Understanding Child Custody in California: A Parent's Guide

This is an educational overview of how child custody generally works in California, written for parents, not lawyers. It isn't legal advice, and California family law can turn on the specifics of your situation. For anything beyond general understanding, talk to a licensed California family law attorney or use the official California Courts Self-Help Center.

The two kinds of custody

California splits custody into two separate questions:

• Legal custody: who makes major decisions about education, health care, and religious upbringing. This can be joint (both parents decide together) or sole (one parent decides).
• Physical custody: where the child actually lives day to day. This can also be joint or sole, and it's decided independently of legal custody.

It's entirely normal to have joint legal custody (both parents involved in big decisions) alongside a physical custody split that isn't 50/50. One doesn't require the other.

There's no legal presumption in California favoring either parent, or favoring joint custody over sole custody. Judges decide based on the best interest of the child in each specific case (Family Code § 3040 through § 3049).

How it actually works: mediation first

If parents can't agree on custody, California requires mediation before a judge will hear a contested case (Family Code § 3170). This happens through Family Court Services, is typically free, and is scheduled shortly before your hearing date.

A concrete example: Maria and David can't agree on a schedule during their divorce. Before their court date, they're both required to meet with a Family Court Services mediator, sometimes together, sometimes separately if there's a safety concern. If they reach an agreement, it becomes a proposed order for the judge to sign. If they don't, depending on the county, the mediator may submit a recommendation, or the case proceeds to a contested hearing.

Most custody disputes in California resolve at or before this stage. A full contested hearing, and possibly a formal custody evaluation, is reserved for cases mediation doesn't settle.

Common custody schedules used in California

California doesn't set a single "standard" schedule the way some states do. What's common in practice:

• 2-2-3: frequent handoffs, often used for younger kids
• Week on, week off: fewer handoffs, common for school-age kids and up
• Every other weekend: one parent has weekdays, the other has alternating weekends, common when one parent's schedule or distance makes frequent handoffs impractical

Judges generally don't impose a specific pattern by default, they look at what serves the child given their age, school, and each parent's circumstances. See how to choose a custody schedule for a framework, and the custody schedule generator to build the actual calendar once you've settled on a pattern.

Moving with your child (move-away cases)

If you have an existing custody order and want to relocate with your child, whether you can depends heavily on your current arrangement:

• If you have primary physical custody and no order restricts moving, you generally have the presumptive right to relocate, unless the other parent shows the move would be detrimental to the child.
• If custody is closely shared, or your order restricts relocation, moving usually requires the other parent's agreement or a new court order.

California courts weigh what are commonly called the LaMusga factors (from In re Marriage of LaMusga, 2004, building on In re Marriage of Burgess, 1996): the child's age, the distance of the move, the child's relationship with each parent, each parent's ability to cooperate, the reason for the move, and the current custody split, among others. No single factor decides the case.

Example: if a parent with primary physical custody wants to move two hours away for a new job, and the current schedule involves frequent midweek exchanges, a court will look at whether a modified schedule (like alternating longer blocks instead of weekly exchanges) can preserve both parents' relationships with the child, not simply block or approve the move outright.

Decisions and support

Child support is calculated using California's statewide guideline formula, based on both parents' incomes and the percentage of time each has physical custody. The state provides an official guideline calculator through the Department of Child Support Services.

Grandparent visitation is possible but limited, generally only when the parents are separated, one parent is deceased, or another specific statutory condition applies (Family Code § 3100 and following).

How OnePage fits in

None of this changes because of an app, custody orders come from mediation or a judge. What a shared calendar and message log help with is the day-to-day part that comes after the order is in place: keeping both parents looking at the same schedule, logging swap requests instead of relying on memory, and keeping a record of who said what if a dispute over the existing order ever needs to go back in front of the court. That's the gap OnePage is built for, alongside whatever schedule your parenting plan lands on.
