Controversies in the life insurance interests always exist between the doctrine of interests upheld by the Common Law system and the doctrine of consent by the Civil Law system. The Insurance Acts in Taiwan and Mainland China inherited the above system and therefore created conflicts in many aspects. Secondly, employment and labor relations can be treated as life insurable interests in Mainland China. The interest of a group member, the interested party of insurance contract de facto, might be jeopardized. Furthermore, in Mainland China, moral hazard might increase due to ”consent proves interest”, ”no written consent required” and ”no rights of revocation”. It is suggested that Mainland China shall, by reference to Taiwan's act, amend the requirement of written consent from an insured, and provide an insured the right of revocation to mitigate moral hazard.
