Wisconsin Statutes Insurance (Ch. 600 to 655) § 631.07. Insurable interest and consent

(1) Insurable interest. No insurer may knowingly issue a policy to a person without an insurable interest in the subject of the insurance.

(2) Consent in life and disability insurance. Except under sub. (3), no insurer may knowingly issue an individual life or disability insurance policy to a person other than the one whose life or health is at risk unless the latter has given written consent to the issuance of the policy. Consent may be expressed by knowingly signing the application for the insurance with knowledge of the nature of the document, or in any other reasonable way.

(4) Effect of lack of insurable interest or consent. No insurance policy is invalid merely because the policyholder lacks insurable interest or because consent has not been given, but a court with appropriate jurisdiction may order the proceeds to be paid to someone other than the person to whom the policy is designated to be payable, who is equitably entitled thereto, or may create a constructive trust in the proceeds or a part thereof, subject to terms and conditions of the policy other than those relating to insurable interest or consent.
