Which document typically governs the relationship and responsibilities between the insurer and insured?

The correct answer is the policy conditions because this document outlines the specific responsibilities, rights, and obligations of both the insurer and the insured. Policy conditions are crucial as they set the framework for the entire insurance contract, detailing what is expected from both parties and the process for filing claims, reporting losses, and the circumstances under which coverage may be denied or canceled.

While the policy declaration provides an overview such as the insured's information, coverage amounts, and premium details, it does not delve into the operational aspects of the insurance agreement. The insurance application is primarily focused on the information provided by the insured to the insurer to assess risk and does not govern the ongoing relationship. Endorsement clauses are used to modify the terms of the policy, but they are generally more specific in nature and do not encompass the overall duties and responsibilities of both parties as comprehensively as the policy conditions do.
