Wisconsin Recording Laws (2026): One-Party Consent Rules

Wisconsin is a one-party consent state under Wis. Stat. § 968.31(2)(c). Any participant in a wire, electronic, or oral communication may record without notifying the other parties, unless the recording serves a criminal, tortious, or otherwise injurious purpose. Recording without any party's consent is a Class H felony, and victims can sue for civil damages.

Recording in-person conversations in Wisconsin

Wisconsin is a one-party consent state. Under Wis. Stat. § 968.31(2)(c), a private actor who is a party to the conversation may record without telling anyone else, as long as the recording is not made for a criminal, tortious, or otherwise injurious purpose. The criminal offense at § 968.31(1) is a Class H felony that reaches only recordings where no party consents.

Wisconsin's Electronic Surveillance Control Law (WESCL), codified at Wis. Stat. §§ 968.27 to 968.37, covers in-person "oral communication" when uttered with a reasonable expectation of privacy under Wis. Stat. § 968.27. This is an important scope point: a private conversation in a closed office or home falls within the statute; a chat in a crowded public lobby probably does not, because there is no justified privacy expectation. Wisconsin thus covers face-to-face recording that some neighboring states (like Indiana) exclude from their wiretap chapters.

Wisconsin's defining quirk is the injurious-purpose clause. The participant exception disappears when recording is made "for the purpose of committing any criminal or tortious act... or for the purpose of committing any other injurious act." The phrase "any other injurious act" is broader than the federal ECPA equivalent at 18 U.S.C. § 2511(2)(d), which stops at "criminal or tortious." Recording to extort, harass, stalk, defame, or accomplish another wrong against the speaker forfeits the exception even if you are a party to the call.

The Wisconsin Supreme Court applied this framework in State v. Duchow, 2008 WI 57: parents consented on behalf of their minor child to a school-bus recording, and the Court held that vicarious parental consent is valid under § 968.31(2)(c) where the parent has an objectively reasonable basis for concern about the child's safety. State v. House, 2007 WI 79 set the totality-of-the-circumstances test for consent voluntariness in the color-of-law context.

Practical advice: confirm you are a participant, not merely someone who placed a device and left the room (the exception requires you to be a party). For sensitive recordings, note the location and participants. Do not edit originals, because authentication challenges are easy to mount against spliced clips.

Recording phone calls in Wisconsin

Phone calls, video calls, and other transmitted communications fall within the WESCL "wire communication" and "electronic communication" categories under § 968.27. Wisconsin's one-party rule applies equally: if you are a party to the call, you may record. The same injurious-purpose limit applies.

The definition of "electronic communication" is technology-neutral and reaches VoIP calls, video conferencing (Zoom, Teams, Google Meet), and voice-message apps (WhatsApp, Signal voice notes). Platforms that postdate the statute still fall within the category.

Multistate calls. When a party is in an all-party consent state (California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania, Washington, or another strict-state jurisdiction), that state's law typically governs if it is stricter. A Wisconsin caller dialing an Illinois number assumes Illinois Eavesdropping Act exposure. Conservative practice: announce the recording at the start, or get express consent.

Business call recording. A Wisconsin business is a participant in its own customer-service and sales calls and may record under § 968.31(2)(c). Multistate operators should provide a recorded-notice announcement at the start of every call to address the strictest applicable state. The old FCC beep-tone rule (47 C.F.R. § 64.501) was removed effective November 20, 2017 and is not live law.

Hidden cameras, doorbells, and nanny cams

Wisconsin's privacy-of-image statutes sit alongside, not inside, the WESCL audio chapter. A single surreptitious recording device can violate both § 968.31 (audio of a private oral communication) and § 942.08 (video surveillance device in a private place).

Wis. Stat. § 942.08 (voyeurism). Subsection (2) is a Class A misdemeanor (up to 9 months' jail, $10,000 fine) for knowingly installing or using a surveillance device in a private place to observe a nude or partially nude person without consent, peeping into a public-accommodation changing room or toilet for sexual gratification, or entering another's property without consent to view a residence from a non-public vantage point. Subsection (3) escalates to a Class I felony (up to 3 years 6 months, $10,000 fine) for knowingly viewing, broadcasting, or recording under the outer clothing of an individual their genitals, pubic area, breasts, or buttocks without consent (no sexual gratification element is required). Subsection (4) enhances any subsection (2) violation to a Class I felony when the victim is under 18.

Wis. Stat. § 942.09 (representations depicting nudity). The base offense under subsection (2)(am)1 is a Class I felony for capturing an intimate representation without the depicted person's knowledge and consent when they have a reasonable expectation of privacy. Posting a private representation of an adult without consent under subsection (3m)(a)1 is a Class A misdemeanor (enhanced to Class H felony when the victim is under 18). The 2025 Wisconsin Act 34 additions (synthetic intimate representation) are addressed in the Special Topics section below.

Audio caveat for home cameras. A Ring doorbell or nanny cam recording conversations inside a Wisconsin home where no participant has consented may trigger WESCL exposure under § 968.31 in addition to the § 942.08 video analysis. Configure audio-capable devices so that at least one household participant is a party to any recorded conversation, or disable audio if the purpose is purely video security.

Wis. Stat. § 942.10 (drone surveillance). Using a drone with intent to photograph, record, or observe a person in a place with a reasonable expectation of privacy is a Class A misdemeanor. Law enforcement operating under § 175.55(2) authorization is exempt.

Penalties for illegal recording in Wisconsin

Criminal penalties under the WESCL and the privacy-of-image statutes:

Civil remedy under § 968.31(2m): the greater of actual damages, $100 per day of violation, or $1,000 minimum (liquidated, so no separate proof of economic harm is required), plus punitive damages for willful violations, plus reasonable attorney fees and litigation costs. The Wisconsin civil floor ($1,000) is lower than the federal ECPA floor at 18 U.S.C. § 2520 ($10,000); federal claims are available when the conduct also violates ECPA.

A felony conviction under § 968.31(1) carries the collateral consequences that attach to any Wisconsin felony: a permanent record, potential loss of federal firearm rights under 18 U.S.C. § 922(g), and restrictions on professional licensing and housing. Wisconsin does not provide for general expungement of adult felony convictions; restoration typically requires an executive pardon.

Recording the police in Wisconsin

Wisconsin sits in the Seventh Circuit. The controlling First Amendment authority is ACLU of Illinois v. Alvarez, 679 F.3d 583 (7th Cir. 2012): the court held that audio-recording on-duty police officers performing public duties is protected by the First Amendment and that criminalizing all nonconsensual audio recording is not narrowly tailored to the state's privacy interest. The decision binds Wisconsin federal courts.

Wisconsin has no separate state right-to-record statute. Combined with the participant-consent rule at § 968.31(2)(c), a citizen openly recording police in public is protected on two independent grounds: the First Amendment (Alvarez) and the participant-consent exception (the citizen is a party to their own observation).

You may film traffic stops, record public arrests, document use of force, and livestream encounters from public property. You may not interfere with police operations, obstruct an officer, or trespass onto private property to record. Comply with lawful time, place, and manner instructions on the spot; challenge a pretextual order through proper legal channels afterward.

Special topics in Wisconsin

Deepfakes and synthetic intimate imagery (2025 Wisconsin Act 34)

2025 Wisconsin Act 34 (originating as 2025 Senate Bill 33, signed October 2, 2025) amended Wis. Stat. § 942.09 in three places. Section 942.09(1)(e) defines "synthetic intimate representation" as a technologically generated representation using an identifiable person's face, likeness, or distinguishing characteristic to depict an intimate representation, so realistic that a reasonable person would believe it depicts actual conduct of that person. Section 942.09(2)(am)4 makes it a Class I felony to post, publish, distribute, or exhibit such a representation with intent to coerce, harass, or intimidate. Section 942.09(3m)(a)3 reaches related posting conduct. Note the placement: synthetic intimate representation is § 942.09, not § 942.08 (the separate voyeurism statute).

Election synthetic-media disclaimer (2023 Wisconsin Act 123)

2023 Wisconsin Act 123 requires AI-disclosure tags on any campaign-finance regulated audio or video communication that contains "synthetic media" generated substantially by generative AI. Audio communications must include "Contains content generated by AI" at both the beginning and end. Forfeiture up to $1,000 per violation; broadcasters and carriers are shielded. This is a separate statute from Act 34: one covers intimate deepfakes (Class I felony), the other covers election-period synthetic media (campaign-finance forfeiture).

Federal TAKE IT DOWN Act overlay

The federal TAKE IT DOWN Act, Pub. L. 119-12 (signed May 19, 2025) criminalizes knowing publication of non-consensual intimate imagery, including AI deepfakes, and requires covered platforms to remove flagged content within 48 hours. Platform compliance under Section 3 was effective May 19, 2026. Wisconsin victims have a stacked remedy: state criminal prosecution under § 942.09 (as expanded by Act 34), state civil remedies, and federal remedies under TAKE IT DOWN.

Workplace recording and NLRB Section 7

Wisconsin's one-party rule governs the criminal analysis: as a participant in a workplace conversation you may record without telling a coworker, subject to the tortious-purpose limit. Criminal-law permission is not employment-law immunity: Wisconsin is an at-will employment state, and employers can discipline employees for violating a valid no-recording policy. Under NLRB Stericycle, Inc., 372 NLRB No. 113 (Aug. 2, 2023), a blanket no-recording rule is presumptively unlawful under Section 7 unless it advances a legitimate business interest that cannot be served by a narrower rule. NLRB GC 25-05 (Feb. 14, 2025) reinstated Boeing-era enforcement discretion but did not overrule Stericycle. NLRB GC 25-07 (June 25, 2025) addresses surreptitious recording of NLRA collective-bargaining sessions specifically: covert recording of a bargaining session is per se bad-faith bargaining under Section 8(a)(5) or 8(b)(3). For detailed coverage, see the Wisconsin Workplace Recording Laws spoke.

Lawyer ethics: State Bar EF-24-01

Wisconsin State Bar Formal Ethics Opinion EF-24-01 (Feb. 6, 2024) is the controlling Wisconsin attorney-ethics authority on surreptitious recording. Recording a client without disclosure violates SCR 20:1.4(b) and SCR 20:8.4(c). Recording a judge or court staff is prohibited. Lying about whether a recording is occurring violates SCR 20:4.1(a). The opinion does not change the underlying criminal-law one-party rule; the consequence for a noncompliant lawyer is professional discipline, not a felony.

Body-worn cameras (Wis. Stat. § 165.87)

Wis. Stat. § 165.87 (last substantively amended by 2021 Wisconsin Act 240) requires agencies to maintain written policies on use, storage, and training, and sets a 120-day minimum retention floor. Recordings depicting death, injury, custodial arrest, authorized search, or use of force must be retained until final disposition of any related investigation, case, or complaint. Body-camera footage is subject to Wisconsin's Public Records Law at § 19.35: to obtain a recording, file a public-records request with the agency identifying the date, time, location, and officer; a complete denial must cite a specific statutory exception.

Admissibility of recordings in Wisconsin courts (§ 885.365)

A recording made lawfully under § 968.31(2)(c) is generally admissible in civil proceedings when the proper foundation is laid under Wis. Stat. § 885.365: authentication (voice identification, distinctive characteristics, or recorder testimony), relevance, and chain of custody. Section 968.31(3) expressly excludes unlawfully obtained recordings from any proceeding except one to prove a § 968.31 violation. Do not edit or splice originals; edited clips draw authentication challenges under the Wisconsin Best Evidence Rule at § 910.02.
