When he came of age, Balthasar chose an ecclesiastical career.
He was coadjutor of the Diocese of Hildesheim in the years 1471-1474 and then in the Diocese of Schwerin from 1474 to 1479. He probably was not satisfied with ecclesiastical life and returned to lay status in 1479. After Magnus died, Balthasar ruled jointly with Magnus" sons.
Balthasar died on 16 March 1507 (or, less likely, on 17 March) in Wismar and was buried in the Doberan Abbey in Bad Doberan.
They had no children.
