The husband of millionairess Eva Rausing, who was found dead at her home last week, appeared in court on Wednesday charged with preventing the lawful and decent burial of her body.
Tetra Pak heir Hans Rausing, who looked frail in the dock at West London Magistrates' Court, spoke only to confirm his name, age and address.
The 49-year-old was granted conditional bail to appear again at Isleworth Crown Court on July 26.
Police discovered the decomposing body of mother-of-four Mrs Rausing after they arrested her husband on suspicion of driving under the influence of alcohol or drugs last Monday.
Mrs Rausing, one of Britain's richest women, was found in an annexe on the second floor of the opulent Cadogan Place house in London's Chelsea which she shared with her husband.
Police are treating the death as "unexplained" and a post-mortem examination held last week failed to establish a formal cause of death.
Rausing, whose family made a fortune when they sold the Tetra Pak business in the 1990s, was was wearing a dark suit and light blue shirt with no tie.
District Judge James Henderson told him: "I grant you bail on two conditions. The first is that you must reside at the Capio Nightingale Hospital and that you live there and sleep there overnight, and you do not leave that hospital unless you are accompanied by a member of hospital staff."
