The Building Blocks of a Custodial Trust
Before understanding how custodial trusts work, you need to know the key definitions. These definitions matter because they set who has authority, who benefits, and what triggers protections. They apply to every type of property in a custodial trust.
"Custodial trust property" means an interest in property transferred to or held under a declaration of trust by a custodial trustee under this chapter and the income from and proceeds of that interest.
A.R.S. § 14-9101(4)A custodial trust is a simplified trust arrangement. The transferor places property with a custodial trustee for a named beneficiary. The trustee holds legal title. The beneficiary holds the beneficial interest.
This structure makes it easier to manage assets for someone who may not be able to handle them alone.
When Incapacity Changes the Rules
One of the most important definitions here is "incapacitated." Under this act, a person is treated as incapacitated when they cannot manage property and business affairs. The causes range from mental illness to physical disability, substance use, confinement, or disappearance.
"Incapacitated" means lacking the ability to manage property and business affairs effectively by reason of mental illness, mental deficiency, physical illness or disability, chronic use of drugs, chronic intoxication, confinement, detention by a foreign power, disappearance, minority or other disabling cause.
A.R.S. § 14-9101(7)This definition is significant. When a beneficiary becomes incapacitated, the trustee's authority shifts. Instead of following the beneficiary's directions, the trustee manages the property on their own.
Families should also pay attention to how "member of the beneficiary's family" is defined. This term includes spouses, children, parents, siblings, and several extended relatives. Knowing who qualifies can affect who may serve as trustee or receive trust property.
