In insurance terminology, what is another name for an endorsement?

An endorsement in insurance terminology refers to a document that modifies the terms of an existing insurance policy. This can be to add, remove, or change coverage, and it often serves to clarify the details of the policy. The term "attachment" is synonymous with endorsement because it indicates that this document is attached to the original policy, hence modifying it officially.

In insurance practice, it is not uncommon for policies to include endorsements that provide specific coverages, exclusions, or conditions that were not included in the original policy. Thus, referring to it as an "attachment" appropriately describes the function and purpose of an endorsement within the written insurance contract.

Other terms such as "certificate," "exclusion," and "definition" have distinct meanings and uses within insurance contexts and do not convey the same function as an endorsement, which is to alter or specify terms of coverage.
