Michigan is technically a two-party consent state on the face of its eavesdropping statute, but Michigan courts have consistently held that a person who takes part in a conversation is not “eavesdropping” when they record it. The practical result is that you can record a conversation you are part of without telling anyone else, and Michigan functions as a one-party consent state even though the statute reads otherwise. Getting the distinction wrong is costly: illegal eavesdropping in Michigan is a felony, not a misdemeanor.
What the Statute Says
The core provision is MCL 750.539c, which makes it a felony to use any device to eavesdrop on a private conversation without the consent of all parties.1Michigan Legislature. MCL – Section 750.539c Read alone, that sounds like every voice on the line has to agree before anyone hits record.
The definitions section is where the meaning shifts. MCL 750.539a defines “eavesdrop” as overhearing, recording, amplifying, or transmitting “the private discourse of others.”2Michigan Legislature. Michigan Penal Code Chapter LXXXII – Section 750.539a Those last two words do the work. If you are one of the people talking, the conversation is not purely the discourse “of others” from where you stand.
Why Participant Recording Is Legal
The Michigan Court of Appeals resolved this in Sullivan v. Gray in 1982. The court held that the statutory language “unambiguously excludes participant recording from the definition of eavesdropping by limiting the subject conversation to ‘the private discourse of others.'”3Justia Law. Sullivan v Gray – 1982 – Michigan Court of Appeals The eavesdropping law targets third parties who secretly listen in. A participant who records the call is just making “a more accurate record of what was said.”
The court also addressed the statute’s reference to “any person who is present or who is not present.” That phrase acknowledges that third-party spying can happen from across the room or through a remote device. It does not sweep participants into the prohibition.3Justia Law. Sullivan v Gray – 1982 – Michigan Court of Appeals Federal courts sitting in Michigan have followed the same reading. In AFT Michigan v. Project Veritas (E.D. Mich. 2021), the court confirmed that “the statute is not violated when a conversation is recorded by one of its participants.”
The practical rule: if you are part of the conversation, whether in person, over the phone, or on video, Michigan law lets you record it without notifying anyone. If you are not part of the conversation, you need every participant’s consent, or you have committed a felony.
What Counts as a Private Conversation
The eavesdropping statute only reaches private conversations. A “private place” under the statute is somewhere a person can reasonably expect to be free from uninvited surveillance, and it does not include places open to the public or to a large group.2Michigan Legislature. Michigan Penal Code Chapter LXXXII – Section 750.539a Michigan courts test privacy expectations using the framework from Katz v. United States: the person must actually believe the conversation is private, and society must recognize that belief as reasonable.4LII / Legal Information Institute. Katz and the Adoption of the Reasonable Expectation of Privacy Test
A conversation in your living room or a closed office is clearly private. A conversation in a crowded bar, a public park, or on a busy sidewalk usually is not. The less control you have over who can overhear, the weaker the privacy claim. Recording in a public setting rarely triggers the eavesdropping statute at all.
Hidden Devices Are a Separate Offense
Michigan draws a hard line between recording a conversation you are part of and planting equipment to capture conversations you are not. MCL 750.539d makes it a felony to install any device in a private place to observe, record, or eavesdrop without the consent of the person entitled to privacy there.5Michigan Legislature. MCL – Section 750.539d Hidden cameras, audio recorders, and other monitoring gear all fall under this provision.
There is a narrow carve-out for residential security monitoring conducted by or at the direction of the owner or primary occupant, provided it is not done for a voyeuristic purpose.5Michigan Legislature. MCL – Section 750.539d A nanny cam in the living room is fine. One in a bathroom or guest bedroom is not. And if a home security camera picks up private conversations between third parties, the eavesdropping statute can still apply to whatever audio was captured of discussions you were not part of.
Criminal Penalties
Michigan treats illegal eavesdropping as a felony across the board. Eavesdropping on a private conversation without the consent of all parties carries up to two years in state prison, a fine of up to $2,000, or both.1Michigan Legislature. MCL – Section 750.539c Older guides sometimes call this a misdemeanor. It is not.
Related conduct carries its own felony exposure:
- Installing a surveillance device in a private place without consent: up to two years and $2,000 for a first offense, and up to five years and $5,000 for a second.5Michigan Legislature. MCL – Section 750.539d
- Distributing a recording, photo, or video you know was captured in violation of the surveillance statute: up to five years and $5,000.5Michigan Legislature. MCL – Section 750.539d
- Knowingly using or divulging information from an illegal recording, even if someone else made it: up to two years and $2,000.6Michigan Legislature. Michigan Penal Code Chapter LXXXII – Section 750.539e
Each stage carries its own criminal weight, from the original recording through sharing what it captured.
Civil Exposure
Anyone whose conversation was illegally recorded can also sue. MCL 750.539h authorizes three remedies: an injunction against further eavesdropping, actual damages, and punitive damages as set by the court or jury.7Michigan Legislature. Michigan Penal Code Chapter LXXXII – Section 750.539h The punitive damages piece has no statutory cap.
Federal law adds another layer. Under 18 U.S.C. § 2520, a person whose communications were illegally intercepted can recover the greater of actual damages plus the violator’s profits, or statutory damages of $100 per day of violation or $10,000, whichever of those two is higher.8Office of the Law Revision Counsel. 18 U.S. Code 2520 – Recovery of Civil Damages Authorized Attorney’s fees are recoverable under the federal statute, and the federal claim can be brought alongside the state one. A single illegal recording can therefore expose the person who made it to at least $10,000 in federal statutory damages on top of whatever a Michigan court awards.
Cross-State Calls Change the Analysis
The participant-recording rule works cleanly when everyone on the call is in Michigan. It gets complicated the moment the other person is somewhere with an all-party consent statute. California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania, and Washington are among the states that require every participant to agree. You can comply with Michigan law and violate theirs on the same call.
The federal Wiretap Act sets a floor, not a ceiling. It permits recording when one party consents, but it does not preempt stricter state laws.9Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited A stricter state can enforce its statute against a person who recorded from a one-party jurisdiction.
The California Supreme Court took this position squarely in Kearney v. Salomon Smith Barney, Inc. (2006). A Georgia firm routinely recorded calls with California clients. Georgia is a one-party consent state; California is not. The court held that California’s all-party consent law applied because failing to enforce it would significantly undermine California’s interest in protecting its residents’ privacy.10FindLaw. Kearney v Salomon Smith Barney Inc – 2006 The court declined to impose monetary damages for past conduct given the reasonable reliance on Georgia law, but it allowed the case to proceed for injunctive relief.
Courts resolving these conflicts typically apply a “most significant relationship” analysis, weighing which state has the strongest connection to the dispute. There is no universal answer. If you are recording a call and the other person is out of state, getting explicit consent removes the conflict.
Workplace Recording
Participant recording works the same at work as anywhere else. If you are in a meeting or on a call with a coworker, supervisor, or client, Michigan law lets you record it without saying so. Employees frequently use this rule to preserve evidence of discrimination, harassment, or retaliation.
Employers have their own footing under federal law. The federal Wiretap Act permits interception by a party to the communication or with one party’s consent, and it recognizes a “business extension” exception for monitoring calls on employer-owned equipment when there is a legitimate business justification.9Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited An employer who records private conversations between employees without any participant’s consent has the same felony exposure as anyone else under Michigan’s statute.
Company policy is a separate matter. Many employers prohibit workplace recording in their handbooks. Breaking that rule is not a crime, but it can cost you your job. If recording at work is something you are considering for legal purposes, talking to an attorney first is worth the time.
How Federal Law Lines Up
Federal law under 18 U.S.C. § 2511 prohibits intercepting wire, oral, or electronic communications, but it carves out recording done by a party to the communication or with one party’s prior consent, so long as the recording is not made to further a crime or tort.9Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited A violation of the federal statute carries up to five years in prison.
Federal one-party consent lines up with how Michigan courts read the state eavesdropping law, so a Michigan resident recording their own conversation inside Michigan is unlikely to run into a conflict between the two. Federal law does most of its work in cross-state situations and provides the civil damages remedy discussed above.
