Which document is not used by insurance companies to make changes in the insurance contract?

The document that is not used by insurance companies to make changes in the insurance contract is the telephone change log. This type of log is often a record-keeping tool used to document changes discussed over the phone or actions taken, but it does not constitute a formal amendment or change to the insurance policy itself.

On the other hand, riders, endorsements, and floaters are specific documents that directly modify or enhance an insurance contract. A rider typically adds specific coverage or modifies existing terms and is attached to the original policy. An endorsement is a formal change or addition to the policy that alters the coverage, premium, or conditions of the contract. A floater is a specific kind of endorsement that provides coverage for movable or valuable items, indicating that each of these documents serves a legal and binding role in altering the terms of the insurance agreement.

Therefore, the telephone change log lacks the formal status and functionality of the other documents, making it clear why it does not qualify as a means for making changes to an insurance contract.
