Recording Law for Streamers & Creators in Missouri

Missouri allows private citizens to record wire communications—such as phone calls and online chats—if they are a party to the conversation or have one party’s consent. The governing statute, Mo. Rev. Stat. § 542.402, makes it a class E felony to intercept a wire communication under § 542.402.1(1). The law is strictest for wire communications: § 542.402.1(1) criminalizes intercepting any wire communication as a class E felony, while § 542.402.2(3) provides a one-party-consent exception for private citizens who are parties to the communication or have prior consent from one party and who are not acting under law. Missouri’s wiretap statute is expressly tied to audio interception; it does not criminalize video-only recording, which falls outside the statute entirely. For in-person conversations, the statute treats oral communications differently: § 542.402.1(2) criminalizes using a device to intercept an oral communication only when the device transmits communications by radio or interferes with the transmission of the communication—meaning ordinary local-storage recorders are not covered by this prohibition. The one-party-consent exception for private citizens does not extend to oral communications; only law-enforcement officers acting under color of law may rely on the consent provision in § 542.402.2(2), which is expressly limited to 'a person acting under law.'

Missouri’s wiretap statute, Mo. Rev. Stat. §§ 542.400–542.422, defines "intercept" as "the aural acquisition of the contents of any wire communication through the use of any electronic or mechanical device." Because interception under the statute is expressly tied to audio acquisition, a silent video-only recording with no audio component does not constitute an "interception" of a "wire" or "oral" communication and falls outside § 542.402 entirely. Separately, Missouri’s invasion-of-privacy statute, § 565.252, criminalizes photographing or filming another person’s nudity or under clothing without consent in a place where there is a reasonable expectation of privacy. This voyeurism statute is narrow in scope and would not apply to filming a public dispute, interpersonal confrontation, or a police interaction where no nudity is involved. Therefore, under Missouri law, video-only recording is unrestricted by the wiretap statute and is not independently criminalized by the voyeurism statute in most common filming situations.

Missouri’s wiretap statute defines an "oral communication" as "any communication uttered by a person exhibiting an expectation that such communication is not subject to interception under circumstances justifying such expectation." This is a two-part test combining a speaker’s subjective expectation of privacy with an objective assessment of whether that expectation is reasonable under the circumstances. The statute’s privacy gate applies only to oral communications; wire communications are defined purely by mode of transmission and carry no privacy-expectation qualifier. For oral communications, § 542.402.1(2) further narrows the criminal offense to devices that transmit communications by radio or interfere with transmission, so even an oral communication that clears the privacy gate falls outside the criminal ban unless captured by a radio-transmitting or bugging device. The case cited in support of extending the public-place reasoning to street-level disputes—Angel v. Williams, 12 F.3d 786 (8th Cir. 1993)—could not be independently verified across multiple legal databases and search engines, so this extension should be treated as an untested, lower-confidence inference from the statutory text alone rather than settled precedent. In practical terms, conversations occurring in public places where there is no reasonable expectation of privacy likely fall outside the statute’s protection entirely, meaning recording them (audio or video) is not restricted by §§ 542.400–.422 regardless of consent. However, because the public-place extension rests on an unverified citation, the safest approach is to avoid recording one-on-one disputes in public unless the exchange is loud enough to be heard by bystanders and no speaker exhibits privacy-seeking conduct.

Missouri is within the Eighth Circuit, which is a national outlier on the First Amendment right to record police. In Chestnut v. Wallace, 947 F.3d 1085 (8th Cir. 2020), the court held that a person has a clearly established right to passively observe police-citizen interactions from a distance without interfering, denying qualified immunity to an officer who detained a bystander merely watching a traffic stop. However, in Molina v. City of St. Louis (Molina v. Book), 59 F.4th 334 (8th Cir. 2023), cert. denied 2024, a panel held that even assuming the First Amendment protects observing AND recording police conduct, that right was not "clearly established" in the Eighth Circuit as of 2015, so officers who tear-gassed legal observers filming a protest response retained qualified immunity. The net effect is that, unlike most other federal circuits, there is currently no clearly established Eighth Circuit precedent guaranteeing a right to actively film police in Missouri for qualified-immunity purposes, which matters for civil-rights liability even though the underlying constitutional question remains technically open. On the statutory side, Missouri’s wiretap statute does not independently criminalize recording police in public; the general framework and the public-place reasonable-expectation gate apply the same way to police encounters as to any other public interaction. Recording an on-duty officer in a public place is not criminalized by §§ 542.400–.422, but the confrontation context could still expose a recorder to unrelated charges (e.g., interference or obstruction statutes) outside the scope of this wiretap analysis. If you are streaming police activity, keep your recording incidental—do not single out officers or follow them to maintain sustained close-range capture. If an officer directs you to stop recording, compliance is the safer course to avoid escalation, even if you believe you have the right to continue.

Missouri’s wiretap statute applies the same rules everywhere, including inside the home. The statute’s definition of "intercept" expressly includes "interception by one spouse of another spouse," confirming that Missouri (unlike some states) applies its wiretap consent rules fully within the home and between spouses, with no lesser protection there. There is no statutory carve-out making home recording either more permissive or stricter than recording elsewhere. For wire communications at home—such as phone calls between spouses—the one-party-consent exception in § 542.402.2(3) applies to private citizens, making such recordings lawful if one party consents. For in-person conversations at home, the statutory privacy gate in § 542.400(8) applies: a conversation qualifies as an "oral communication" only if the speaker exhibits an expectation that it is not subject to interception under circumstances justifying that expectation. The device limitation in § 542.402.1(2) also applies at home: ordinary local-storage recorders are not covered by the criminal ban unless they transmit by radio or interfere with transmission. In short, while the wiretap statute does not create a special home exemption, the combination of the privacy gate and device limitation means that recording at home is not clearly criminalized by the statute in most ordinary situations.

Missouri does not currently have a biometric privacy law that applies to private companies. The state has one narrow, government-only biometric statute, Mo. Rev. Stat. § 302.170, which restricts the Department of Revenue’s use of biometric data—including voice data—solely in the context of driver’s-license production and does not reach private businesses. Separately, a BIPA-style "Biometric Information Privacy Act" (with a voiceprint-inclusive definition and a private right of action) has been introduced in three consecutive legislative efforts and has died each time: SB554 (2025), HB500 (2025), and HB1970 (2026). Absent such a statute, a private company’s voice-enrollment feature is not currently subject to a Missouri-specific written-consent, notice, or retention/destruction-policy mandate. However, identical BIPA-style bills that would impose exactly such a written-notice-plus-written-release regime (with "voiceprint" expressly named in the biometric-identifier definition) have been introduced and died in three consecutive sessions, meaning Missouri lawmakers have repeatedly attempted—and could plausibly pass in a future session—a law that would directly regulate voice-enrollment features and attach a private right of action to violations. Until such a law is enacted, there are no specific rules about collecting or using voiceprints in Missouri beyond the narrow § 302.170 restriction on state actors.

Missouri’s Supreme Court Advisory Committee (Office of Legal Ethics Counsel) issued Formal Opinion 123 on March 8, 2006, addressing Rules 4-1.4 and 4-8.4(c) of the Missouri Rules of Professional Conduct. The opinion squarely addresses whether an attorney may secretly record a conversation with a nonclient and expressly adopts the ABA’s permissive approach, stating: "The Advisory Committee agrees with the reasoning of ABA Formal Opinion 01–422." The operative holding is: "An attorney may record a conversation, to which the attorney is a party, without notifying the other parties to the conversation, unless other factors are present." This permission is conditioned on three requirements, each independently confirmed from the primary source: (1) Legality—"An attorney may not record a conversation, secretly or otherwise, if the act of recording would be illegal," making the ethical permission contingent on compliance with Missouri’s one-party-consent wiretap statute; (2) No independent deceit—"An attorney may not engage in dishonesty, deception, misleading statements, or misrepresentation about whether the attorney is recording the conversation," so affirmatively lying when directly asked would still violate Rule 4-8.4(c); and (3) Current-client carve-out—"If the recording is of a conversation with a current client, the attorney must give some notice to the client that the attorney is, or may be, recording the conversation," a duty tied to Rule 4-1.4’s client-communication requirement and not extended to nonclients. In short, undisclosed recording of a nonclient conversation is not itself unethical in Missouri, provided it is legal under state law and not accompanied by an independent lie about the fact of recording, but a Missouri lawyer must give some notice to their own current client that recording is happening or may happen.

Imagine you are livestreaming a protest in downtown St. Louis. You are holding your phone, capturing video and audio of the crowd and police officers managing the event. You are not singling out any officer, and the audio is loud enough that bystanders can hear the chants. Under Missouri’s wiretap statute, this recording is not criminalized because the wiretap law is tied to audio interception and does not restrict video-only recording, and because the exchange occurs in a public place where there is no reasonable expectation of privacy. However, the public-place extension rests on an unverified citation, so treat this as a reasoned outcome rather than settled law. If an officer approaches you and says, "Stop recording me," you are in a qualified-immunity gray area: the Eighth Circuit has not clearly established a First Amendment right to actively record on-duty police, so an officer could still detain you or order you to stop under the doctrine of Molina v. Book. In this scenario, the safer move is to lower your phone or stop recording the officer directly, even if you believe you have the right to continue, to avoid escalation and potential unrelated charges outside the wiretap statute.
