An adjuster is a professional who evaluates insurance claims to determine the extent of the insurance company's liability. They assess damages, gather evidence, and negotiate settlements between the policyholder and the insurance company. Adjusters can work for insurance companies, independent firms, or as public adjusters representing the policyholder's interests. There are different types of adjusters, including property adjusters, who focus on damage to homes and businesses, and auto adjusters, who handle vehicle-related claims. Their role is crucial in ensuring fair compensation for losses while adhering to the terms of the insurance policy.
