Unlike individuals and corporations, countries indebted beyond their ability to pay cannot use bankruptcy laws to restructure unsustainable debt. The United Nations and the International Monetary Fund have attempted to propose treaties to enable that debt restructuring, but the political difficulties of reaching a worldwide consensus have stymied their efforts. This article argues that a model-law approach to restructuring unsustainable sovereign debt should be feasible and effective because the vast majority of sovereign debt contracts are governed by the laws of either the debtor-state or two other jurisdictions. Those jurisdictions individually could enact a model law to give struggling nations a real prospect of equitably restructuring their debt to sustainable levels. By enabling such debt restructuring, that enactment would also help to foster the norms required to facilitate the development of international treaties.
