A suicide pact is the decision of two or more people to die together. This event is rare. The majority of suicide pacts victims are married, socially isolated, with a serious physical illness in one or both partners. An objective element, such as a suicide note and motive, is required to prove that a suicide pact is involved. The prevalence of mental disorders is hard to assess. In France, psychological autopsies are not performed in such cases, as the investigation is usually very sparse after the death of both individuals.
