What Makes a Power of Attorney Durable in Arizona?
A Power of Attorney can be an important part of planning for the future, but not every Power of Attorney is the same.
One of the most important distinctions is whether the document is durable.
A Durable Power of Attorney is designed to continue providing authority even if the person who created it later becomes incapacitated or unable to make decisions for themselves. Arizona law has specific requirements for creating a durable power of attorney, including requirements concerning the language of the document, the principal, the witness, and notarization.
If you're considering a Power of Attorney in Arizona, here's what to know.
What Is a Durable Power of Attorney?
A Durable Power of Attorney is a written document in which one person—the principal—designates another person as their agent to act on their behalf.
What makes it durable is language demonstrating that the authority can continue even if the principal subsequently becomes disabled or incapacitated.
Arizona law specifically provides that a durable power of attorney must demonstrate the principal's intent that the authority may be exercised:
If the principal later becomes disabled or incapacitated; and
Regardless of how much time has passed, unless the document establishes a definite termination date.
The statute provides examples of language that can demonstrate this intent, including language stating that the Power of Attorney is not affected by the principal's subsequent disability or incapacity.
In other words, “durable” isn't simply a label on the document. The document must contain language establishing the principal's intent for the authority to continue under those circumstances.
Why Does Durability Matter?
Consider a situation where someone creates a Power of Attorney and later becomes unable to manage their financial affairs.
If the Power of Attorney was properly created as a durable Power of Attorney, the agent's authority can continue during the principal's disability or incapacity.
Arizona law provides that acts performed by an agent pursuant to a durable Power of Attorney during the principal's disability or incapacity have the same effect as if the principal were not incapacitated.
That's one reason these documents can be an important part of planning ahead.
The Timing Matters
There is another important consideration: capacity at the time the Power of Attorney is created.
Arizona law states that a Power of Attorney executed by an adult who does not have capacity is invalid. The law defines capacity in this context as being capable, at the time the document is executed, of understanding in a reasonable manner the nature and effect of creating and granting the Power of Attorney.
That means a Power of Attorney generally needs to be addressed before a person has lost the capacity required to execute one.
This is one of the reasons planning ahead can be so important.
Arizona Has Specific Signing Requirements
Arizona law establishes specific requirements for creating a financial Power of Attorney.
For an individual creating a Power of Attorney, the document must:
Clearly indicate the principal's intent to create a Power of Attorney.
Identify the agent.
Be signed or marked by the principal, or signed at the principal's direction in the principal's conscious presence.
Be witnessed by a qualified witness.
Be acknowledged by the principal before a notary public.
Include the required witness affidavit before the notary.
The witness also cannot simply be anyone.
Arizona law prohibits the agent, the agent's spouse, the agent's children, or the notary public from serving as the required witness.
Because of these requirements, it's a good idea to understand what will be needed before arriving at a notarization appointment.
What Does the Notary Do?
This is an important distinction:
A notary does not create or approve your Power of Attorney.
The document itself should already be prepared before the notarization appointment.
The notary's role is to perform the notarial act required for the document and complete the appropriate notarial certificate and journal entry.
A notary also cannot determine whether a particular Power of Attorney is appropriate for your situation, explain the legal consequences of the powers granted, or advise you about which powers you should give to an agent.
If you need help deciding what type of Power of Attorney you need or what language should be included, an attorney can provide legal advice.
Don't Forget the Witness
One detail that can easily catch people off guard is the witness requirement.
Arizona's financial Power of Attorney statute requires a witness in addition to the notary. The witness signs an affidavit before the notary confirming, among other things, that the principal signed willingly and appeared to meet the statutory requirements.
The Maricopa County Superior Court's Power of Attorney Resource Guide also recommends bringing a willing witness to the appointment rather than assuming the notary will provide one.

What About Health Care Powers of Attorney?
A financial Durable Power of Attorney is not the same thing as a Health Care Power of Attorney.
Arizona has separate statutes governing health care powers of attorney. A health care Power of Attorney allows an individual to designate an agent to make health care decisions on their behalf under the circumstances established by the document and Arizona law.
There are also separate Arizona laws addressing mental health care powers of attorney.
So if someone tells you they need “a Power of Attorney,” that's not necessarily enough information to determine which document they actually need.
A New Notarization Requirement: SB 1479
Arizona has also recently added an additional requirement that affects notarizations involving Powers of Attorney.
Senate Bill 1479 became effective September 12, 2026.
Under the new law, Arizona Notaries Public are required to obtain the signer's right thumbprint in the notary journal when notarizing certain documents, including Powers of Attorney. The requirement also applies to certain deeds and other documents affecting real property.
The fingerprint is placed in the notary's journal—not on the Power of Attorney itself.
There are provisions addressing situations where a right thumbprint isn't available, so the appropriate procedure may depend on the circumstances.
If you're signing a Power of Attorney in Arizona, don't be surprised if the notarization process now includes a fingerprint in the notary journal.
What Should You Bring to a Power of Attorney Notarization?
If your Power of Attorney has already been prepared and you're ready to have it notarized, planning ahead can make the appointment much easier.
Depending on the document and circumstances, you may need:
✓ The completed Power of Attorney
✓ Acceptable identification
✓ The required witness
✓ The principal who will be signing
✓ Any additional documentation requested by the notary
And because Arizona's SB 1479 requirements are now in effect, a Power of Attorney notarization may also require the principal's right thumbprint in the notary journal.
The Nevermore Bottom Line
A Durable Power of Attorney is about planning before a crisis happens.
The goal is to establish who can act on your behalf and create the legal authority necessary for that person to do so if circumstances change.
But the document needs to be properly prepared and executed. Arizona has specific requirements concerning the document, the principal, the witness, and the notarial act.
And with SB 1479 now in effect, Arizona's notarization process includes an additional journal requirement for Powers of Attorney.
Have a Power of Attorney already prepared and need the notarization completed? Nevermore Notary can provide the notarial service required for your document.
