An insurance investigator examines insurance claims that are suspicious or otherwise in doubt. Investigators in this field have differing specialties and backgrounds. Some insurance companies have their own in-house investigation teams while other companies sub-contract the work to private investigators or private investigation firms.[1] Although such investigations are usually conducted to combat fraud, very often investigators will be working simply to establish the circumstances of a particular claim (for example, in a multi-vehicular road accident involving various parties, claims and insurance companies).
