Exclusive Authority Over Trust Administration
If a trustee or beneficiary needs to go to court about how a trust is being run, there is only one place to go: the superior court. This statute draws a clear line.
Trust administration disputes belong only in superior court. This includes questions about distributions, trustee conduct, and accounting.
The superior court has exclusive jurisdiction of proceedings in this state brought by a trustee or beneficiary concerning the administration of a trust.
A.R.S. § 14-10203(A)This means you cannot file trust cases in justice courts or municipal courts. If a beneficiary believes a trustee has breached a duty, the superior court is the only option.
Claims about undue influence over trust terms also belong in this court.
Shared Authority for Other Trust Matters
Not every legal issue involving a trust is about administration. A trust might come up in a contract dispute, a real estate matter, or a family law case.
For those situations, other courts can hear the case too.
The superior court has concurrent jurisdiction with other courts of this state of other proceedings involving a trust.
A.R.S. § 14-10203(B)In other words, trust administration questions go to superior court. If a trust is part of a broader legal dispute, the case may be heard in whatever court covers that matter.
Knowing where to file saves time and avoids missteps. It also keeps trust disputes moving toward resolution.
