French prosecutors announced on Thursday that Swiss lawyer Alexandre Montavon has been placed under formal investigation for his alleged involvement over a decade ago in the misappropriation of millions of Hermes shares for the benefit of LVMH (LVMH.PA), opens new tab.
Placing a suspect under formal investigation is a step in the French legal system indicating there is serious evidence against a suspect, but that does not imply guilt.

The prosecutors mentioned, without providing further details, that they suspected Montavon was involved in the scheme through his role as a lawyer and administrator of an offshore company called Dilico.
Market watchdog AMF has previously stated that Dilico was used to transfer Hermes shares to banks associated with LVMH.
The procedural step demonstrates that Paris investigators are actively examining the circumstances under which LVMH built up its position in rival Hermes, a move LVMH first disclosed in 2010, sparking a years-long corporate feud between the two luxury giants.
Montavon was placed under formal investigation on charges of "complicity in breach of trust" on Wednesday, according to the Paris prosecutors.
Hermes heir Puech, 83, has sued Bernard Arnault and his LVMH group, among other parties, in a civil case claiming he was deprived of Hermes shares now valued at over €10 billion.
France’s market watchdog fined LVMH €8 million in 2013 for failing to properly disclose its stake-building in Hermes, which LVMH at the time called "baseless".
Arnault has consistently denied allegations of preparing a takeover of Hermes, one of the world’s most valuable luxury brands and a direct competitor to LVMH’s top brand Louis Vuitton.
Puech, once among Hermes’s largest individual shareholders, claimed in a rare interview with French magazine L’Express last year that he had unwittingly lost control of his massive stake.
In a criminal complaint filed in Paris in December 2023, Puech alleged breach of trust and misappropriation of his assets by his now-deceased former wealth manager Eric Freymond and possible associates.
Freymond, who managed Puech’s fortune for more than 20 years, died in July 2025 while under investigation. Swiss authorities have stated they were investigating a possible suicide.
