Oregon Revised Statutes Insurance § 742.016

(1) Except as provided in ORS 742.043, every contract of insurance shall be construed according to the terms and conditions of the policy. When the contract is made pursuant to a written application therefor, if the insurer delivers a copy of such application with the policy to the insured, thereupon such application shall become a part of the insurance policy. Any application that is not so delivered to the insured shall not be a part of the insurance policy and the insurer shall be precluded from introducing such application as evidence in any action based upon or involving the policy. Any oral representations by the insured that are not included in an application shall not be a part of the insurance policy and the insurer shall be precluded from introducing such representations as evidence in any action based upon or involving the policy.

(2) If any life or health insurance policy is reinstated or renewed, and the insured or assignee or beneficiary with a vested interest under such policy shall make written request to the insurer for a copy of the application, if any, for such reinstatement or renewal, the insurer shall, within 30 days after the receipt at its home or branch office of such request and of satisfactory evidence of such requesting beneficiary's vested interest, deliver or mail to the person making such request a copy of such application. If such copy shall not be so delivered or mailed, the insurer shall be precluded from introducing such application as evidence in any action based upon or involving such policy or its reinstatement or renewal.

(3) This section does not apply to surety insurance.
