often addressed as a prince. From his birth, Alfonso was considered a prince du sang by those legitimists who believed that Alfonso XIII was also the heir to the French throne. When his grandfather died on 28 February 1941, Alfonso's father Jaime succeeded him in this French claim; Alfonso was thereupon recognised by the legitimists as Dauphin of France. On 25 November 1950, Alfonso received the title Duc de Bourbon (Duke of Bourbon) from his father. In 1963, Alfonso engaged the French historian and ardent royalist Hervé Pinoteau as his private secretary. Pinoteau remained with him until the duke's death. On 20 March 1975, Alfonso's father Jaime died; he was immediately recognised by his supporters as King Alphonse II of France. On 3 August 1975, he took the courtesy title Duc d'Anjou (Duke of Anjou). On 21 January 1985 (the 192nd anniversary of the death of King Louis XVI) Alfonso was present for the requiem mass at the Chapelle expiatoire in Paris.

Lawsuit of the Count of Clermont against the Duke of Anjou In 1987, Prince Henri of Orléans, Count of Clermont, eldest son of Henri, Count of Paris, the then Orléanist claimant to the defunct throne of France, initiated a court action against Alfonso for his use of the title Duke of Anjou and the coat-of-arms France Moderne (three fleur-de-lis or); Henri asked the court to fine Alfonso 50,000 French francs for each future violation. In 1988, Prince Ferdinand, Duke of Castro and Prince Sixtus Henry of Bourbon-Parma joined Henri's lawsuit in reference to the use of the title Duke of Anjou, but not in respect to the coat-of-arms. On 21 December 1988, the Tribunal de grande instance of Paris ruled that the lawsuit was inadmissible because the title's legal existence could not be proven; that neither the plaintiff (Henri) nor the intervenors (Fernando and Sixtus) had established their claims to the title; and that Henri was not injured from the use of the plain arms of France by the Spanish branch of the Bourbon family. In 1989, Prince Henri d'Orléans and Prince Sixtus Henry of Bourbon-Parma appealed the judgment
