Forensic accountants are experienced auditors, accountants, and investigators of legal and financial documents that are hired to look into possible suspicions of fraudulent activity within a company; or are hired by a company who may just want to prevent fraudulent activities from occurring. They also provide services in areas such as accounting, antitrust, damages, analysis, valuation, and general consulting. Forensic accountants have also been used in divorces, bankruptcy, insurance claims, personal injury claims, fraudulent claims, construction, royalty audits, and tracking terrorism by investigating financial records. Many forensic accountants work closely with law enforcement personnel and lawyers during investigations and often appear as expert witnesses during trials.
