California Penal Code 236 defines false imprisonment as the unlawful violation of another person’s personal liberty. In practice, that means intentionally confining, detaining, or restraining someone against their will without legal authority to do so. The offense is a wobbler: it can be charged as a misdemeanor carrying up to a year in county jail, or as a felony carrying 16 months, two years, or three years when the restraint involves violence, menace, fraud, or deceit.
What Counts as False Imprisonment
Prosecutors have to prove two things. The defendant intentionally restrained, confined, or detained another person, and that restraint made the person stay somewhere or go somewhere against their will.1Justia. CALCRIM No. 1240 Felony False Imprisonment
There does not have to be any physical contact. Blocking a doorway counts. Threatening someone who tries to leave counts. Tricking a person into believing they cannot go counts. What the law looks at is whether the person’s freedom of movement was actually restricted and whether they agreed to it.
The restraint also has to be unlawful. Police with a valid warrant, store employees acting within the shopkeeper’s privilege, and parents setting reasonable limits on their children all have authority the law recognizes. Without that authority, even a brief detention can support the charge.
Misdemeanor vs. Felony
The dividing line is how the restraint was carried out. If no force, threats, or deception were involved, the offense is a misdemeanor under Penal Code 237(a). Standing in front of a door to keep someone from leaving a room, or locking a door without any threatening behavior, falls on the misdemeanor side.
The charge becomes a felony when the confinement is accomplished through violence, menace, fraud, or deceit.2California Legislative Information. California Penal Code PEN 237 Each term has a specific meaning:
- Violence means physical force beyond what would be reasonably necessary just to restrain the person. Grabbing and shoving someone into a room, rather than merely blocking the exit, is the classic example.1Justia. CALCRIM No. 1240 Felony False Imprisonment
- Menace is a verbal or physical threat of harm, whether stated outright or implied. Saying “you’ll regret it if you try to leave” qualifies, and so does displaying a weapon.
- Fraud or deceit covers lies and trickery used to keep someone from leaving — for example, telling a person the roads are blocked or that police are waiting outside to arrest them. Prosecutions resting solely on fraud are uncommon.
Penalties
A misdemeanor conviction carries up to one year in county jail, a fine of up to $1,000, or both.2California Legislative Information. California Penal Code PEN 237 Summary probation is also on the table, especially for first-time offenders or cases involving very brief detention.
Felony false imprisonment is punishable under California’s realignment framework by 16 months, two years, or three years in county jail.3California Legislative Information. California Penal Code PEN 1170 The judge picks from this triad based on the facts, any aggravating or mitigating circumstances, and the defendant’s record. The sentence is generally served in county jail rather than state prison unless the defendant has prior convictions for serious or violent felonies, must register as a sex offender, or falls into another disqualifying category under PC 1170(h)(3). A fine of up to $10,000 can be added, along with formal probation that typically runs three to five years with conditions like probation check-ins, community service, or counseling.
Elder and Dependent Adult Victims
When the victim is 65 or older or a dependent adult, the felony triad rises to two, three, or four years under Penal Code 368(f).4California Legislative Information. California Penal Code PEN 368 Caregivers, family members, and institutional staff who confine elderly or dependent adults through force, threats, or deception face this elevated exposure.
Is It a Strike?
Felony false imprisonment is not automatically a strike under California’s Three Strikes law. It does not appear on the list of serious felonies in Penal Code 1192.7(c) or the list of violent felonies in Penal Code 667.5(c). A conviction can still qualify as a strike, though, when the defendant personally inflicted great bodily injury on the victim or personally used a dangerous or deadly weapon, since those circumstances trigger the catch-all provisions of PC 1192.7(c). The distinction matters because a strike doubles the sentence for any future felony.
Defenses That Work in These Cases
Which defense applies depends on who the parties are and how the alleged restraint happened.
Consent
If the person agreed to be confined, there is no false imprisonment. A friend who voluntarily stays in a locked room during a party prank was not falsely imprisoned. The consent has to be genuine. Consent obtained through threats, deception, or from someone too intoxicated or impaired to make a real choice will not hold up.
Lawful Authority
Officers with a valid warrant or probable cause have authority to detain. Private citizens have narrower powers under Penal Code 837: a private person may arrest someone for a public offense committed in their presence, or for a felony even if not personally witnessed.5California Legislative Information. California Penal Code 837 When a citizen’s arrest is lawful, the brief detention that comes with it is not false imprisonment. Get the arrest wrong, though, and the charge you were trying to prevent can come back on you.
Shopkeeper’s Privilege
Store owners and employees with probable cause to believe someone is shoplifting may detain that person for a reasonable time and in a reasonable manner to investigate.6California Legislative Information. California Penal Code PEN 490.5 This is where most retail-related disputes land. The privilege has real limits. The detention must be brief, the manner reasonable, and deadly force is off the table. Holding a suspected shoplifter in a back room for three hours or assaulting them goes past what the law protects.
Self-Defense and Defense of Others
California law allows proportional force to protect yourself or another person from imminent harm. Restraining someone who was threatening violence to prevent injury can be a complete defense. Proportionality is the key. Confining someone actively swinging at you is defensible. Locking someone in a room because of a verbal argument two hours earlier is not.
Parental Rights
Parents have broad authority to set boundaries for their minor children, including grounding them or restricting where they can go. Sending a teenager to their room is not false imprisonment under ordinary circumstances. The defense fails when the confinement crosses into abuse or uses unreasonable force.
How It Differs From Kidnapping
False imprisonment is a lesser included offense of kidnapping, which means every kidnapping technically includes a false imprisonment but not the other way around.7Justia. CALCRIM No. 1215 Kidnapping The dividing line is movement. Kidnapping under Penal Code 207 requires proof that the defendant moved the victim a substantial distance using force or fear. False imprisonment is about holding someone in place. Blocking someone in a room is false imprisonment. Forcing them into a car and driving across town is kidnapping. In borderline cases where some movement occurred but it was minimal, prosecutors often charge kidnapping and leave false imprisonment as a lesser alternative for the jury.
When It Shows Up in Domestic Violence Cases
False imprisonment charges come up often in domestic situations. Blocking a partner from leaving a room during an argument, taking away their phone and car keys, or threatening harm if they try to walk out the door can all support a charge. When the relationship is domestic — spouses, cohabitants, dating partners, or co-parents — a conviction can trigger consequences beyond the standard penalties: mandatory protective orders, required completion of a batterer’s intervention program, and restrictions on firearm possession under both state and federal law.
Prosecutors in these cases frequently stack false imprisonment with criminal threats or domestic battery. The false imprisonment count sometimes carries the heaviest long-term weight, because a felony conviction follows the defendant long after any sentence ends.
Consequences Beyond the Sentence
A conviction for false imprisonment can also open the door to a civil suit. California defines the civil tort the same way as the crime, and the victim does not need to show physical injury. Recoverable damages include emotional suffering, humiliation, lost time, physical discomfort, business interruption, and harm to reputation. Punitive damages are available in egregious cases.8Justia. CACI No. 1400 False Imprisonment – No Arrest Involved Even an acquittal in the criminal case does not block a civil claim, since the burden of proof is lower on the civil side.
A felony conviction brings additional fallout. Federal law bars anyone convicted of a felony from possessing firearms or ammunition for life unless the conviction is expunged or pardoned, or civil rights are fully restored.9Bureau of Alcohol, Tobacco, Firearms and Explosives. Most Frequently Asked Firearms Questions and Answers The ATF has statutory authority to grant relief from federal firearms disabilities, but Congress has blocked funding for that program every year since 1992, so relief is extremely difficult to obtain in practice.
Professional licensing is another pressure point. Many California boards require disclosure of felony convictions and weigh whether the offense relates to the duties of the profession. A felony involving restraint of another person can be disqualifying in healthcare, education, law enforcement, and social work. Employment prospects narrow for similar reasons once a violent felony shows up on a background check.
For non-citizens, the immigration stakes can be serious. Felony false imprisonment involving violence or threats may be treated as a crime involving moral turpitude or an aggravated felony under federal immigration law, either of which can trigger deportation or inadmissibility. Anyone facing this charge who is not a U.S. citizen should talk to an immigration attorney before considering any plea.
