Criminal Compliance

Preventive legal services
There is no need to wait for a formal subpoena or indictment to protect yourself. Every company is subject to risks, which intensify in times of crisis. Non-payment of taxes, embezzlement of goods, and misdemeanors by employees are examples of situations that may imply criminal charges. To avoid the consequences of breaking the law, your company needs to anticipate preventive actions. Prevention can be done through integrity programs and audits, and we help you with this task. Criminal compliance involves the identification of threats, the development of the solution and its implementation.


To protect also means to investigate. Whether to prevent crimes, clarify facts or follow up on ongoing criminal investigations.

Internal investigations
For companies that are victims of crimes. We offer advice on internal investigations for preventing crimes, detecting illegal activities and to uncover evidence.

Defensive criminal investigation
We prepare your defense preventively, before any subpoena is issued. We investigate what happened, clarify facts and protect

We also assume, from other firms, the defense in appellate courts.
