[1] Misadventure in English law, as recorded by coroners and on death certificates and associated documents, is a death that is primarily attributed to an accident that occurred due to a risk that was taken voluntarily.
In contrast, when the manner of death is given as an accident, the coroner has determined that the decedent had taken no unreasonable willful risk.
[1] "Misadventure may be the right conclusion when a death arises from some deliberate human act which unexpectedly and unintentionally goes wrong.
For example, a death caused by an illicit drug overdose may be ruled a death by misadventure, as the user took the risk of drug usage voluntarily.
[1] In the case of R v Wolverhampton Coroner,[3] it was held that the coroner must establish death by misadventure on the balance of probabilities, commonly known as "more likely than not".
