With a global reach spreading across North America, the UK and internationally, MGI Worldwide’s Global Forensic Accountancy Group is here to assist with a choice of experienced accountancy expert witnesses situated across the globe.

Established to offer an affordable alternative to the Big 4 or larger accounting firms, MGI Worldwide’s lead Forensic Expert in the UK, Roger Issacs, at UK-based member firm Milstead Langdon explains:

“By instructing one expert in the jurisdiction where the litigation is taking place, who can rely on other accountants in other parts of the world to provide local accountancy expertise we can mesh together something where you don’t need experts in every jurisdiction, but the one lead expert relies, where appropriate, on colleagues in other countries to pull together something that is affordable and proportionate in terms of its cost.” 

Our specialist service areas relating to Forensic Accounting include:

  • Cross border divorcesLitigation support services for matrimonial lawyers acting for clients whose financial affairs span several jurisdictions
  • International FraudExpert witnesses experienced in bribery, embezzlement, money laundering, theft, trans-national accounting malpractice and international insurance claims 
  • International ArbitrationAssessment of profit loss, quantification of economical damage and commercial valuations 

Document discovery

MGI Worldwide’s lead Forensic Expert in the US, Kim Onisko, at US-based member firm O&S CPAs and Business Advisors further explains how working within a global accountancy network brings huge benefits when it comes to document discovery: 

Our association with MGI Worldwide and the Forensic Accountancy experts that are provided, allow us the ability to provide experts in document discovery in a number of different countries. That can be a key to a successful resolution.

Undisclosed bank accounts

Roger Isaacs also explained the value of being able to identify hidden, or undisclosed bank accounts: 

We now have access to an entirely legitimate organisation that can tell you with 99% certainty whether a particular individual with a particular email address has a bank account anywhere in the world. That has proven invaluable for asset tracing and to prove that certain parties to litigation are not being honest with their disclosure."
