Child Support in Mendocino County, California

Mendocino County is a Northern California county of small towns and open country, serving families in Ukiah, Fort Bragg, and Willits. Child support cases are handled by the Superior Court of California, County of Mendocino and the county's Local Child Support Agency.

California sets child support with a statewide uniform guideline formula (Family Code section 4055). The amount depends mainly on both parents' net disposable incomes and the percentage of time the child spends with each parent, called the timeshare. That guideline result is presumed correct, and Mendocino County applies it the same way as the rest of the state.

You can reach a support order two ways: by filing a Request for Order (Form FL-300) with an Income and Expense Declaration (Form FL-150) in a divorce, parentage, or custody case, or by asking the county's Local Child Support Agency, part of the California Department of Child Support Services, to open and enforce a case. The formula and forms are the same statewide.

The result depends on accurate income and timeshare, so an estimate up front is useful.

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 Mendocino 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 Mendocino County

Child support in Mendocino County is handled through the Superior Court of California, County of Mendocino, with the county seat in Ukiah, 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 Mendocino County

Mendocino County handles these matters through its Superior Court in Ukiah, and its Local Child Support Agency runs an office for support cases. Confirm the correct courthouse using the official California Courts court finder, and find the county agency through the California Department of Child Support Services, before you file in person or by mail.

The county's self-help center helps parents who represent themselves complete Form FL-150 and understand court procedure, but staff cannot give legal advice about your specific case. Because the guideline result is driven by the income you report, filling out the Income and Expense Declaration accurately is the most important step.

Child support in California 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 ask the court to modify support when income or the parenting timeshare changes meaningfully.
