Because his father, Gerhard (or Heralt) was chamberlain (Czech: Komorník) at the courts in Brno and Znojmo, Boček probably grew up in Moravia.
Before 1350, Boček went to Bohemia, where he presumably held some office at the court in Prague and acquired the favor of King Charles IV.
From 1353 to 1358, Boček held the office of cup-bearer (Czech: Číšník) at the court of Charles IV.
After he lost the favor of the king, he sought to broaden his family possessions in Bohemia and Moravia.
As he had built the castle without permission, King Charles IV and his brother, Margrave John Henry, ordered its destruction.
