Duchy of Jülich
Reginald died childless near Arnhem on 25 June 1423 and was buried at Kloster Monkhuizen. The Duchy of Jülich descended to his first cousin once removed Adolf. The Duchy of Guelders descended to Reginald's grandnephew, Arnold of Egmond, although the House of Jülich fought unsuccessfully against the House of Egmond for this title.
