N.J. Stat. Ann. § 17:37-5

Any mutual fire insurance company of this state, at the time of issuing a policy of insurance, may, with the assent of the insured, make the whole or any part of the loss which may occur under the policy payable to any person, other than the insured, who may have an interest in the property, and make indorsement thereof on the policy. Where the assent of the insured to the appropriation of the money to be paid in satisfaction of any loss that may occur under the policy is indorsed on the application for insurance or survey of the property insured, it shall constitute a part of the application or survey, and be sufficient authority to the company for the issuance of the policy in the manner therein prescribed.
