Louis Alphonse's engagement to marry Venezuelan María Margarita Vargas Santaella, the daughter of the businessman Victor Vargas, was announced in November 2003. They were married civilly in Caracas on 5 November 2004 and religiously on 6 November 2004 in La Romana, Dominican Republic. None of the members of the Spanish royal family attended the wedding. Although no official reason was given, it was no secret that the then king, Juan Carlos I, did not approve his cousin's claim to the French throne, nor the fact that Louis Alphonse issued the wedding invitations styled as "Duke of Anjou". From 2005, the couple resided in Venezuela, where he worked at "Banco Occidental de Descuento", before moving to the United States. Subsequently, they took up residence in Madrid.
