Moradi Neufer LLP represents California parents as child support attorneys, helping establish, modify, and enforce support orders under California’s statewide guideline calculation. We work with families throughout California on straightforward support matters as well as cases involving self-employment, business income, or disputed finances. The right approach depends on each family’s income, custody arrangement, and specific circumstances.
If you are trying to understand how much child support may be owed, or whether an existing order still reflects your family’s circumstances, the first step is understanding how California’s guideline system applies to your specific facts. That’s true whether you’re just starting this process, responding to a request from the other parent, or dealing with an order that no longer makes sense given what’s actually happening in your life.
We help California parents work through child support matters, from routine guideline cases to ones complicated by self-employment income, business ownership, or a parent who has stopped paying.

A child support attorney’s work generally falls into a few categories: establishing a new order, responding to a request filed by the other parent, reviewing whether an existing order still fits your circumstances, pursuing or defending a modification, addressing enforcement when support isn’t being paid, and resolving arrears. Cases involving self-employment income, business ownership, disputed income, or a recent parenting-time change tend to require more work upfront, since the guideline calculation depends on accurate financial information from both parents.
How is child support calculated in California? California applies a statewide guideline formula under Family Code Section 4055 to every case, using each parent’s net disposable income and the amount of parenting time, or timeshare, the higher-earning parent has with the child. Courts run this calculation through certified software rather than by hand, and the result is presumed correct under Family Code Section 4057 unless a party shows the court a specific, legally recognized reason to deviate. This isn’t a simple percentage of one parent’s paycheck; it’s a formula that weighs both parents’ finances and the actual parenting arrangement together.
Guideline support is based on net disposable income, which generally includes wages, self-employment earnings, bonuses, and commissions, after certain allowable deductions. When income is inconsistent or hard to document, such as with a business owner or a parent paid partly in equity, the court can look more closely at what a parent is actually earning or reasonably capable of earning.
What does child support cover in California? Beyond the base guideline amount, California generally requires childcare costs related to a parent’s employment or training, and a child’s uninsured health care expenses, to be shared between the parents, typically in proportion to income. Health insurance coverage for the child is often addressed within the same order.
Does custody affect child support? Yes, directly. The guideline formula factors in each parent’s timeshare alongside income, so two families with similar earnings can end up with meaningfully different support amounts depending on how parenting time is actually split. This is also why a real change in the parenting schedule, not just a preference for a different amount, can be grounds to revisit an existing order. When custody itself is in dispute, our child custody attorneys often work alongside our support work on the same case.
Can child support be changed? Often, yes, when there has been a genuine, material change in circumstances since the order was made. Common examples include a significant increase or decrease in either parent’s income, a real change in the parenting time split, or a meaningful change in the child’s needs. A modification generally isn’t granted just because a parent believes the current number feels unfair; the request needs to reflect an actual change, supported by real financial documentation.
California’s guideline formula does not become optional for high earners; the same statutory approach applies regardless of income level, though how it plays out looks different at higher income ranges. How does California handle child support for self-employed parents? Self-employment and business income require closer scrutiny than a regular paycheck, since net income has to be established from business records rather than a simple pay stub. Bonuses, commissions, and equity compensation add another layer, since how consistently and predictably a parent earns that income affects how it’s factored into the calculation. Our attorneys regularly work through these issues alongside our broader complex financial issues practice, including matters involving startup and equity compensation.
What happens if a parent stops paying child support? Unpaid support generally continues to accrue as a legal debt rather than disappearing over time. California provides enforcement tools both through the family court directly and through the California Department of Child Support Services, the state agency responsible for establishing and enforcing support obligations statewide, including wage withholding and other collection mechanisms. The right path depends on the specific order and how long support has gone unpaid.
Can a parent request child support if the parents were never married? Yes. Child support in California is not dependent on the parents having been married; it’s tied to establishing parentage and then addressing support and custody through the family court, following largely the same guideline framework used in divorce cases. If paternity hasn’t been legally established yet, that’s often the necessary first step before a support order can be entered.
Most engagements start with a review of both parents’ income, the current or proposed parenting schedule, and any existing order. From there, we work to resolve what can be resolved through negotiation and direct exchange of financial information, while preparing the documentation a contested hearing would require if the case doesn’t settle that way. When support issues arise alongside a broader divorce, they’re typically handled together with property division and other issues in the same case.
We help California parents with child support matters ranging from straightforward guideline calculations to cases involving business ownership, variable income, or a parent who isn’t complying with an existing order. We can’t guarantee a specific outcome, since every case depends on the particular facts and finances involved, but we can help you understand what the guideline formula is likely to produce given your actual circumstances and what your options are from there.
If you’re dealing with a child support question, whether it’s establishing an order, responding to one, addressing a change in circumstances, or dealing with unpaid support, contact Moradi Neufer or call one of our California offices to schedule a consultation.
1. How is child support calculated in California?
California applies a statewide guideline formula under Family Code Section 4055, which uses both parents’ net disposable income and the amount of parenting time, or timeshare, the higher-earning parent has with the child. The result is presumed correct unless a party shows a specific legal basis to deviate.
2. What does child support cover in California?
Beyond the base guideline amount, California generally requires certain child-related costs, like work-related childcare and a child’s uninsured medical expenses, to be shared between the parents, typically based on their respective incomes. Health insurance for the child is often addressed within the same order.
3. Does custody affect child support?
Yes. The guideline formula directly incorporates each parent’s timeshare alongside income. A meaningful change in the actual parenting schedule can be a legitimate basis to request a modification of an existing support order.
4. Can child support be changed?
Often, yes, if there has been a genuine, material change in circumstances since the order was entered, such as a significant income change, a real shift in the parenting schedule, or a change in the child’s needs. It generally isn’t granted simply because a parent wants a different number.
5. Can a parent request child support if the parents were never married?
Yes. Child support isn’t dependent on marriage. For unmarried parents, establishing parentage is typically the first step, after which support is addressed through largely the same guideline framework used in divorce cases.
6. What happens if a parent stops paying child support?
Unpaid support generally continues to accrue as a legal debt rather than disappearing over time. California offers enforcement tools through the family court and through the California Department of Child Support Services, including wage withholding.
7. How does California handle child support for self-employed parents?
Self-employment income is included in the guideline calculation, but it typically requires more documentation than a standard paycheck, since the court needs an accurate picture of actual net income from business or self-employment records.
8. What income is considered for child support?
Net disposable income generally includes wages, self-employment earnings, bonuses, and commissions, among other sources, after certain allowable deductions. When income is inconsistent, the court may need to look more closely at what a parent is actually earning.
