Child support is one of the most common sources of confusion in California family law cases. A lot of parents going through a separation or divorce want to know the same two things: how much they’ll owe (or receive) and who is actually responsible for paying. The answers depend on several factors specific to your situation, but the state does use a standard formula to maintain consistency.
Under California law, both parents share a legal obligation to financially support their children. This applies regardless of whether the parents were ever married. Here’s a closer look at how the process works and what the court considers.
Who Is Required to Pay Child Support?
It’s a common misconception that only fathers pay child support in California. In reality, either parent can be ordered to pay. The determining factors are income and custody time, not gender.
In most cases, the parent who earns more and spends less time with the child will be the one making payments. If one parent has primary physical custody, the other parent typically pays support to help cover the child’s day-to-day living expenses. However, in situations where both parents share custody relatively equally and earn similar incomes, the support obligation may be minimal.
The law assumes that the custodial parent is already contributing their share by directly paying for things like housing, food, and clothing. Child support from the other parent is meant to balance out that financial responsibility so the child benefits from the standard of living of both households.
What Factors Go Into the Calculation?
California uses a statewide guideline formula laid out in Family Code §4055 to determine child support amounts.
Although the formula is complex, the primary factors include:
- Each parent’s net monthly disposable income (from all sources, including wages, bonuses, rental income, and investments)
- The percentage of time each parent has physical custody of the child
- The number of children covered by the order
- Tax filing status and available deductions
- Health insurance premiums paid for the child
- Mandatory payroll deductions like union dues or retirement contributions
- Childcare costs related to employment or education
The guideline amount produced by the formula is presumed to be the correct amount per Family Code §4057(a). That means the judge is generally required to order it unless there’s a compelling reason to do otherwise.
When the Court Can Adjust the Guideline Amount
While the formula drives most child support orders, there are limited situations where a judge can deviate from the guideline. For example, if one parent has an extraordinarily high income, the court may determine that the formula amount exceeds the child’s actual needs.
Parents may also agree to a different support amount, but the agreement must still be approved by a judge. In addition, either parent can request a modification down the road if there’s been a material change in circumstances, such as a significant increase or decrease in income or a shift in the custody arrangement.
