When a minor or an incapacitated adult cannot make decisions for themselves, an Arizona court can appoint a guardian (for the person) or conservator (for finances). These are serious responsibilities the court supervises.
What Arizona law says
A.R.S. § 14-5301 — Guardianship of an incapacitated adult who cannot meet essential needs for health, safety, or self-care.
A.R.S. § 14-5201 — Guardianship of a minor when a parent is unavailable or unable to care for the child.
A.R.S. § 14-5401 — Conservatorship, which gives an appointed person authority to manage another’s financial affairs.
