It's possible for spouses in any state to reach a fair property agreement during a divorce, although spouses in Maricopa County have a distinct advantage. Arizona is one of nine community property states, where court decisions about marital assets during divorce are based on an equal split. In other states, judges divide assets "fairly," which doesn't guarantee a 50-50 share.
Couples don't need a judge to tell them how to divide assets. Couples can create a pre- or postnuptial contract or agree to some other property division plan that a judge is likely to approve. The court gets pulled into disputes which can be contentious and expensive, especially during a high-asset divorce.
