Child Support in Nevada County, California

Nevada County family law cases go through the Superior Court at 201 Church Street in Nevada City. A second courthouse, at 10075 Levon Avenue in Truckee, serves parents on the Tahoe side of the county. Either location may be the right place for a child support filing. Confirm with the clerk before driving to Nevada City if Truckee is closer to you.

One detail is specific to this area. The Local Child Support Agency, at 950 Maidu Avenue, Suite 140 in Nevada City, also serves neighboring Sierra County. A parent from either county uses the same office, the same phone line, and the same staff.

Support is calculated under Family Code 4055. That is the same statewide formula used in every California county. It is based on each parent's net income and the timeshare split. Run the free calculator at childsupport.ca.gov. Then file Form FL-300 with an FL-150 income declaration at the court, or ask the Local Child Support Agency to open the case for you.

The court offers Electronic Document Filing, but its site does not list the current e-filing vendor. Confirm the exact process with the clerk. A fee waiver, Form FW-001, is available if you cannot afford the filing fee. After a guideline order is in place, California generally puts an automatic income withholding order on the paying parent's wages. Payments then come straight from a paycheck instead of relying on a mailed check each month.

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 Nevada 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 Nevada County

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

Two courthouses create two sets of filing details. Nevada City handles most of Nevada County's family law docket. The Truckee branch exists because the drive over the mountain from Tahoe-area towns to Nevada City is long, especially in winter. Ask which courthouse your case belongs in before filing.

The Local Child Support Agency covers both Nevada and Sierra counties from one Nevada City office. A Sierra County parent does not have a separate local office. Everyone goes through Maidu Avenue. This matters when you are trying to figure out where a support case is handled.

The self-help center and family law facilitator can help a self-represented parent work through FL-150 and FL-300. They cannot give legal advice for a specific case. Current drop-in hours aren't posted, so calling ahead can prevent a wasted trip. With two courthouses and the shared Sierra County caseload, a parent who calls should be ready to give a home address. Staff may also ask whether the other parent lives near Truckee or Nevada City, because that can affect where a hearing is set.
