Is It Legal to Record a Phone Call in Wisconsin? (2026)

The short answer: Wisconsin is a one-party consent state

If you are a Wisconsin parent asking whether you can record a call with your co-parent, the answer is yes. Wisconsin only requires the consent of one party to a wire, electronic or oral communication, and your own participation in the call is enough to satisfy that requirement. You are not required to tell the other parent before you start recording.

What the statute actually says

The rule is codified at Wis. Stat. § 968.31, Wisconsin’s interception statute. It provides an exception allowing a person to record a wire, electronic or oral communication where “the person is a party to the communication or one of the parties to the communication has given prior consent to the interception.” Because you are on the call, your own consent is enough on its own; you do not need the other parent’s agreement or even their awareness.

This mirrors the federal wiretap act. Under 18 U.S.C. § 2511(2)(d), a party to a communication may lawfully intercept it, provided the purpose is not criminal or tortious. Wisconsin and federal law both set one-party consent as the standard, so a parent recording their own co-parenting call is protected under both at once.

The penalty for getting it wrong

Recording, attempting to record, or knowingly disclosing an illegally intercepted wire, electronic or oral communication without any party’s consent is a Class H felony in Wisconsin. On top of the criminal exposure, § 968.31 gives the person whose communication was illegally intercepted a civil cause of action: they can recover actual damages, or liquidated damages of $100 per day of violation (with a $1,000 floor), whichever is higher, plus punitive damages and attorney’s fees. That dual criminal-and-civil exposure is a serious deterrent against recording a conversation you are not part of.

Notable exceptions and limits

The one-party exception in § 968.31 only protects a recording made by, or with the consent of, an actual party to the communication. It does not extend to bugging a room after you have left, or intercepting a call between your co-parent and a third person that you are not on. Wisconsin also recognizes a First Amendment right to record government officials, including law enforcement, performing their public duties in public — a separate line of protection from the consent statute, but a useful one to know if a custody dispute ever intersects with a public interaction (a school pickup dispute involving a police officer, for example).

Using a recording in a Wisconsin custody case

A recording you took part in is generally admissible in a Wisconsin custody or divorce matter, subject to the ordinary rules on relevance and reliability. As in every state, a complete, unedited, clearly dated recording carries far more weight than a short excerpt with no context, and an edited recording invites a credibility challenge that can undercut the rest of your case. Keep the original audio, log the date and who was on the line, and let your attorney decide how and when to present it.

Recording across state lines: the strictest-rule caveat

Wisconsin’s one-party rule applies to calls under Wisconsin law, but if your co-parent is physically located in an all-party state such as Illinois, Michigan or Pennsylvania during the call, that state’s stricter rule may govern their side of the conversation. When a call could cross state lines, the safer habit is to assume the strictest rule that could apply governs, and announce the recording rather than relying on Wisconsin’s one-party standard alone. Check call-recording laws in all 50 states for the rule wherever your co-parent is located.

How to document it so it holds up

A Wisconsin recording is most persuasive as part of a consistent habit, not a one-off. Preserve full text threads instead of cropped screenshots, keep the original audio file rather than a re-recorded copy, and log the date, time and participants for every recording you keep. Store copies somewhere you control, separate from the phone itself, so a lost or replaced device never costs you the record. A continuous, unedited history is far harder for opposing counsel to attack than an isolated, dramatic clip pulled out of context.

Frequently asked questions

Can I record a phone call with my co-parent in Wisconsin without telling them?
Yes. As a party to the call, your own consent under § 968.31 is enough, with no obligation to announce it.

What happens if I record a conversation I am not part of?
That can be a Class H felony, and the person recorded can also sue you civilly for damages, statutory penalties, and attorney’s fees under § 968.31.

Can I record a police officer or public official in Wisconsin?
Generally yes, when they are performing public duties in public, under First Amendment protections recognized in this circuit — separate from the consent rules that apply to private conversations.

Will a Wisconsin judge automatically admit my recording as evidence?
No. Lawful under § 968.31 is not the same as automatically admissible; the judge still weighs relevance, completeness and how it was obtained.

Can my co-parent also record our calls without telling me?
Yes. Wisconsin’s one-party rule applies to both of you equally: whichever parent is a participant on the call can lawfully record it.

Should I mention the civil damages provision if I take my co-parent to court over a recording?
That is a strategic question for your attorney, not a documentation question. What matters for your own custody case is that your own recordings stay lawful, complete and unedited.

What if my co-parent is calling from a state with a stricter, all-party rule?
Wisconsin’s one-party rule only guarantees your own side of the call is lawful under Wisconsin law. Check the rule for wherever your co-parent is physically located before treating the whole call as covered by Wisconsin’s standard alone.

Does it matter whether the recording app also stores a written transcript?
No, an automatically generated transcript does not change the underlying consent analysis under § 968.31 — it is simply a convenient copy of the same lawfully recorded conversation, and you should still keep the original audio file alongside it.

Can I record a mediation session or a court-ordered custody evaluation call?
Treat any recording tied to a court process as a special case: mediation confidentiality rules and court orders can restrict recording even where § 968.31’s ordinary one-party rule would otherwise allow it, so confirm with your attorney before recording anything tied to a formal proceeding.

Bottom line

In Wisconsin, you may record your own calls and conversations with a co-parent, and a complete, unedited recording can support your custody case. Keep it dated and untouched, mind the interstate caveat, and read how to document a co-parenting conflict for court for how to build a full, court-ready evidence archive that goes well beyond a single phone call.
