What is a certificate that adds to or changes the coverage of an insurance policy?

The correct choice is endorsement, as it refers to a document that alters the terms or coverage of an existing insurance policy. An endorsement can add new coverage, modify existing coverage, or exclude certain threats to improve the policyholder’s protection according to their needs. This flexibility allows policyholders to tailor their insurance coverage to better reflect their specific risks and circumstances.

In the context of insurance, a rider typically means something slightly different. While it can also modify coverage, it often refers to an additional provision or policy that is attached to an existing policy, which can be used interchangeably with endorsement in some cases but generally has more specific applications. Conditions refer to obligations or requirements that must be met for the insurance policy to be valid and effective. Exclusions are specific situations or items that are not covered by the insurance policy. Understanding the definitions and differences among these terms is crucial for effective management of insurance policies.
