How long does it take to modify a custody order in California?

The clerk writes a hearing date on your Form FL-300 at filing, often several weeks to a few months out depending on the county. Contested cases add mediation or child custody recommending counseling before the hearing (Family Code 3170), and a contested move away request commonly takes longer still.

Can a California parent move away with the child after a custody order?

Family Code 7501 gives a parent entitled to custody a right to change the child's residence, subject to the court's power to restrain a removal that would prejudice the child. The Judicial Council guide explains that sole physical custody and joint physical custody are treated differently on a contested move.

Do I need the other parent to agree to change custody in California?

No. Either parent can file Form FL-300 alone, and the other parent is served and may respond. If you both agree, you can submit a written stipulation for a judge to sign instead of litigating. The judge still measures any agreement against the child's best interest.

At what age does a California judge have to hear the child's wishes?

Family Code 3042 says a child 14 or older who wishes to address the court about custody or visitation must be permitted to, unless the court finds that is not in the child's best interest and states its reasons. Any child old enough to form an intelligent preference has it weighed.

Do I have to go to mediation before a California custody hearing?

Usually yes. Family Code 3170 directs the court to set contested custody or visitation issues for mediation when the pleading shows they are contested, and many counties use child custody recommending counseling, where the counselor sends the judge a recommendation. Domestic violence cases follow a separate Judicial Council protocol.

What happens if a California parent just stops following the custody order?

Ignoring a custody order is an enforcement problem, not a modification, and it exposes the parent to contempt and to an unfavorable change. Family Code 3047 does protect a parent whose absence follows military activation, saying that alone cannot justify modification. Keep following the current order until a judge changes it.

Can a California court keep deciding custody after the child moves out of state?

Family Code 3422 gives the California court that made the order exclusive continuing jurisdiction until the significant connection test fails, or until a court finds the child, both parents, and any person acting as a parent no longer reside here. Talk to a lawyer before an interstate move.

How to Modify Child Custody in California

Reviewed by DocDraft Legal Team · California · Last updated October 7, 2026

California puts no clock between you and a custody motion, so the question is never how long you have waited. Modifying child custody here means asking the superior court that issued your existing custody or parenting time order to change it because something significant has changed since that order was made. Family Code 3022 lets a judge make a custody order at any time after the last one, and no section of the Family Code imposes a waiting period or a time bar. The real gate is judicial doctrine rather than statute. Once a custody order is final, the changed circumstance rule requires the parent asking for a change to show a significant change of circumstances, and that the new arrangement serves the child's best interest under the Family Code 3011 factors. You start with the Request for Order, Judicial Council Form FL-300, a mandatory statewide form, filed into the same case number as the order you want changed, with the optional Form FL-311 for schedule detail. The statewide filing fee is $60 under Government Code 70617, and a fee waiver is available on Form FW-001. Expect one procedural detour that catches parents out: Family Code 3170 sends contested custody and visitation modifications to mediation or child custody recommending counseling before you see the judge. If a move is involved, read your own order, because under Family Code 3024 the 45 day notice figure and any distance limit are order terms, not general statutes. Keep following your current order until a judge changes it. Attorney review of your filing is available through DocDraft.

What is prompting the change to your custody order?

DocDraft provides document preparation, not legal advice.

How do I modify a child custody order in California?

File a Request for Order, Judicial Council Form FL-300, in the superior court that issued your order, using the same case number. Explain what has changed since the judge made the last order, attach supporting documents, and the clerk writes your hearing date on the form. A $60 filing fee applies (Cal. Government Code 70617).

Is there a waiting period to modify custody in California?

No. California imposes no waiting period or time bar before a parent may ask to change a custody or parenting time order; Family Code 3022 allows a new order at any time after the last one. The substantive hurdle is showing a significant change of circumstances since that order.

How much notice must a California parent give before moving with a child?

California sets no statewide statutory notice period. Family Code 3024 lets the judge write a notice term into the custody order, triggered by a planned change of the child's residence for more than 30 days, with notice given at least 45 days ahead where feasible. Read your own order.

Which court changes a custody order in California?

The Superior Court of California in the county that made the order, through its family law department, which keeps exclusive continuing jurisdiction under Family Code 3422. Contested custody and visitation modifications are set for mediation or child custody recommending counseling before the hearing (Family Code 3170).

California custody modification at a glance

Changing child custody in California means asking the superior court that issued your existing custody or parenting time order to change it because something significant has changed since then. California adds no waiting period: Family Code 3022 lets a judge make a custody order at any time after the last one. The real gate is judicial doctrine rather than statute. Once a custody order is final, the changed circumstance rule requires the parent asking for a change to show a significant change of circumstances, and that the new arrangement serves the child's best interest under the Family Code 3011 factors. Procedurally California is unusual in two ways. It prescribes one mandatory statewide charging form, the Request for Order (Form FL-300), and it sends every contested custody or visitation modification to mediation or child custody recommending counseling before the parent ever sees the judge (Family Code 3170).

A California schedule change eight months after judgment

Suppose a California judgment eight months old gives you alternating weekends, and your child just turned 14 and wants more weekday time to stay near a new school program. Nothing stops you from filing now, because California sets no waiting period, but you still need a significant change since that judgment, so you document the school program and the schedule conflict on Form FL-300 item 9. You file into the same case number, pay $60, serve the other parent, and attend child custody recommending counseling. At the hearing you note that Family Code 3042 lets a child 14 or older who wishes to address the court be heard, and the judge weighs that without being bound by it. Attorney review of your filing is available through DocDraft.

Relevant Laws

Cal. Family Code 3022 (custody order at any time)

Provides that the court may, during the pendency of a proceeding or at any time thereafter, make a custody order that seems necessary or proper. This is the authority a parent uses to ask for a change, and it sets no waiting period.

Cal. Family Code 3024 (notice of a planned change in the child's residence)

Lets the court specify in a custody order that a parent notify the other parent of a plan to change the child's residence for more than 30 days, with notice provided within a minimum of 45 days before the move to the extent feasible.

Cal. Family Code 3042 (the child's wishes, and age 14)

Requires the court to consider and give due weight to the wishes of a child able to form an intelligent preference, and provides that a child 14 or older who wishes to address the court on custody or visitation shall be permitted to do so unless the court finds otherwise.

Cal. Family Code 3170 (mediation of contested custody and visitation)

Directs that where it appears on the face of a pleading to obtain or modify a temporary or permanent custody or visitation order that custody, visitation, or both are contested, the court shall set the contested issues for mediation.

California Courts self-help: ask for or change a custody and visitation order

The Judicial Council self-help guide walks through the Request for Order (Form FL-300), the Child Custody and Visitation (Parenting Time) Application Attachment (Form FL-311), the published filing fee range, and the mediation step before the hearing.

Regional Variances

California custody modification levers at a glance

Waiting period before you may file

None. Family Code 3022 permits a custody order at any time after the last one, and no Family Code section bars or delays a modification request. There is also no heightened endangerment showing keyed to elapsed time.

Standard to change a final order

The changed circumstance rule, which is California Supreme Court doctrine rather than statutory text: a significant change of circumstances since the final order, plus the child's best interest measured by the Family Code 3011 factors. A joint custody order may be modified under Family Code 3087 where the child's best interest requires it.

Relocation notice

No fixed statewide statutory period. Under Family Code 3024 the court may put a notice term in the order, triggered by a planned change of the child's residence for more than 30 days, with 45 days' notice to the extent feasible. No mileage trigger appears in the custody chapters. Family Code 7501 governs whether a contested move is allowed.

Court

The Superior Court of California for the county that issued the order, family law department, filed into the same case number. Family Code 3422 gives that court exclusive continuing jurisdiction over its own custody determination.

Forms

Request for Order (Form FL-300) is a mandatory Judicial Council form and carries a CHANGE box. Child Custody and Visitation (Parenting Time) Application Attachment (Form FL-311) is optional. Attached Declaration (Form MC-031) handles overflow. Fee waiver is Form FW-001.

Filing fee

$60 statewide under Government Code 70617 for a motion requiring a hearing after the first paper. The Judicial Council self-help guide publishes a $60 to $85 range once local additions are counted, and a higher first paper fee if you have no open case.

Procedural screen

Mediation, not an affidavit. Family Code 3170 sends contested custody or visitation modifications to mediation, and many counties use child custody recommending counseling, where a counselor makes a recommendation to the judge before the hearing.

Child's wishes

Age 14 under Family Code 3042, and what it triggers is a right to address the court if the child wishes to, not a controlling vote. A younger child able to form an intelligent preference still has those wishes considered and given due weight.

Suggested Compliance Checklist

Document the change since your last order

Before you file days after starting

Gather dated proof of what shifted since the judge signed your current order: school records, work schedules, messages, medical notes. A final order is protected by the changed circumstance rule, so the evidence carries the request. Attorney review of your filing is available through DocDraft.

Re-read the notice and distance terms in your judgment

Before any planned move days after starting

Under Family Code 3024 the notice duty and any distance limit are terms a judge may write into your individual order, not general statutes. Find the exact wording in your judgment so you know how many days' notice you owe and what the other parent must do.

Complete the Request for Order (Form FL-300)

As soon as your evidence is assembled days after starting

Fill out the mandatory Judicial Council Form FL-300, check Child Custody and Visitation (Parenting Time) and the CHANGE box, identify the order at item 2(d), and state your facts at item 9. Add Form FL-311 for schedule detail and Form MC-031 if you need more room.

File with the superior court clerk

Promptly, since hearing dates run weeks out days after starting

Bring the original and two copies to the clerk of the superior court that issued your order and use the same case number. Pay the $60 fee set by Government Code 70617, or file Form FW-001 to request a waiver. The clerk writes your hearing date on the form.

Serve the other parent and file the proof

By the court's service deadline days after starting

Have the other parent served with the stamped Request for Order and every attachment, then file the proof of service with the court. Without it on file the judge generally cannot change the order at your hearing.

Attend mediation or child custody recommending counseling

Before your hearing date days after starting

Family Code 3170 sends contested custody and visitation issues to mediation, and many counties use child custody recommending counseling instead. Arrive with a specific written parenting plan proposal, including dates, times, and exchange locations.

Attend the hearing and get the signed order

On your hearing date days after starting

Bring your documents and your proposed schedule. Keep following the existing order right up to the moment the judge signs a new one, because a unilateral departure is an enforcement issue rather than a modification and can count against you.
