The cause of Rik Mayall's death is to be investigated at a post-mortem to be carried out on Thursday.
Actor and comedian Mayall died unexpectedly at his London home aged 56 on Monday, with his family still unaware of what the cause of death was.
His wife, Barbara Robbin, suggested he may have suffered a fit after a quad bike accident in 1998 had left him with epilepsy and needing daily medication.
A spokeswoman for West London Coroners' Court said: "The death has been referred to the West London Coroner and I understand a post-mortem examination may be carried out tomorrow."
An inquest may be held depending upon the result of the post-mortem.
Peter Richardson, who had worked with Mayall on The Comic Strip Presents, said his son had been "happily chatting away" with Mayall just half an hour before he died.
"He was happily chatting away [to my son] and then we still don’t know quite what happened but it was a seizure of some sort," he told Radio 4's Today programme.
"He had 16 years after the quad bike and I think that at the time people didn't think he would survive.
"But he lived for another 16 years and it was just shocking that he was so happy and seemed so healthy when he did go."

The passing of the star of The Young Ones and Bottom prompted an outpouring of emotion from his loved ones and the comedy world.
His daughter, Bonnie, paid an emotional tribute to her "wonderful, generous, foul-mouthed and hysterical" father.
She added: "We will never forget him and neither will the world.
"R.I.P to the man, the myth, the legend. My idol now and forever. We love you daddy."
A 'lost' World Cup anthem he had recorded in 2010 today breached the top 20 in the charts after a campaign was launched to get it to number one to honour his memory.
The song, called Noble England, has won the backing of legions of fans in an online campaign.
