The Man Ray Trust said in 2021 that 148 of 188 lots in a Christie's Paris sale of his assistant's collection lacked clear title; Christie's sold them

Man Ray married Juliet Browner in 1946. When he died in 1976 she founded the Man Ray Trust. After she died in 1991 her family continued it. His assistant Lucien Treillard died in 2004. Christie's set a sale of 188 lots from the Treillard collection in Paris on 2 March 2021, postponed from early 2020 because of Covid-19. The Trust said 148 of 188 items lacked clear title. It alleged Treillard "stole a substantial number of Man Ray's works and possessions immediately following his death." Its spokesman, Matt Browner Hamlin, a great-nephew of Juliet, said French law gave a possessor title to stolen goods after 30 years, a period that he said had just run out. Treillard had denied removing works from the studio. The Christie's catalogue notes that he made prints and reproductions, and he had admitted falsely authenticating Man Ray works. Christie's said it had consulted the Man Ray committee and that nothing it received gave grounds to challenge the legality of the sale. The sale went ahead. Separately, a forgery ring producing "vintage" Man Ray prints was exposed in the late 1990s^†. These are allegations by the Trust, not court findings.
