Child Custody and Visitation in Northern California, California
A plain-language guide to child custody across Northern California, from the forms you file at your county's Superior Court to mediation, the best-interest standard, and how to prepare your paperwork without hiring an attorney.
This page covers child custody in 13 of California's smaller, largely rural northern counties: Mendocino and Del Norte on the coast, Tehama, Glenn, Colusa, Sutter, and Yuba in the Sacramento Valley, Siskiyou, Lassen, Modoc, Trinity, and Plumas in the mountains and high desert, and Lake around Clear Lake. Each keeps its own Superior Court and hears custody cases exactly the way any California county does. They are grouped on one page because they share the same practical realities of a small county, not because the law is different.
Custody law is identical everywhere in California, including in every county listed here. It splits into legal custody, the authority to make major decisions about a child's health, education, and welfare, and physical custody, where the child primarily lives. Either can be joint or sole, and a judge decides based on the best interest of the child, with no preference for either parent's gender. Custody can be requested inside a divorce or legal separation, or, for parents who were never married, after a parentage case establishes the legal parent-child relationship.
What differs in a county this size is mostly practical. Many of these counties route all family law matters through a single courthouse in the county seat, distances between communities can be considerable, and Family Court Services or the self-help center may have more limited hours or staffing than a metro county. Confirm the correct courthouse, current hours, and whether phone or video mediation appointments are offered before you travel, using the official California Courts court finder. Parents who can agree on a parenting plan can skip a contested hearing entirely by submitting a written stipulation for a judge to sign, often the fastest and least costly path in a rural county.
If domestic violence is part of your situation, you can ask the court about a domestic violence restraining order (Forms DV-100 and DV-110), which can include temporary custody and visitation terms while your case is pending. Call 911 in an emergency, and the National Domestic Violence Hotline, 1-800-799-7233, is available 24 hours a day.
Custody courts by county in Northern California
Mendocino County
Mendocino County stretches from the redwood coast at Fort Bragg inland to Ukiah, the county seat, and up to Willits along the Highway 101 corridor. Because the county spans both coastal and inland communities, confirm which Superior Court of California, County of Mendocino location and mediation schedule applies to your case before filing.
Lake County
Lake County is built around Clear Lake, with Lakeport, the county seat, and the larger city of Clearlake sitting on opposite shores. Custody matters for both cities and the smaller lakeside communities between them are heard by the Superior Court of California, County of Lake, generally through a single courthouse.

Tehama County sits along the Sacramento River in the upper Sacramento Valley, with Red Bluff as the county seat and Corning to the south. The Superior Court of California, County of Tehama hears custody cases for both cities and the surrounding rural area.
Siskiyou County
Siskiyou County is a large, mountainous county in the far north, with Yreka as the county seat and Mount Shasta and Weed strung along the Interstate 5 corridor. Given the distances between communities, confirm which courthouse and mediation appointment schedule applies to your case before filing.

How custody is decided in California
California uses the same statewide rules in every county, including all of the counties in Northern California. Custody has two parts: legal custody (who makes major decisions about health, education, and welfare) and physical custody (where the child lives). Either can be joint (shared) or sole (one parent). Judges decide custody based on the best interest of the child, and California law does not favor a parent based on gender.
You can ask for custody orders inside a divorce or legal separation case, or, if the parents were never married, by first establishing parentage. The core steps are:
- Open or use an existing case: a divorce (Form FL-100), a legal separation, or a parentage case (Form FL-200) for unmarried parents.
- File a Request for Order (Form FL-300) with the custody and visitation attachment (Form FL-311) to ask the court for orders.
- Serve the other parent and file a proof of service.
- Attend the mandatory child custody mediation (Family Court Services), which California requires before a contested custody hearing.
- Attend the hearing if you have not agreed, and receive the court's order (Form FL-341 series, Findings and Order After Hearing on Form FL-340).

Northern California Child Custody FAQs
Which court hears my custody case in a county like Mendocino, Siskiyou, or Modoc?
Each of these counties keeps its own Superior Court, named for the county (for example, the Superior Court of California, County of Siskiyou), and most route family law filings to a single courthouse in the county seat. Use the official California Courts court finder to confirm the exact location and current procedures before you file.
Is child custody mediation required in these counties?
Yes. California requires parents in a contested custody or visitation dispute to attend child custody mediation through Family Court Services before a judge will rule, and that applies in every county on this page. Given limited staffing in some smaller counties, ask whether phone or video mediation appointments are available.
How does a judge decide custody in a small Northern California county?
The same way as everywhere else in California: based on the best interest of the child, weighing factors like stability and each parent's ability to provide care, with no preference for either parent's gender. Legal custody and physical custody are decided separately, and each can be joint or sole.
Can I complete my own custody paperwork without a lawyer?
Yes, self-representation is common in these smaller counties, and each court's self-help center can explain the required forms and steps. Virdix is a document preparation service, not a law firm, and can help you complete the required Judicial Council forms accurately, but it does not give legal advice or represent you in court.
