North Dakota is a one-party consent state: you may record a call or conversation you are part of, without telling the other person.
A recording you took part in is generally usable in a North Dakota custody matter, subject to the judge's view of relevance and authenticity. The statute's 'wire communication' wording is tied to common-carrier lines, so its reach to cellphone calls isn't fully settled — treat every call as covered anyway.

What one-party consent means in North Dakota
North Dakota is a one-party consent state. Under N.D. Cent. Code § 12.1-15-02 (titled “Interception of wire or oral communications — Eavesdropping”), a person is guilty of a felony if they intentionally intercept a wire or oral communication by an electronic or mechanical device. But the same section builds in a defense: it is a defense to prosecution that “the actor was a party to the communication or one of the parties to the communication had given prior consent to such interception,” provided the communication was not intercepted to commit a crime or other unlawful harm. Because you are on your own call, your consent is legally sufficient — you are not required to tell the other parent you are recording.
Federal law reaches the same place: under 18 U.S.C. § 2511(2)(d), a participant to a communication may record it so long as the purpose is not criminal or tortious. North Dakota's rule for calls and its rule for in-person conversations both flow from the same section, so the one-party analysis is consistent whether the conversation happens by phone or face-to-face.
The penalty is a felony, with a separate misdemeanor for a different offense
Unlawfully intercepting a wire or oral communication is generally a Class C felony in North Dakota, carrying up to five years in prison, a $10,000 fine, or both. The same statute separately criminalizes something different — secretly loitering around a building to overhear a conversation and then repeating or publishing it to “vex, annoy, or injure others” — as a Class A misdemeanor. That second offense is about physical eavesdropping-and-gossip, not about recording your own calls, but it is worth knowing the statute covers both behaviors under one section, because a lawyer or the other side may reference either provision.
A scope quirk worth knowing: what counts as a “wire communication”
North Dakota's definitions section (§ 12.1-15-04) defines a covered “wire communication” as one made “through the use of facilities for the transmission of communications by the aid of wire, cable, or other like connection … furnished or operated by any person engaged as a common carrier.” Because that language is tied to physical, common-carrier-provided lines, it is not entirely settled whether a cellphone-to-cellphone call or a text message between wireless devices falls squarely within the statute's protection the same way a landline call does — North Dakota courts have not clarified the point. The safe, prudent reading for a parent documenting a co-parenting conflict is not to lean on that ambiguity: treat every call and text, cellphone included, as governed by the one-party consent rule, and only record conversations you are actually part of.
Where the participant defense stops
The defense in § 12.1-15-02(3)(c) only protects you when you are actually a party to the communication, or when a party has given prior consent. Recording a conversation between two other people, or tapping a line you are not on, falls entirely outside the defense and exposes you to the full felony penalty. And the defense evaporates if the communication was intercepted “for the purpose of committing a crime or other unlawful harm” — a participant recording made to set up harassment or extortion is not protected just because you were on the call.
Using a recording in a North Dakota custody case
A phone call you took part in is generally usable as evidence in a North Dakota domestic-relations matter, but the judge decides admissibility, weighing relevance and authenticity. Keep the original audio file untouched, log the date, time, and who was on the call, and never edit or trim the recording — an altered file invites a credibility challenge that can spill over into the rest of your case. A complete, unedited, clearly dated recording of your own conversation carries far more weight than a short, out-of-context clip.
Calling a co-parent in another state? Follow the stricter rule
North Dakota's one-party rule only governs what happens under North Dakota law. If your co-parent is physically located in an all-party consent state — California, Illinois, Michigan, and others — when you call, that state's stricter consent requirement may apply to the same conversation, and it is not always obvious which state actually controls a cross-border call between cellphones. When you cannot be sure where the other parent is, the safest and most litigation-proof habit is to assume the strictest applicable rule — all-party consent — and announce that you are keeping a record. An announced, dated archive is lawful everywhere, regardless of which state's law technically governs.
How to document it so it holds up
Beyond the recording itself, the strongest record is consistent and complete: preserve full message threads rather than cropped screenshots, attach a verifiable date and time to every entry, and keep a copy somewhere your co-parent cannot alter or delete. A continuous, time-stamped history of your exchanges is far harder for the other side to dispute in front of a North Dakota judge than a single recording presented without context around it.
Bottom line
In North Dakota, you may lawfully record a call or conversation you are part of without announcing it, and a lawful, well-preserved recording can support your case. Never record a conversation you are not part of — that is a felony — and when a call might cross state lines or involve cellphones under an unsettled point of law, the safer habit is to announce it anyway.
Do I need to tell my co-parent I am recording our call in North Dakota?
No. As a party to the call, your own consent is a defense under § 12.1-15-02(3)(c). You are not legally required to announce it, though announcing remains the safer choice if the call might cross into a state with a stricter rule.
What happens if I record a conversation I am not part of?
That falls outside the participant defense entirely and is generally a Class C felony in North Dakota, exposing you to up to five years in prison and a $10,000 fine. Only record calls and conversations you are actually taking part in.
Does North Dakota's recording law clearly cover cellphone calls?
The statute's definition of a protected “wire communication” is tied to lines furnished by a common carrier, and North Dakota courts have not fully clarified how that applies to cellphone-to-cellphone calls. The prudent approach is to treat cellphone calls the same as landline calls under the one-party rule rather than rely on the ambiguity.
Can I use a phone recording against my co-parent in a North Dakota custody case?
Yes, a lawful recording you took part in can generally be offered as evidence, but the judge decides what comes in based on relevance and authenticity. Keep the original file unedited and note the date, time, and participants so it holds up under scrutiny.
