Child Custody and Visitation in Sierra Nevada, California
A plain-language guide to child custody across Sierra Nevada, 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 9 of California's smaller Sierra Nevada and eastern Sierra counties: the Gold Country foothill counties of Nevada, Tuolumne, Calaveras, Amador, Mariposa, and Sierra, the high mountain county of Alpine, and Inyo and Mono along the eastern escarpment near Bishop, Mammoth Lakes, and Bridgeport. Each keeps its own Superior Court and hears custody cases the same way any California county does. They are grouped here because they share the practical realities of a small mountain county, not because the law differs.
Custody law is identical everywhere in California, including in every county on this page. 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 these counties is mostly practical. Most route all family law matters through a single courthouse in the county seat, mountain roads and winter weather can add real travel time, and Family Court Services or the self-help center may have more limited hours than a metro county, especially in a county as small as Alpine. 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 most practical route given the distances involved.
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.

How custody is decided in California
California uses the same statewide rules in every county, including all of the counties in Sierra Nevada. 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).

Sierra Nevada Child Custody FAQs
Which court hears my custody case in a county like Nevada, Mariposa, or Mono?
Each of these counties keeps its own Superior Court, named for the county, and most route family law filings to a single courthouse in the county seat. Because several of these counties span a wide mountain area, such as Nevada County reaching from Grass Valley to Truckee, use the official California Courts court finder to confirm the correct location before filing.
Is child custody mediation required in these Sierra Nevada 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 the smallest counties, such as Alpine and Sierra, ask whether phone or video mediation appointments are available.
How does a judge decide custody in a small Sierra Nevada 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.

Court locations, programs, and filing details change; always confirm current details with your county's Superior Court or the official California Courts self-help resources. If your case involves domestic violence, abduction risk, or a child's safety, contact the court's self-help center or a licensed California family law attorney, and in an emergency call 911.
