Missing Contracts: On the Rationality of not Signing a Prenuptial Agreement

Abstract

Many couples do not sign prenuptial agreements, even though this often leads to costly and inefficient litigation in case of divorce. In this paper we show that strategic reasons may prevent agents from signing prenuptial agreements. Partners who value more the benefit of the marriage wish to signal their type by running the risk of a costly divorce. Hence this contract incompleteness arises as a screening device. Moreover, the threat of costly divorce is credible since the lack of an ex-ante agreement leads to a moral hazard problem within the couple, which induces partners to reject any ex-post amicable agreement.symmetric information, incomplete contracts, prenuptial agreement.
