What type of information must a liability insurer disclose upon written request?

In the context of liability insurance and responding to written requests, the correct answer is that a liability insurer must disclose full policy information. This requirement aligns with the principle of transparency and the right for policyholders or interested parties to understand their coverage.

Full policy information includes critical aspects such as the terms and conditions of the policy, endorsements, exclusions, and definitions relevant to the coverage. By disclosing this comprehensive information, insurers help policyholders grasp the extent of their protection and any limitations that may exist.

While claims history, personal details, and coverage limits are important components related to insurance policies, they do not encompass the entire breadth of information that might be necessary for a complete understanding of the policy in question. For instance, coverage limits may inform one aspect of the liability coverage but do not provide the entire context needed for an understanding of the complete policy. This comprehensive approach ensures that policyholders are fully informed about their rights and obligations under the policy they hold.
