Child Custody and Visitation in Marin County, California
A plain-language guide to child custody in Marin County, from the forms you file at the Superior Court of California, County of Marin to mediation, the best-interest standard, and how to prepare your paperwork without hiring an attorney.
Marin County sits just north of the Golden Gate Bridge, a compact and affluent county of small cities and unincorporated hillside towns. Parents in San Rafael, Novato, Mill Valley, Larkspur, San Anselmo, and elsewhere in the county bring their custody matters to the Superior Court of California, County of Marin, seated in San Rafael.
California custody law does not change from one side of the Golden Gate to the other. It splits into legal custody, the authority to make major decisions about a child's health, education, and welfare, and physical custody, which parent the child lives with day to day. A judge can order either as joint or sole, and the law does not favor a mother or a father; the only question is the best interest of the child.
Custody comes up two ways: as part of a divorce or legal separation, or, for parents who were never married, through a separate parentage action that establishes legal fatherhood or motherhood before custody can be ordered. Either path uses the same statewide Judicial Council forms that every California county uses, so the differences you will notice in Marin are procedural, like which courthouse handles the filing and how mediation appointments get scheduled.
Parents who see eye to eye on a parenting plan do not have to go through a contested hearing. They can write out their agreement, sign it, and submit it for a judge to review and sign, which is typically quicker and less stressful than litigating the issue in front of a courtroom.

How custody is decided in California
California uses the same statewide rules in every county, including Marin County. 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).
There is no six-month waiting period for custody the way there is for a divorce to become final. Parents can also agree on a parenting plan and submit it as a stipulation for the judge to sign, which avoids a contested hearing entirely. If you and the other parent agree, that is almost always the faster and less costly path in Marin County.
Local notes for Marin County
Marin is a smaller county, and family law matters are generally handled at the Marin County Civic Center courthouse in San Rafael, but confirm the exact courtroom and filing counter for custody matters using the official California Courts court finder before you appear.
Like every county in the state, Marin requires parents in a contested custody or visitation dispute to complete child custody mediation through Family Court Services before a judge will hear the case. The goal is to help parents reach their own agreement with a neutral mediator. If you are representing yourself, the court's self-help center can walk you through required forms and deadlines, but staff there cannot advise you on strategy or tell you what to ask for.
If domestic violence is part of your situation, you can ask the court for a domestic violence restraining order using Forms DV-100 and DV-110, which may include temporary custody orders while the case is pending. Call 911 if you are in immediate danger, and the National Domestic Violence Hotline, 1-800-799-7233, takes calls day and night.

Marin County Child Custody FAQs
Which court handles child custody cases in Marin County?
Custody matters in Marin County are heard by the Superior Court of California, County of Marin, based in San Rafael. Confirm the specific courthouse and filing requirements with the official California Courts court finder before submitting your paperwork.
How does a Marin County judge decide custody?
A judge applies the same best interest of the child standard used across California, weighing the child's health, safety, and stability rather than favoring either parent. Legal custody covers decision making authority, while physical custody covers where the child lives, and both can be awarded jointly or solely.
Do Marin County parents have to try mediation first?
Yes. If parents cannot agree on custody or visitation, California law requires them to attend mediation through Family Court Services before the matter goes to a contested hearing. Many parents reach an agreement during mediation and never need a full hearing.
Can I handle a Marin County custody filing myself?
Self-represented parents are common in family court, and Marin's self-help center offers procedural guidance for people filing on their own. A document preparation service like Virdix can help you fill out the required Judicial Council forms correctly, but it is not a law firm, does not give legal advice, and cannot represent you in court.
