Forensic Auditing

Hahn & Hahn Services

Although our service offering is titled forensic auditing the fact of the matter is that a forensic investigation by its very nature does not constitute an audit and therefore the correct terminology is in fact a forensic investigation or then the practice of forensic accounting.

Our forensic department is headed by one of our partners, Jaco Hamman who holds a Masters degree in Forensic Accounting as well as a LLB degree. Prior to joining Hahn & Hahn attorneys Jaco formed part of PricewaterhouseCoopers’ forensic division which is currently the biggest Auditing firm in the world.
