Investigations

When a compliance issue, regulatory enquiry or allegation of wrongdoing arises, the consequences can be significant, affecting operations, reputation and commercial objectives. CMS helps organisations navigate these challenges with confidence, providing strategic advice at every stage, from prevention and preparedness through to investigations, enforcement action and dispute resolution.

Our multidisciplinary investigations team combines specialists in financial crime, financial services enforcement, competition, data protection, employment, health and safety, environmental law, sanctions, life sciences regulatory matters and tax disputes. This breadth of expertise enables us to deliver practical, joined-up advice tailored to the issues facing your business.

We support clients in designing and strengthening compliance frameworks, embedding effective controls and fostering a culture of compliance. When issues arise, we conduct sensitive internal investigations, manage interactions with regulators and enforcement authorities, respond to dawn raids, and defend clients in criminal, regulatory, and civil proceedings.

Through CMS's global network, we can rapidly assemble cross-border teams to manage complex matters involving multiple jurisdictions, regulators and legal regimes, providing clients with seamless support wherever issues arise.

Clients trust CMS with their most sensitive and business-critical matters because we combine technical excellence, sector expertise and international reach with clear, commercial advice focused on protecting their business, people and reputation.
