Wisconsin: Call and Conversation Recording Consent Requirements
The short answer
Wisconsin generally permits a private person to record a wire, electronic, or protected oral communication when the recorder is a party or one party gave prior consent, unless the purpose is criminal, tortious, or otherwise injurious. A violation is a Class H felony. Lawful recording does not ensure courtroom use: Wisconsin separately restricts recorded telephone evidence in civil actions, and official annotations say ordinary one-party recordings generally cannot be used as evidence-in-chief unless a statutory authorization or narrow exception applies.

| Governing law and covered recording | Wis. Stat. §§ 968.27 and 968.31 govern intentional device-based acquisition of wire, electronic, and protected oral communications and knowing disclosure or use of unlawfully intercepted contents; § 885.365 separately controls recorded telephone evidence in civil actions |
|---|---|
| Whose consent a participant needs | One-party rule. A private person may intercept when the recorder is a party or one party gave prior consent, unless the purpose is criminal, tortious, or otherwise injurious (§ 968.31(2)(c)) |
| Privacy, confidentiality, or secrecy trigger | An in-person oral communication is protected only when the speaker exhibits an expectation against interception under circumstances justifying it (§ 968.27(12)); the statutory wire and electronic definitions do not contain that expectation element |
| Telephone, in-person, and electronic coverage | Wire communications include aural transfers carried partly through wire/cable facilities and their electronic storage; electronic communications broadly include transmitted sounds and data. The handset-to-base radio portion of a cordless call is excluded from the electronic-communication definition (§ 968.27(4), (17)) |
| How consent or notice is given | Being a party is independently sufficient for legality; otherwise one party must give prior consent. Section 968.31(2)(c) prescribes no writing, script, or tone. Separately, a § 885.365(2)(a) civil-evidence exception requires contemporaneous notice that the call is recorded and may be used in court, or a qualifying connector producing a tone about every 15 seconds |
| Major participant-facing exceptions | The private one-party exception fails when the recording's purpose is criminal, tortious, or otherwise injurious. Other express exceptions cover provider operations, public-access electronic or radio communications, and interference tracing (§ 968.31(2)(a), (d), (e), (g)) |
| Criminal classification and penalty | Intentional unlawful interception, knowing disclosure or use, and intentional alteration under § 968.31(1) are Class H felonies: up to 6 years' imprisonment, a fine up to $10,000, or both (§ 939.50(3)(h)) |
| Civil remedy and evidence effect | Section 968.31(2m) provides actual damages with a floor of $100 per day or $1,000, whichever is higher, plus reasonable attorney fees and costs. Section 885.365 restricts recorded telephone evidence in civil actions; official § 968.29 annotations also say lawful one-party recordings generally are not admissible as evidence-in-chief without statutory authorization, subject to narrow exceptions |
| Interstate and federal boundary | Federal law permits a participant or one-party-consented recording unless its purpose is criminal or tortious (18 U.S.C. § 2511(2)(d)); Wisconsin adds an 'other injurious act' purpose limit and distinct evidence rules. Choice of law is fact-specific, so all-party consent is the prudent interstate baseline |

Requirements one by one
Governing law and covered recording
Section 968.31(1) makes it a Class H felony to intentionally intercept a wire, electronic, or oral communication outside an exception. It separately reaches disclosure or use when the person knows or has reason to know the contents came from an interception violating the section. Section 968.27(9) supplies the device element: interception is acquisition of the contents “through the use of any electronic, mechanical or other device.”
Whose consent a participant needs
For a private person, § 968.31(2)(c) permits interception when “the person is a party to the communication or where one of the parties to the communication has given prior consent.” A participant therefore does not need every other participant's consent merely to make the recording. The permission disappears if the recording is made for a criminal, tortious, or “other injurious” purpose.
Privacy, confidentiality, or secrecy trigger
The expectation test belongs to in-person speech. Section 968.27(12) defines an oral communication as one uttered by a person “exhibiting an expectation that the communication is not subject to interception under circumstances justifying the expectation.” The official annotation to § 968.27 describes this as both an actual subjective expectation and one society is willing to recognize as reasonable, assessed from the total circumstances. The wire and electronic definitions do not repeat that test.
Telephone, in-person, and electronic coverage
A telephone voice transfer carried at least partly by wire or cable is a wire communication, and the definition includes electronic storage of that aural transfer (§ 968.27(17)). The electronic-communication definition separately covers transmitted “sounds” and “data,” but expressly excludes the radio portion between a cordless handset and its base (§ 968.27(4)(a)). Face-to-face speech is evaluated under the protected-oral-communication definition.
How consent or notice is given
Section 968.31(2)(c) requires prior consent only when the recorder is not a party and gives no required writing, spoken formula, or warning tone. Court use is different. For the civil-evidence exception in § 885.365(2)(a), the person recorded must be informed at the time both that the conversation is being recorded and that resulting evidence may be used in court; the same paragraph also recognizes a qualifying telephone connector that automatically produces a distinctive tone at roughly 15-second intervals.
Major participant-facing exceptions
Wisconsin does not state a broad private evidence-gathering exception. Instead, the participant permission itself is subject to the criminal, tortious, or other-injurious-purpose limit. Other statutory exceptions are medium or operator based, including provider activity necessary to service or property protection, public-access electronic or radio communications, and interception needed to identify harmful interference (§ 968.31(2)(a), (d), (e), (g)).
Criminal classification and penalty
The prohibited acts listed in § 968.31(1) are Class H felonies. The current general penalty provision sets the maximum at “a fine not to exceed $10,000 or imprisonment not to exceed 6 years, or both” (§ 939.50(3)(h)).
Civil remedy and evidence effect
Wis. Stat. § 968.31(2m) creates a civil action for unlawful interception, disclosure, or use. It awards actual damages, subject to a statutory floor of $100 per violation day or $1,000, whichever is higher, plus reasonable attorney fees and litigation costs. Good-faith reliance on a court order or § 968.30(7) is a complete civil or criminal defense (§ 968.31(3)).
Evidence is a separate question. Wis. Stat. § 885.365(1) says recorded telephone evidence is “totally inadmissible” in Wisconsin civil actions unless a statutory exception applies. The official § 968.29 annotations likewise state that one-party tapes may be lawful yet not authorized for admission as evidence-in-chief. Those annotations identify narrow departures, including when a party opens the door by relying extensively on the transcript and the criminal “plain hearing” situation described in State v. Gil.
Interstate and federal boundary
Federal § 2511(2)(d) permits a private interception when the recorder is a party or one party gave prior consent, unless its purpose is criminal or tortious. Wisconsin's recording permission is similar but adds “any other injurious act” and its own evidence restrictions. Neither rule resolves which state's law governs a multistate call; obtaining every participant's consent is the prudent operational baseline.
What trips people up
Lawful to make does not mean admissible in court. Wisconsin's one-party permission answers interception legality. Sections 885.365 and 968.29 answer different questions about courtroom use and can keep a lawful recording out of evidence-in-chief.
A civil-use warning says two things. The § 885.365(2)(a) exception is not satisfied by announcing only that a call is recorded; its text also requires informing the person that resulting evidence may be used in court.
The purpose limitation is broader than the federal wording. Wisconsin includes a recording made for “any other injurious act,” not only a criminal or tortious purpose. Whether a particular purpose is injurious is fact-specific.
Common questions
May someone who is not on the call record it if one caller agrees? Section 968.31(2)(c) permits a private person to intercept when one party gave prior consent, subject to the prohibited-purpose limit. Separate laws or duties may still apply to the use or disclosure of the result.
May I give a lawful one-party recording to law enforcement? The official § 968.29 annotation for State v. Waste Management says the evidence-in-chief restriction does not itself prohibit giving such a tape to the state. Whether and how it can then be disclosed or admitted is a separate, fact-specific question.
