Since the Law of 10 July 2020 introduced the professional payment guarantee, there is a new mechanism in Luxembourg’s legal arsenal allowing redress of the loophole in positive law with respect to independent guarantees (garanties autonomes).

With the increasing importance of guarantees in financial transactions and the increasing risks, it is henceforth necessary to understand the differences between sureties (cautionnements), independent first demand guarantees (garanties autonomes à première demande) and professional payment guarantees (garanties professionnelles de paiement).

During this presentation, you will receive an overview of the different guarantees under Luxembourg law as well as their main characteristics and applications.

The programme:

  • Distinctions between sureties, first demand guarantees and professional payment guarantees; and
  • The new uses in practice of these different types of guarantees.


  • Learn the differences between sureties and independent guarantees;
  • Understand the innovations of the Luxembourg professional payment guarantee introduced by the Law of 10 July 2020;
  • Discover the main characteristics and possible uses of professional payment guarantees;
  • Identify the conditions for the application of the Law of 10 July 2020 on professional payment guarantees;
  • Safeguard contracts and their guarantees to avoid requalification; and
  • Benefit from the experience of DSM Avocat à la Cour’s attorneys since the entry into force of that law.
