Wyoming is a one-party consent state: you may record a call or conversation you are part of without telling the other parent.
A recording you took part in is generally usable in a Wyoming custody matter, subject to the judge's discretion on relevance and how it was obtained. Recording a call you are not on is a felony.

Short answer: yes. Wyoming is a one-party consent state. If you are a participant in the call — a custody dispute over the phone, a handoff conversation, a voicemail left for you — you can record it yourself, without telling the other person and without announcing it in advance.
What one-party consent means in Wyoming
Under Wyoming Statutes § 7-3-702, it is generally unlawful to intercept, disclose, or use a wire, oral, or electronic communication, but the statute exempts “any person from intercepting an oral, wire or electronic communication where the person is a party to the communication or where one of the parties to the communication has given prior consent to the interception,” unless the interception is made “for the purpose of committing any criminal or tortious act.” Because you are always a party to your own call, your consent alone satisfies the statute — you do not need the other parent to agree or even to know. This mirrors the federal wiretap act, 18 U.S.C. § 2511(2)(d), which sets the same one-party floor nationwide.
The penalty if you get it wrong
The participant exception protects only conversations you are actually part of. A general violation of § 7-3-702 — tapping a line you are not on, hiding a device, or otherwise intercepting a conversation between other people — is a felony punishable by a fine of up to $1,000, imprisonment for up to five years, or both. A narrower, reduced penalty applies to a specific category of radio-based intercepts (the unencrypted radio portion of a cellular call, a cordless-handset signal, public land mobile radio, or paging service): those are misdemeanors punishable by a fine of up to $750, imprisonment for up to six months, or both. Neither penalty touches you as a participant recording your own call — the exposure is for listening in on conversations you have no part in.
Exceptions and nuances worth knowing
Wyoming's statute treats phone calls, oral conversations, and electronic communications under a single one-party rule, so the same logic applies whether the dispute plays out over a phone call or an in-person exchange captured with a recording device at a custody handoff. The “criminal or tortious purpose” limitation still matters: even as a participant, recording specifically to extort, harass, or otherwise commit an unlawful act against the other party can strip away the one-party protection. For an ordinary parent documenting a custody-related conversation for its own sake, the exception applies cleanly.
Recording calls in a Wyoming custody dispute
A call or conversation you took part in is generally usable in a Wyoming family court matter, but admissibility is always decided by the judge, who weighs relevance, authenticity, and how the recording was obtained. Keep the original audio file intact and unedited: a trimmed or “cleaned up” recording is far easier for the other side's attorney to challenge, and can damage your credibility on everything else you present. If you ever intercept a conversation you were not part of, do not bring it into a custody proceeding — it was obtained unlawfully and exposes you to felony liability instead of helping your case.
What makes a recording admissible, not just legal
Being allowed to record a call and getting a Wyoming court to actually rely on it are two different hurdles. Judges weighing a custody dispute look past the legality question to ask: were you really a party to the call; is the file complete, unedited, and free of gaps; can you account for every step from the moment you hit record to the moment you handed it to the court; and does an independent timestamp back up when it happened. Skip any one of these and even a perfectly legal recording can get picked apart on cross-examination.
Crossing state lines: the interstate caveat
Wyoming borders states with different consent rules, including Montana, an all-party consent state. If your co-parent is calling from Montana or another all-party state, the prudent approach is to follow the stricter of the two states' rules and announce that the call is being recorded, rather than relying solely on Wyoming's one-party rule. The other party's home state may apply its own consent law to that specific call, and an announced, dated recording is lawful everywhere — a silent recording of someone in an all-party state creates legal exposure you do not need to take on.
How to document it so it holds up
Parents who win on documentation rarely produce one dramatic recording — they build a running, dated file as the conflict unfolds: full calls kept intact rather than clipped, whole text threads instead of screenshots, everything stored somewhere it cannot vanish with a lost or reset phone. That ongoing habit is exactly what Copareo Secure Line supports — it time-stamps every call with a tamper-evident method and compiles the whole record into one court-ready file, for a one-time $9.90 with nothing to renew or cancel.

Frequently asked questions
Can I record a phone call with my co-parent in Wyoming without telling them?
Yes. Wyoming requires the consent of only one party to the call, and as a participant your own consent satisfies the statute. Announcing the recording is never unlawful, but it is not required.
Is it illegal to record a conversation I am not part of in Wyoming?
Yes — unlawful interception under § 7-3-702 is generally a felony, punishable by up to five years' imprisonment and a $1,000 fine. Only record calls and conversations you are actually taking part in.
Can a phone recording be used in a Wyoming custody case?
Yes, if it was lawfully captured under § 7-3-702 and a Wyoming judge finds it relevant and trustworthy. Keep the original file intact — the court alone decides admissibility, weighing relevance and authenticity case by case.
What if my co-parent lives in Montana?
Treat the call as if Montana’s stricter all-party rule applies, and say out loud that you’re recording before the conversation starts. That keeps the recording lawful no matter which state’s law a court later decides governs the call.
Does the one-party rule cover text messages the same way?
Text messages you send or receive are already lawfully yours — there is no interception question the way there is for a live call. The real risk with texts is preservation, not consent: export the full thread with intact timestamps rather than relying on a cropped screenshot that can be questioned or altered.
Bottom line
In Wyoming, you may lawfully record a phone call or conversation you are part of, and a complete, unedited, clearly dated recording can support a custody case far better than a pile of screenshots or a half-remembered argument. Never intercept a conversation you are not part of, and when a call crosses into a neighboring all-party state, the safer move is to announce it rather than assume Wyoming's rule follows you across the border.
