[Manuscript] PROCEEDINGS of the sieurs de La Fond against the president Lamoignon. Paris, 1679-1729, in-4, 14 bundles of manuscript papers. The documents are classified, and put in a folder with the bag that originally contained them. The vast majority of the pieces are in good condition for handwritten pieces kept in burlap bags, with a complete and legible text. We note, however: Bag 10: one document on vellum is incomplete by two pages. Bag 11: one document is torn and incomplete. Bag 14: a register has been badly degraded by a major worm job. Small defects, otherwise, without consequences. Set of documents constituting the trial documents of the heirs of Jacques de La Fond claiming on the rights of inheritance, various claims incurred in the time of their grandfather. The lawsuit, which was to last more than twenty years and which called for acts prior to 1679, the date of Jacques de La Fond's death, was brought against eminent personalities of the time, including, in addition to the various curators of the estate, Jolly de Ménaiville, treasurer of France in Champagne, the marquis de La Trousse lieutenant general of the King's armies, the sieurs de Mouy and Chrétien de Lamoignon, the president of the parliament of Paris, protector of the inheritance from his first wife Louise Gon de Bergogne for the lands of Hauterive, Vassigny and Argenlieu. Jacques de La Fond (or La Fonds) occupied an important place in the royal administration and the world of finance in the second half of the 17th century, appearing in various acts as secretary to the King in his Council, and "keeper of the roles of the officers of France"; besides these honorary offices, he was "master of the requests to the county of Burgundy and drafts of the office of Bordeaux" close to the intendant of the generality of Montauban, then controller and receiver of the consignations in Touraine. He was said to be the lord of La Beuvrière in Lazenay, marquis of Paudy, and in particular the owner of the Chateau de La Ferté-Guibert which was enlarged when he was acquired in 1659 according to plans commissioned from François Mansart. At his death in 1679, his son Claude, knight lord of La Beuvière, seems to recover his father's heritage only in 1703. He was "King's counselor, honorary master of requests of his hotel", intendant in Franche-Comté and Alsace. He died in 1719 and the estate passed to his son Claude-Adrien, married to Mademoiselle de La Rivière. But he died in 1726, leaving an only minor son Charles-Jean born in 1720. It is his mother Louise Céleste de la Rivière, who later remarried to Sieur de Riffardeau, who will defend and plead the cause of the La Fond estate as Charles-Jean's guardian. The lawsuit dates back to the first inventories of the estate of Jacques de La Fond in April 1679. The first complaint is brought against the curator of the estate of Jacques de La Fond whose remains are estimated at the enormous sum of more than 600 000 livres. Also claimed were the arrears of the estate of Marguerite, sister of Claude de La Fond, married to the Marquis de La Trousse, from his descendants Jolly, sieur de Menaiville. The second and most important complaint was against François Levasseur, curator of the estate of Paul de Chaudessole seigneur d'Auterive, whose sole heiress was the wife of the president of the Parliament of Paris, Chrétien de Lamoignon. Paul de Chaudessole, secretary to the King, is mentioned for having received important claims advanced by Jacques de La Fond. The whole of the accounts being brought to verification at the Cours des Aydes, Lamoignon will oppose at first, and rightly, the right of prescription; in the same way, he opposes a renunciation to the succession of Jacques de La Fond dated 1712, by his children Claude and Marguerite, act confirmed by the nomination of a curator. Finally, there is a disagreement of 1703 between the widow of Mouy and the La Fond family about the reimbursements of the drafts of the generality of Montauban. Chrétien II de Lamoignon (1676-1729), was the son of the great Chrétien François de Lamoignon, president à mortier forming the elder Lamoignon branch, marquis of Basville. Two generations later, his grandson Chrétien François (1735-1789) became president of the Parliament of Paris and then in 1787, Gardes des Sceaux following Miromesnil. In the end, it seems that the La Fond heirs did not win their case; on the one hand, attacking a family as powerful as the Lamoignons seemed risky, on the other hand, the succession fell into the hands of the dead; Charles-Jean died without a spouse in 1740, his mother in 1756. Her husband, Charles-Jean de Riffardeau, recovered part of the estate, including the chateaux of La Ferté and Paudy and the lands of Diou.
