The Priority Order for Guardian Appointments
When the court decides who should serve as guardian, it does not pick at random. Arizona law lays out a ranked list of people the court should consider. The incapacitated person's own preferences carry significant weight. If the person nominated someone in a durable power of attorney or healthcare power of attorney, that nomination is recognized in the priority order.
The court may consider the following persons for appointment as guardian in the following order: 1. A guardian or conservator of the person or a fiduciary appointed or recognized by the appropriate court of any jurisdiction in which the incapacitated person resides. 2. An individual or corporation nominated by the incapacitated person if the person has, in the opinion of the court, sufficient mental capacity to make an intelligent choice.
A.R.S. § 14-5311(B)After existing fiduciaries and the person's own nominee, the list moves to the agent named in a power of attorney, then spouse, adult children, parents, relatives with whom the person has lived for more than six months, and finally licensed fiduciaries and public fiduciaries.
Why a Durable Power of Attorney Matters Here
This statute is one of the strongest arguments for having a durable power of attorney in place. A person named as agent in a power of attorney ranks third on the priority list, behind only existing court-appointed fiduciaries and the incapacitated person's own nominee. Without that document, the court decides based on the statutory order.
The court can also pass over someone with higher priority for "good cause," which includes situations where a power of attorney is found to be invalid, where honoring it would not serve the person's best interests, or where professional fiduciary fees would strain the person's finances.
For good cause the court may pass over a person who has priority and appoint a person who has a lower priority or no priority.
A.R.S. § 14-5311(F)Families with young adults who have developmental disabilities should pay particular attention to subsection D. If a guardianship petition is filed within two years of the person's eighteenth birthday, the court generally appoints whoever had legal decision-making authority as the guardian, providing a smoother transition from parental rights to adult guardianship.
