What document defines the agreement between an individual and an insurer regarding insurance arrangements?

The correct answer is the policy, which is a formal document that outlines the agreement between an individual (the policyholder) and the insurer regarding the terms and conditions of the insurance coverage. The policy details the coverage limits, premiums, deductibles, exclusions, and the responsibilities of both parties involved. It serves as the primary legal contract that governs the insurance relationship, ensuring that both the insurer and the insured understand their rights and obligations.

While the term "contract" is broadly applicable to any legal agreement, in the context of insurance, the document that specifically outlines the terms of the insurance coverage is referred to as a policy. Endorsements are modifications or additions to a policy that can change coverage details or conditions, and declarations are part of the policy that summarize key information but do not, by themselves, constitute the full agreement between the parties.
