Under European law, there are no general rules whit respect to the liability of a holding company for the debts of its insolvent subsidiary.

The Council Regulation (EC) N° 1346/2000 of 29 May 2000 on insolvency proceedings only provides for a common framework for insolvency proceedings in the European Union (EU). The harmonised rules on insolvency proceedings intend to prevent assets or judicial proceedings being transferred from one EU country to another for the purposes of obtaining a more favourable legal position to the detriment of creditors (“forum shopping”).

Through its decision of 27 November 2008, the Belgian Constitutional Court declared netting arrangements in insolvency proceedings, which are explicitly allowed under the Belgian Financial Collateral Law of 15 December 2004, unconstitutional where such netting arrangements apply to non-merchants. Despite the numerous criticisms about this decision, the amended Belgian Financial Collateral Law, entered into force on 10 November 2011, now explicitly excludes non-merchants from its scope.
