	Following the decline of the Kőszegis' power, his relationship with Charles I had normalized. He spent much of his time in the royal court at Visegrád. He was a founding member of the Order of Saint George on 24 April 1326, the first secular chivalric order in the world. He attended a provincial synod in Esztergom on 8 November 1326, where he acted as an arbiter in the lawsuit between Boleslaus of Esztergom and Henry of Veszprém. Kőszegi and Nicholas Dörögdi represented the interests of the archbishop, while Csanád Telegdi and John, archdeacon of Hont were appointed as trustees of Henry. From 1326 to 1331, Kőszegi acted as co-judge alongside Judge royals Alexander Köcski, then Paul Nagymartoni several times. Kőszegi countersigned the peace treaty between Charles and the three dukes of Austria in Bruck an der Leitha on 21 September 1328. He summoned a general assembly in Vas County in July 1330, upon the request of the king.
