Our Services

Contracts

Contract Law

Counsel across every stage of a contract, from drafting to dispute resolution. Before signing, our work is preventive and strategic: clarifying risk, aligning expectations and drafting precise instruments.

Business

Corporate and Employment Law

A strategic legal arm for day-to-day operations and employment relations. Preventive compliance and risk management; in litigation, debt collection and defence in labour claims.

Corporate

Corporate Transactions

Restructurings, mergers and acquisitions (M&A), judicial reorganisation and bankruptcy, incorporations and dissolutions. Rigorous review of legal, tax and regulatory risk, aligned with the company’s goals.

Family

Family and Succession Law

Preventive counsel and representation in court and out of it, handled with care: estate planning, probate, division of assets, divorce, civil partnership, maintenance, custody and paternity.

International

International Relations

Services for foreign individuals and companies, and for Brazilians with ties abroad, focused on Brazil–France. Deal structuring, document regularisation, cross-border contracts and immigration.

Environment

Environmental and Urban Planning Law

Permitting, regularisation of construction and liability for environmental damage. We reconcile development, housing and sustainability through an ESG lens, with proactive solutions rather than reactive defence alone.

Legislative

Legislative and Constitutional Law

Working at the meeting point between making law and defending it. Legislative counsel to lawmakers and public managers, and constitutional litigation through public civil actions and citizen suits.

Human Rights

Human Rights

Civil enforcement of human rights, with emphasis on the protection of minorities. For the LGBTI+ community, claims to secure rights and to obtain damages, affirming identity and full citizenship.

Health

Health Law

Representing individuals, families and small businesses against health plan providers: wrongful denial of coverage, abusive premium increases and sham group plans, handled with an eye to urgency.

Administrative

Administrative Law

Administrative law counsel ensuring compliance with the applicable rules. Public procurement and contracts, misconduct defence, and probity claims in environmental matters.

Civil servants

Public Service Careers

Counsel to civil servants throughout their career: lawfulness of public examinations, promotions, transfers, grading and career entitlements, before the administration and in court.

What guides us

Our Values

Three pillars that carry every case — and that name the way we practise law.

Social

Social

The head thinks where the feet stand: law does not hover above life. It operates inside relationships, companies, families and the very making of who we are. We take structural inequality into account and commit to defending voices that history has pushed to the margins.

Intellectual

Intellectual

There is no practice without theory. We cultivate constant academic development and a practice in conversation with many fields of knowledge — because “whoever knows only law does not even know law”. To be intellectual is to join precision to sensitivity.

Creative

Creative

For us creativity is not ornament: it is a premise. We look for the fertile detour, the opening through which a legal innovation can be applied. Our arguments — technically rigorous and elegantly made — are not afraid of the unexpected, because to create is to communicate better.

Culture

Art is law as well.

Fiction and imagination are as essential to human survival as the truth. Art is not merely entertainment: it is what lets us build the world — and what founds us as subjects, including subjects of law.
