Understanding Child Support Calculator in Arizona

Arizona is a community property state. Marital assets acquired during the marriage are presumed to belong equally to both spouses. In most cases, the court will divide community property 50/50.

The median cost of an uncontested divorce in Arizona is approximately $9,000. Contested divorces involving significant financial disputes average $40,000. These figures include attorney fees, filing fees ($280–$350), and related costs.

Under A.R.S. §25-318, Arizona courts consider the standard of living established during the marriage, each spouse’s income and earning potential, the duration of the marriage, and each party’s contributions — including homemaking and child-rearing.
