Child Support in Siskiyou County, California

Siskiyou County sits in rural Northern California, and its family courts and local child support agency handle support cases for families in Yreka, Mount Shasta, and Weed. A child support case here runs through the Superior Court of California, County of Siskiyou and the county's Local Child Support Agency.

Child support in California follows one statewide guideline formula (Family Code section 4055), based mainly on both parents' net disposable incomes and the share of time the child spends with each parent, the timeshare. The guideline amount is presumed correct, and it works no differently in Siskiyou County than anywhere else in California.

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.

Since income and timeshare drive the result, it is worth estimating before you file. You can use our free California Guideline Child Support Calculator at /tools/california-child-support-calculator, and if both parents agree on an amount, you can submit a written stipulation for a judge to sign.

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 Siskiyou 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.
