In 1497, at the age of seven, he and his elder brother Jan IV were knighted at Pardubice Castle by King Vladislaus II, who was on his way from Prague to Hungary.

In the same year, he inherited Chlumec nad Cidlinou from Vilém Kostka of Postupice, the father of his first wife, even though he had since remarried.

This may have been the reason why he lost the post of High Hofmeister, which King Louis II of Bohemia and Hungary temporarily gave to Charles I, Duke of Münsterberg-Oels.

In this case, the original owner had been Opatovice Monastery, which had been destroyed during the Hussite wars, this confirmation virtually assured that Vojtěch would be allowed to keep these possessions.

Although Vojtěch had lost he post of High Hofmeister, he still exerted considerable influence until King Louis II died in 1526.

Vojtěch was considered a candidate to succeed him, along with Charles I of Münsterberg-Oels, Frederick II of Legnica and Zdeňek Lev of Rožmitál.

Since he had no male heir, his brother Jan IV inherited his entire estate, except for a small share for Vojtěch's daughters.
