Arizona: Adult Guardianship and Conservatorship Petition Requirements

Requirements one by one

Proceeding and state terminology

Arizona divides personal and financial authority. Guardianship under A.R.S. § 14-5303 concerns responsible decisions about the person. A protective proceeding under A.R.S. § 14-5401 concerns estate and financial affairs and may end in a conservator appointment or another protective order. A filer seeking both roles must use the requirements of both tracks.

Who may file and where

The adult or anyone interested in the adult's affairs or welfare may petition for guardianship. The adult, a parent, guardian or custodian, anyone interested in the estate or affairs, or someone adversely affected by poor management may seek financial protection. A.R.S. § 14-5302 permits guardianship where the adult resides or is present and in the county of a court-ordered institution; A.R.S. § 14-5403 makes financial venue follow residence or, for a nonresident, the county containing property.

What the petition must contain

Both petitions identify the adult, petitioner, proposed appointee and priority, existing fiduciary, nearest relative, property and benefits, need, powers of attorney, and trust interests. A.R.S. § 14-5404 supplies the financial checklist. The guardianship petition adds a prominent life-sustaining-treatment authority statement, identifies the requested type, and—when general authority is sought—must say alternatives were explored and why limited guardianship is inappropriate. The clinician and investigator reports follow after filing rather than being universal petition attachments.

Proof required for appointment

Guardianship requires clear and convincing proof of incapacity, necessity for demonstrated needs, and no sufficient less restrictive means. The A.R.S. § 14-5101 personal-capacity definition asks whether the adult can make or communicate responsible decisions concerning the person. Conservatorship also uses clear and convincing evidence, but its two findings concern effective management and the risk of waste/dissipation or need to obtain funds for support, care, and welfare.

Alternatives the court must address

A general-guardianship petition must document exploration of alternatives, and A.R.S. § 14-5304 bars appointment when demonstrated needs can be met by less restrictive means, expressly including appropriate technology. The financial provisions allow "another protective order" instead of a conservator, but A.R.S. §§ 14-5401, 14-5404, and 14-5407 do not state the guardianship track's separate requirement to prove that less restrictive means cannot meet the need.

Notice, service, and hearing timing

Under A.R.S. § 14-5309 and A.R.S. § 14-5405, the adult, spouse, and parents found in Arizona receive personal service at least 14 days before the hearing. Adult children, a serving guardian or conservator, the person with care or custody, a closest adult relative when needed, and anyone demanding notice also receive statutory notice. The adult cannot effectively waive notice without attending.

Counsel and hearing rights

If the adult lacks independent counsel, the court appoints counsel in both proceedings. Guardianship expressly gives the adult the rights to attend, hear or see the evidence, present evidence, cross-examine the clinician and investigator, request a closed hearing, and have a jury trial. A.R.S. § 14-5407 supplies parallel conservatorship participation and cross-examination rights and requires the initial hearing to state the jury right.

Financial proceedings also have a stronger appearance rule: unless the alleged basis is confinement, foreign detention, or disappearance, the adult must appear in person or virtually, or the record must contain evidence explaining inability or unwillingness to attend.

Medical evidence or court evaluator

Guardianship automatically brings two court appointments: an investigator and a physician, psychologist, or registered nurse examiner. The clinician must address diagnosis, functional impairments, decision communication, daily-living tasks, medications, prognosis, and a care or rehabilitation plan. Conservatorship automatically uses an investigator for the usual illness, disability, substance-use, or intoxication grounds, but a medical or psychological evaluation occurs only on an interested person's petition or the court's motion.

The shared investigator under A.R.S. § 14-5308 must have a law, nursing, or social-work background and no personal interest, interview the adult and proposed appointee, visit the current or proposed residence, and may examine relevant court, medical, and financial records.

Limits on the order

A.R.S. § 14-5304 directs the court to maximize self-reliance and permits a limited guardian with specified powers and time limits matched to the evidence. The financial court must make specific findings on the record and may choose another protective order rather than a conservator, but the cited financial sections do not impose an equivalent limited-conservatorship preference.

Temporary relief follows separate A.R.S. §§ 14-5310 and 14-5401.01. Without-notice appointment requires verified specific facts showing immediate and irreparable injury, loss, or damage; counsel is appointed unless already retained, prompt personal service and a hearing follow, and the no-notice order ordinarily expires within 30 days with a possible same-length good-cause extension unless counsel consents to longer.

What trips people up

The two tracks do not share identical less-restrictive language. It is accurate to say guardianship requires proof that needs cannot be met by lesser means. For conservatorship, the current statutes instead authorize a conservator or another protective order and require the financial incapacity and harm/support findings; they do not repeat the guardianship statute's technology-and-lesser-means element.

The medical evidence also differs. Guardianship always requires a court-appointed clinician unless another special statute applies. In an ordinary adult conservatorship, the investigator is mandatory for the listed disability grounds, while a separate medical or psychological evaluation is discretionary.

Common questions

Is a diagnosis alone enough for guardianship?

No. The clinician must connect diagnosis to functional impairments, daily tasks, and the ability to receive, evaluate, or communicate decisions, and the court must still find necessity and no sufficient less restrictive means by clear and convincing evidence.

Is counsel automatically appointed?

Yes, unless the adult already has independent counsel. That rule applies to both the ordinary guardianship and adult conservatorship proceedings.

Does the adult have to attend?

Guardianship gives the adult a right to be present. Conservatorship ordinarily requires appearance in person or virtually, with documented evidence required when the adult is unable or unwilling to attend; missing, confined, or foreign-detained cases are excepted.

Can an emergency appointment be made without notice?

Yes, but only on verified specific facts showing immediate and irreparable harm before opposition can be heard. The statutes then require appointed counsel, prompt service, a prompt hearing, and a short expiration period.
