Public Fiduciary Funds: How Estate Money Is Deposited and Invested

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

When a public fiduciary manages someone's estate or finances, all funds must be deposited in the county treasury or in insured financial institutions. The public fiduciary can also establish or continue an investment plan for a ward, but only with court approval and a surety bond if the court requires one.

Title 14, PROTECTION OF PERSONS UNDER DISABILITY AND THEIR PROPERTY

Where the Money Goes

Arizona law is specific about how a public fiduciary handles funds. Money cannot sit in an uninsured account or be managed informally. All funds must go into either the county treasury or an insured bank, credit union, or savings and loan association authorized to do business in the county.

All funds coming into the custody of the public fiduciary shall be deposited in the county treasury and disbursed at the direction of the public fiduciary or shall be deposited or invested in one or more insured banks or in one or more insured credit unions authorized to do business in the county.

A.R.S. § 14-5603(A)

If no insured financial institution operates within the county, the public fiduciary can deposit funds at any insured institution in the state. Withdrawals happen only at the direction of the public fiduciary, providing a layer of accountability.

Investment Plans Require Court Approval

The public fiduciary has the authority to establish or continue an investment plan for a ward. This is not a blank check. Three conditions must be met: the court must approve the plan, the plan must follow the same standard of care imposed on trustees under A.R.S. 14-10804 and 14-10806, and the court may require a surety bond to protect the assets.

The public fiduciary may establish or continue an estate or investment plan of the public fiduciary's ward if all of the following apply: 1. The public fiduciary receives the approval of the court for the plan. 2. The plan is consistent with the standard of care imposed on trustees in sections 14-10804 and 14-10806.

A.R.S. § 14-5603(B)

These safeguards exist because the public fiduciary is managing money on behalf of someone who cannot protect their own interests. A personal estate plan with a named trustee and clear investment instructions can achieve the same protections, with more flexibility and less court involvement.

A. All funds coming into the custody of the public fiduciary shall be deposited in the county treasury and disbursed at the direction of the public fiduciary or shall be deposited or invested in one or more insured banks or in one or more insured credit unions authorized to do business in the county or in one or more insured savings and loan associations authorized to do business in the county, and if there are no such insured banks, insured credit unions or insured savings and loan associations in the county, then the public fiduciary may deposit the funds in any insured bank or insured credit union or insured savings and loan association in the state. Money deposited with the county treasurer or deposited or invested with an insured bank, insured credit union or insured savings and loan association shall be withdrawn only at the direction of the public fiduciary. B. The public fiduciary may establish or continue an estate or investment plan of the public fiduciary's ward if all of the following apply: 1. The public fiduciary receives the approval of the court for the plan. 2. The plan is consistent with the standard of care imposed on trustees in sections 14-10804 and 14-10806. 3. The public fiduciary has obtained a surety bond in the amount of the assets within the plan if the court finds that a surety bond is necessary or desirable to protect the assets within the plan.

How do guardianship and conservatorship proceedings work in Arizona?

Both require filing with the Arizona Superior Court, medical evidence of incapacity, and a judge's approval. The process takes months and costs thousands. Powers of attorney accomplish the same goals without court involvement.

How do I choose the right trustee for my estate?

Choose a trustee based on competence, not convenience. Avoid naming all children as co-trustees, which creates gridlock. Pick your most capable child as primary and name a backup.
