Insurance fraud expert witnesses may testify on insurance claims, insurance regulations, and associated matters. On their website, the Coalition Against Insurance Fraud writes:
What is Fraud?
Insurance fraud occurs when people deceive an insurance company or agent to collect money to which they aren’t entitled. Similarly, insurers and agents also can defraud consumers, or even each other. Insurance fraud can be “hard” or “soft.”
Hard Fraud. Someone deliberately fakes an accident, injury, theft, arson or other loss to collect money illegally from insurance companies. Crooks often act alone, but increasingly, organized crime rings stage large schemes that steal millions of dollars.
Soft Fraud. Normally honest people often tell “little white lies” to their insurance company. Many people think it’s just harmless fudging. But soft fraud is a crime, and raises everyone’s insurance costs. Consider…
A car owner inflates a fender bender claim to cover her deductible, or she understates how many miles she drives annually to lower her auto premium… A homeowner inflates the value of his stereo equipment stolen during a robbery… Or a printing business lists fewer employees than it really has in order to pay lower workers compensation premiums.
