The Act stated that the two branches will recognize each other's titles for the present holders and their successors; the titles of the senior, Spanish line, being Duke of Calabria, Duke of Noto and Duke of Capua, and of the junior line, being Duke of Castro and Duchess of Palerma and Duchess of Capri which were accorded to the Duke and Duchess of Castro's two daughters. The final intention was to work together to unite the Constantinian Order as well as perhaps share the grand mastership of the Two Sicilies Order of St. Januarius (the revival of the Order of Francis I has never been accepted by the senior, Spanish line.)
