If you are going through a divorce or separation in California and children are involved, child support is likely one of the first things on your mind. You might not know where to start, and that is completely normal. California has a specific set of rules for how child support works, and the process can feel overwhelming at first glance. This guide breaks it all down in plain language so you know what to expect.
Child support is a monthly payment one parent makes to the other to help cover the costs of raising a child. Both parents are legally required to support their children financially, even if they do not live together. The court is involved when parents cannot agree on their own.
What Is Child Support in California?
Child support in California is a court-ordered, monthly financial obligation. It is money paid by one parent to the other to help pay for a child’s everyday needs. This includes things like housing, food, clothing, education, and medical care. The obligation applies to both parents, no matter what their living situation looks like.
In California, child support is not just a suggestion from the court. It is legally binding, and there are real consequences for parents who do not follow through. Both parents share the responsibility for raising a child financially, and the court takes that seriously.
How Do Parents Share This Responsibility?
Ideally, parents come to an agreement outside of court. When they do, they can create what is called a stipulated agreement. This agreement is reviewed by a case worker and then submitted to the court. If the judge approves it, no formal hearing is needed. This can save time and stress for everyone.
When parents cannot agree, either parent or the child’s legal guardian can ask the court to set a child support order. A judge will then review both parents’ financial situations and decide on an amount.
How Child Support Is Calculated in California
California uses a statewide formula to calculate child support. This formula is written into Family Code Section 4055. Judges are required to follow this guideline in almost all cases. The only exceptions are when both parents agree to a different amount or when the court finds extraordinary circumstances.
Judges use computer programs like DissoMaster or X-Spouse to run the numbers. If the county’s Department of Child Support Services is involved, they use the child support calculator on their own website. These tools apply the same statewide formula and produce a monthly guideline support amount.
The Three Main Factors in the Formula
Three things carry the most weight in the calculation:
- How many children are involved
- How much time each parent spends with the children (called timeshare)
- The monthly income of each parent
The more time you have with your children, the lower your child support payment tends to be. This is true whether you are the paying parent or the receiving parent. The formula rewards parents who are more involved in day-to-day care.
What Counts as Income for Child Support?
Family Code Section 4058 gives a broad definition of income. It covers almost every source of money a person receives. The list includes wages, salaries, commissions, bonuses, royalties, rents, dividends, pensions, interest, annuities, trust income, workers’ compensation benefits, unemployment insurance, disability insurance, and Social Security benefits.
For self-employed parents, income is calculated differently. The court looks at gross receipts from the business minus the expenses needed to run it. The IRS allows more deductions than California’s Family Code does. Expenses like depreciation, travel, meals, and entertainment are typically not deductible for child support purposes. If a parent claims these costs, a judge will decide whether they were truly required to operate the business.
Two things that do not count as income are child support payments you are already receiving for a child, and income from public assistance programs based on financial need.
Both parents are required to file a complete Income and Expense Declaration, known as Form FL-150, before any child support hearing. This form is signed under penalty of perjury. W-2 employees should bring their last two months of pay stubs and the most recent year’s tax return to the hearing. Self-employed parents need to provide two years of profit and loss statements or a Schedule C from the most recent business tax return.
Expenses That Affect the Calculation
Certain monthly expenses can change the support amount. Some expenses raise the guideline amount for that parent, and some lower it.
Expenses that may increase the guideline support amount:
- Mortgage interest
- Real property taxes
Expenses that may decrease the guideline support amount:
- Health insurance premiums
- Mandatory retirement contributions
- Union dues
- Child support paid for children from other relationships
What If a Parent Is Underemployed or Hiding Income?
Under Family Code Section 4058(b), a court can assign an income to a parent based on what they are capable of earning, not just what they are currently making. This is called imputation of income. It comes up when a parent has a history of earning more and seems to be working less on purpose to avoid paying support.
In situations like this, a vocational examiner can be hired to evaluate what the parent is realistically able to earn and testify about that in court.
Courts also look closely at money that comes in as “loans” from family members or friends. Under the holding in Marriage of Alter, regular and recurring gifts that function like income can be treated as income available for child support. Just calling something a loan does not make it one.
Deferred salary is another area courts watch carefully. In Marriage of Berger, a father loaned his startup company $250,000, paid himself only $2,000 per month, and deferred $350,000 in salary. The court held that the deferred income still counted as income available for child support. Trying to shift money around to lower a support payment rarely goes unnoticed.
In high-asset cases, it may be necessary to hire a forensic accountant to examine a parent’s full cash flow before the hearing.
Add-Ons Beyond Base Child Support
Base child support covers the basics, but it is not the only financial obligation. Under Family Code Section 4062, both parents are typically each responsible for half of certain additional costs. These add-ons can include:
- Child care costs so the custodial parent can work
- Uninsured medical, dental, orthodontia, and counseling expenses
- Travel costs related to visitation
- Education and extracurricular activity expenses
These costs are shared 50/50 between both parents. They are separate from the base monthly support amount, so it is important to factor them into your overall financial picture when going through this process.
The Child Support Process, Step by Step
Getting a child support order in place involves a series of steps. Here is how the process typically works from start to finish:
1. Opening a Case
Either the parent or the child’s legal guardian can open a child support case by filing an application with the local child support agency. This is the starting point. In some situations, this step can be handled without ever going to court.
2. Locating Both Parents
The agency may need to locate one or both parents. Having information like birth dates and Social Security Numbers on hand makes this step much faster.
3. Receiving a Summons and Complaint
Once the case moves forward, the parent being asked to pay support receives a Summons and Complaint packet. This is an official legal notice that a child support lawsuit has been filed. You have 30 days to respond. If you do not respond within that window, the court can issue a default child support order without considering your financial situation at all.
4. Establishing Legal Parentage
If there is any question about who the legal parent is, this step is where it gets sorted out. A parent can request DNA testing or provide proof that the parents were legally married when the child was born. If no proof is provided, the court may still designate someone as the legal parent.
5. Reaching a Stipulated Agreement
Before a court date is set, parents have the option to meet with a child support case worker and work out a payment agreement together. If both sides agree, this stipulated agreement gets submitted to the court. The judge reviews it, and if it is approved, there is no need for a court hearing at all.
6. The Court Sets the Order
If no agreement is reached, the case goes before a judge. The judge looks at both parents’ financial information, including income, expenses, parenting time, and medical insurance costs, and then sets the monthly child support amount. In California, a Request for Order (RFO) is how either party formally asks the court to schedule this hearing. A hearing date is typically set about 45 days after the RFO is filed.
7. Making or Receiving Payments
Once the order is in place, payments begin. For working parents, child support is usually withheld directly from their paycheck by their employer. There are other payment options too, but wage withholding is the most common method.
8. Enforcing the Order
Child support orders are legally binding. If a parent stops paying, enforcement can include:
- Suspension of a driver’s license or passport
- Revocation of professional licenses
- Property and bank liens
- Interception of tax refunds and lottery winnings
On top of enforcement actions, a parent who repeatedly refuses to pay may face contempt of court. Family court judges handle all related issues together, so it is in everyone’s best interest to stay in good standing with the court.
9. Modifying the Order
Life changes. If you lose a job, change employment, or experience a shift in custody or visitation arrangements, you can ask the court to modify the child support order. You cannot simply stop paying because your situation changed. You need to go back to the court and make it official.
10. Closing the Case
A child support case typically closes when the youngest child reaches adulthood, and there are no remaining unpaid balances. After a case closes, records are kept for an additional four years and four months, as required by federal law.
How Child Support and Child Custody Relate to Each Other
Child support and child custody are legally separate issues. A judge does not automatically address both at the same time. If you want the court to handle child support, you have to specifically request it. The same goes for custody.
That said, the two are closely connected in practice. The amount of time a parent spends with a child directly affects how much support is owed. More parenting time generally means lower support payments for that parent. Because of this, both requests are almost always made at the same time.
It is also worth knowing that failing to pay child support should not, on its own, affect custody arrangements. The court treats them as separate matters. That does not mean there are no consequences for non-payment, just that custody should not be used as leverage over support.
When Does Child Support End in California?
In most cases, child support ends when a child turns 18 and graduates high school. If the child is still in school full-time and cannot support themselves, the obligation may continue until the child turns 19 or graduates, whichever comes first.
Child support also ends when any of the following happen:
- The child gets married
- The child enters a domestic partnership
- The child joins the military
- The child is legally emancipated
- The child passes away
If a child has a disability and is unable to support themselves, the court may extend the child support obligation past age 18 or 19.
