What modifies the original insurance contract by adding or removing coverage?

Endorsements are specific additions or modifications to an existing insurance policy that alter its terms. They can expand or limit coverage, clarify provisions, or modify exclusions based on the policyholder's needs or changes in circumstances. For instance, if a homeowner wants to add coverage for a newly purchased valuable item, an endorsement would be used to include that item in their existing policy.

In contrast, amendments, although similar in intent, typically refer to changes made to the terms or clauses of a legal document overall, rather than being specific modifications within an insurance policy. Exclusions are clauses that list what is not covered by the policy, effectively limiting coverage rather than modifying it in a manner that adds or broadens it. Addendums are supplementary documents that can provide additional information but do not serve the same direct purpose as endorsements in modifying existing coverage. Thus, endorsements distinctly serve the role of modifying the original insurance contract by adding or removing coverage, making them the correct choice.
