First, we show that divorce is a risk because it is possible to estimate its probability of occurrence and the expected losses for each ex spouse. Then, the insurance offer is studied. In particular, we discuss the potential beneficiaries of this offer, the losses to compensate and the various types of insurance, especially relative to the classical problem of adverse selection and moral hazard. Finally, the demand of insurance is analysed and we focus not only on the problems of risk perception but also on the possibility for the spouses to limit the losses, by self-insurance and self-protection.
