    Child Support in Sutter County, California

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

    A parent preparing a child support filing in Sutter County

    Sutter County's child support agency is not a Sutter County-only office. It is the Colusa, Sutter, and Yolo Regional Child Support Agency, based at 1007 Live Oak, Suite B2 in Yuba City. It serves parents across all three counties from that single location. That regional setup is the first thing to know before you start a case here.

    The courthouse itself is Sutter County-specific: 1175 Civic Center Blvd, Yuba City, CA 95993. The court offers eFile for general filings. It also runs a Tyler Technologies Guide and File system specifically for restraining orders, which does not apply to a standard support case. For child support, plan on eFile or in-person filing of Form FL-300 with an FL-150 income declaration.

    Support amounts are set under Family Code 4055 statewide. The calculation uses each parent's net income and the percentage of time the child spends with each parent. Get a free estimate at childsupport.ca.gov before you file.

    A fee waiver, Form FW-001, is available if the filing fee is a barrier. Once an order is entered, California generally attaches an automatic income withholding order to the paying parent's wages. That rule applies the same way whether the case was opened through the regional agency or filed directly with the court.

    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 Sutter 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 Sutter County

    Child support in Sutter County is handled through the Superior Court of California, County of Sutter, 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.

    Local notes for Sutter County

    Because the regional agency covers Colusa, Sutter, and Yolo counties together, a Sutter County parent working with the agency on collections deals with the same office and staff as a parent from Colusa or Yolo. That can help the agency work efficiently, but call volume may be higher than at a single-county office.

    The courthouse's direct phone number is not confirmed on its website. If you need to reach the clerk before filing, start with the court's general contact page or the self-help resource at sutter.courts.ca.gov/self-help/family-law-facilitator.

    The Tyler Guide and File tool the court advertises is built for restraining order petitions, not child support filings. Use eFile or an in-person visit for your FL-300. Live Oak parents are still served by the Yuba City courthouse and the same regional agency address, since Sutter County does not split family law filings across multiple branch locations the way some larger counties do.

    Sutter County Child Support FAQs

    Where do I file for child support in Sutter County?

    File Form FL-300 with an FL-150 income declaration at the courthouse, 1175 Civic Center Blvd, Yuba City, through eFile, or by contacting the Colusa, Sutter, and Yolo Regional Child Support Agency, 1007 Live Oak, Suite B2, Yuba City, which handles Sutter County's support cases. Confirm the current procedure with the clerk before filing.

    Why is my Sutter County child support case handled by a regional agency?

    Sutter County shares its child support agency with Colusa and Yolo counties under the Colusa, Sutter, and Yolo Regional Child Support Agency, based at 1007 Live Oak, Suite B2 in Yuba City. That single office establishes parentage, sets guideline orders, and collects payments for all three counties, so Sutter County parents do not have a county-only office. Because the agency handles three counties together, a Sutter County parent calling in should be ready to give a full mailing address so staff can route the case to the right file.

    Can I e-file child support paperwork in Sutter County?

    Yes. The court offers general eFile for documents like Form FL-300. The court's Tyler Technologies Guide and File system is built specifically for restraining order petitions, not child support, so use standard eFile or file in person at 1175 Civic Center Blvd for a support case.

    How is child support calculated in Sutter County?

    Sutter County follows Family Code 4055, California's statewide guideline formula, based on each parent's net disposable income and the timeshare split for the child. The regional agency setup does not change the math. Run the free guideline calculator at childsupport.ca.gov before you file. If either parent's income or the custody schedule changes after the order is set, you can use the same eFile system and FL-300 process to request a new amount.

    Is there free help for parents filing without a lawyer?

    Sutter County's self-help center and family law facilitator, listed at sutter.courts.ca.gov/self-help/family-law-facilitator, can explain forms like FL-150 and FL-300, but cannot advise on the outcome of your case. Exact hours are not posted, so call the courthouse to confirm before visiting. The facilitator can also point self-represented parents toward the Tyler Guide and File tool if a related restraining order matter comes up alongside the support case.

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

    Ask the clerk for Form FW-001, the Request to Waive Court Fees, when you file your child support paperwork. If your income qualifies, the court can waive the fee. The regional agency can also answer fee questions if you are opening a case through them instead.

    This page is general information about California child support procedure in Sutter 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 Sutter or the official California self-help center resources.
