Child support is one of the most common issues that comes up during a divorce involving children in California. It also happens to be one of the most misunderstood. Parents on both sides often have questions about things like how the amount is determined, whether it can change over time, and what happens if payments are not made.
Continue reading for the answers to five of the most important questions about child support under California law. There is too much at stake to enter a situation like this uninformed about your rights.
1. How Is Child Support Calculated in California?
California uses a statewide formula to calculate child support. The formula is set out in Family Code Section 4055 and takes several factors into account. The two biggest factors are each parent’s income and the time each parent spends with the child.
Beyond those primary factors, the court also looks at:
- Tax filing status and deductions
- Health insurance costs for the child
- Childcare expenses
- Whether either parent supports children from another relationship
The court enters all this information into a certified guideline calculator to determine a presumptive support amount. Judges are required to follow this formula in most cases, though they can deviate from it in rare situations where the standard amount would be unjust.
2. Can Child Support Be Modified After It Is Ordered?
Yes. Child support orders in California are not set in stone. Either parent can request a modification if there has been a significant change in circumstances since the original order was put in place.
Common reasons for seeking a modification include a significant change in income and new childcare expenses, though there are many potential grounds a court may accept based on the facts of the case.
3. What Happens if a Parent Stops Paying Child Support?
California takes child support enforcement seriously. If a parent falls behind on payments, the state has several tools it can use to collect, including:
- Garnishing wages directly from the parent’s paycheck
- Intercepting state and federal tax refunds
- Levying bank accounts
- Holding the nonpaying parent in contempt of court, which can lead to fines and jail time
- Suspending the parent’s driver’s license
Recent changes to the law now protect lower-income parents from license suspension in certain situations, but the other enforcement methods remain fully in play.
4. Does Custody Affect How Much Child Support Is Paid?
Absolutely. The amount of time each parent spends with the child is a major factor in the support calculation. In general, the parent who has the child less often will pay support to the parent who has the child more.
Even in cases where custody is split equally, however, child support may still be ordered if there is a gap between the parents’ incomes. The formula is designed to make sure the child has a similar standard of living in both households, so income differences between the parents will almost always play a role.
5. Does Child Support Cover Everything a Child Needs?
The base child support amount is intended to cover day-to-day living expenses, such as food, clothing, and housing. However, certain costs fall outside that base amount and may be divided separately between the parents.
These “add-on” expenses can include:
- Childcare costs related to employment
- Uninsured medical and dental expenses
- Educational needs
- Travel costs for visitation
Under recent changes to California law via Senate Bill 343, these add-on expenses are now divided based on each parent’s share of the combined income, which is intended to make the split more fair.
