A more thorough explanation:

An entire-agreement clause, also known as an integration clause, is a provision in a contract that states that the entire agreement between the parties is contained within the contract. This clause is often included in insurance contracts and can include the application, declarations, insuring agreement, exclusions, conditions, and endorsements.

John signs a contract with a car insurance company. The contract includes an entire-agreement clause that states that the contract contains the entire agreement between John and the insurance company. This means that any previous discussions or negotiations between John and the insurance company are not part of the contract.

Another example is a real estate purchase agreement. The entire-agreement clause in the agreement states that the written contract contains the entire agreement between the buyer and seller, and any previous discussions or negotiations are not part of the agreement.

These examples illustrate how an entire-agreement clause limits the scope of the contract to only what is included in the written agreement. This helps to prevent any misunderstandings or disputes that may arise from previous discussions or negotiations that were not included in the contract.
