The former Sarah Ferguson plans to move to Switzerland for good this fall, according to the July issue of Biography magazine.
Ferguson will establish her new home when her daughter Beatrice starts her term in a Swiss school. Prince Andrew, her former husband, will stay in England with the couple's other daughter.
"We insist on being co-parents," Ferguson told the magazine.
Last week marked a thaw between the queen and the Duchess of York when Ferguson made it on the royal guest list for Prince William's birthday.
"Look, I'm doing pretty well, considering. You know, in the past, when anyone left the royal family, they had you beheaded!" she said.
