AbstractThe main legal acts on International Insolvency Law (the European Regulation, the UNCITRAL Model Act and the European Convention on Certain International Aspects of Bankruptcy) lay down several local proceedings with substantive effects as regards the debtor, the distribution of proceeds and the ranking of claims. These—full—proceedings are characterized by a high degree of unpredictability and prove to be inadequate for creditors. These are the reasons why, as an immediate solution, the existing insolvency rules should be reinterpreted according to a certain logic of the market. However, such revision would only partially and provisionally solve the inconveniences of the current model. The true and ‘unsolvable’ problem is that even though the full local proceeding is based on international assistance, it alters the substantive insolvency rules. Therefore, in future it would be necessary to create a truly ancillary proceeding. Such a proceeding would not have any substantive effect as regards the debtor, the creditors and third parties, nor would it require any kind of distribution of proceeds and ranking of claims. However, this proceeding would enable to provide procedural assistance to foreign courts and procedural protection to local creditors. Copyright © 2010 John Wiley & Sons, Ltd.
