The Zoudenbalchs had been staunch supporters of Gijsbrecht van Brederode and continued to remain close to him after his deposition. Gijsbrecht was given various highly profitable and prestigious clerical titles and prebends to compensate for the loss of his bishopric, including the right to retain his prestigious office of Provost of the Dom of Utrecht. As Provost he appointed his friend and ally against Burgundy, the Dom Canon Evert Soudenbalch, to act as his Socius and Officius. Furthermore, in 1470 Evert also succeeded Gijsbrecht in his office of Provost of Sint Servaas in Maastricht.
