Child Support in Ventura County, California

Ventura County runs along the Southern California coast and inland valleys, home to Oxnard, Thousand Oaks, Simi Valley, the city of Ventura, and Camarillo. Families throughout the county handle child support cases through the Superior Court of California, County of Ventura, and the county's Local Child Support Agency.

Ventura County follows California's single statewide guideline formula for child support, set out in Family Code section 4055, the same as every other county. The formula combines both parents' net disposable incomes with the timeshare, meaning the percentage of time the child spends with each parent, into a number the law presumes to be correct.

There are two routes to a support order in Ventura County. A parent already involved in a divorce, parentage, or custody case can file a Request for Order (Form FL-300) with an Income and Expense Declaration (Form FL-150). Or the county's Local Child Support Agency, part of the statewide Department of Child Support Services, can open a case directly to establish and enforce support. The forms are identical statewide; what's specific to Ventura County is which courthouse hears the case and where the local agency office is.

Before filing, it's useful to have a sense of the likely number. Try our free California Guideline Child Support Calculator at /tools/california-child-support-calculator. Parents who already agree on an amount can also submit a written stipulation for a judge's signature instead of a contested hearing.

How child support is calculated in California

California sets child support with a statewide uniform guideline (Family Code section 4055) that applies the same way in Ventura County as everywhere else. The formula is based mainly on two things:

1. Both parents' net disposable incomes.
2. The percentage of time the child spends with each parent (the timeshare).

The guideline amount is presumed to be correct, and courts use a calculator to run the numbers. Because the result depends on accurate income, the Income and Expense Declaration (Form FL-150) you file is what drives your number.

Where child support cases are handled in Ventura County

Child support in Ventura County is handled through the Superior Court of California, County of Ventura, with the county seat in Ventura, and the county's Local Child Support Agency, which is part of the California Department of Child Support Services. There are two common paths:

1. Either parent files a Request for Order (Form FL-300) with an Income and Expense Declaration (Form FL-150) inside a divorce, parentage, or custody case.
2. The Local Child Support Agency opens a case to establish, collect, and enforce support, often at no cost to the parents.

Because courthouse locations and the local agency office change over time, confirm current details using the official California Courts court finder:

Local notes for Ventura County

Confirm the correct courthouse for your case in Ventura County using the official California Courts court finder, since family law filings are directed to a specific location. The county's Local Child Support Agency maintains its own office separate from the court; current information is available through the California Department of Child Support Services website.

Ventura County's self-help center helps self-represented parents complete Form FL-150 and related forms and can explain the general court process, though staff cannot give legal advice about your particular situation. Because the guideline outcome is driven directly by the income figures reported, being thorough and accurate on that declaration is the most important part of the filing.

Consistent with California law statewide, child support in Ventura County generally continues until the child turns 18, or 19 if the child is still a full-time high school student living at home and not self-supporting. Either parent can request a modification later if income or the parenting timeshare changes.
