Understanding Child Support Calculator in California

California 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 California is approximately $14,500. Contested divorces involving significant financial disputes average $62,000. These figures include attorney fees, filing fees ($435–$450), and related costs.

Under Cal. Fam. Code §2310, California 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.
