Recording Law for Recording in Public in Wisconsin

Wisconsin law lets you record any conversation you are part of without telling the other person or people. The rule comes from Wisconsin’s Electronic Surveillance Control Law, specifically Wis. Stat. § 968.31. That statute makes it a crime to intercept a "wire, electronic, or oral communication" unless one party to the communication has given prior consent. Because you are a party to the conversation, your recording is lawful even if others don’t know it’s happening. The law treats in-person chats, phone calls, and electronic messages the same way—one-party consent applies across all types of communication. Wisconsin’s one-party consent provision states that interception is lawful where "one of the parties to the communication has given prior consent to the interception." A separate provision extends the same one-party consent rule to persons not acting under color of law, except where the interception is done "for the purpose of committing any criminal or tortious act."

Recording video without sound in a public place is not restricted by Wisconsin’s wiretap law. Wis. Stat. § 968.31 only prohibits the acquisition of the "contents" of a wire, electronic, or oral communication, and silent video does not acquire those contents. The statute defines "intercept" as "the aural or other acquisition of the contents of any wire, electronic or oral communication through the use of any electronic, mechanical or other device," which requires audio capture. So filming people in parks, sidewalks, or stores without audio is allowed. There is a separate, narrower law, Wis. Stat. § 942.08, that bans using a "surveillance device" in a private place to observe someone who is nude or partially nude, but that does not apply to general public recording. If you’re only capturing video and not audio, you’re not breaking Wisconsin’s wiretap law.

You have the right to record on-duty police officers performing their duties in public. Wisconsin is in the federal Seventh Circuit, and the Seventh Circuit’s decision in ACLU v. Alvarez, 679 F.3d 583 (7th Cir. 2012), held that openly recording police officers while they work in public is protected by the First Amendment. Wisconsin’s one-party consent law also allows you to record conversations you’re part of, which includes interactions with police. Courts use a totality-of-circumstances test from State v. Duchow, 2008 WI 57, 310 Wis. 2d 1, 749 N.W.2d 913, to decide whether a conversation had a reasonable expectation of privacy. Loud, public police interactions usually don’t meet that test, so recording them is clearly protected. The Seventh Circuit’s ruling is binding precedent applicable to Wisconsin, even though no Wisconsin case has directly confirmed it. Just don’t interfere with police operations while recording.

Not every conversation is fair game for recording, even if it happens outside. Wisconsin’s wiretap law protects conversations where the speaker has a reasonable expectation of privacy, regardless of location. The Wisconsin Supreme Court’s decision in State v. Duchow sets out six factors to decide if a conversation was private: the volume of the statements, how close other people were, whether the conversation could easily be overheard or reported, whether the speaker took steps to keep it private, whether technology was needed to hear it, and where it took place. For example, a conversation in a quiet corner of a café where speakers lower their voices and take visible steps to keep the exchange private could still qualify as private, even though it’s technically in public. If the conversation meets the Duchow test, recording it without consent could violate the law.

Recording a conversation in violation of Wisconsin’s wiretap law is a Class H felony. That means you could face up to six years in prison, a fine of up to $10,000, or both. The law also allows the person you recorded to sue you in civil court. The civil cause of action is created by Wis. Stat. § 968.31(2m), and it permits recovery of actual damages of at least $100 per day or $1,000, whichever is greater, plus punitive damages and attorney’s fees. These penalties apply only when you unlawfully intercept a wire, electronic, or oral communication under § 968.31. The civil lawsuit can be filed even if the prosecutor decides not to bring criminal charges. So even if you think your recording is harmless, the person you recorded could take you to court if your recording violated the statute.

Imagine you’re at a park and two people start a loud argument nearby. You pull out your phone and record the exchange without telling them. Because the argument is loud, occurs in an open area with other people around, and neither speaker takes steps to keep the conversation private, it likely doesn’t have a reasonable expectation of privacy under State v. Duchow. Your recording is lawful under Wisconsin’s one-party consent rule since you’re part of the conversation. If you only record video without sound, you’re not covered by the wiretap law at all. But if the two people step into a quiet, secluded area, lower their voices, and take visible steps to keep the exchange private, the Duchow factors might weigh toward privacy, and recording could be illegal. Always pay attention to the setting, volume, and whether speakers take visible steps to keep the conversation private before you record.

Wisconsin’s wiretap statute has no distinct, stricter statutory carve-out specifically for recording inside one’s own home; the same one-party-consent / reasonable-expectation-of-privacy framework under § 968.31 and § 968.27(12) governs everywhere, home or not. If the person recording is a participant in a conversation occurring in their own home, one-party consent applies just as it would elsewhere. Recording someone else’s conversation in a location—including a home—where a nonparticipant has no consent and the parties reasonably expect privacy could still trigger liability under § 968.31. The law looks at the totality of the circumstances, including whether the speaker took steps to keep the conversation private, the volume of the statements, and the location. Separately, Wis. Stat. § 942.08(2)(a) (invasion of privacy) has heightened, location-based force in homes/private places, but again only reaches installing/using a surveillance device to observe nude or partially nude persons without consent—not general dispute/incident recording.

Recording conversations in private spaces—such as homes, private offices, or hotel rooms—is governed by the same one-party consent and reasonable-expectation-of-privacy framework that applies everywhere under § 968.31 and § 968.27(12). If the person recording is a party to the conversation, the recording is lawful even without consent. However, if the recorder is not a party and the speakers take visible steps to keep the conversation private (lowering voices, moving to a secluded area, asking others to step back), the Duchow totality-of-circumstances test may weigh toward a reasonable expectation of privacy, making the recording unlawful. The statute does not create a categorical home-specific exception; location is simply one factor in the analysis. Separately, Wis. Stat. § 942.08(2)(a) restricts the use of a surveillance device in a private place to observe a nude or partially nude person without consent, but it does not broadly prohibit recording disputes or incidents in private spaces.
