Power of Attorney in Arizona: Requirements, the Witness Rule, and How to Get One
An Arizona power of attorney needs a witness and a notary, and the witness can't be the agent's family. Here is what A.R.S. 14-5501 requires and how to set one up.

What to know
- An Arizona financial power of attorney must be signed by your parent, witnessed by one adult, and acknowledged before a notary (A.R.S. 14-5501(D)).
- The witness can't be the agent, the agent's spouse, the agent's children, or the notary.
- To keep working if your parent becomes incapacitated, it must contain durability wording, such as "This power of attorney is not affected by subsequent disability or incapacity of the principal or lapse of time."
- Arizona's financial power of attorney doesn't cover health care; Arizona uses a separate health care power of attorney for that.
- Retirement Checklist turns your parent's situation into a short, ordered plan, so the power of attorney sits in the right place among everything else.
A power of attorney in Arizona is valid when your parent signs it, one qualified adult witnesses it, and your parent acknowledges it before a notary, who completes a certificate under seal. Those requirements come from A.R.S. 14-5501. The witness rule focuses on the agent's side: it excludes the agent and the agent's spouse and children, not your parent's relatives.
What is a durable power of attorney in Arizona?
A durable power of attorney is, in the statute's words, "a written instrument by which a principal designates another person as the principal's agent." Your parent is the principal; the person they name is the agent, who makes financial decisions on their behalf.
"Durable" means it keeps working if your parent later becomes incapacitated. In Arizona that has to be written in. Under A.R.S. 14-5501(A) and (B), the document must contain words showing that intent, such as:
- "This power of attorney is not affected by subsequent disability or incapacity of the principal or lapse of time."
- "This power of attorney is effective on the disability or incapacity of the principal."
The first starts now and continues through incapacity; the second starts only on incapacity. Our guide to power of attorney for an elderly parent covers when to set one up.
What does Arizona require for a power of attorney to be valid?
Arizona requires four things under A.R.S. 14-5501(D): wording that shows intent and names the agent, your parent's signature, one qualified witness, and a notary's acknowledgment under seal.
| Requirement | What the statute says |
|---|---|
| Intent | Contain language that clearly shows your parent intends to create a power of attorney and clearly identifies the agent |
| Signature | Be signed or marked by your parent, or signed in their name by someone else in their conscious presence and at their direction |
| Witness | Be witnessed by a person other than the agent, the agent's spouse, the agent's children or the notary |
| Notary | Be acknowledged by your parent, with an affidavit of the witness, before a notary, evidenced by the notary's certificate under seal |
Both are needed: one witness and a notary. The witness swears that your parent signed willingly and signs "in the presence and hearing of the principal," and your parent states in the certificate that they are "of sound mind and under no constraint or undue influence."
Capacity matters. Under A.R.S. 14-5506, "A power of attorney executed by an adult who does not have capacity is invalid," and an agent who used intimidation or deception to get one can face prosecution and civil penalties.
One newer step: under A.R.S. 41-254, as amended by SB 1479 (Laws 2026, chapter 31), a notary must have the signer place their right thumbprint in the notary's journal when notarizing a power of attorney, with an exception for some remote notarizations. The Arizona Legislature gives September 12, 2026 as the general effective date for that session's laws.
Is there an official Arizona power of attorney form?
No. Arizona's power of attorney article, A.R.S. 14-5501 to 14-5507, doesn't contain a fill-in statutory form for a financial power of attorney. Its only "substantially the following form" language is the notary and witness certificate. The Arizona Attorney General's free Life Care Planning packets cover health care documents, not a financial power of attorney.
Some powers need to be granted expressly. Under A.R.S. 14-10602, an agent can exercise your parent's powers over a revocable trust only to the extent the trust or the power of attorney expressly authorizes it. And under Arizona's elder financial protection statute, A.R.S. 46-456, a person in a position of trust with a vulnerable adult "shall use the vulnerable adult's assets solely for the benefit of the vulnerable adult," unless, among other exceptions, the transaction is "specifically authorized in a valid durable power of attorney."
When does it take effect, and when does it end?
It takes effect when its wording says, and it ends at your parent's death. The wording sets the start: now, with the "not affected by subsequent disability" language, or on incapacity, with the "effective on the disability or incapacity" language.
At your parent's death, under A.R.S. 14-5504 an agent or other person who acts in good faith without knowing of the death is still protected. A court-appointed conservator doesn't end it automatically, but under A.R.S. 14-5503 the agent becomes accountable to the conservator, and the conservator "has the same power to revoke or amend the power of attorney that the principal would have." A power of attorney can also nominate a conservator or guardian for the court to consider.
Divorce is less clear-cut. Arizona's probate code says a divorce revokes a revocable nomination of a former spouse to serve as an "agent" in a governing instrument, unless the instrument or a court order says otherwise (A.R.S. 14-2804). Whether that reaches a particular power of attorney is a question for an attorney.
What does the agent have to do?
An Arizona agent dealing with a vulnerable adult's money must use it only for that adult's benefit, under A.R.S. 46-456; the power of attorney article itself, A.R.S. 14-5501 to 14-5507, has no list of agent duties. Under A.R.S. 46-456, an agent who misuses a vulnerable adult's assets can owe actual damages, costs and attorney fees, and a court may award up to two times the actual damages on top. Arizona also treats an agent under a durable power of attorney as a "fiduciary" for court purposes.
The statute's exception for transactions "specifically authorized in a valid durable power of attorney" means the document's wording decides whether an agent may benefit. Records of each transaction give the agent a way to show how the money was used. Our guide to protecting a parent from scams covers the warning signs any agent should know.
Do banks have to accept an Arizona power of attorney?
Not under Arizona's power of attorney statutes. The article, A.R.S. 14-5501 to 14-5507, doesn't contain a rule requiring a bank or other institution to accept one, or a deadline for doing so. What it does is protect people who deal with an agent in good faith: under A.R.S. 14-5506(C), they're "protected as if the agent properly exercised the agent's power." An agent can also sign an affidavit that they had no knowledge of revocation or death, which creates a rebuttable presumption that the power was still in effect (A.R.S. 14-5505).
Because the article sets no acceptance rule, the agent can ask your parent's bank ahead of time whether it will accept the document and what it wants to see.
How do you get a power of attorney for an elderly parent in Arizona?
Your parent makes it, signing in front of a qualified witness and a notary. The steps:
- Talk with your parent about who they'd want acting for them, and who should step in if that person can't.
- Choose a document, drafted by an attorney or from a reputable source, and check that it contains durability wording.
- Decide whether it should take effect now or only on incapacity.
- Line up a witness who isn't the agent, the agent's spouse or the agent's children, plus a notary.
- Your parent signs in front of both; the witness signs an affidavit, and the notary completes the certificate.
- Give the agent a copy, keep the original somewhere safe, and check with your parent's bank.
Timing is a legal limit: a power of attorney signed by an adult without capacity is invalid (A.R.S. 14-5506). If your parent no longer has capacity, the family may need a court process instead, described in conservatorship and guardianship. For a complicated situation, see what an elder law attorney does.
How do you revoke a power of attorney in Arizona?
In writing, according to court-published instructions; Arizona's power of attorney article doesn't prescribe a method. The Superior Court of Arizona in Maricopa County publishes a revocation packet, linked from the Attorney General's site, whose instructions say: "You may revoke a Power of Attorney at any time and for whatever reason you wish. You must do it in writing and give a copy of the Revocation form to any interested third party such as a bank or financial institution."
The same instructions add that "If your Power of Attorney was recorded for real estate purposes, the revocation must be recorded as well," and that "An incapacitated or incompetent principal cannot revoke a Durable Power of Attorney."
How much does a power of attorney cost in Arizona?
Arizona law sets no price for the document itself; the cost depends on who drafts it, because Arizona has no statutory financial power of attorney form. The notary's fee is the part the state controls. Under A.R.S. 41-316, the Secretary of State sets notary fees by rule, and a notary "shall not advertise or charge or receive a fee for performing a notarial act except as specifically authorized by rule."
Frequently asked questions
Does a power of attorney need to be notarized in Arizona?
Yes. Under A.R.S. 14-5501(D), an Arizona financial power of attorney must be acknowledged before a notary, with the notary's certificate under seal, and witnessed by one adult. The witness can't be the agent, the agent's spouse, the agent's children or the notary, so it takes two different people besides the agent.
Who can witness a power of attorney in Arizona?
Any adult other than the agent, the agent's spouse, the agent's children or the notary. The statute's exclusions focus on the agent's side, not your parent's. The witness signs a sworn statement, in your parent's presence and hearing, that your parent signed willingly, and the notary certifies the document under seal.
Where can I get an Arizona power of attorney form?
Arizona's power of attorney statutes don't include a fill-in financial form, and the Attorney General's free Life Care Planning packets cover health care documents only. An attorney can draft one. Whatever the source, check for durability wording and the witness and notary certificate required by A.R.S. 14-5501.
Can an Arizona financial power of attorney be used for medical decisions?
No. A.R.S. 14-5507 says the article doesn't establish authority under a durable power of attorney for health care decisions. Arizona uses a separate health care power of attorney, with its own signing rules: one adult witness or a notary. Our guide to Arizona advance directives explains it.
What if my elderly parent can no longer sign?
Someone else can sign your parent's name in their conscious presence and at their direction, but your parent must still have capacity: a power of attorney made by an adult without capacity is invalid. If your parent can no longer make that decision, a court guardianship or conservatorship may be the remaining route.
Is a power of attorney from another state valid in Arizona?
Yes, if it was valid where it was made. Under A.R.S. 14-5501(C), a power of attorney executed in another U.S. jurisdiction "is valid in this state if the power of attorney was validly executed in the jurisdiction in which it was created." A bank may still ask questions before accepting it.
Getting started
A power of attorney is time-sensitive, because it needs your parent's signature while they have capacity, and in Arizona it needs a witness, a notary and the right wording. The plan this site builds asks four questions, including which state your parents live in, and puts the handful of steps that matter most for your family in order. It's free and takes about 90 seconds.
