On June 13, 1246, Guillaume and his uncle Raymond I , Prince of Orange, made a partition, with Raymond receiving the lion's share of the possessions, and Guillaume got only the large tower of Orange Castle and the lord of Courtezon. In 1247, Guillaume and Raymond were captured by the rebel inhabitants of Orange . July 1, 1248 he made a will, according to which all his possessions (including in Sardinia), if his marriage remained childless, were to go to Uncle Raymond I, with the exception of Curtezon, who was bequeathed to his brother Raymond II. In 1256, Guillaume III and his wife brought homage to Karl of Anjou for their possessions in the Gap diocese.
