In insurance, the insurance policy is a contract (generally a standard form contract) between the insurer and the insured, known as the policyholder, which determines the claims which the insurer is legally required to pay. In exchange for an initial payment, known as the premium, the insurer promises to pay for loss caused by perils covered under the policy language.
Insurance contracts are designed to meet specific needs and thus have many features not found in many other types of contracts. Since insurance policies are standard forms, they feature boilerplate language which is similar across a wide variety of different types of insurance policies.
The insurance policy is generally an integrated contract, meaning that it includes all forms associated with the agreement between the insured and insurer. In some cases, however, supplementary writings such as letters sent after the final agreement can make the insurance policy a non-integrated contract.
