Someone has to be able to reach your accounts, pay the bills, manage the rental, and talk to the bank if you are ever laid up for months. Without a durable financial power of attorney, the answer in Arizona is: nobody, until a court appoints a conservator. That process is public, slow, and expensive, and your family sits through it while the mortgage is due. One properly signed document prevents all of it.
What "durable" means
An ordinary power of attorney can die exactly when you need it - authority that ends at incapacity is useless for incapacity planning. A durable one keeps working. Arizona asks for explicit words, in substance: "This power of attorney is not affected by subsequent disability or incapacity of the principal or lapse of time." You can also make it "springing," so it only takes effect if you become incapacitated.
Arizona's signing rules are stricter than you expect
The financial POA has the toughest execution requirements of any Arizona planning document:
- Signed by you (or at your direction, in your conscious presence).
- Witnessed AND notarized - both. The health care documents need one or the other; this one needs both.
- The witness is restricted: the witness cannot be the agent, the agent's spouse, the agent's children or the notary.
- The statute prescribes the affidavit language the notary certifies - this is why the free generic internet form so often fails at the bank.
The timing rule families learn too late
a power of attorney executed by an adult who does not have capacity is invalid (A.R.S. § 14-5506). In plain terms: this document can only be signed while you are well. After a dementia diagnosis progresses, after the stroke, it is too late - the only remaining route is conservatorship court. Signing early costs nothing; signing late is not possible.
Choosing your agent
This person can move money, so choose with open eyes. Arizona law punishes agents who abuse the role, but the better protection is a trustworthy agent, a named backup, and a family that knows the document exists. If no one fits, a licensed fiduciary can serve - that is a real profession in Arizona, and it exists for exactly this.
Good to know
Under the statute, a power of attorney validly executed in another U.S. jurisdiction is valid in Arizona. And every power of attorney ends at death - at that moment your will, trust, and beneficiary designations take over, which is why this document is one piece of a set rather than a plan by itself.
