Simultaneous Death

noun

/ˌsaɪməlˈteɪniəs dɛθ/

In a Nutshell

When two or more people die at the same time or in circumstances where order of death cannot be determined.

PLAIN ENGLISH

Simultaneous death is when two people die at the same time (like in a car accident or plane crash) and you can't tell who died first. The law treats each person as if they died before the other for inheritance purposes, preventing property from passing through both estates unnecessarily.

⏱ When you'll encounter this term

  • Accidents involving multiple family members
  • Estate planning with survivorship clauses in wills
  • Insurance policies with multiple beneficiaries
  • Joint ownership situations after common disasters
EXAMPLE

"A couple died in a car crash, and medical evidence couldn't establish who died first. Under simultaneous death laws, the husband's estate was distributed as if his wife had predeceased him, and her estate was distributed as if he had predeceased her—meaning each estate went to their respective families rather than through each other."

⚖️ Compare: Simultaneous Death vs Survivorship Clause

Simultaneous Death

Legal presumption when death order unknown. Statutory rule applying automatically. Each deemed to predecease the other.

Survivorship Clause

Voluntary provision in will. Requires beneficiary survive by specified period (e.g., 30 days). Planned protection against common disasters.

💡 Did you know?

Most well-drafted wills include a survivorship clause requiring beneficiaries to survive the testator by 30 days or so, which effectively overrides simultaneous death statutes and prevents assets from passing briefly to a deceased spouse and then immediately to their estate.
