Third-party insurance is an insurance policy purchased for protection against the claims of another. One of the most common types is third-party insurance is automobile insurance. Third-party offers coverage against claims of damages and losses incurred by a driver who is not the insured, the principal, and is therefore not covered under the insurance policy. The driver who caused damages is the third party.
Making a claim with “the other driver’s” insurance company? That’s a third-party claim. Driving a company car and sustain an injury? You’re making a third-party claim there, too. Injured while driving your own car in the course of your job? A third-party claim with your employer’s insurance company would be your mechanism for recovery of medical and repair costs. Any claim made to an insurance company other than your own is considered a third-party claim.
