Final answer:
The provision of a life insurance policy that states the application is part of the contract is called the entire contract clause.
Step-by-step explanation:
In life insurance policies, the "entire contract clause" combines the application, endorsements, and attachments as necessary parts of the overall contract between the policyholder and the insurance provider. This clause attests to the agreement of the parties to the parameters of the application. It includes all pertinent documents and guarantees that they are included in the contract as a whole. The clause highlights the binding nature of the information provided during the application process by treating the application and its accompanying materials as part of the agreement. This protects the interests and commitments of the policyholder and the insurer within a comprehensive contractual framework.
