The short paper publishes and issues a previously unknown charter of Catherine of Žerotice, written in Czech language in 1447. Up to now it lay hidden from the eyes of scholars in archives of princely Hohenlohe-Zentralarchiv Neuenstein (Baden-Württemberg). The charter concerns the selling of maternal heritage both in Bohemia and in Moravia at Catherine's sister Anna. Because of greater legal force six nobles from the surrounding area were asked to seal the charter with their seals.
