Arizona Guardianship and Conservatorship: A Family’s Guide

When an adult can no longer make safe decisions — because of dementia, a brain injury, a serious mental illness, or a developmental disability — and no one holds legal authority to step in, an Arizona family often faces a hard choice: ask the court to appoint a guardian or conservator. It’s one of the few areas of estate and family law that begins as a medical and emotional crisis and ends in a courtroom. The good news is that guardianship is not always necessary, and it isn’t always the right answer. This guide explains the difference between a guardian and a conservator, when each is needed, how the Arizona court process works, and the less-restrictive alternatives that can sometimes avoid the whole thing.

Guardian, conservator, or power of attorney?

These three terms get used interchangeably, but they mean different things — and the difference decides whether you even need a court. The short version: a power of attorney is something a person sets up in advance, while they still have capacity; guardianship and conservatorship are what a court imposes after capacity is already gone and no advance plan exists.

This is why elder law attorneys push so hard for powers of attorney before they’re needed: a durable financial power of attorney and a healthcare power of attorney can do most of what a guardianship and conservatorship do, without a court, without the cost, and without the loss of independence. Guardianship exists for the situations where that planning never happened — or where someone never had the capacity to do it. For the full breakdown of the lighter-touch options, see our guide to alternatives to guardianship in Arizona.

Guardian vs. conservator: the core distinction

Arizona splits the authority to make decisions for an incapacitated adult into two separate roles, governed by different statutes and obtained through different (though often combined) petitions.

• A guardian is responsible for the person — health care, medical treatment, living arrangements, and daily-life decisions. The adult is called an “incapacitated person,” and guardianship is governed by A.R.S. §§ 14-5301 to 14-5317.
• A conservator is responsible for the property — income, assets, bills, and financial transactions. The adult is called a “protected person,” and conservatorship is governed by A.R.S. §§ 14-5401 to 14-5433.

A person may need a guardian, a conservator, or both. An aging parent with dementia who owns a home and investment accounts often needs both — a guardian to authorize memory-care placement and medical treatment, and a conservator to manage and protect the finances. An adult child with a developmental disability who receives benefits but owns little property might need only a guardian. Someone who can handle daily life but received a large settlement they can’t manage might need only a conservator. For a deeper side-by-side, see guardianship vs. conservatorship in Arizona.

What a guardian does

Under A.R.S. §§ 14-5301 and following, a guardian’s authority generally includes consenting to or refusing medical treatment, deciding where the person lives (including placement in assisted living, memory care, or skilled nursing), making decisions about care and services, and accessing the records needed to make informed choices. Guardianship does not automatically include authority over inpatient mental health treatment — that requires a separate, heightened showing and specific court authorization. An Arizona guardian files an annual report to the court on the person’s welfare.

What a conservator does

Under A.R.S. §§ 14-5401 and following, a conservator collects and protects income and assets, pays bills and debts, manages investments prudently, files an inventory of the estate, and files detailed annual accountings of everything received and spent. The court often requires a bond. To appoint a conservator for an adult, the court must find by clear and convincing evidence that the person cannot manage their financial affairs and that their property will be wasted or dissipated without protection.

When guardianship or conservatorship becomes necessary

Courts in Arizona don’t grant these powers lightly, because they take away a person’s legal right to make their own decisions. A judge generally needs to be satisfied, with supporting medical evidence, that the adult is genuinely unable to manage and that no less-restrictive option will work. Common situations include:

• A parent with advancing dementia who is making unsafe decisions and signed no powers of attorney.
• An adult who suffered a sudden injury or stroke and cannot manage care or finances, with no plan in place.
• A young adult with a significant developmental or intellectual disability reaching age 18, when parents’ automatic authority ends.
• A vulnerable adult being financially exploited, where a conservator is needed to protect assets.

Guardianship covers the person; conservatorship covers the property. Many cases need both, and one person often serves in both roles. The proceedings are handled in Arizona’s probate court — in Maricopa County, through the Superior Court Probate Department. The governing statutes are in Title 14 of the Arizona Revised Statutes.

How the Arizona court process works

The steps vary with the facts, but a typical guardianship/conservatorship case moves through a recognizable sequence:

1. Petition. The proposed guardian or conservator files a petition with the Superior Court in the county where the person lives, explaining why it’s needed and who should serve.
2. Medical evidence. Under A.R.S. § 14-5303, a physician’s, registered nurse’s, or psychologist’s written report on the person’s capacity must be filed with the court before the hearing.
3. Appointed advocates. The court appoints an attorney to represent the person who is the subject of the petition, and may appoint an investigator or court visitor to interview the parties and report back.
4. Notice. The proposed ward must be personally served, and close family members must be formally notified and given the right to object.
5. Hearing. A judge decides whether the legal standard is met and, if so, what powers to grant — sometimes limited rather than full.
6. Training. A non-professional guardian or conservator must complete a court-approved training program before Letters are issued.
7. Ongoing duties. A conservator files an inventory and regular accountings; a guardian files periodic welfare reports. The court keeps oversight for the life of the case.

It is not a one-and-done filing. Both roles carry continuing responsibilities and accountability to the court, which is part of why they’re treated as a last resort rather than a convenience. For the complete walkthrough, see our step-by-step guide to becoming a guardian of an adult in Arizona.

Limited vs. full guardianship

Arizona favors the least-restrictive arrangement that still protects the person. A limited guardianship grants authority over only specific areas — for example, medical decisions only — while the person keeps the right to make decisions in every other part of their life. A full (general) guardianship grants complete authority over the person’s personal and medical affairs and is reserved for situations where the person cannot make informed decisions across the board. The same limited-vs-full distinction applies to conservatorship: it can be limited to a single transaction (selling a house, settling a lawsuit) or a full ongoing management of the entire estate. Even rights many assume are automatically lost — like the right to vote — can sometimes be retained in a limited guardianship if the petition requests it and the court agrees.

Less-restrictive alternatives worth considering first

Because guardianship removes rights, the law favors lighter-touch options when they’ll do the job. Depending on the situation, alternatives can include:

• Durable and healthcare powers of attorney — if the person still has capacity to sign them. See our guide to the Arizona healthcare power of attorney and living will.
• A representative payee for managing Social Security or other benefit income.
• A revocable living trust with a successor trustee ready to step in — see Arizona revocable living trusts.
• Supported decision-making arrangements, where a person keeps their rights but gets formal help making choices.
• A special needs trust to manage assets for a disabled person without a conservatorship — see Arizona special needs trusts.

For adults with developmental or intellectual disabilities, Arizona’s Division of Developmental Disabilities (within the Arizona Department of Economic Security) is also part of the support picture. A good attorney will tell you honestly when one of these is enough and a full guardianship would be overkill. For the complete rundown, see alternatives to guardianship in Arizona.

When guardianship is contested

Some of the most painful cases are the ones where the family doesn’t agree — siblings who each believe they should serve, or who disagree about whether a parent needs help at all. These cases turn into litigation, with competing petitions, medical disputes, and hearings. They’re emotionally and financially costly, and they’re exactly the situation where experienced counsel matters most — both to protect the vulnerable adult and to keep the conflict from doing lasting damage to the family. If you anticipate a family fight over a parent’s care or finances, getting an attorney involved early is the best protection against a dispute spiraling.

Frequently asked questions about Arizona guardianship and conservatorship

What’s the difference between a guardian and a conservator?

A guardian makes personal and medical decisions for the person; a conservator manages their money and property. Many cases involve both, and the same individual frequently serves in both roles.

Can we avoid guardianship if my parent already has dementia?

Sometimes. If they still have enough capacity to understand and sign powers of attorney, those can avoid a guardianship. Capacity isn’t all-or-nothing, so this is worth assessing quickly — the window can close as a condition progresses.

How long does a guardianship case take in Arizona?

An uncontested case can often be completed in a couple of months from filing to appointment; contested cases take much longer. Emergency or temporary appointments are available when someone is in immediate danger.

Do guardians and conservators get paid?

They can be reimbursed for reasonable expenses, and in some cases compensated, especially professional fiduciaries. Conservators must account to the court for how estate money is spent.

What happens when a disabled child turns 18?

Parents’ automatic legal authority ends at 18, even for a child with a significant disability. Families often plan ahead for a guardianship or a less-restrictive alternative timed to that birthday, paired with a special needs trust for finances.

Do I need a lawyer for a guardianship?

Not legally for a simple, uncontested case — the courts publish self-service forms. But guardianship removes a person’s legal rights, requires medical evidence and a hearing, and carries ongoing reporting duties with personal responsibility. Any family disagreement makes it adversarial fast. Most families use an attorney to navigate the petition, the hearing, and the ongoing obligations.
