Although his father had asked in his will that they rule jointly, the brothers divided their inheritance among themselves in 1434 or 1435.
As their guardian, he sold William's 2/3 share of the Opava to Duke Bolko V of Opole, after 1454.
On 8 March 1456, he sold the Duchy of Münsterberg to the provincial administrator and future King of Bohemia, George of Poděbrady.
Bolko V died in 1460 and his heir Nicholas I sold the 2/3 share of Opava to George of Poděbrady.
In 1464, George purchased the remaining third from John II, thereby significantly increasing his political and economic influence in Silesia.
