Further tests are to be carried out on the body of Sally Clark, who was wrongly convicted of the murder of her two sons, to establish how she died.
Sally Clark spent three years in jail after her wrongful conviction
Solicitor Mrs Clark, 42, was found dead at her home in Hatfield Peverel near Witham, Essex, on Friday.
An inquest heard that she probably died of natural causes but more tests were needed to find a definitive cause.
She was found guilty of murdering eight-week-old Harry and 11-week-old Christopher in 1999 but later cleared.
Mrs Clark appeared to have died of natural causes, Monday's inquest in Chelmsford, Essex, was told.
Coroner Caroline Beasley-Murray heard that further medical tests were needed.
The coroner was told that Mrs Clark's body had been found by one of her friends.
Mrs Clark spent three years in jail for the murder of her two sons, before she was cleared by the Court of Appeal in January 2003.
A family statement following her death said she "never fully recovered from the effects of this appalling miscarriage of justice".
Mrs Clark, who was originally from Wilmslow in Cheshire, was convicted of smothering Christopher and shaking Harry to death at the home she shared with her husband Stephen.
The children died within 14 months of each other and jurors had to decide whether the deaths were natural.
The expert evidence of paediatrician Professor Sir Roy Meadow was a focal point during her trial and appeal.
He told jurors there was a "one in 73 million" chance of two children dying from cot deaths in an affluent family.
But the figure was disputed by the Royal Statistical Society and other medical experts who said the odds of a second cot death in a family were around one in 200.
Three Court of Appeal judges eventually decided that her conviction was "unsafe".
Mrs Clark's husband Stephen, also a solicitor, moved to Essex following her conviction.
Mrs Beasley-Murray adjourned the inquest to a date to be fixed.
