The legal framework for accessory guarantees (cautionnements) and autonomous guarantees (garanties autonomes) was a source of legal uncertainty given that, based on how the guarantee was written, an accessory guarantee could be requalified as an autonomous guarantee and more frequently, an autonomous guarantee could be re-qualified as an accessory guarantee. On 1 July 2020, the Luxembourg legislator adopted a new law on professional payment guarantees (the “Law”) in order to provide the parties with greater contractual flexibility and solve re-qualification issues.
