In 1984, Clermont and Marie-Thérèse were divorced. On 31 October 1984 Clermont entered a civil marriage with Micaëla Anna María Cousiño y Quiñones de León (born on 30 April 1938), daughter of Luis Cousiño y Sebire and his wife Antonia Maria Quiñones de Léon y Bañuelos, 4th Marquesa de San Carlos, and who had previously been divorced from Jean-Robert Bœuf. For remarrying without consent, Henri's father initially declared him disinherited, substituting the non-dynastic title "Comte de Mortain" for his son's Clermont countship (the latter once held in appanage by a son of Louis IX of France, who became ancestor of the Bourbon-Orléans line). Henri, though, refused all mail addressed to him as "Mortain". On 27 February 1984 Marie-Thérèse, the former Countess of Clermont, was granted the title "Duchess of Montpensier" by her father-in-law.
