Arizona Advance Directive for Single People: Planning Without a Spouse or Family

The Default Surrogate System Works Against You

When a married person becomes incapacitated without an advance directive, Arizona's statutory surrogate hierarchy (A.R.S. § 36-3231) kicks in: spouse first, then adult children, then parents, then siblings. Imperfect, but functional.

When a single person without nearby family becomes incapacitated without advance directives, that hierarchy either stalls entirely (no one in the priority list is available or willing) or defaults to distant relatives who barely know your values. Worst case: a court appoints a guardian — a stranger making your medical decisions based on their own judgment, not yours.

This makes advance directive planning more urgent for single people, not less. You don't have a default safety net. You need to build one deliberately.

Choosing an Agent Without a Spouse

Your Healthcare POA agent doesn't have to be a family member. Under A.R.S. § 36-3221, any adult of sound mind can serve (with narrow exceptions for suspended fiduciaries). Common choices for single adults:

A trusted friend. Someone who knows your values, lives within reasonable proximity (or can be reached by phone at all hours), and won't be emotionally paralyzed by hard decisions. The strength of this choice depends entirely on the friend's reliability and willingness to advocate against medical professionals if needed.

A sibling or parent who knows you well — even if they live out of state. Distance matters less than values alignment. Hospital decisions happen by phone as often as in person.

A professional patient advocate. In Maricopa County, private patient advocates and care managers serve as healthcare agents for a fee. This works if you genuinely have no one else, but understand that a paid professional lacks the personal relationship that helps with nuanced "quality of life" decisions.

Regardless of who you choose, name at least two alternates. Single people have no built-in backup if their primary agent is unreachable during a crisis.

The Witness Problem for Singles Living Alone

Arizona's witness exclusion rules create a specific friction point for single people. If you use only one witness (instead of a notary), that witness cannot be related to you, cannot inherit from you, cannot be your named agent, and cannot be your healthcare provider.

For someone who lives alone with a small social circle, finding an eligible witness can feel absurd. Practical solutions:

• Use a notary public instead of a witness. Notaries don't have the relationship restrictions that witnesses do. Arizona caps the fee at $10 per notarial act. Mobile notaries come to you.
• Remote Online Notarization (RON) is legal in Arizona for healthcare directives. You can execute your advance directive via video conference with a commissioned remote notary from your own home.

Veterans: VA Advance Directives vs. Arizona State Forms

Arizona veterans face a specific jurisdictional question: the VA healthcare system has its own advance directive form (VA Form 10-0137), and VA facilities will honor it within the VA system. But:

• VA advance directives may not be recognized at non-VA hospitals and emergency rooms. If you're taken to a Banner or HonorHealth ER, their legal team reviews Arizona state-format documents, not VA forms.
• Arizona state advance directives are honored at VA facilities in Arizona, as long as they were validly executed under state law.

Best practice for veterans: Execute Arizona state-format documents (HCPOA + Living Will + Mental Health POA) and submit them to the AzHDR registry. Separately complete VA Form 10-0137 for your VA medical record. Belt and suspenders — you're covered regardless of which facility you land in.

Veterans receiving care through the Phoenix VA Health Care System should also discuss their advance care plans with their VA primary care provider, who can enter directives directly into the VA electronic medical record.

The Registration Safety Net

For single people especially, registering your advance directives with the Arizona Healthcare Directives Registry (AzHDR) through Contexture isn't optional — it's critical. If you're found unconscious with no family member available to hand documents to the ER team, registered directives can be pulled up electronically by hospital staff. Carry the AzHDR wallet card so emergency responders know to check.

Building Your Support Network Deliberately

Beyond the legal documents, single people need an operational plan:

• Tell your agent and alternates where your documents are stored. If they don't know you have an advance directive, the document doesn't help.
• Give copies to your primary care physician and any specialist you see regularly.
• Keep the AzHDR wallet card in your physical wallet — not a desk drawer.
• Review annually. Relationships change faster when you're single. Make sure your named agent is still willing, available, and aligned with your values.
