Arizona is a one-party consent state: you may record a phone call or conversation you are part of, without telling the other parent.
A call you took part in is generally usable as evidence in an Arizona custody case, but never plant a recorder in the other parent's home, car, or bathroom — hidden recording in a private space is a separate felony under § 13-3019.

The direct answer: yes, if you are on the call
Arizona is a one-party consent state. Under Arizona Revised Statutes § 13-3005, it is unlawful to intercept a wire, electronic, or oral communication — but the statute only reaches interceptions by someone who is not a party to it. If you are a participant on the call — for example, a conversation with your co-parent about pickup times or a missed exchange — your own consent satisfies the law. You do not need to tell the other parent you are recording, and you do not need a judge’s permission.
The exact statute and what it says
Ariz. Rev. Stat. § 13-3005 requires “the consent of either a sender or receiver” for wire or electronic communications, and the consent of “a party to such conversation or discussion” for oral communications. In plain terms, one participant’s consent is enough — and if that participant is you, that is all the law demands. Federal law (18 U.S.C. § 2511(2)(d)) reaches the same one-party conclusion, so there is no gap between Arizona and federal rules for a parent recording their own calls.
The penalties are serious if you cross the line
The protection runs out the moment you record a conversation you are not part of. Intercepting a communication between other people — tapping a shared line, or capturing a call between your co-parent and someone else — is a class 5 felony in Arizona. Installing an unauthorized pen register or trap-and-trace device carries a class 6 felony. These are not minor citations: Arizona felony sentencing under §§ 13-702 and 13-801 can mean months to years in prison, on top of any civil exposure to the person you recorded.
Notable exceptions and traps for the unwary
Arizona’s consent rule for calls has a sibling statute that catches a different kind of recording entirely: § 13-3019 makes it a felony to secretly photograph, videotape, film, or digitally record another person in a bathroom, locker room, bedroom, or other place where they have a reasonable expectation of privacy, regardless of whether anyone consented to a phone recording. A parent tempted to plant a device in the other parent’s home to capture what happens there — rather than recording a call they are actually on — is not protected by the one-party rule and can be separately prosecuted. The law also carves out exceptions for law enforcement acting under a warrant and for certain communications-provider security monitoring, neither of which applies to a parent building a custody record.
Using a recording in an Arizona custody case
A call you took part in — a heated exchange about a late pickup, a threat, a broken agreement — is generally admissible in an Arizona family court proceeding, subject to the judge’s usual gatekeeping on relevance, authenticity, and whether it was obtained lawfully. Because you were a participant, there is no consent problem to litigate; the fight, if any, will be about whether the recording is complete and unaltered. Keep the original audio file untouched, note the date, time, and who was present, and resist the urge to trim it down to “the bad part” — a full, continuous recording is far more persuasive and far harder to attack than an edited clip.
The interstate caveat: what if your co-parent lives elsewhere?
Arizona’s one-party rule protects you for a call you make from Arizona, but recording law is notoriously unforgiving to interstate calls. If your co-parent is physically in an all-party consent state such as California, Illinois, or Pennsylvania when you record, that state’s prosecutors (or a civil plaintiff) can argue their law applies to a call one of its own residents was on, even though you dialed from Arizona. Courts have not settled this cleanly, and the safest practical rule is the one privacy lawyers use for any multi-state call: when you do not know, or cannot verify, where the other party is standing, treat the exchange as if the strictest rule — all-party consent — applies, and announce the recording. It costs you one sentence at the start of the call; it costs nothing else.
Beyond the call: what a strong record looks like
A single dramatic recording rarely wins a custody dispute on its own — what persuades an Arizona family court is a pattern, told through a consistent, dated record. If you are already lawfully recording calls with your co-parent under the one-party rule, treat that as one piece of a larger timeline rather than the whole case. Pair the audio with the text message thread it relates to (kept whole, never a cropped screenshot), a note of the exact date and time of the exchange, and, where relevant, who else was present or aware. Arizona courts deciding parenting time modifications under A.R.S. § 25-403 look at the “best interests of the child” factors, and a calm, factual, chronological record of missed exchanges or communication breakdowns speaks to those factors far more effectively than an angry retelling after the fact. Judges who review dozens of custody files a week can tell within a page whether a record was built as things happened or reconstructed afterward to win an argument — the former is credible, the latter rarely is. If you only have fragments — a few screenshots here, a recording there — consider going back through your phone and reconstructing the timeline as completely as you can before your next hearing, rather than presenting an incomplete picture that invites the other side to fill in the gaps with their own version of events.
Frequently asked questions
Can I record a phone call with my co-parent in Arizona without telling them?
Yes. Because you are a party to the call, your own consent is sufficient under Ariz. Rev. Stat. § 13-3005. You are not legally required to announce it, though announcing removes any later argument about consent.
Can I record my child’s conversations with the other parent if I am not on the call?
Generally no. If you are not a party to that specific conversation, recording it without consent from at least one participant can be a class 5 felony, regardless of your relationship to the child.
Will a secretly recorded call still be admissible in my custody case?
A recording you lawfully made as a participant can be admissible, but the judge decides relevance and authenticity case by case. An unedited, dated, continuously preserved recording is treated far more seriously than a short clip.
What if my co-parent is out of state when we talk?
Arizona law covers your side of the call, but the other state’s law may also apply to its resident. When you cannot confirm the other party’s location, announcing the recording keeps you safe under any state’s rule.
Arizona lets you keep the call you are on, but placing a device to capture a conversation you are not part of — the § 13-3019 line — drops you into felony territory. Copareo Secure Line keeps you firmly on the safe side: it records, transcribes, and time-stamps the calls and texts you are actually a party to, then packages them into a tamper-evident file with an admissibility one-pager your attorney can hand the court — a one-time $9.90, with no subscription.
