According to a royal charter from 1271, the monastery had 10 monks and one abbot in that year.Salomon, "Histoire de l’abbaye des Écharlis", 22-23 In 1336, the papal bull Summi magistri dignatis issued by Pope Benedict XII required that Cistercian monasteries numbering more than 40 monks send at least one of them to receive theological training.Dom Romain Clair, "Hautecombe" (Aix-les-Bains: Société d’art et d’histoire d'Aix-les-Bains, 2010). The monastery of Les Écharlis was well below this number, which also explains the lack of daughter houses.Régnier, "Histoire de l’abbaye des Écharlis", 244
