Custodial interference in California is a crime: under Penal Code sections 278 and 278.5, maliciously taking, hiding, or withholding a child from a person with lawful custody can be charged as a misdemeanor or a felony, and it can cost the offending parent custody as well. Which section applies depends on whether the person has any custody rights to begin with, and the penalties follow from there.
What Counts as Custodial Interference
California splits the offense into two statutes based on who the accused is.
Penal Code 278 applies to a person with no custody rights at all. That includes a parent whose rights have been terminated, a grandparent, a new partner, or anyone else who maliciously takes, hides, or refuses to return a child in order to keep that child away from the lawful custodian.1California Legislative Information. California Code PEN 278 – Child Abduction
Penal Code 278.5 is the statute that usually surfaces in co-parenting disputes. It covers anyone who has some custodial or visitation rights but deprives the other parent of theirs.2California Legislative Information. California Code PEN 278.5 – Child Abduction You don’t need to leave the state. Refusing to hand the child over at the scheduled exchange, concealing where the child is, or blocking court-ordered phone or video contact can each be enough. Both statutes require malicious intent, so a genuine mix-up over pickup times is not the offense.
Virtual visitation deserves a mention because parents sometimes assume it is informal. When a judge writes video calls, phone calls, or similar electronic contact into a custody order, those provisions are enforceable just like an in-person handoff. A parent who routinely blocks calls or cuts off scheduled video time is exposed to the same enforcement as a parent who refuses an exchange at the door.
Criminal Penalties
Both offenses are wobblers, meaning prosecutors can file them as a misdemeanor or a felony. The misdemeanor range is the same under either section; the felony ranges differ.
Under Penal Code 278, a conviction 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.1California Legislative Information. California Code PEN 278 – Child Abduction
Under Penal Code 278.5, the misdemeanor range matches: up to one year in county jail and up to a $1,000 fine. The felony term is shorter, 16 months, two years, or three years in state prison, with a fine up to $10,000.2California Legislative Information. California Code PEN 278.5 – Child Abduction
Prosecutors look at how long the child was withheld, whether the parent concealed the child’s location, whether the child was exposed to physical danger, and the emotional impact on the child and the other parent when deciding charge level. A conviction also feeds into any future custody proceeding, because courts weighing custody must consider each parent’s history, and a child-abduction conviction is hard to argue past.3California Legislative Information.

Civil and Family-Court Consequences
Criminal charges are not the only path. A parent whose custody or visitation has been violated often gets a faster, more practical result through the family court.
Contempt of Court
A custody order carries the force of law, and willfully disobeying one can result in a contempt finding.4California Courts. Enforce a Custody Order Under California Code of Civil Procedure 1218, a parent found in contempt faces a fine up to $1,000, up to five days in jail, or both, and the court can order the violating parent to pay the other parent’s reasonable attorney’s fees and costs.5California Legislative Information. California Code CCP 1218 – Of Contempts The bar is high because you must show the other parent deliberately disobeyed a clear order, but it is one of the strongest tools available.
Custody Modification
When interference becomes a pattern, the affected parent can ask the court to change the arrangement. California courts can modify custody at any time when doing so serves the child’s welfare.6California Legislative Information. California Code FAM 3022 – General Provisions Among the factors judges weigh is which parent is more likely to encourage frequent contact with the other.7California Legislative Information. California Code FAM 3040 – Order of Preference for Custody A documented history of interference pushes directly against that factor and can produce reduced parenting time or supervised visitation.
Reimbursement of Costs
Interference generates real expenses: travel to recover a child, emergency filings, missed work. A parent can seek reimbursement for those costs through the family court.
Defenses
A charge does not mean a conviction. California recognizes several defenses, each with strict requirements.
Protecting the Child From Harm
Penal Code 278.7 is the strongest statutory defense. If a parent with custody rights had a good-faith, reasonable belief that leaving the child with the other parent would cause immediate physical injury or emotional harm, withholding the child is not a crime under Section 278.5.8California Legislative Information. California Code PEN 278.7 – Exemption for Custodial Interference The statute also specifically covers domestic violence victims who reasonably believe the child is in danger.
The defense depends on following every step the statute requires:
- Within 10 days of withholding the child, file a report with the district attorney’s office in the county where the child previously lived, including your name, your 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 step can destroy the defense. Courts also examine whether the belief of danger was objectively reasonable, supported by medical records, police reports, or witness statements rather than speculation.
Consent
If the other parent agreed to a deviation from the schedule, there is no interference. Proving it is the hard part. Judges give far more weight to this defense when the parent can produce texts, emails, or a written exchange confirming the change. A purely verbal agreement rarely defeats a charge once the other parent denies ever consenting.
An Ambiguous Order
Older custody orders sometimes fail to address new circumstances like a relocation or a changed school schedule. If the order is genuinely unclear about the time, location, or conditions of an exchange, a parent can argue reasonable interpretation rather than willful violation. The defense works when the ambiguity is obvious on the face of the order, not when a parent is stretching clear language.
Military Deployment
Under the Servicemembers Civil Relief Act, an active-duty servicemember who receives notice of a custody proceeding during deployment can request a stay of at least 90 days. A temporary custody order issued solely because of deployment must expire when the deployment ends, and courts may not treat deployment as the sole basis for permanently modifying custody.9Office of the Law Revision Counsel. 50 USC 3938 – Child Custody Protection A deployed parent who misses exchanges because of military orders is not in the same position as a parent who simply refuses to comply.
When the Child Is Taken Across State or National Lines
Crossing a border raises the stakes and brings federal law into play.
Interstate Cases
The federal Parental Kidnapping Prevention Act requires every state to honor and enforce a custody order from another state when the issuing court had proper jurisdiction. The PKPA does not create criminal penalties itself; it prevents a parent from fleeing to another state and asking that state’s courts for a competing order. California has also adopted the Uniform Child Custody Jurisdiction and Enforcement Act, codified at Family Code 3400 and following, which sets the rules for which state has authority and provides the process for enforcing an out-of-state order in California.
International Cases
Under 18 U.S.C. 1204, removing a child from the United States or keeping a child abroad with the intent to block the other parent’s custodial rights is a federal felony punishable by up to three years in prison.10Office of the Law Revision Counsel. 18 USC 1204 – International Parental Kidnapping
When the destination country has signed the Hague Convention on International Child Abduction, the left-behind parent can file a petition in federal court under the International Child Abduction Remedies Act seeking the child’s return to the country where the child was living before the abduction.11Office of the Law Revision Counsel. 22 USC 9001 – Findings and Declarations These cases move quickly and focus on which country has jurisdiction, not on who should ultimately have custody.
Passport Prevention
If you are worried the other parent may try to take your child abroad, the U.S. Department of State runs the Children’s Passport Issuance Alert Program. Enrollment is free and alerts you whenever anyone applies for a U.S. passport for your child.12U.S. Department of State. Children’s Passport Issuance Alert Program Parents, legal guardians, attorneys, law enforcement, and courts can request enrollment with Form DS-3077 and proof of identity and legal relationship to the child. The program cannot block a foreign passport and cannot physically stop travel if a valid passport already exists. California courts can order passport surrender and restrict international travel as part of a custody order when there is a risk of abduction.13California Legislative Information. California Code FAM 3048 – Child Custody and Visitation Order Requirements
What To Do Instead of Changing Things on Your Own
The single biggest mistake parents make is adjusting the custody arrangement unilaterally when the current schedule stops working. A custody order cannot be changed by agreement alone or by one parent’s decision. If something has changed, whether a job relocation, a new school schedule, or a safety concern, file a motion and ask the court to modify the order based on the child’s best interest.3California Legislative Information. California Code FAM 3011 – Best Interests of the Child Until a judge signs a new order, the existing one controls. Acting first and asking later is how parents end up charged under Penal Code 278.5.
When the other parent refuses to return the child, law enforcement can enforce a custody order at the scene if the order is clear and the violation is obvious. Keep a certified copy of the order accessible. If the child has been concealed or moved to an unknown location, the matter escalates into a missing-child investigation. Courts can also designate neutral exchange locations or require supervised exchanges when past conflict makes direct handoffs risky.
