Financial Crime & Investigations

Increasingly aggressive regulatory supervision and scrutiny in the financial sector demand equally determined and focused legal representation.

White-collar crime

In recent years, white-collar crime (ranging from bribery and money laundering offences to securities violations and fraud) has been drawing more attention.

Prosecutors and regulators are targeting businesses, companies and individuals around the world as never before. Countries actively pursue the regulation of financial activities beyond their borders, leading to increased cooperation between law enforcement and regulatory bodies around the world.

We assist clients in the development and implementation of compliance programmes, codes of conduct, codes of ethics and whistle-blowing programmes. We assist clients in the turmoil of investigations led by public prosecutors, and we lead internal investigations requested by our clients.

We dare to care about our clients’ reputational risk. We help them navigate through their crisis. In litigation cases that are subject to media scrutiny, we also assist our clients in their communication strategy, and we stand by them in press conferences whenever required.

Grégoire Mangeat, partner, and Fanny Margairaz, partner, are recommended lawyers by The Legal 500 and ranked by Chambers Europe in the White-Collar Crime category for Switzerland.
