is a measure of material interest in insurance. It is expressed in insurance amount and insurance policy terms and conditions. None of individuals or legal entities may fall back on insurance if it does not have an insurance interest in insurance facility or does not expect it to occur. It is understood that an insured must suffer material damage if insured property is lost or damaged or if an insured has a material interest to the third parties in connection with insured property. Implied interest means that an insurer must not necessarily have an insurable interest in insured property at the time of conclusion of insurance agreement.
