The UK Supreme Court’s recent decision in El-Husseini and another v Invest Bank PSC [2025] UKSC 4 has clarified the circumstances in which section 423 of the Insolvency Act 1986 (the Act) provides protection against attempts by debtors to “defeat their creditors and make themselves judgment-proof.” This is a critical decision for insolvency practitioners, any corporate or fund which is involved in distressed deals and beyond to acquirers who were not aware they were dealing in distressed assets.
