Résumé : On the 13 April 862, King Lothar II granted a charter to the monks of Stavelot to confirm their estates (DD LII 17). A second charter, bearing the same date, provides details regarding the composition of those estates (DD LII †37). This document has been identified as a forgery, created between 873 and 902. This article focuses on the reasons that led to the falsification and proposes a new datation of the document. The charter was probably written during the turbulent times between Lothar the Second's death (August 869) and 873, climaxing around the Treaty of Meerssen (8th of August 870). The purpose of this forgery would have been to propose a detailed version of LII 17, to avoid dispersion and loss of monastic possessions due to the king's need to redistribute land to fideles.
