How the Trigger Works
The document itself defines the trigger. A typical clause requires written certification by one or two licensed physicians that the principal is no longer able to manage their own affairs. Until that certification exists, the agent has no authority to act.
Why Most Arizona Attorneys Prefer Immediate POAs
Springing POAs sound appealing for privacy, but they create real-world problems. Banks, brokerages, and title companies routinely refuse to act on a springing POA without seeing the physician certification. Getting that certification takes time and may require court intervention if the doctor will not sign. An immediate durable POA, paired with a trusted agent and clear instructions, is usually faster and less risky.
Arizona Durable POA Statute
Arizona's durable power of attorney statute is A.R.S. 14-5501, which sets the formal requirements for both immediate and springing POAs.
