Yes — in Arizona you can disinherit an adult child, but you have to do it clearly and correctly. Arizona does not force you to leave anything to an adult child. The key is stating your intent explicitly in a valid will or trust, because silence can be read as an accident rather than a choice. Disinheriting a spouse is a different story.
How to disinherit an adult child the right way
Don’t simply leave the child out and hope it’s understood. Name the child in your will or trust and state directly that you are intentionally not providing for them (you don’t have to explain why). Clear language prevents a later claim that you simply forgot. A small, specific gift or a “no-contest” clause can further discourage a challenge.
Skip the old “leave them $1” myth
A popular myth says you should leave a disinherited child $1 to “make it official.” Don’t. Leaving them even a dollar makes the child a beneficiary of your estate — an interested party who is then entitled to all the statutory notices, the inventory, and the accountings, and who has to be dealt with throughout the administration. That usually creates more friction, not less. The cleaner approach is to name the child and state plainly that you are intentionally leaving them nothing — no ambiguity, and no unnecessary role for them in settling your estate.
Two important Arizona limits
- Children born or adopted after your will (pretermitted children). Arizona law protects a child born or adopted after you sign your will who isn’t mentioned or provided for — they may still inherit a share unless your documents address the possibility. Update your plan after a new child or grandchild.
- You generally cannot disinherit a spouse the same way. Arizona is a community-property state, so your spouse already owns half of the community property. There are also protections for an omitted spouse. Cutting out a spouse requires careful planning (and often a valid prenuptial or postnuptial agreement).
Consider the alternatives
Total disinheritance isn’t the only option. Many families instead use a trust to leave an inheritance with conditions or protections — for example, holding funds for a child who struggles with money, addiction, or a shaky marriage — rather than cutting them off entirely. That often reduces conflict and resentment while still protecting your wishes.
Disinheritance is one of the easiest places for a plan to be challenged. Schedule a free consultation so your intentions hold up.
