting before Attorney General’s Offices and Regional Labour Courts across the country, with close attention to each case and every stage of its progress.

We understand the strategic importance of case management for businesses. Our legal control department is structured into specialised units for each phase of the case lifecycle—registration, progress monitoring, reporting, payments, and closure—offering periodic management reports and conducting audits to ensure precision and efficiency.

In addition to our litigation work, we offer preventive advisory services aimed at avoiding risks, liabilities, and contingencies. Our proprietary technology, powered by artificial intelligence, helps identify the root causes of our clients’ challenges, enabling us to deliver assertive, innovative, and data-driven solutions to support informed decision-making.
