In most cases, nothing happens when your child turns 18. Arizona’s Uniform Transfers to Minors Act (UTMA) generally holds a custodial account until age 21 — not 18 — when the money came from a gift, a will, or a trust. The account terminates at 18 only for a narrower category of transfers. So for the typical UTMA account a parent or grandparent opens, the child gets full control at 21.
This surprises a lot of Arizona families, because 18 is the age of majority for most other purposes. Under the UTMA, the trigger age depends on how the account was funded.
Age 21 vs. age 18 in Arizona
Arizona’s UTMA lives at A.R.S. §§ 14-7651 through 14-7671, and the termination rule is in § 14-7670:
- Age 21 — for property transferred by gift, or through a will or trust (A.R.S. §§ 14-7654, 14-7655). This covers most custodial accounts opened for a child by a parent, grandparent, or other donor.
- Age 18 — for other transfers, such as property that already belonged to the minor or was owed to them (A.R.S. §§ 14-7656, 14-7657) — for example, certain settlements or funds from an obligor.
At the trigger age, the custodian must transfer the account outright to the young adult. There is no option under the UTMA to hold it longer. Whatever is left becomes theirs to spend however they choose.
What if you want control past 21?
If handing a 21-year-old a lump sum concerns you — and for larger amounts, it often should — a custodial account may not be the right tool. A trust can hold assets well beyond 21, release money in stages, and add protections a UTMA account simply can’t. And if your child has a disability, a specialized plan matters even more, because an outright transfer can jeopardize public benefits.
Related questions
Can a UTMA account in Arizona be extended past age 21?
No. The Arizona UTMA requires the custodian to transfer the property to the beneficiary at the statutory age. To keep control longer, the money needs to be held in a trust instead of a custodial account.
Who owns the money in an Arizona UTMA account?
The minor does. Custodial property belongs to the child from the moment it’s transferred; the custodian only manages it for the child’s benefit until the account terminates. It is not the parent’s money.
Is a UTMA account the best way to leave money to a minor in Arizona?
It’s simple and inexpensive, which makes it fine for modest amounts. For larger gifts or inheritances, or for a child with special needs, a trust usually gives you far more control and protection.
