This is a question most married couples think about but rarely plan for. A car accident, a plane crash, or a sudden medical emergency could take both parents at once. Arizona state law has a specific rule for when spouses die at the same time. Understanding it helps families make sure their children and assets are protected.
Arizona's 120-Hour Survival Rule
Under A.R.S. 14-2702, if two people die within 120 hours (five days) of each other and it cannot be proven who survived longer, each person is treated as if they died first. This state law applies to wills, trusts, beneficiary designations, insurance policies, and jointly held accounts.
Arizona adopted this approach from the Uniform Simultaneous Death Act, which many states use. The goal is simple. When a married couple has died simultaneously, the law needs a fair way to decide how assets are distributed.
In practical terms, if you and your spouse are in a car accident and neither can be shown to have survived the other by five full days, your estate passes as if your spouse died first. Your spouse's estate passes as if you died first.
What Happens to Your Assets
If your will or trust leaves everything to your surviving spouse and your spouse is treated as having predeceased you, the assets go to your contingent beneficiaries. For most families, that means the children.
If you did not name contingent beneficiaries, Arizona's intestacy laws decide who inherits. A judge, not your family, makes that call.
For jointly held property with right of survivorship, the 120-hour rule splits the property in half. One half passes through your estate. The other half passes through your spouse's estate. The same applies to community property with right of survivorship.
Life insurance works the same way. The proceeds go to the contingent beneficiary on the policy, not the primary beneficiary who is treated as having died first. If there is no contingent beneficiary listed, the money may default to the estate and go through probate.
What Happens to Your Kids
If both parents die and minor children survive, the guardian named in the will steps in. This is one of the most important reasons to have a will, even for families with a trust. A will is the only document that names a guardian for children. A trust cannot do this.
If no guardian is named in either parent's will, the court appoints one. A judge who does not know your family makes that decision. Family members may petition for guardianship. If multiple people compete, the process can become stressful and expensive. Blended families face even more complexity when stepchildren and biological children are involved.
What a Good Estate Plan Should Include
A well-drafted estate plan accounts for the possibility that both spouses die at the same time. The documents should include:
- Contingent beneficiaries in the will, trust, and on every beneficiary designation.
- A guardian nomination in the will for minor children, plus a backup guardian in case the first choice cannot serve.
- A children's trust inside the revocable living trust that holds and manages assets for the kids until they reach an age the parents choose.
- A distribution plan that does not depend entirely on one spouse surviving the other.
No one wants to think about this scenario. But the families who plan for it give their children the greatest gift: certainty about who will care for them and how they will be provided for.
