Loss of life by two or more individuals concurrently or pursuant to circumstances that render it impossible to ascertain who predeceased whom.
The issue of who died first frequently arises in cases determining the inheritance of property from spouses who die simultaneously. Generally the answer must be derived from all the surrounding circumstances. At common law, the law would not intervene and make the assumption that one individual or another had died first but would await proof, no matter how slight that might be. Since this created a problem when no satisfactory proof existed, various states enacted statutes allowing judges to presume that one individual survived another under certain circumstances.
Because those state statutes that created presumptions proved inadequate, a majority of the states enacted the Uniform Simultaneous Death Act. Although some slight variations exist from one state to another, the law essentially provides that property will be inherited or distributed as if each person had outlived the other. This prevents the property from passing into the estate of a second person who is already deceased only to be distributed immediately from that estate, a wasteful procedure that precipitates additional legal proceedings, costs, and estate taxes.
The Simultaneous Death Act cannot be applied if evidence exists that one individual outlived the other. The act only applies when it cannot be determined who died first. Ordinarily the persons involved need not have died in a common disaster but might have died in different places and under different circumstances, and it still might be impossible to prove that one survived the other.
