Most couples build an estate plan assuming one spouse will outlive the other. However, what happens if both spouses die in the same accident? What if one spouse survives by only a few hours or days?

These situations can create complicated questions about inheritance, trusts, beneficiary designations, and probate. Fortunately, Arizona law provides specific rules for handling these circumstances.

Understanding simultaneous death estate planning in Arizona can help families prevent uncertainty. More importantly, careful planning can ensure assets ultimately reach the people you intended to protect.

Arizona Uses a 120-Hour Survivorship Rule

Arizona generally applies a 120-hour survivorship requirement when determining who inherits property.

Under Arizona law, a beneficiary who cannot be proven to have survived another person by 120 hours is generally treated as having died first. In other words, surviving by only several minutes, hours, or even a few days may not qualify someone as the surviving beneficiary.

The 120-hour period equals five days.

For example, suppose a husband and wife are involved in the same serious accident. The husband dies immediately. His wife survives for two days before passing away.

Without another applicable estate planning provision, Arizona’s survivorship rules may treat the wife as if she predeceased her husband for certain inheritance purposes.

This rule can prevent property from unnecessarily moving through two estates within several days.

Why Simultaneous Death Estate Planning in Arizona Matters

The order of death can dramatically affect where property ultimately goes.

Consider a married couple with children from previous relationships. Each spouse may want certain assets to benefit their own children after both spouses die.

Without clear instructions, however, the order in which the spouses legally die could potentially change which family members inherit property.

Similar issues can arise with:

• Revocable living trusts
• Last wills and testaments
• Jointly owned property
• Retirement accounts
• Life insurance policies
• Transfer-on-death accounts
• Payable-on-death accounts
• Business interests

Therefore, simultaneous death planning is not simply about rare disasters. It is about removing ambiguity from an estate plan.

Can Your Estate Plan Override Arizona’s 120-Hour Rule?

Arizona law provides important exceptions to its general 120-hour requirement.

For example, the rule does not necessarily apply when an estate planning document specifically addresses simultaneous deaths or deaths resulting from a common disaster. An estate plan may also establish its own survivorship period.

That flexibility makes carefully drafted estate planning documents particularly valuable.

An attorney can help determine how property should pass if spouses or other beneficiaries die close together. Additionally, the documents can identify alternate beneficiaries when someone does not survive the required period.

Consequently, your wishes can provide clearer guidance instead of relying entirely on statutory defaults.

What Happens to Jointly Owned Property?

Jointly owned property can create another layer of complexity.

Arizona law addresses certain property owned with rights of survivorship. When neither owner can be proven to have survived the other by 120 hours, the property may be divided as though each owner survived the other for their respective portion.

However, ownership structure matters.

Therefore, couples should not assume that adding someone to an account or property title automatically creates their desired estate planning outcome.

Instead, ownership arrangements should work together with wills, trusts, and beneficiary designations.

Revocable Living Trusts Can Provide Greater Control

A revocable living trust can provide detailed instructions for managing and distributing assets after death.

Dana Law Group explains that properly funded living trusts can allow assets to pass according to trust instructions outside the probate process. They can also specify successor trustees and establish how beneficiaries receive their inheritance.

For simultaneous death estate planning in Arizona, trusts can provide particularly valuable flexibility.

For example, a trust can specify what happens if one spouse does not survive the other for a designated period. It can then direct property toward children, grandchildren, charities, or other beneficiaries.

Furthermore, trusts can provide ongoing management rather than immediately distributing everything outright.

Beneficiary Designations Need Attention Too

Creating a will or trust is only part of an effective estate plan.

Many significant assets transfer through beneficiary designations or ownership arrangements. Dana Law Group notes that properly funding an estate plan may involve transferring assets into a trust or appropriately naming beneficiaries.

Therefore, families should review:

• Life insurance beneficiaries
• Retirement account beneficiaries
• Bank and investment accounts
• Real estate ownership
• Business ownership documents
• Transfer-on-death instructions

Contingent beneficiaries are especially important.

If your primary beneficiary dies with you, the contingent beneficiary may determine where significant assets ultimately go.

Blended Families May Face Additional Complications

Simultaneous death scenarios deserve special attention in blended families.

Suppose each spouse entered a marriage with children from an earlier relationship. Both spouses may want to provide for each other while ultimately leaving property to their respective children.

Now imagine both spouses die within several days.

Without carefully coordinated estate documents, beneficiary designations, and survivorship instructions, the eventual distribution may differ significantly from what either spouse expected.

That is why customized planning matters.

Estate planning should reflect your family structure rather than relying on a generic document or assumptions about Arizona inheritance laws.

When Should You Review Your Estate Plan?

You do not need to wait for a major life crisis to examine your documents.

Consider reviewing your estate plan after marriage, divorce, the birth of a child, acquiring significant property, starting a business, or experiencing major financial changes.

You should also review older documents periodically.

Estate planning laws change. Additionally, your relationships, assets, beneficiaries, and priorities can change considerably over time.

A review allows you to confirm that your survivorship language still reflects what you actually want.
