When the Trustee's Duties Begin
A custodial trustee does not take on responsibilities simply by being named in a document. The obligations arise only when the trustee actually accepts the custodial trust property. That acceptance can be express (a formal written acknowledgment) or implied (by taking actions consistent with serving as trustee).
Obligations of a custodial trustee, including the obligation to follow directions of the beneficiary, arise under this chapter on the custodial trustee's acceptance, express or implied, of the custodial trust property.
A.R.S. § 14-9104(A)This is an important protection for anyone named as a custodial trustee. You are not automatically locked into the role. Until you accept the property or begin managing it, the duties and liabilities of trusteeship have not attached to you.
The Acceptance Form and Court Jurisdiction
Arizona provides a standard written form that custodial trustees can use to formally accept the role. The form acknowledges receipt of the trust property, identifies the beneficiary, and confirms that the trustee agrees to administer and distribute the property according to the Uniform Custodial Trust Act.
The form also includes an important note: the trustee's obligations are subject to the beneficiary's directions, unless the beneficiary is or becomes incapacitated. When incapacity occurs, the trustee manages the property according to the standards in the act rather than taking direction from the beneficiary.
On accepting custodial trust property, a person designated as custodial trustee under this chapter is subject to personal jurisdiction of the court with respect to any matter relating to the custodial trust.
A.R.S. § 14-9104(C)Once a trustee accepts, they are subject to the jurisdiction of Arizona's superior court for any matter related to the trust. This gives beneficiaries and other interested parties a clear path to seek court oversight if disputes arise about how the trust is being managed.
