Forensic accounting is the specialty practice area of accounting that describes engagements which result from actual or anticipated disputes or litigation. 'Forensic' means suitable for use in Court, and it is to that standard and potential outcome that forensic accountants generally have to work. Forensic accountants often have to give expert evidence at the eventual trial. All of the larger accounting firms, as well as many medium-sized and boutique firms have specialist forensic accounting departments. Within these groups, there may be further sub-specialisations: some forensic accountants may for example just specialise in insurance claims, personal injury claims, fraud, construction, or royalty audits.
