How to Enforce Child Support in California
If you're not receiving the child support you're owed, you're not just dealing with a financial problem. You're dealing with uncertainty, frustration, and the weight of trying to meet your child's needs on your own. The good news: California has some of the strongest child support enforcement tools in the country, and you don't have to chase payments alone. This guide walks you through how to establish an order, how courts calculate what's owed, and exactly what enforcement options are available when a parent stops paying.
In California, child support is enforced primarily through automatic wage garnishment, which courts build into every support order from the start. If payments stop, the California Department of Child Support Services (DCSS) can also intercept tax refunds, suspend driver's and professional licenses, freeze bank accounts, and file property liens. Persistent nonpayment can result in contempt of court charges and, in some cases, jail time. Free enforcement help is available through your local child support agency, but you must have a court order in place first.
How to establish a child support order in California
Enforcement only works once a formal court order exists. If you don't have one yet, getting one is the first priority. In California, there are two paths depending on where you are in the divorce or separation process.
If you already have an open family court case
Divorce cases and child support cases both originate in California's Family Court system. If your divorce is already filed but child support hasn't been addressed, you can request a support order through the same courthouse handling your divorce.
- 1
- 2
File with the court. Bring two copies to the courthouse processing your divorce. The clerk will stamp your forms and give you a hearing date.
- 3
Serve the other parent. Have someone 18 or older (not you) deliver copies to your co-parent, along with a blank Responsive Declaration to Request for Order (FL-320) and a blank Income and Expense Declaration (FL-150).
- 4
File proof of service. Ask the person who served the forms to complete a Proof of Personal Service (FL-330). Make two copies and file one with the court.
- 5
Attend your hearing. The judge will review income information from both parties and issue a support order.
If you haven't filed for divorce yet
You don't need to wait until your divorce is finalized to get a child support order. If no family court case exists, you can start one. Begin by filing a Petition (FL-100), a Summons (FL-110), and a Declaration under the Uniform Child Custody Jurisdiction and Enforcement Act (FL-105) at a courthouse that accepts divorce filings. Filing fees typically run $435 to $450, though fee waivers are available for those who qualify. A family law facilitator at your local courthouse can walk you through the process at no charge.
Once filed, you'll serve your co-parent with copies of the stamped forms plus a blank FL-320 and FL-150, and file your proof of service as described above. From there, the court sets a hearing date and can issue a temporary support order while the larger case proceeds.
How courts calculate the child support amount
California uses a statewide guideline formula to calculate child support. The formula weighs each parent's net monthly disposable income, the percentage of time each parent spends with the child, the number of children, and certain add-on expenses. Courts use software programs to run the calculation, and the result is treated as the presumed correct amount.
Add-ons are mandatory extras on top of the base support amount. They cover things like uninsured medical costs, childcare expenses tied to employment or education, and certain educational needs. Both parents share these costs proportionate to their net incomes under the updated guidelines that took effect in September 2024.
The custodial parent (the parent with whom the child spends more time) typically receives support from the other parent. Generally, the more parenting time the paying parent has, the lower their monthly payment, because they're covering more of the child's direct living expenses during their time.

California's child support guidelines underwent the most significant overhaul in decades when Senate Bill 343 took effect on September 1, 2024. If your support order was established before that date, it reflects the old rules. Here's what changed and why it matters.
- Add-on expenses are now split by income, not 50/50. Before SB 343, costs like uninsured medical bills and childcare were typically divided equally between parents. Under the new rules, these costs are apportioned based on each parent's net income. A parent earning significantly more will generally bear a larger share.
- A new low-middle income bracket was created. Parents earning between roughly $2,000 and $4,000 per month now fall into a tiered bracket that can trigger a rebuttable presumption for adjusted support amounts, intended to prevent undue hardship on lower earners.
- The low-income adjustment threshold was updated. The threshold is now tied to full-time minimum wage in California (calculated annually), rather than the Consumer Price Index. This means the baseline shifts with minimum wage increases each year.
- Incarceration can no longer be treated as voluntary unemployment. Courts must now make individualized findings about a parent's ability to pay rather than automatically imputing income to an incarcerated parent.
- Electronic Income Withholding Orders (E-IWOs) are now standard. The shift to automated withholding orders makes employer compliance faster and more consistent, reducing payment delays for custodial parents.
How courts enforce child support payments
California judges include an Income Withholding Order (sometimes called an earnings assignment order) with virtually every child support order. This instructs the paying parent's employer to deduct support directly from each paycheck before it's issued and forward the funds to the State Disbursement Unit, which then sends them to the custodial parent. Employers are legally required to comply, and most do so immediately upon receiving the order.
For parents who are self-employed or whose income comes from non-traditional sources, courts have additional tools. A judge can require a self-employed parent to deposit up to one year's worth of support into an interest-bearing account as a payment guarantee. Courts can also issue withholding orders against contract payments, commissions, and other non-wage income streams.
If you're not receiving payments through the automatic withholding system, or if the paying parent has changed jobs and the order hasn't caught up, contact your local child support agency (LCSA). These agencies provide free enforcement services to anyone with a court order in place.
What happens when a parent doesn't pay
One missed payment immediately becomes arrears, and California takes nonpayment seriously. Unpaid child support accrues 10% annual interest, and courts cannot reduce past-due amounts retroactively. The longer payments go unmade, the harder the financial hole becomes to climb out of.
Beyond wage garnishment, the California DCSS and Local Child Support Agencies have a range of enforcement tools they can use, often simultaneously:
- Tax refund interception. State and federal tax refunds can be seized and applied to arrears before the paying parent receives them.
- Bank levies. Funds in checking accounts, savings accounts, and some investment accounts can be frozen and seized, sometimes with little advance notice.
- Property liens. A lien can be filed against real estate, vehicles, and other assets, preventing the sale or refinancing of property until the debt is satisfied.
- License suspension. After 30 days of delinquency, DCSS can move to suspend a parent's driver's license, professional license, occupational license, or recreational license if arrears exceed $2,500. Reinstatement requires proof of compliance.
- Passport denial. Parents who owe more than $2,500 in child support may be denied a passport or have an existing passport revoked through the federal Passport Denial Program.
- Credit reporting. Delinquent payments are reported to major credit bureaus, which can damage the paying parent's credit score and affect their ability to borrow, rent housing, or secure employment.
When other enforcement methods haven't resolved the nonpayment, a custodial parent or DCSS can file a contempt of court motion in family court. To succeed, you must show that a valid order existed, the other parent knew about it, and they willfully failed to comply. If found in contempt, a parent can face fines, community service, a conditional jail sentence, or actual jail time. Courts can sentence a parent to up to 120 hours of community service or jail time for each month of unpaid support, with penalties increasing for repeat violations.
In the most serious cases involving repeated, willful nonpayment, California law allows for criminal prosecution as a misdemeanor, carrying up to one year in jail and a $2,000 fine. If a parent crosses state lines to avoid paying, federal criminal charges may also apply when arrears exceed $5,000 or payments have been missed for more than a year.
It's worth noting that job loss or reduced income is not automatically a defense to contempt. Courts look at the full financial picture, including savings, investments, and other assets. If your circumstances have changed and you genuinely cannot meet the current order, the right move is to request a modification before arrears accumulate, not to stop paying and hope the situation resolves itself.
What to do if your circumstances change
Child support orders are not permanent. Either parent can request a modification when there has been a significant change in circumstances, such as a substantial change in income, a change in the custody arrangement or timeshare, a new child from another relationship, or a change in the child's needs.
A modification requires going back to court or working through DCSS. The new support amount will only apply going forward from the date the modification request was filed. Courts cannot reduce arrears that have already accrued. This is why acting quickly matters: if you know you're going to miss payments, file for a modification before you fall behind rather than after.
If you and your co-parent agree on a new amount, you still need court approval for it to be legally enforceable. A written agreement between the two of you, without a court order, won't protect you if the situation deteriorates later. Consider working with a Hello Divorce family law specialist or a divorce mediator to negotiate a modification both parties can live with, then formalize it through the court.
Frequently asked questions
Can I get child support if I was never married to the other parent?
Yes. Child support in California is based on parentage, not marital status. If paternity or parentage has been legally established, either through a voluntary declaration or a court order, you can seek a child support order through the family court system or with help from your local DCSS office. The process is the same regardless of whether the parents were ever married.
What if the other parent is self-employed or paid in cash?
Self-employment doesn't protect a parent from their support obligations. Courts can impute income based on the parent's earning capacity, review tax returns and bank records, and issue withholding orders directed at clients, payment processors, or other income sources. DCSS and family law attorneys have tools for identifying undisclosed income, including financial subpoenas and discovery requests.
How long does it take for enforcement to kick in after payments stop?
One missed payment immediately creates arrears. If you have an active DCSS case, the agency monitors payment patterns and can begin enforcement actions relatively quickly, particularly if wage garnishment is already in place and the paying parent has changed jobs. For faster results in complex cases, a private family law attorney can file contempt motions directly without waiting for DCSS to act.
Does child support end automatically when my child turns 18?
Generally, child support in California ends when the child turns 18 or graduates from high school, whichever comes later, up to age 19. However, the obligation to pay any existing arrears does not end. Unpaid child support can be collected indefinitely, and courts can renew judgments as needed to keep them enforceable. You must formally terminate the Income Withholding Order through the court; it does not stop on its own.
What is the difference between DCSS and a private attorney for enforcement?
DCSS provides free enforcement services and is effective for many cases, especially interstate enforcement and wage garnishment. A private family law attorney typically moves faster, can file contempt motions directly, pursue bank levies more aggressively, and build a legal record that matters if custody becomes an issue down the road. If your case is straightforward, DCSS is a solid starting point. If the other parent is hiding income, living out of state, or the amounts are significant, private legal help is usually worth the investment.
Can child support be reduced if the paying parent loses their job?
Job loss can be grounds for a modification, but it is not automatic protection against enforcement or contempt. The paying parent must file a formal modification request with the court. Until a judge approves a new amount, the existing order remains in force and arrears continue to accrue. Filing for modification as soon as possible after a job loss protects the paying parent from an unmanageable debt building in the background. Courts will not reduce arrears that accumulated before the modification was requested.
