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

Is it legal to record a phone call in Kansas?

Yes. Kansas is a one-party consent state. If you are a participant in a phone call or a private in-person conversation, your own consent is enough to record it lawfully — you do not need to tell the other person, and you do not need a court order. For a parent trying to keep an honest, complete record of a difficult exchange with a co-parent, that means every call you are on is yours to record.

The statute and the exact citation

The rule sits in Kan. Stat. Ann. § 21-6101, “Breach of privacy.” Subsection (a)(1) makes it unlawful to intercept, without the consent of the sender or receiver, a message sent by telephone, telegraph, letter, or other means of private communication. Read carefully, that phrasing is what creates Kansas's one-party rule: the statute only bites when neither the sender nor the receiver has consented. Because you are the sender or receiver on your own call, your consent alone takes the recording outside the statute entirely.

Penalties for recording without the exception

Violating § 21-6101(a)(1) through (a)(5) is a class A nonperson misdemeanor in Kansas, punishable by up to one year in jail and a fine of up to $2,500. That penalty is aimed at someone who intercepts a private communication with no participant's consent at all — not at a parent who is a party to their own call. Kansas's breach-of-privacy statute also reaches further than phone calls: separate provisions in the same section cover hidden-camera recordings of someone in a state of undress, which carry a much steeper felony penalty (a severity level 8 person felony, escalating to level 5 on a second conviction within five years). Those provisions have nothing to do with recording a co-parenting call, but they show how much more seriously Kansas treats covert visual surveillance than an ordinary recorded conversation.

The case that settled the rule: State v. Roudybush

Kansas's one-party rule is not just a statutory reading — it has been tested and confirmed by the Kansas Supreme Court. In State v. Roudybush, 235 Kan. 834, 686 P.2d 100 (1984), the court held that once one party to a conversation consents to it being recorded, the other party has no standing to challenge the recording. The court reasoned that a participant's consent means nothing more was captured than what that participant could have relayed afterward from memory — just a more accurate version of it. For a parent recording a co-parenting call, the practical takeaway is direct: your own presence on the call is a complete answer to a co-parent's objection that they never agreed to be recorded.

Notable exceptions worth knowing

Kansas's statute exempts messages overheard through a properly installed telephone extension or party line, recognizing that shared home phone lines are not the kind of interception the law targets. As in other one-party states, a conversation held somewhere with no reasonable expectation of privacy — a public sidewalk, a school pickup line — generally is not protected by the statute at all, meaning no one's consent is required to record it. None of these change the core rule for a parent's own calls: your participation is what matters.

Using a recording in a Kansas custody case

A call you took part in was lawfully recorded, and Roudybush forecloses the argument that your co-parent's lack of knowledge makes it unusable. That does not mean every recording gets admitted automatically: the judge still decides relevance and can weigh concerns about editing or missing context. What Roudybush and the statute both stop short of covering is a conversation you were not part of at all — for example, a device left running in a room after you have stepped out. That is outside the one-party exception and can be prosecuted as breach of privacy in its own right, and no amount of good intentions about documenting a custody dispute will convert it into a lawful recording after the fact.

The interstate caveat: when the other parent is out of state

Kansas's rule governs conduct under Kansas law, but co-parenting calls often cross state lines. States including California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania and Washington require all-party consent, and some courts apply whichever state's rule is stricter for an interstate call. If your co-parent regularly calls from one of those states, a recording that Kansas fully permits could still be questioned on their end. Announcing the recording at the start of the call closes that gap at no cost to you.

How to document a call so it holds up

Kansas law protects the recording; keeping it credible is on you. Preserve the original audio file untouched, log the date, time, and who was on the line, and never trim a clip down to the most damaging seconds before showing it to your attorney — a court that senses editing will discount the whole recording, not just the missing parts. Copareo Secure Line handles this automatically: a dedicated private number records, transcribes and time-stamps every co-parenting call into a continuous, tamper-evident archive, for a one-time $9.90 with no subscription, so there is nothing left to manually preserve or accidentally edit.

Frequently asked questions

Do I need to tell my co-parent I am recording our calls in Kansas?

No. Kansas requires the consent of only the sender or the receiver, and you count as one of them on your own call. You may record without notice, and the Kansas Supreme Court's Roudybush decision confirms the other party has no standing to object.

What did State v. Roudybush actually decide?

The Kansas Supreme Court held in 1984 that one party's consent to a recording is sufficient, and that the non-consenting party cannot challenge it, because the recording captures nothing more than what the consenting participant could have relayed from memory.

Is it legal to record a conversation I am not part of in Kansas?

No. The one-party exception only covers communications where you are the sender or receiver. Recording other people's conversation without either of them consenting falls outside the exception and can be a class A nonperson misdemeanor.

What if my co-parent lives in an all-party consent state?

Kansas itself only requires your own consent, but some courts apply the stricter state's rule to a cross-state call. If that scenario applies to you, announcing the recording removes the ambiguity.

Bottom line

In Kansas, you may lawfully record a phone call or conversation you take part in, and State v. Roudybush confirms the other party cannot challenge it just because they did not know. Keep the recording complete and unedited, avoid recording conversations you are not part of, and announce it if your co-parent is likely calling from a stricter state.
