The Arizona appellate courts recently issued two important decisions involving insurance coverage and bad faith.  These decisions will impact the Arizona insurance industry and are discussed below.

Arizona Plaintiff Must Prove She Would Have Prevailed in Underlying Case to Recover in Legal Malpractice Claim

A recent decision in Division One of the Court of Appeals held plaintiff must prove she would have prevailed in the underlying claim as an essential element of a legal malpractice claim.[i] In Bellemare v.

Claims Magazine – August 2020

In March 2020, the United States came to a screeching halt. Schools closed, businesses shut down and the national economy saw its largest decline in more than a decade.
