A binder or contract for temporary property lines of insurance may be made orally or in writing and is deemed to include all the terms of a standard fire insurance policy and all applicable endorsements as may be designated in the binder. However, the cancellation clause of the standard fire insurance policy and the clause specifying the hour of the day at which the insurance commences may be superseded by the express terms of the binder. A duly authorized binder must be accepted as evidence of insurance coverage required as a condition of financing the purchase of property, except that a mortgagee or lender is not required to accept a renewal or extension of the binder. Any insurance producer who has express authority to bind property and casualty lines of insurance coverage, and who orally agrees on behalf of an insurer to provide insurance coverage, if requested, shall execute and deliver a written memorandum or binder containing the terms of the oral agreement to the insured within three business days from the time of the oral agreement.
