A fraud investigation service investigates potential instances of fraud, most typically as related to insurance or financial fraud. Fraud investigation services employ professionals with various roles, each with their own duties and responsibilities. For example, as a remote investigator, you work from home to collect evidence to determine whether or not the subject of the investigation committed fraud. Your duties include documenting your findings for potential civil or criminal litigation. Fraud investigation services sometimes employ remote customer service representatives whose responsibilities involve gathering information relevant to the fraud complaint from customers and updating them on the progress of their case.
