Missouri recording laws follow a one-party consent rule: you can legally record a phone call or conversation as long as you are a participant, or one participant has given you permission. Recording a conversation you are not part of, without anyone’s consent, is a Class E felony under Missouri Revised Statutes Section 542.402, punishable by up to four years in prison and a $10,000 fine.1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.4022Missouri State Highway Patrol. Senate Bill 491 Summary Civil damages start at $10,000 on top of that.
The One-Party Consent Rule
If you are on the call, you can record it. You do not have to tell the other person. You can also authorize someone else to record a call you are on. What you cannot do is secretly capture a conversation between two other people when none of them agreed.1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.402
The exception has a condition attached. Your recording cannot be made “for the purpose of committing any criminal or tortious act.”1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.402 Recording to blackmail, defraud, or harass someone strips away the protection the statute otherwise gives you. The recording itself then becomes evidence of a separate offense.
Being married to someone does not change any of this. Section 542.400 defines “intercept” to include interception by one spouse of another.3Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.400 A spouse who taps the other spouse’s phone, on a call the tapping spouse is not part of, is intercepting a communication.
What the Statute Actually Covers
The law treats different kinds of recordings differently, and the distinctions matter.
Phone calls and electronic communications. These are “wire communications” under the statute. Both the prohibition and the one-party consent exception clearly apply. Tap someone’s line without consent and you have committed a felony. Record your own call and you are fine.
In-person conversations. Section 542.402 prohibits intercepting oral communications only when the device “transmits communications by radio or interferes with the transmission of such communication.”1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.402 A hidden transmitter or radio bug in someone’s office fits that description. Whether a plain voice recorder on a phone triggers the statute for in-person conversations is less clear from the text. The safe course is to treat the one-party consent rule as applying to any conversation you are part of.
Silent video. Video with no audio is not covered by the wiretapping statute, because nothing is being intercepted. A separate law, Section 565.252, makes it a crime to create images of someone in a state of nudity, without consent, where they have a reasonable expectation of privacy. That offense is a Class A misdemeanor, escalating to a Class E felony if the images are distributed or the offender has a prior conviction.4Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 565.252
Criminal Penalties
Illegally intercepting a wire or oral communication is a Class E felony. So is knowingly disclosing or using the contents of an illegally intercepted communication.1Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 542.402 Class E felonies carry a maximum prison sentence of four years5Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 558.011 and fines up to $10,000.2Missouri State Highway Patrol. Senate Bill 491 Summary
A quick note on older sources. Before January 1, 2017, this offense was a Class D felony under Missouri’s prior classification scheme. Senate Bill 491 restructured the felony classes, converting most former Class D felonies into Class E felonies. If you see wiretapping described as a “Class D felony” in an older article, that reflects the pre-2017 label.
A felony conviction reaches beyond the sentence. Background checks flag it, professional licenses can be revoked or denied, and voting rights may be affected during incarceration.
Civil Damages
The criminal exposure is only half the picture. Section 542.418 lets anyone whose communication was illegally intercepted, disclosed, or used sue the person responsible. The damages available are unusually favorable to victims:
- Actual damages, or liquidated damages of $100 per day of the violation, or $10,000, whichever is greatest.
- Punitive damages when the violation was willful or intentional.
- Reasonable attorney’s fees and litigation costs.6Missouri Revisor of Statutes. Missouri Revised Statutes Section 542.418
The $10,000 floor means a victim does not have to prove specific financial harm to walk away with a meaningful judgment. Fee-shifting means their lawyer gets paid by the defendant if they win. A single illegal recording can turn into a five-figure verdict, and often does.
Recording at Work
Because Missouri uses a one-party consent rule, you can generally record work conversations you participate in: a meeting with your supervisor, a discussion with HR, a call with a coworker. You do not have to announce that you are recording.
The complication is that your employer may have a policy against it. Whether such a policy is enforceable can involve federal labor law. In 2023, the National Labor Relations Board adopted a new standard for evaluating workplace rules that may restrict employees’ rights to engage in protected activity, such as discussing wages or working conditions. A blanket no-recording policy could be found unlawful under that framework if it tends to chill those rights. The NLRB has separately held that employers cannot apply an otherwise lawful no-recording policy to punish activity protected by federal labor law, such as a union representative recording a disciplinary meeting to preserve evidence for a grievance.
The practical point: Missouri’s wiretapping statute lets you record your own workplace conversations, but that is separate from whether your employer can discipline you for it. Those are two different questions with two different answers.
Recording the Police
Most federal appeals courts have recognized a First Amendment right to record officers performing their duties in public. The Eighth Circuit, which covers Missouri, has declined to recognize a clearly established constitutional right to film police in public. That does not make recording police illegal here. It does mean that if an officer interferes with your recording, a civil rights claim is harder to win in Missouri than in circuits where the right is clearly established.
Under the wiretapping statute, recording a police encounter you are personally involved in falls squarely within the one-party consent rule. Recording an encounter between officers and someone else, when you are not part of the conversation, is a different question. Video without audio is not reached by the statute at all. Audio of a conversation you are not part of pulls you back into the analysis of whether the recording device “transmits” or “interferes with” communications.
Interstate Calls and Federal Law
The one-party consent rule governs calls within Missouri. Calls that cross state lines can pull in a stricter rule from the other state. About a dozen states require all parties to consent. If you are in Missouri recording a call with someone in one of those states, courts have not reached a uniform answer on whose law controls. The California Supreme Court, for example, has held that California’s all-party rule applies to conversations between someone in California and someone in a one-party state.
The safe move on an interstate call is to follow the stricter state’s rule, which usually means getting everyone’s consent on the record.
Federal wiretapping law at 18 U.S.C. ยง 2511 mirrors Missouri’s one-party approach. A party to the communication, or someone with a party’s consent, can record under federal law, so long as the recording is not for a criminal or tortious purpose.7Office of the Law Revision Counsel. 18 U.S. Code Section 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited Federal penalties reach up to five years in prison. Federal law is a floor; a state with stricter rules layers additional risk on top.
Using a Recording in Court
A lawfully made recording is not automatically admissible. Missouri law says electronic records cannot be excluded solely because they are electronic,8Missouri Revisor of Statutes. Missouri Revised Statutes Section 432.260 but the recording still has to be authenticated. Someone who was on the call, or witnessed the conversation, usually needs to confirm that the recording accurately captures what was said. Timestamps, caller ID data, and a clean chain of custody help. Edited or spliced recordings run into obvious problems.
Legality is the biggest threshold issue. Section 542.418 restricts the use of illegally intercepted communications in civil proceedings.6Missouri Revisor of Statutes. Missouri Revised Statutes Section 542.418 Getting the consent question right before you press record is not just about criminal exposure. It determines whether the recording is useful at all in a lawsuit.
How Long You Have to Act
Missouri’s general felony statute of limitations is three years, so criminal prosecution for illegal recording has to be brought within that window. On the civil side, Section 516.120 gives a five-year period for injuries to a person’s rights that are not based on contract, and a claim under Section 542.418 fits within that catch-all.9Missouri Revisor of Statutes. Missouri Revised Statutes RSMo Section 516.120
The clocks usually start when the illegal recording or disclosure happens, or when the victim discovers it or should have discovered it. If you think your communications were illegally intercepted, moving early preserves both your ability to file a criminal complaint and your civil recovery.
