The course aims at learning three of the alternative insolvency procedures to the Bankruptcy and to the withholding agreement, ie the procedures for over-indebtedness, compulsory administrative liquidation and extraordinary administration (of large companies in crisis). Students are given the opportunity to know bankruptcy proceedings with a specific regulation both for large companies, whose crisis is extremely detrimental to the economic fabric, both for the overindebtedness of the consumer or in any case of a non-fallible subject. Given the imminent entry into force of the so-called Rordorf reform of the crisis procedures, the main lines of this reform will also be illustrated.
