How Posthumous Children Affect Future Estates in Arizona

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

When a property interest is set up for someone's heirs, issue, or children, a child born after that person's death is treated as though they were born before. A future estate that depends on someone dying without heirs can be defeated if a posthumous child is born who qualifies to inherit.

Title 33, ESTATES

azleg.gov

What This Statute Covers

Estate plans and property arrangements sometimes create future interests that depend on the existence of heirs, issue, or children. This statute addresses what happens when a child is born after the parent has already passed away. In short, Arizona law treats that child as if they were born before the parent died, giving them the same rights as any other heir.

When a future estate is limited to heirs, issue or children, posthumous children shall take as if born before the death of the parent.

A.R.S. § 33-237(A)

This matters in situations where a spouse is pregnant at the time of the property owner's death. Without this provision, the unborn child could be excluded from an inheritance or future interest simply because they had not yet been born. Arizona law closes that gap.

When a Future Estate Hinges on "No Heirs"

Some property arrangements include a condition that triggers only if the owner dies without heirs, issue, or children. This statute provides that if a posthumous child is born who is capable of inheriting by descent, that condition is no longer met.

A future estate contingent upon the death of a person without heirs, issue or children is defeated by birth of a posthumous child of such person, capable of taking by descent.

A.R.S. § 33-237(B)

The practical effect is straightforward: the birth of a qualifying child after the parent's death can change who ultimately receives the property. For families dealing with these circumstances, working with experienced estate planning counsel helps ensure the child's rights are properly recognized and protected.

What happens if I do not name a guardian for my minor children?

Without a named guardian, the court decides who raises your children. Judges do their best, but they do not know your values or wishes. Naming a guardian in your will gives you control over this decision.

How can I prevent family conflict over my estate plan?

The most effective way to prevent conflict is to put your intentions in writing with clarity. Spell out who receives what, who manages the estate, and explain your reasoning if shares are unequal.

What happens if I die without a will in Arizona?

Without a will in Arizona, your assets are distributed according to state intestacy laws. The court decides who receives your property using a fixed formula based on family relationships.
