Practice areas
Where would you like to start?
Who we advise
Companies and business owners
For partners, directors and managers who need to protect the company and its assets and to limit their own personal exposure.

Individuals
For you
For individuals facing an investigation, a lawsuit or a dispute with a bank or a supplier, who need confidential, technically rigorous advice.
Integrated approach
One set of facts rarely stays in one area.
An audit of a federal program can lead to an administrative claim, a special accounts proceeding (tomada de contas especial) before the Federal Court of Accounts (Tribunal de Contas da União, TCU) and a criminal investigation. A contract that is poorly performed can lead to a collection suit, proceedings to pierce the corporate veil (desconsideração da personalidade jurídica) and a criminal complaint against the partners.
When each front is handled by a different lawyer with no common strategy, one defense can undermine another. We analyze the matter across every area involved from the outset and pursue a unified strategy across all legal fronts.
Regulated companies and government contractors
Audits, administrative penalties, Court of Accounts proceedings and potential criminal exposure.
Partners and managers
Personal liability for company debts and conduct, asset freezes and investigations.
Companies in contract disputes
Breach, termination, collection and enforcement, with attention to the risks to partners.
