Their relationship eventually fell apart, and Frederik Christian tried to legally limit her influence over their children's future. He died on 14 June 1814, and Louise Augusta took control of the Augustenborg estates and the children's upbringing. The estate was turned over to the eldest son, Christian August, on his return from an extended foreign tour in 1820. From then on she resided in the Augustenborg Castle, where she established an eccentric court. In 1832 in order to give her youngest son, Frederik Emil August, better income possibilities she purchased the estate Nør and Grønwald in Dänischwold near Ekernførde Fjord in South Schleswig. She had a close and warm relationship with her daughter and her son-in-law, but her relationship to her sons was tense.
