Idaho is a one-party consent state: you may record a phone call or conversation you are part of, without telling the other person.
A recording you took part in is generally admissible in an Idaho custody case, but recording a conversation you are not part of — or one nobody consented to — is a felony, not evidence.

The short answer: Idaho is a one-party consent state
If you are an Idaho parent wondering whether you can record a call with your co-parent, the answer is yes. Idaho requires the consent of only one party to a wire, electronic or oral communication, and because you are a participant in your own call, your consent is all the law asks for.
What the statute actually says
The rule is in Idaho Code § 18-6702, Idaho’s communications-security statute. Subsection (1) makes it unlawful to willfully intercept, or procure someone else to intercept, a wire, electronic or oral communication. But subsection (2)(d) carves out the exception that matters here: “It is lawful under this chapter for a person to intercept a wire, electronic or oral communication when one of the parties to the communication has given prior consent to such interception.” Because you are that party, your own consent satisfies the statute, and you do not need the other party to agree or even to know.
Idaho’s rule mirrors the federal wiretap act. Under 18 U.S.C. § 2511(2)(d), a person who is a party to a communication may lawfully intercept it, so long as the purpose is not criminal or tortious. Idaho and federal law both set the bar at one-party consent, so a parent recording their own co-parenting call is covered by both statutes at the same time.
The penalty for getting it wrong
Willfully intercepting a communication without any party’s consent is a felony under § 18-6702, punishable by up to five years in the state penitentiary, a fine of up to $5,000, or both. That is meaningful exposure for planting a device to catch a conversation you are not part of, or for recording a line neither party has agreed to have intercepted — but it does not touch a recording you make of your own conversation.
Notable exceptions and limits
Idaho’s one-party consent rule tracks the federal wiretap act closely, including a similar carve-out for law enforcement acting with a party’s consent. For a private individual, though, the exception that matters is simple: you must actually be a party to the communication, or have the consent of a party, before you record it. Idaho courts have also recognized that a person generally has no reasonable expectation of privacy in a conversation happening where others can freely hear it, which is a separate line of reasoning from the consent statute itself but reinforces that Idaho does not treat ordinary, openly-conducted conversations as off-limits to record.
Using a recording in an Idaho custody case
A recording you made as a participant is generally admissible in an Idaho custody or divorce case, subject to the same relevance and authenticity rules that apply to any evidence. As elsewhere, an unedited, continuously recorded, clearly dated conversation is far more persuasive — and far harder to challenge — than a short clip presented without context. Preserve the original audio, log the date and participants, and let your attorney decide how it fits into your broader case.
Recording across state lines: the strictest-rule caveat
Idaho’s one-party rule governs calls under Idaho law, but if your co-parent is in an all-party state like Washington, Montana or California during the call, that state’s stricter rule could also apply. When a call might cross state lines, the safer habit is to assume the strictest applicable rule governs and announce the recording rather than relying on Idaho’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
Treat a single Idaho recording as one piece of a larger, consistent record rather than the whole case. Preserve full text threads instead of cropped screenshots, keep the original, unedited audio file, and attach a reliable date and time to everything you save. Store copies somewhere you control — a cloud folder or a dedicated archive, not just the phone you recorded on — so nothing disappears with a lost device or a software update. A continuous, dated history across weeks or months is what turns a single call into real evidence of a pattern.
Frequently asked questions
Can I record a phone call with my co-parent in Idaho without telling them?
Yes. As a party to the call, your consent under § 18-6702(2)(d) is enough on its own.
Can I record a conversation I am not part of?
No, not without the consent of at least one participant. Doing so is a felony under § 18-6702, punishable by up to five years in prison and a fine of up to $5,000.
Does it matter if I only record part of the call?
Legally, partial and full recordings are treated the same for consent purposes, but a partial or edited recording is much more likely to be challenged as unreliable or misleading in court.
Will an Idaho judge automatically admit my recording?
No. Being lawfully made under § 18-6702 does not guarantee admissibility; the judge still weighs relevance, completeness and reliability.
Can my co-parent record our calls too, without telling me?
Yes. Idaho’s one-party rule applies equally to both parents: whoever is on the call can record it as a participant, regardless of who the other person is.
Do I need to keep the original recording file, or is a transcript enough?
Keep the original audio file whenever possible. A transcript can help a judge or attorney review the content quickly, but the original recording is what actually gets authenticated as evidence.
What if the call involves a co-parent who lives in a different, stricter state?
Idaho’s one-party rule only guarantees that your own side of the call is lawful under Idaho law. Check the rule for wherever your co-parent is physically located before assuming the whole call is covered by Idaho’s standard alone.
Is recording a group text or a family group chat treated the same as a phone call?
Group texts and chat apps are not “intercepted” the way a live call is, so § 18-6702’s consent-to-record rule does not squarely apply to them. Saving and preserving that written record raises different, mostly simpler, evidentiary questions than an audio recording does.
Can I record a mediation session or a court-ordered custody evaluation call?
Treat any recording connected to a court process as a special case: mediation confidentiality rules and court orders can restrict recording even where § 18-6702’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 Idaho, 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.
