Arizona gives you broad freedom to choose who inherits from you. You can leave adult children, siblings, or any other relative out of your will or trust. But for your spouse, the rules are different. Knowing those limits is key to making your estate plan hold up.
Disinheriting Adult Children and Other Relatives
Arizona law does not require you to leave anything to adult children, grandchildren, siblings, or anyone else. You can state in your will or trust that a certain person gets nothing. The key word is clearly. If you just leave someone out without saying so, a court might think it was a mistake. This is more likely if the person was born or adopted after the paper was signed.
To make your intent clear, name the person and state that you are leaving them nothing on purpose. This removes doubt. It also makes it much harder for anyone to fight your wishes in court.
What About Minor Children?
You cannot fully cut out minor children from all support. Arizona law protects minors. This includes homestead rights, exempt property, and a family allowance that applies no matter what the will says. But you can set up your estate plan so minor children get only what the law requires. An estate planning lawyer can help you set these limits the right way.
The Spousal Exception: Community Property Rules
Arizona is a community property state. Assets gained by either spouse during marriage (except gifts and inherited items) belong equally to both spouses. Your spouse already owns their half of all community property. You cannot give away your spouse's half in your will. It was never yours to give.
Under A.R.S. 14-2102, your surviving spouse has rights to community property, the homestead, exempt property, and a family allowance. These rights apply no matter what your will says.
Can a Spouse Be Partially Disinherited?
You can leave your spouse less than half of your separate property. Separate property is what you owned before marriage or got as a gift or through inheritance. Arizona does not have an "elective share" law like many other states. There is no set right for a spouse to claim a fixed share of your total estate. But community property rules already lock in the spouse's half of marital assets.
A prenuptial or postnuptial agreement can spell out exactly what each spouse gets. Without one, your spouse's community property rights stay in place.
Watch Out for Beneficiary Designations
Cutting someone out of your will does not remove them from other assets. Life insurance, retirement plans like IRAs and 401(k)s, and payable-on-death accounts all pass by who is named on them, not by your will. If you want to leave someone out fully, check every single designation. Missing even one can undo your whole plan.
Making Disinheritance Stick
For relatives, a clear statement of intent usually works. For a spouse, the focus shifts to sorting community property from separate property. You need to know which assets you can actually control. An Arizona estate planning attorney can make sure your papers match your wishes and hold up to any challenge. Planning now prevents family fights later. Simple as that.
