Queen Sophie did not live at the Danish court as queen, but resided separated from her spouse on her property in Kiel, and treated her estates as her private independent fiefs, which caused disagreements with her spouse during his reign.
In 1533, she became a widow and moved to Gottorp Castle with her children, awaiting the outcome of the election of the new king.
In 1538, her stepson, the new king, Christian III, asked her to leave Gottorp because of the costs and reside in Kiel.
