Child custody in Los Angeles County is decided by the Superior Court’s Family Law Division, which sets both where your child lives and who makes the major decisions about the child’s upbringing.1Superior Court of Los Angeles County. Family Law Every ruling turns on one question: what arrangement best protects the child’s health, safety, and welfare. The path to a final order runs through specific forms, mandatory mediation, and, if needed, a hearing before a judge. Married and unmarried parents file different petitions, but from mediation onward the process is largely the same.
Legal Custody and Physical Custody
California treats custody as two separate rights that can be shared or held alone in any combination. Legal custody is the authority to make important decisions about your child’s education, healthcare, and general welfare.2California Legislative Information. California Code Family Code 3003 Physical custody is about where the child actually lives. When physical custody is shared, the schedule has to give each parent enough time to maintain a meaningful, ongoing relationship with the child.3California Legislative Information. California Code Family Code 3004
A judge can mix these however the situation requires. Joint legal custody with primary physical custody to one parent is common: both parents decide together on schools and doctors, but the child lives mostly in one home with a set visitation schedule for the other. Joint legal and joint physical custody splits both. Sole custody of either type is available when sharing would not work for the child.
How a Judge Decides: The Best Interests Standard
Every custody ruling in California applies the “best interests of the child” standard. The factors the court weighs include:4California Legislative Information. California Code FAM 3011
- The child’s health, safety, and welfare.
- Any history of abuse by a parent against the child, the other parent, or other household members.
- Ongoing illegal drug use, alcohol abuse, or prescription misuse by either parent. The court may require independent proof before weighing these allegations.
- The child’s frequent, continuing contact with both parents, which California policy favors unless contact would harm the child.3California Legislative Information. California Code Family Code 3004
Judges are not limited to that list. They regularly look at each parent’s willingness to cooperate, the stability of each home, and which parent has been the child’s primary caretaker.
Filing a Custody Case
Your starting form depends on your relationship history with the other parent. If you were married or in a registered domestic partnership, custody is decided inside your divorce or separation case, which begins with a Petition for Marriage or Domestic Partnership (Form FL-100).5Judicial Council of California. FL-100 Petition – Marriage/Domestic Partnership If you were never married, you file a Petition to Establish Parental Relationship (Form FL-200), which asks the court to identify both legal parents and set custody and visitation in the same case.6California Courts. Petition to Determine Parental Relationship FL-200
Either way, you also file a Declaration Under the Uniform Child Custody Jurisdiction and Enforcement Act (Form FL-105). It asks you to list every place your child has lived for the past five years and the people the child lived with during each of those periods.5Judicial Council of California. FL-100 Petition – Marriage/Domestic Partnership The court uses this to confirm it has authority over the case and to check for other custody proceedings. Missing or inaccurate information here can delay everything.
The filing fee for a new family law petition in Los Angeles County is $435.7Superior Court of California, County of Los Angeles. Civil Fee Schedule If you cannot afford it, you can ask the court to waive the fee by filing a Request to Waive Court Fees (Form FW-001), which is available if you receive public benefits, have low income, or lack enough income to cover both basic needs and court costs.8California Courts. Request to Waive Court Fees
Once the clerk assigns a case number, you have to arrange for the other parent to be formally served with copies of what you filed, along with a Summons (Form FL-110). You cannot hand the papers over yourself. The person who serves them completes a Proof of Service of Summons (Form FL-115), which the court needs on file before a hearing can go forward.
Mediation Through Family Court Services
Before parents ever see a judge on a contested custody issue, Los Angeles County offers an online step. The Family Law Online Dispute Resolution Program walks both parents through questions designed to produce a proposed parenting plan that can be submitted to the court for approval.9Superior Court of Los Angeles County. Child Custody Mediation If the online program does not produce an agreement, mediation through Family Court Services is next, and it is required whenever custody or visitation is contested.10California Legislative Information. California Code FAM 3170
In Los Angeles County this mediation is called Child Custody Recommending Counseling, and a neutral mental health professional runs the session. Come ready to talk about school-week schedules, weekends, holidays, summer breaks, and transportation between homes.
The word “recommending” carries weight. If you reach agreement in the session, the counselor helps draft a written parenting plan for the judge to sign. If you cannot agree, the counselor sends the judge a report with custody recommendations.9Superior Court of Los Angeles County. Child Custody Mediation Judges give those recommendations substantial weight because the counselor spoke with both parents and saw the family dynamics directly. This session is your best chance to shape the outcome before a judge decides for you.
The Court Hearing
If mediation does not fully resolve the case, it goes to a hearing before a family law judge. The judge reviews what is already on file: your declarations, the mediation counselor’s report, and any other evidence. Both parents can present testimony, call witnesses, and respond to the other side. Expect direct questions about proposed schedules, work situations, and the child’s needs.
After hearing the evidence, the judge issues a ruling that becomes a written custody order spelling out each parent’s legal and physical custody rights, the visitation schedule, and any special conditions. That order carries the full force of law.
Emergency Custody Orders
When a child faces immediate danger, the standard timeline is too slow. California allows a parent to request emergency temporary orders (called ex parte orders) without waiting for a full hearing, but only on a showing of immediate harm to the child or an immediate risk that the other parent will take the child out of California.11Judicial Council of California. FL-305 Temporary Emergency Ex Parte Orders “Immediate harm” includes recent domestic violence or a continuing pattern of violence.
You file a Request for Order (Form FL-300) together with Temporary Emergency Orders (Form FL-305), explaining why waiting for a regular hearing would put the child at risk. Courts typically hear these requests within one to two business days. If granted, the emergency order is temporary and stays in place only until a full hearing where both parents can present their side.
When Domestic Violence Is in the Picture
Domestic violence changes the default. If the court finds a parent committed domestic violence within the past five years against the other parent, the child, or the child’s siblings, California law presumes that giving custody to that parent would harm the child.12California Legislative Information. California Code Family Code 3044 The parent who committed the violence has to affirmatively prove that custody would still serve the child’s best interests, and the usual preference for contact with both parents cannot be used to overcome the presumption. In most cases where it applies, the non-abusive parent receives sole legal and physical custody, and the other parent’s time with the child is limited or supervised.
Supervised Visitation
When a judge has concerns about safety during visits but does not want to cut contact off, the court can order supervised visitation. This often happens where a restraining order is in place, and the court weighs how serious the conduct behind the order was, how much time has passed, and whether the restrained parent has committed further abuse.13California Legislative Information. California Code FAM 3100 Virtual visitation through video calls is available when in-person supervised visits are not practical.
The supervisor can be a trained professional monitor or a nonprofessional the parents know, typically a friend or family member. A nonprofessional monitor cannot have a history of child abuse, molestation, or violent crimes, and cannot have been on probation or parole in the past ten years.14California Courts. Nonprofessional Providers of Supervised Visitation Professional monitors have specialized training and charge for their time. The order specifies which type is required and whether the monitor can end a visit if something goes wrong.
The Child’s Preference
California law requires the court to consider a child’s wishes if the child is old enough and mature enough to express a meaningful preference. There is no set age below which a younger child is automatically excluded; the judge has discretion.15California Legislative Information. California Code Family Code 3042
At age 14, the rule sharpens. A child who is 14 or older and wants to speak to the judge about custody must be allowed to do so, unless the judge finds that testifying would harm the child and puts those reasons on the record.15California Legislative Information. California Code Family Code 3042 Courts generally do not have the child speak in front of both parents. The judge often meets with the child privately or receives the child’s input through the mediator or a custody evaluator. A child is never required to state a preference, and the judge keeps final authority over the decision.
Moving With Your Child After an Order
Moving after a custody order is in place triggers a notice obligation. If the order includes a relocation provision, the relocating parent must notify the other parent at least 45 days before the planned move by certified mail, with a copy to the other parent’s attorney if there is one.16California Legislative Information. California Code Family Code FAM 3024 The 45-day window exists to give both parents time to mediate and negotiate a revised schedule.
If you cannot agree, either parent can ask the court to modify the order. The relocating parent does not automatically get to take the child. The court applies the same best-interests analysis and looks at the reason for the move, the child’s ties to the current community, and whether a workable visitation schedule with the non-moving parent is still possible. Moving without proper notice can seriously damage your credibility with the judge.
Changing an Existing Custody Order
Custody orders are not permanent. Either parent can ask the court to modify the arrangement when circumstances change significantly. For joint custody orders, the court can modify or end the arrangement when the child’s best interests require a change.17California Legislative Information. California Code FAM 3087-3089 Common reasons include a parent’s relocation, a major work-schedule change, substance abuse, the child’s changing needs as they grow, or a parent consistently ignoring the current order.
To start, file a Request for Order (Form FL-300) explaining what you want changed and why. The case goes through mediation again, and if the other parent objects, the court holds a hearing and reapplies the best-interests standard, this time also examining what has actually changed since the last order. Being unhappy with the current arrangement is not enough. You have to point to something concrete that is different from when the judge last ruled.
