Last March, Pr. Jean was condemned to leave Maison Philidor, a manor house near the Royal Chapel of Dreux, where he lived with his family and his mother often sejourned, and pay an indemnity to Fondation Saint-Louis.

The court of Dreux decided that he had no legal right to live in Maison Philidor and that he had to give it back to the Fondation Saint-Louis, its legal owner.

AFAIK, Fondation Saint-Louis was created by Jean's grand-father, Pr. Henri, to reunite what was left from the vast inheritance that the CoP received and sold/lost/gave away to prevent its dismemberment by the Count's vast family with whom he entertained tense relations.

But OTOH Jean seems to be President of Honnour of the said Fondation de Saint Louis

Is it the same Fondation ?
Did his grand-father appointed him President of Honnour of the Fondation as Jean seemed to be one of the few family members Henri got along with after disinheriting his son ?
Did he self-appointed himself ?
