San Diego Child Support Lawyers
Protecting Your Financial Rights and Your Child’s Future
Child support disputes affect more than the monthly payment. They affect financial stability, parenting arrangements, and each parent’s ability to move forward. Whether you are seeking a support order based on accurate income or defending against a calculation you believe is wrong, the stakes are real and the process is adversarial.
At Naimish & Lewis, APC, we represent parents on both sides of child support disputes in San Diego County. We handle straightforward guideline cases and complex contested matters, including cases involving disputed income, business ownership, high-earner deviations, and modification proceedings.
The outcome of a child support case is not just determined by what the formula says. It is determined by how well the relevant facts are developed, presented, and argued. That is where experienced legal representation makes a difference.
How Child Support Is Calculated in California
California uses a statewide guideline formula that calculates child support based on two primary factors: the percentage of time each parent spends with the child and each parent’s net disposable income. Both figures feed into a computer model that produces the guideline amount.
Net disposable income includes wages, salary, commissions, business income, rental income, retirement distributions, and other sources. Certain deductions are allowed, including taxes, health insurance premiums, and mandatory retirement contributions.
Add-on expenses are calculated separately and shared in proportion to each parent’s income. Common add-ons include:
- Work-related childcare costs
- Uninsured health and dental expenses
- Costs for special needs, educational programs, or extracurricular activities agreed upon by the parties
The guideline amount is presumptively correct under California law. Courts can deviate from it, but deviation requires meeting specific statutory criteria. In most cases, the dispute is not over the formula itself. It is over the income figures and time-share percentages being used to run it.
Where Child Support Cases Become Contested
Child support cases become contested when the underlying facts are disputed. The most common disputes involve income, earning capacity, and the appropriate characterization of financial resources.
Disputed and Underreported Income
In any case where one parent is self-employed, owns a business, or receives income through channels that do not appear on a W-2, income verification becomes a focal point of litigation. Courts consider:
- Business income net of legitimate expenses (not all business deductions reduce income for support purposes)
- Cash income that does not appear in tax returns
- Retained earnings, owner distributions, and perquisites flowing through a business
- Depreciation and other non-cash deductions that inflate apparent business losses
These disputes arise from both directions. One parent may argue the other is understating income. The other may argue that income is being overstated based on flawed assumptions about how the business operates. We represent clients on both sides.
Imputed Income and Earning Capacity
When a parent is voluntarily unemployed or working below their earning capacity, California courts may impute income based on what that parent could reasonably earn. The analysis looks at work history, education, job market conditions, and the availability of appropriate employment.
Earning capacity disputes are common in cases involving career changes, return-to-school decisions, business downturns, and situations where one parent claims they cannot find equivalent work. These issues are litigated through vocational evaluations, employment market evidence, and financial documentation.
High-Earner Deviations
Under California Family Code § 4057(b)(3), a court may deviate from the guideline when the parent ordered to pay has extraordinarily high income and the guideline amount would exceed the reasonable needs of the child. These cases require a careful analysis of what the child actually needs and what the guideline would produce, and they are frequently litigated.
High-income cases often involve complex compensation structures including executive salaries, bonuses, stock options and restricted stock units, carried interest, and business distributions. Presenting these accurately requires both legal and financial expertise.
Add-On Expenses and Reimbursement Disputes
Disputes over add-on expenses are among the most common post-judgment conflicts. Disagreements arise over what qualifies as a reimbursable expense, how costs should be documented, and how reimbursement timelines work. Enforcement of add-on obligations sometimes requires court involvement.
Child Support Modifications
A child support order is not permanent. Either parent can request a modification when there has been a material change in circumstances since the order was entered.
Common grounds for modification include:
- Significant change in either parent’s income, including job loss, promotion, or business changes
- Change in the custody or time-share arrangement
- A child’s change in needs, including medical conditions or educational expenses
- Termination of add-on expenses that were part of the original order
Modification proceedings are forward-looking and retroactive. Timing matters because under California Family Code § 3653, a modification order may be made retroactive to the date of filing in appropriate circumstances, though the effective date depends on the specific facts and procedural history of the case.
Acting promptly when circumstances change is important. Delay in filing can limit your ability to seek retroactive relief.
Enforcing Child Support Orders
When a parent fails to pay child support as ordered, California provides several enforcement mechanisms. These include:
- Wage and income withholding orders
- Seizure of tax refunds and lottery winnings
- Liens on real and personal property
- Suspension of professional, driver’s, and recreational licenses
- Contempt of court proceedings, which can result in fines or incarceration in serious cases
We assist clients in pursuing enforcement when a support order is not being followed, and we represent clients who have been named in enforcement proceedings and need to understand their options and rights.

Frequently Asked Questions
How is child support calculated in California?
California uses a statewide guideline formula based on each parent’s net disposable income and the percentage of time each parent spends with the child. The formula produces a presumptively correct amount, but courts can deviate when specific statutory criteria are met. In contested cases, the dispute usually centers on what income figures go into the formula, not the formula itself.
Can child support be modified after it is ordered?
Yes. Either parent can request a modification when there has been a material change in circumstances, such as a significant income change, a change in custody arrangements, or a change in the child’s needs. The timing of your filing matters because modification orders may be retroactive to the date you file in appropriate circumstances.
What happens if the other parent is hiding income?
Courts have tools to address unreported or concealed income, including subpoenas for financial records, requests for business documentation, and forensic accountant testimony. If you believe income is being concealed or understated, an attorney can help you build the evidentiary record needed to raise the issue effectively at a hearing.
What if I think my income is being overstated?
Overstated income claims are a common issue in cases involving self-employment, business ownership, or complex compensation. If you believe a support demand is based on an inaccurate income picture, there are procedural mechanisms to challenge the assumptions and present a more accurate financial analysis.
How long does child support last in California?
Child support generally continues until the child turns 18, or until age 19 if the child is still a full-time high school student and not self-supporting. Support may end earlier if the child marries, is emancipated, or enters active military service. Courts can also order child support beyond these ages in cases involving a disabled adult child.
What are add-on expenses?
Add-on expenses are child-related costs that are shared separately from the base support amount. Common add-ons include work-related childcare, uninsured medical and dental costs, and costs related to special educational needs. These are typically allocated between the parents in proportion to their respective incomes.
