How Insurance Bad Faith Is Proven in Arizona
Because Arizona asks whether the insurer had a reasonable basis and whether it knew it did not, the evidence is about process — what was investigated, what was ignored, and what the file shows the insurer understood.
The claim file and log notes
The contemporaneous record of the insurer's decision-making. In Arizona it bears directly on the Zilisch elements: whether a reasonable basis existed, and whether the insurer knew or recklessly disregarded its absence.
Adequacy of the investigation
Arizona requires an adequate investigation as part of good-faith handling. What the insurer failed to look at is often more probative than what it found.
Needless adversarial hoops
Repeated document demands for material already provided, examinations under oath used as pressure, and moving requirements are all recognized in Arizona as the kind of conduct the equal-consideration standard exists to prevent.
The regulatory standards
Arizona's claims-handling regulations describe what proper handling looks like. They are not a private cause of action, but they are a benchmark.
Common questions
What evidence matters most in an Arizona bad-faith case?
The claim file and the adjuster's notes, because Arizona's standard is about whether a reasonable basis existed and whether the insurer knew it did not.
They keep asking for documents I already sent.
That pattern is directly relevant in Arizona, which recognizes needless adversarial hoops as a form of unreasonable handling.
