Arizona power of attorney guide

Arizona Power of Attorney Guide

A financial power of attorney and a health-care power of attorney solve different problems. Start with the authority you want to grant, then use the matching Arizona rules and official form source.

Primary sources verified 2026-08-14. Statutes and government forms can change.

The Arizona financial rule

A durable financial power of attorney is a signed writing that identifies an agent and preserves or activates authority despite later incapacity. For an individual principal, Arizona requires a qualifying witness and notarized execution.

Choose the authority first

Financial and property

Use a financial POA

The document controls the financial, property, or business authority it actually grants. Durable language determines whether that authority continues through incapacity.

Medical decisions

Use a health-care POA

Arizona uses a separate document and execution statute for future health-care decisions.

Financial POA requirements

An adult principal must satisfy the execution path in A.R.S. §14-5501. The document’s label is not enough if the signing steps or durable language are missing.

  • The writing clearly shows an intent to create a power of attorney and clearly identifies the agent.
  • The principal signs or marks it, or directs another individual to sign in the principal’s conscious presence.
  • A qualifying witness signs; the witness cannot be the agent, the agent’s spouse, the agent’s child, or the notary.
  • The principal’s acknowledgment and the witness affidavit are completed before a notary public and evidenced by the notary’s certificate and seal.

The witness and notary do different jobs

A.R.S. §14-5501

Is witnessed by a person other than the agent, the agent’s spouse, the agent’s children or the notary public.

The same statute separately requires the principal’s acknowledgment and the witness’s affidavit before a notary. A notary alone does not replace the qualifying witness for this financial-document path.

Durable, regular, and springing authority

Durable now
Authority begins as stated and is not ended by later disability or incapacity.
Springing durable
The document states that authority becomes effective on disability or incapacity.
Regular
The document does not preserve authority through incapacity and may state a definite end date.

Source: A.R.S. §14-5501 and A.R.S. §14-5502.

Capacity is a signing-time issue

A.R.S. §14-5506

A power of attorney executed by an adult who does not have capacity is invalid. Capacity means understanding in a reasonable manner the nature and effect of executing and granting the power.

If capacity is already disputed, a blank form cannot resolve that question. The document also grants only the authority its language covers; it does not create health-care authority or replace a will, trust, beneficiary designation, or court appointment after death.

Official starting point

Use the current court packet

Frequently asked questions

What makes an Arizona financial power of attorney durable?

The writing must use language showing that the authority may continue despite later disability or incapacity, or become effective then. The current rule and sample language are in A.R.S. §14-5501.

Does an Arizona financial power of attorney need a witness and a notary?

For an individual principal, A.R.S. §14-5501 requires a qualifying witness and notarized acknowledgment and affidavit. The witness cannot be the agent, the agent’s spouse, the agent’s child, or the notary.

Can a financial power of attorney make medical decisions?

Not merely because it grants financial authority. Arizona’s health-care document follows a different statute, A.R.S. §36-3221, with its own execution and agent rules.

Can someone sign a power of attorney after losing capacity?

A document executed by an adult who lacks capacity is invalid under A.R.S. §14-5506. The statute defines capacity by whether the principal could reasonably understand the nature and effect of executing and granting the power.

Is an Arizona power of attorney filed with the court?

The court’s instructions say there is no need to file the completed general power of attorney with the court.
