AZ SB1226

Amends Arizona law to require peace officers to evaluate each party's alleged acts of domestic violence and determine which party, if any, is the predominant aggressor before arresting both parties.

Establishes factors for officers to consider when identifying the predominant aggressor, including previous domestic violence acts, injuries suffered, coercive control behaviors, plausibility of statements, and witness statements.

Defines "coercive control" as a pattern of controlling and psychologically destructive behaviors including demeaning language, restricting social activities or financial access, threats of suicide or harm to others, threats involving children or pets, and monitoring communications.

Allows officers to choose not to arrest the party determined to not be the predominant aggressor, rather than arresting both parties in domestic violence incidents.

Maintains existing provisions on firearm seizure, victim notification, court procedures for firearm retention, and requirements to inform victims of protection options and resources.
