Forensic Services are a decisive factor in advising clients in challenging situations, such as internal investigations requested by management or owners, regulatory inquiries and investigations conducted by law enforcement authorities, as well as in disputes and due diligence reviews.

During times of crisis, Forensic Services work with our lawyers across practices and regions to provide clients with a seamless service in fraud investigations, white collar crime cases and litigation.

The Forensic Services team also assist with employment related issues (including ethics), anti-competition, and breaches of confidential data, including GDPR. They support our contentious practitioners in obtaining and reviewing source documentation, using a dedicated IT platform for document analytics. With this in-house capability we are able to analyse business and financial data in fraud and compliance cases, identify misuses of data, and interpret financial, accounting, and commercial documents.

Forensic Services also provide transactional support on real estate and M&A deals, analysing potential risks of business activities, and checking capital interrelations.

Using forensic technologies in due diligence, fact-finding, and documents production we can support you with:

  • Internal and regulatory investigations
  • eDiscovery and Forensic Data Analytics
  • Background checks
  • Fraud prevention and post fraud support
  • M&A and disputes
