Marie-Joseph Experton

Marie-Joseph Experton is a French avocat (attorney at law) admitted to the Paris Bar who established a permanent secondary practice in Brussels under EU Directive 98/5/EC. She operated through Cabinet Experton SPRL (Belgian company number BE 0860.831.646), a micro-enterprise at Avenue Louise 150, Brussels, founded in September 2003 and closed in May 2024. Experton appears in 906 OCR-searchable documents and 623 emails in the DOJ's EFTA release, making her one of the most extensively documented professionals in the Epstein files. The earliest evidence places her receiving FedEx packages from Epstein's 457 Madison Avenue office in May 2002. The last documented payment, a wire transfer of $2,819.13 (EUR 2,375) for legal fees covering April through June 2019, was processed on July 9, 2019, three days after Epstein's final arrest. In January 2008, HSBC's Paris branch closed Epstein's French account over suspicious activity.

Bloomberg reported this was the only known instance of a major bank cutting ties with Epstein before his 2008 plea deal. Experton coordinated the response with Darren Indyke, reaching the bank officer who cited "account activity" as the reason and refused to elaborate. Experton managed Epstein's Paris property at 22 Avenue Foch through a French shell company called SCI JEP (SIREN 441 627 171), in which Epstein held 99.99% of shares. She chaired co-owners' general meetings as the SCI JEP representative and coordinated maintenance with Valdson Cotrin (property manager) and Jean Huguen (interior designer).

In 2013, Experton purchased a Mercedes S 500 for Epstein's use in Paris, transferring EUR 70,000 from her own Belgian bank account to the dealership. Mercedes flagged the wire because it originated from a lawyer's account rather than Epstein's, requiring additional clearance. She had also managed a EUR 10,833 Mercedes repair in 2012. In September 2015, Epstein described her role in an email to Paris lawyer Henri d'Armagnac: "I use a female lawyer from belgium for my personal things." She is listed in Epstein's black book.

Cabinet Experton SPRL was closed on May 21, 2024, with negative equity of EUR 8,856. SCI JEP had been dissolved three months earlier, on February 29, 2024. Both entities that anchored Epstein's European legal infrastructure were wound down within months of each other, five years after his death. Experton has not been charged with any crime and has not, as far as public records indicate, been questioned by any law enforcement agency about her role.
