A parenting plan in California is a written court order under California Family Code § 3040 that sets out legal custody, physical custody, and a parenting time schedule for your children. As of March 2026 the custody/divorce filing fee is $435, courts require mandatory mediation under Family Code § 3170 before any contested hearing, and every plan must serve the child's best interest.

What Is a Parenting Plan in California?
A parenting plan California families file is a written agreement, signed into a court order, that describes where the children live, when they see each parent, and how parents share decisions. Under Cal. Fam. Code § 3040, the court has wide discretion to approve any plan that serves the child's best interest, with no preference for joint or sole custody.
A complete parenting plan covers two distinct types of authority. Legal custody is the right to make important decisions about health care, education, and welfare. Physical custody determines who the children live with and follows a parenting time schedule. Each type can be awarded jointly to both parents or solely to one. Most California parents share joint legal custody so both stay involved in major decisions, while physical custody arrangements vary widely based on work schedules, distance between homes, and the children's ages. A well-drafted custody agreement removes ambiguity, which reduces future conflict and the need to return to court.
The plan becomes enforceable only when a judge signs it. Until then, an informal schedule between parents carries no legal weight, and either parent can change the arrangement. Once the judge signs the order, both parents must follow it exactly, and violations can lead to contempt proceedings or a custody modification.
The Best Interest of the Child Standard
California courts decide every custody question using the best interest of the child standard under Cal. Fam. Code § 3011 and § 3020. The court weighs the child's health, safety, and welfare; the quality of each parent's relationship with the child; and any history of abuse. The standard governs 100% of custody determinations and overrides any agreement that harms the child.
The statute does not give a rigid checklist. Instead, Fam. Code § 3011 directs the court to consider the health, safety, and welfare of the child; the nature and amount of contact with both parents; and any history of abuse by a parent against the child, the other parent, or another household member. Under § 3011(b), even one documented incident of abuse can shift a custody decision. Section 3020 declares it California public policy to ensure children have frequent and continuing contact with both parents, except where that contact is not in the child's best interest because of safety concerns such as domestic violence or substance abuse.
The court also evaluates which parent is more likely to support the child's relationship with the other parent. This is often called the friendly parent factor. A parent who interferes with the other parent's parenting time, or who repeatedly disparages the other parent, risks losing custody. The law specifically protects against bias: Fam. Code § 3040 bars courts from considering a parent's sex, gender identity, gender expression, sexual orientation, or immigration status when deciding custody.
Types of Custody and Time-Share Schedules
California recognizes four custody combinations: joint legal, sole legal, joint physical, and sole physical custody, all defined under Cal. Fam. Code § 3040. Most parents share joint legal custody, while the physical custody schedule, called the parenting time schedule, sets the day-to-day living arrangement. There is no fixed minimum percentage; the court approves any time-share that fits the child's best interest.
The table below compares common co-parenting schedule structures California families use. Each schedule reflects a different approximate time-share split, and the right choice depends on the children's ages, the distance between homes, and each parent's work commitments.
| Schedule Type | Approximate Split | Best Fit |
|---|---|---|
| Alternating weeks (7/7) | 50/50 | School-age children, parents living close together |
| 2-2-3 rotation | 50/50 | Younger children needing frequent contact with both parents |
| Every other weekend | About 80/20 | One parent has the primary home, the other has visitation |
| 5-2 (weekdays/weekends) | About 70/30 | One parent handles school weeks, the other takes weekends |
| Supervised visitation | Varies | Safety concerns, reunification, or substance-abuse history |
A detailed parenting time schedule should also assign holidays, school breaks, birthdays, and summer vacation. Many California plans alternate major holidays by year, split summer into blocks, and set exchange times and locations to minimize conflict. The more specific the visitation schedule, the less room for disputes later.
Mandatory Custody Mediation in California
California requires mediation before any contested custody hearing under Cal. Fam. Code § 3170. When a petition shows that custody or visitation is contested, the court clerk must set the matter for mediation, which takes place before the judge hears the case. Court-based mediation through Family Court Services is generally free, as Fam. Code § 3160 requires every county family court to provide a mediator.
The purpose of mediation is to help parents build a workable co-parenting schedule and reduce conflict before a contested hearing. Mediation is typically scheduled one to two weeks before the court date. Mediators hold at least a master's degree in psychology, counseling, or a related field, with extensive clinical experience. If parents reach agreement, the mediator drafts a written parenting plan, both parents review and sign it as a stipulation, and the judge can sign it into a court order.
Counties handle mediation in two different ways, and the distinction matters. In confidential counties, if parents do not agree, the mediator files no report and the parties argue the disputed issues before the judge. In recommending counties such as San Diego and Stanislaus, the Child Custody Recommending Counselor may submit written recommendations to the judge under Cal. Fam. Code § 3183. If you disagree with a recommendation, you may request a continuance, and under Fam. Code § 217 you can require oral testimony, including cross-examining the counselor. Where domestic violence is alleged, parents receive separate mediation appointments for safety.
Filing Your Parenting Plan: Forms and Fees
The cost to start a California case that includes a parenting plan is $435 as of March 2026, paid when you file. A traditional dissolution begins with Form FL-100, and custody requests are made on Form FL-300 (Request for Order) with the proposed parenting plan attached. As of March 2026. Verify with your local Superior Court clerk before filing.
A traditional filing requires the petitioner to pay $435, and if the other spouse files a Response, that adds a second $435 fee, totaling $870 in court costs. A major 2026 change reduces this expense. Under Senate Bill 1427, effective January 1, 2026, couples who agree on all terms can file jointly using new Form FL-700, the Joint Petition for Dissolution. Because the joint filing counts as service on both spouses, there is no separate service of process and no second filing fee, cutting total court costs from $870 to $435. This option is available to all agreeing couples regardless of marriage length, children, or asset complexity.
Low-income filers can avoid the fee entirely. A fee waiver is available using Judicial Council Form FW-001 for households at or below 125% of federal poverty guidelines. With a traditional FL-100 filing, you must also formally serve your spouse, which typically costs $50 to $100 through a process server or sheriff. Certified copies of the final judgment cost about $15 plus $0.50 per page at most California courts. Verify all amounts with your local clerk before filing.
California Residency and Timeline Requirements
To obtain a divorce judgment that includes your parenting plan, California requires that one spouse has lived in the state for 6 months and in the filing county for 3 months under Cal. Fam. Code § 2320. The combined residency and cooling-off rules mean the fastest possible divorce takes 6 months and 1 day from the date the respondent is served or appears.
Only one spouse needs to meet the residency requirement, and you can file in the county where either of you has lived for three months even if you live in different counties. If neither spouse meets the residency rule yet, you can file for legal separation, which has no residency requirement, then convert it to a dissolution under Cal. Fam. Code § 2321 once you qualify. A special rule under § 2320(b) allows same-sex couples who married in California but live where no court will dissolve their marriage to file in the county where they married.
The 6-month minimum comes from the mandatory cooling-off period in Cal. Fam. Code § 2339, which bars a judgment until at least six months after the respondent was served or appeared. Custody and parenting time orders, however, can be made much sooner. A parent can request temporary custody orders on Form FL-300 early in the case, and the court can issue a temporary parenting plan within weeks while the divorce proceeds.
2026 Changes Affecting California Parenting Plans
Several 2026 California laws affect how parents build and protect parenting plans. The headline change, Senate Bill 1427, cut joint-petition court costs from $870 to $435 starting January 1, 2026. Two other January 1, 2026 laws, the Family Preparedness Plan Act and SB 343, expanded guardianship planning and child-support review requirements.
The Family Preparedness Plan Act (AB 495), effective January 1, 2026, allows parents to name temporary guardians for their children without losing their own parental rights. This is especially relevant for families building contingency provisions into a parenting plan for emergencies, deployment, or immigration concerns. Senate Bill 343, also effective January 1, 2026, created enhanced requirements for child support agencies to review each parent's earning capacity, which can affect support calculations that accompany a custody order.
Courts in 2026 also expect more detailed plans. The drafting baseline has shifted toward granular, safety-conscious provisions that address decision-making authority, parent-to-parent communication, and schedules that adapt as children grow. For relocation, the framework from In re Marriage of Burgess (1996) and In re Marriage of LaMusga (2004) still controls move-away analysis, weighing the reason for the move, the distance, and the impact on the child's relationship with each parent.
Modifying a California Parenting Plan
A California parenting plan can be modified when there has been a significant change in circumstances that affects the child's best interest under Cal. Fam. Code § 3040. You request a change by filing Form FL-300, and contested modification requests must go back through mandatory mediation under Fam. Code § 3170. The court applies the same best-interest standard it used for the original order.
For a final custody order, California courts generally require a substantial change in circumstances before changing the parenting arrangement. Examples include a parent relocating, a change in a child's school or medical needs, a parent's work schedule shifting, or evidence of abuse or neglect. Minor scheduling adjustments that both parents agree to can often be filed as a stipulation and signed by the judge without a contested hearing. When parents disagree, the case returns to mediation first, then to the judge if mediation does not resolve it.
Until a judge signs a modified order, the existing parenting plan remains fully enforceable. Parents should never stop following the current order based on a verbal agreement alone, because an unsigned change has no legal effect and can lead to enforcement problems. Document every agreed change in writing and submit it to the court to keep your custody agreement enforceable.
