A plain-language guide to child support in Fresno County, from California's statewide guideline formula to the forms you file at the Superior Court of California, County of Fresno, the local child support agency, and how to estimate your number and prepare your paperwork without hiring an attorney.

Fresno County anchors the heart of the Central Valley, with Fresno itself as the county's largest city alongside Clovis, Sanger, Reedley, and Selma. Families throughout Fresno County handle child support matters through the Superior Court of California, County of Fresno, and the county's Local Child Support Agency.
Child support in Fresno County, as everywhere in California, is calculated using the state's uniform guideline formula under Family Code section 4055. That formula looks at both parents' net disposable incomes and the timeshare, meaning how much time the child spends with each parent, to reach an amount the law presumes is correct.
Parents in Fresno County have two ways to get to a support order. If there's already a divorce, parentage, or custody case open, either parent can file a Request for Order (Form FL-300) with an Income and Expense Declaration (Form FL-150). Otherwise, 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 the same statewide; the local details are which courthouse hears the case and where the agency's office is.
Before filing, it helps to have a sense of the number. Our free California Guideline Child Support Calculator at /tools/california-child-support-calculator can give you an estimate based on income and timeshare. If both parents already agree, they can submit a written stipulation for a judge to sign instead of a contested hearing.

Fresno County's self-help center supports parents representing themselves in completing Form FL-150 and related paperwork and can walk through the general process, though staff cannot give legal advice about your particular case. Given that agricultural and seasonal work is common in Fresno County, reporting accurate and complete income figures on that form is especially important, since it's what the guideline calculation actually runs on.
Child support in Fresno County generally continues until the child turns 18, or 19 if the child is a full-time high school student still living at home and not self-supporting, the same rule that applies statewide. Either parent can ask the court for a modification later if income or the parenting timeshare changes.
Fresno County uses California's statewide guideline formula (Family Code section 4055), based on both parents' net disposable incomes and the child's timeshare between homes. This applies the same way in Fresno as in any other California county. Try our free California guideline child support calculator to estimate your number.

The guideline formula relies on the income figures reported on the Income and Expense Declaration (Form FL-150), so accurately reflecting seasonal or variable income there matters for the result.
