An insurance adjuster, also known as a claims adjuster, is a professional who evaluates and investigates insurance claims. They play a very important role in the insurance industry, determining the appropriate compensation for the policyholder or any applicable third party.

Their task involves gathering relevant information, such as policy details, accident reports, and evidence, to determine the validity of the claim and its coverage. Additionally, they assess the extent of damage or loss by conducting site visits, inspecting property damage, or interviewing the parties involved.

There are different types of insurance adjusters, including public adjusters, independent insurance adjusters, and insurance investigators. 

Public adjusters are hired by policyholders to represent their interests and negotiate with insurance companies for fair settlements. 

On the other hand, independent insurance adjusters work on a contractual basis for insurance companies and handle claims on their behalf. 

Finally, insurance investigators specialize in investigating suspicious or fraudulent claims to protect insurance companies from potential losses.
