No misrepresentation or false warranty made by the insured or in his behalf in the negotiation for a policy of insurance, or breach of a condition of such policy shall defeat or avoid the policy or prevent its attaching unless such misrepresentation, false warranty or condition shall have been stated in the policy or endorsement or rider attached thereto, or in the written application therefor. No such misrepresentation or false warranty shall defeat or avoid the policy unless it shall have been made with actual intent to deceive or materially affects either the acceptance of the risk or the hazard assumed by the company. With respect to a policy of insurance as defined in subsection (a), (b), or (c) of Section 143.13, except life, accident and health, fidelity and surety, and ocean marine policies, a policy or policy renewal shall not be rescinded after the policy has been in effect for one year or one policy term, whichever is less. This Section shall not apply to policies of marine or transportation insurance.
