Why Arizona Limits Each Custodianship to One Minor
This statute keeps things simple. A UTMA transfer cannot name multiple children as co-beneficiaries. Two people cannot share the custodian role for the same minor child's property. If you want to transfer assets to three grandchildren, you need three separate custodianships. Each one needs its own custodian designation and its own UTMA account or title.
A transfer may be made only for one minor and only one person may be the custodian. All custodial property held under this article by the same custodian for the benefit of the same minor constitutes a single custodianship.
A.R.S. § 14-7660The one-custodian rule also simplifies record-keeping and accountability. When questions arise about how the property was managed, there is one person who bears responsibility. There is no confusion about who had authority to invest, spend, or distribute the assets.
Practical Considerations for Families
Even though only one custodian can serve per minor, multiple transfers can go into the same custodianship. A grandparent could transfer securities, cash, and real estate to the same custodian for the same grandchild. All of those assets would be managed together as one custodianship. This makes it easier for the custodian to track investments and file tax returns.
If a family wants different people to manage different assets for the same child, they would need a different structure. A formal trust with co-trustees is one option. The Minors Act (UTMA) is designed for simplicity. This single-custodian rule is a core part of that design.
How Custodial Accounts Differ from Other Options
Many families compare custodial accounts under the Uniform Gifts to Minors Act (UGMA) with UTMA accounts. Both allow gifts to minors, but UTMA accounts can hold a wider range of assets. Under Arizona law, the minor reaches the age of majority and receives the property at age 21. Until that time, income in the account may be taxed at the child's tax rate. If the custodian can no longer serve, a successor custodian takes over. This means that the minor child's assets remain protected even if circumstances change.
In practice, families often choose between a UGMA account, a UTMA account, and other planning tools based on the type of asset and how long they want the custodian to maintain control. The reaching age for distribution is an important factor in that decision.
