Which of the following is NOT true about life insurance applications?

The statement that "statements made on the applications are warranties" is not true, which is why it is the correct answer. In the context of life insurance applications, the information provided by the applicant is typically referred to as representations, not warranties.

Repentations are statements that the applicant believes to be true to the best of their knowledge at the time of application. They are held to be accurate and can be relied upon by the insurer, but they do not carry the same absolute obligation as warranties, which are guarantees that certain statements are true.

On the other hand, the other statements are indeed true. The application must be signed by the applicant, ensuring that the applicant acknowledges the information provided. The application is usually incorporated into the insurance policy contract, meaning it is part of the official documentation governing the insurance agreement. Additionally, if there are misstatements made on the application, the insurer has the right to contest and potentially void the policy during the contestable period if those misstatements are material to the risk being insured.
