Upon her marriage, Claire assumed the feminine form of her husband’s titles, becoming a Princess of Luxembourg, with the style of Royal Highness, as stipulated by the 18 June 2012 House Law revisions by Prince Félix’s father, Grand Duke Henri.

Since the wedding, the couple has been living in the south of France at the Château Les Crostes, a winery in Lorgues that has been owned by the Lademacher family for many years.
