    Child Support in Yuba County, California

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

    A parent preparing a child support filing in Yuba County

    Yuba County has required electronic filing since July 1, 2018. That is longer than most rural California counties. The court uses File @ Home, built on the Tyler Technologies platform at california-efm.tylertech.cloud. A child support case here is expected to be filed online, not brought in on paper. The courthouse is still at 215 Fifth Street, Suite 200, Marysville, CA 95901, phone (530) 740-1800, for anyone who needs in-person help.

    Support amounts follow Family Code 4055 statewide. The calculation uses each parent's net income and the percentage of time the child spends with each parent. Yuba County's mandatory e-filing rule does not change that. Use the free calculator at childsupport.ca.gov, then file Form FL-300 with an FL-150 income declaration through File @ Home.

    The Yuba County Local Child Support Agency, at 5730 Packard Ave, Suite 200 in Marysville, can open a case, establish parentage, and collect payments. It usually does this without charging the parent who asks for help.

    If you cannot afford the filing fee, ask about Form FW-001 to request a waiver. Once an order is entered, California generally adds an automatic income withholding order to the paying parent's wages. Support then comes straight out of a paycheck. File @ Home tracks that along with the rest of the case record. A family law facilitator can also help a self-represented parent learn the File @ Home system itself, along with the FL-150 and FL-300 forms.

    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 Yuba 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 Yuba County

    Child support in Yuba County is handled through the Superior Court of California, County of Yuba, 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 and local agency office details change over time, confirm current details using the official California Courts court finder:

    Local notes for Yuba County

    Mandatory e-filing since 2018 means a self-represented Yuba County parent should expect to create a File @ Home account before submitting documents. Do not assume a paper option is available as a backup. Check with the clerk if you have trouble with the system.

    The Local Child Support Agency office on Packard Avenue is separate from the Fifth Street courthouse. A parent handling a collections case through the agency usually does not need to file anything through File @ Home directly.

    The self-help center and family law facilitator can help with forms and the e-filing process itself. They cannot advise you on the likely outcome of a specific case. Exact hours aren't posted, so call before visiting. Wheatland parents use the same Marysville courthouse and Packard Avenue agency office because Yuba County doesn't split family law filings across branch locations.

    Yuba County Child Support FAQs

    Where do I file for child support in Yuba County?

    File Form FL-300 with an FL-150 income declaration through File @ Home, the court's mandatory e-filing system at california-efm.tylertech.cloud. You can also ask the Yuba County Local Child Support Agency, 5730 Packard Ave, Suite 200, Marysville, to open a case for you. Call (530) 740-1800 with questions before filing.

    Is e-filing required for child support cases in Yuba County?

    Yes. Yuba County has required electronic filing since July 1, 2018, through File @ Home, which is built on the Tyler Technologies platform. This rule has been in place longer than many mandatory e-filing rules in rural California counties. Plan to file your FL-300 and FL-150 online, not on paper.

    How is child support calculated in Yuba County?

    Yuba County uses Family Code 4055, California's statewide guideline formula. It is based on each parent's net disposable income and the timeshare split for the child. The mandatory e-filing rule does not affect the calculation. Use the free calculator at childsupport.ca.gov before filing to estimate your amount. If income or the custody schedule changes meaningfully after the order is set, either parent can file a new FL-300 through File @ Home to ask for a recalculated amount.

    What does the Local Child Support Agency handle in Yuba County?

    The agency, at 5730 Packard Ave, Suite 200 in Marysville, can establish parentage when needed. It can also calculate a guideline support order, collect payments, and enforce payments, generally at no direct cost to the parent requesting help. The agency is separate from the courthouse and does not require you to use File @ Home.

    Is there help for parents new to File @ Home in Yuba County?

    Yuba County's self-help center and family law facilitator can walk a self-represented parent through the required forms and the File @ Home e-filing process. Staff can't advise on the outcome of a specific case. Hours aren't posted online, so call the courthouse before visiting. Parents who don't already have a File @ Home login can typically create one during their first submission. The self-help center can walk through that setup step by step.

    What if I can't afford the Yuba County filing fee?

    Ask the clerk for Form FW-001, the Request to Waive Court Fees, when you submit your child support filing through File @ Home. If your income qualifies, the court can waive the fee. The self-help center can help if you're unsure how to attach the form electronically.

    This page is general information about California child support procedure in Yuba County, not legal advice for your situation. The calculator provides an estimate only, and the court determines the actual guideline amount. Court locations, agency offices, and filing details change; always confirm current details with the Superior Court of California, County of Yuba or the official California self-help center resources.
