Custodial Interference in California: Penalties and Defenses

Custodial interference in California is a crime under Penal Code sections 278 and 278.5, and it covers more than physically taking a child across state lines. Maliciously hiding a child, refusing to return one at the scheduled exchange, or blocking the other parent’s court-ordered contact can all qualify. The offense is a wobbler, meaning prosecutors can charge it as a misdemeanor punishable by up to a year in county jail or as a felony carrying up to four years in state prison, and family court penalties often follow on a separate track.

What Counts as Custodial Interference

California splits the offense into two statutes based on who is doing the interfering.

Penal Code 278 applies to someone with no custody rights at all: a parent whose rights were terminated, a grandparent, a new partner, or anyone else who maliciously takes, entices, keeps, or conceals a child from the lawful custodian.¹ A genuine misunderstanding about pickup times would not qualify because the statute requires malicious intent.

Penal Code 278.5 is the statute that shows up in most co-parenting disputes. It applies when someone who does hold custodial or visitation rights deprives the other parent of theirs.² You don’t have to leave the state. Refusing to hand the child over at a scheduled exchange, hiding the child’s whereabouts, or cutting off court-ordered phone and video contact can all be enough. Malicious intent is required here too.

Criminal Penalties

Both statutes are wobblers, so the same underlying conduct can lead to very different outcomes depending on how a prosecutor charges it. The felony ranges differ between the two sections.

A conviction under Section 278, for someone without custody rights, carries up to one year in county jail and a fine up to $1,000 as a misdemeanor, or two, three, or four years in state prison and a fine up to $10,000 as a felony.¹

A conviction under Section 278.5, for a parent or guardian who does have some custody rights, carries the same misdemeanor range but a shorter felony sentence: 16 months, two years, or three years in state prison, with a fine up to $10,000.²

Prosecutors weigh how long the child was withheld, whether the parent tried to conceal the child’s location, whether the child faced physical danger, and the emotional impact on the child and the other parent when deciding whether to file the case as a misdemeanor or a felony. A conviction under either section also feeds directly into future custody decisions, because courts must consider each parent’s history when deciding what serves the child’s best interest.³

Family Court Consequences

Criminal prosecution isn’t the only path, and it’s often not the fastest. A parent whose custody or visitation rights have been violated can pursue several remedies in family court that run separately from anything happening on the criminal side.

Contempt of Court

A custody order carries the force of law, and willfully disobeying one can lead to a contempt finding.⁴ Under Code of Civil Procedure 1218, contempt is punishable by a fine of up to $1,000, up to five days in jail, or both, and the court can order the violating parent to pay the other side’s reasonable attorney’s fees and costs from the proceeding.⁵ Contempt is a high bar because it requires proof that the other parent deliberately disobeyed a clear order, but it’s one of the strongest tools available.

Custody Modification

Repeated interference is grounds to ask the court to change custody. California courts can modify custody orders at any time when the change serves the child’s welfare.⁶ Among the factors the court weighs is which parent is more likely to encourage frequent contact with the other parent.⁷ A documented pattern of interference cuts against the interfering parent on that factor, and the result can be reduced parenting time or a shift to supervised visitation.

Reimbursement of Costs

Interference often generates real expenses for the affected parent, from travel to recover a child to emergency legal filings to missed work. A parent can seek reimbursement for those costs through family court. Separate civil claims for emotional distress are possible but require stronger proof of severe harm and intentional wrongdoing.

Defenses That Can Apply

A charge isn’t a conviction. California recognizes several defenses to custodial interference, and each has strict requirements.

Protecting the Child From Immediate Harm

Penal Code 278.7 is the strongest statutory defense. A parent with custody rights who had a good-faith, reasonable belief that leaving the child with the other parent would result in immediate physical injury or emotional harm has not committed a crime under Section 278.5.⁸ The exemption also covers parents who are domestic violence victims and reasonably believe the child faces harm.

The defense only works if the parent takes all of these steps:

Within 10 days of withholding the child, file a report with the district attorney’s office in the county where the child previously lived, giving your name, current address and phone number, the child’s location, and the reasons for your actions.
Within 30 days, begin a custody proceeding in a court with proper jurisdiction.
Notify the DA’s office of any changes to your address or phone number.

Missing any of these steps can destroy the defense. Courts also look for objective support for the belief of danger, like medical records, police reports, or witness statements, rather than speculation.⁸

Consent to the Schedule Change

If the other parent agreed to a deviation from the custody schedule, there’s no interference. Proving consent is the hard part. Courts give weight to text messages, emails, or written exchanges confirming the change. A purely verbal agreement rarely defeats a charge when the other parent denies it.

Ambiguity in the Order

When the custody order itself is unclear about the time, location, or conditions of a particular exchange, a parent can argue they reasonably read it differently instead of deliberately violating it. This works when the ambiguity is obvious on the face of the order. It does not work when a parent is stretching a clear provision.

Military Deployment

The federal Servicemembers Civil Relief Act protects active-duty parents. A servicemember who receives notice of a custody proceeding during deployment can request a stay of at least 90 days, and any temporary custody order based solely on the deployment must expire when the deployment ends.⁹ Courts cannot treat deployment alone as a reason to permanently modify custody. A parent who misses exchanges because of military orders is in a different position than one who simply refuses to comply.

What to Do Instead of Withholding a Child

The single biggest mistake parents make is adjusting the custody arrangement on their own when the current schedule stops working. A custody order cannot be modified unilaterally. If circumstances change, whether because of a job relocation, a new school schedule, or a safety concern, the parent who wants the change must file a motion and show the modification serves the child’s best interest.³ Until a judge signs a new order, the existing one controls. Acting first and asking permission later is how parents end up charged under Penal Code 278.5.

Every California custody and visitation order must state each parent’s rights, the basis for the court’s jurisdiction, and a warning that violating the order can trigger civil or criminal penalties.¹⁰ That warning exists so no parent can credibly claim they didn’t know the order was enforceable.

When a Child Is Taken Across State or National Lines

Taking a child out of California raises the stakes and pulls in federal law. The Parental Kidnapping Prevention Act requires every state to honor a custody order from another state when the issuing court had proper jurisdiction, which stops a parent from fleeing to a new state and seeking a competing order there. California has also adopted the Uniform Child Custody Jurisdiction and Enforcement Act, in Family Code section 3400 and following, which sets rules for which state has authority and how to enforce out-of-state orders here.

When a child is taken from the United States or kept abroad, federal criminal law applies. Under 18 U.S.C. 1204, removing a child from the country or retaining a child outside the country with intent to obstruct the other parent’s custodial rights is a federal felony punishable by up to three years in prison.¹¹ For countries that have signed the Hague Convention on International Child Abduction, the International Child Abduction Remedies Act lets a left-behind parent petition federal court for the child’s return to their country of habitual residence.¹² Those proceedings move quickly and focus on jurisdiction, not on who should ultimately have custody.

If you’re worried the other parent may try to remove your child from the country, the U.S. Department of State runs the Children’s Passport Issuance Alert Program, which notifies you when someone applies for a U.S. passport for your child.¹³ The program cannot block a foreign passport or stop travel on a passport the child already holds. California courts can order passport surrender and restrict international travel as part of a custody order when there’s a risk of abduction.¹⁰
