Is It Legal to Record Someone in Idaho? What One-Party Consent Allows

01The basic rule

Idaho Code § 18-6702 and the One-Party Consent Exception

Idaho's eavesdropping statute, Idaho Code § 18-6702, makes it a crime to willfully intercept a wire, electronic or oral communication, or to procure anyone else to do it. The same section reaches using a device to intercept, disclosing what was captured, and using the contents. As of the 2026 Idaho Code, the penalty is a felony punishable by up to five years in state prison, a fine of up to $5,000, or both. The section was added in 1980 and amended in 2002 and 2004.

The key exception sits in subsection (2)(d). An interception is lawful when one of the parties to the communication has given prior consent. In practice that means a person who is part of a call, a meeting or a face-to-face conversation can generally record it without telling anyone else. Lawyers call this one-party consent, and it is the reason most people can lawfully record someone in Idaho when they are speaking with that person directly. Our Idaho investigations overview explains how Delator applies the rule in field work.

The word prior matters. Consent has to exist before the recording starts, and the consenting person has to be a real participant, not a bystander who happened to be in the room. If you are unsure whether you count as a party, stop and ask counsel before you record. Our Idaho attorney support team regularly helps lawyers evaluate how a client's recording was made.

• Felony: up to 5 years and $5,000
• One party's prior consent generally suffices
• Covers wire, electronic and oral communications

02Where it becomes a crime

Recording Conversations You Are Not Part Of

The exception protects participants, not eavesdroppers. Leaving a phone running in a kitchen to capture a spouse's call, hiding a recorder in a car you share, or installing a listening device in an office you do not control are the situations that turn an ordinary dispute into a felony investigation. If no participant consented, the one-party exception does not apply, however good your reasons may feel.

The statute also covers procuring another person to intercept. That language matters when people try to hire help. An investigator who agrees to bug a home, a vehicle or a hotel room on a client's behalf is not a loophole; the client who asked may share the exposure. Delator Group refuses that work. When a client needs proof of conduct, we turn to lawful surveillance investigations in Idaho from public places instead.

Disclosure and use carry their own risk. Even if you did not make an unlawful recording, knowingly sharing or relying on one that was unlawfully made can raise problems under the same section. Before you circulate a recording in a family group chat or post it online, talk to counsel. If you suspect someone has recorded you without consent, our stalking and harassment investigators can document what is happening for a report or petition.

03Phones, texts and apps

Call Recording, Spyware and Electronic Messages

Recording your own phone call through a built-in feature or app generally falls under the one-party rule. The harder cases involve other people's devices. Installing monitoring software on a partner's phone, reading messages by logging into their accounts, or forwarding their texts to yourself can implicate § 18-6702 because the statute reaches electronic communications, not just spoken words. It can also create stalking exposure. Our cyberbullying investigations in Idaho show the lawful way to preserve harmful messages.

Idaho Code § 18-7906 defines second-degree stalking to include following someone or maintaining surveillance on them, including by electronic means, as part of a course of conduct that would cause a reasonable person substantial distress. Covert apps and location sharing a person never agreed to fit uncomfortably close to that language. Separately, § 18-6710 makes harassing electronic communications, including email and text, a misdemeanor on a first offense and a felony on a second or later offense.

If you are on the receiving end, screenshots with visible dates, saved voicemails and exported message threads are generally lawful to keep because you were a party to them. Preserve the originals, avoid editing or cropping, and note where each file came from. A workplace harassment investigation or a protection order petition goes further with a clean record of what arrived and when, and an elder scam investigation often turns on the same kind of saved calls and texts.

04Calls that leave Idaho

Calls Into Washington and Other All-Party States

Idaho's rule does not travel with you. Washington's privacy statute, RCW 9.73.030, generally requires the consent of all participants before a private conversation is recorded. That matters across the Panhandle and the Palouse, where daily life runs between Coeur d'Alene and Spokane, Moscow and Pullman, and Lewiston and Clarkston. A Kootenai County resident recording a call with someone in Spokane may face Washington law as well as Idaho law. Clients near the state line can reach our Post Falls investigators for local guidance.

Federal law adds a third layer. The federal wiretap statute generally allows one-party recording as well, unless the recording is made for a criminal or tortious purpose. Courts in different states have handled interstate calls in different ways, and no single rule settles every case. The safest course is to assume the strictest state involved applies until your attorney tells you otherwise, and to write down where each person was when the call took place.

Investigators face the same issue. Delator does not record calls with witnesses or subjects in all-party states without their agreement, and we note the location of every participant in the case file so counsel can see which law applied. For matters on the Palouse, our Moscow private investigators coordinate with attorneys on both sides of the state line, and the same care applies to calls into Oregon, Montana or Utah.

05Video and hidden cameras

Hidden Cameras, Doorbells and Idaho's Voyeurism Statute

Video without sound is a different question from audio interception, but it is not a free pass. Idaho Code § 18-6605, renumbered from § 18-6609 in 2022 and amended again in 2026, makes it a felony to use or install an imaging device where a person has a reasonable expectation of privacy, without their knowledge or consent, for purposes such as sexual gratification or degradation. It also covers distributing or threatening to distribute intimate images of an identifiable person to harass or humiliate them.

Home security cameras are common and generally lawful on your own property, but placement and audio matter. A camera pointed into a neighbor's bedroom window, or one hidden in a bathroom or guest room, can create exactly the expectation-of-privacy problem the statute addresses. Many doorbell and indoor cameras also capture sound, and audio of conversations you are not part of brings § 18-6702 back into the picture. Turn audio off unless you have thought it through.

Investigators observe and photograph from places the public can lawfully be, such as streets and parking lots, and they do not enter posted or private land without permission. That keeps video useful in court rather than a liability. If you are worried that someone has placed a camera on you, our personal information protection service and lawful workplace surveillance reviews can help you find out what is being collected.

06Divorce and custody

Using Recordings in Idaho Divorce and Custody Cases

In Idaho, divorce and custody matters are generally heard in the magistrate division of the district court. Judges weigh the best-interest factors in Idaho Code § 32-717, including the child's relationships, adjustment and stability, and domestic violence whether or not it occurred in the child's presence. A lawful recording of a threat made directly to you may be relevant to those factors. Whether it comes into evidence, and how it is authenticated, is a decision for your Idaho divorce or custody attorney to make.

Unlawful recordings can backfire badly. A parent who bugs the other household or secretly records the other parent's calls with a new partner may hand the opposing side an argument about judgment and character, and may face a criminal referral. Recording a child's phone calls raises its own unsettled questions, so get advice before you try it. Our guide to custody investigations in Idaho explains the lawful alternatives in detail.

Corroboration usually matters more than a single clip. An investigator can document exchanges, living conditions and conduct through lawful observation and public records, which gives the judge something more than one parent's recording to weigh. If an affair is part of the picture, a properly scoped infidelity investigation builds that record without touching the other spouse's phone, car or accounts.

07How we work

How Delator Investigators Gather Evidence Without Illegal Recording

Our investigators record only conversations they are part of, and only where every relevant state's law allows it. Witness interviews are recorded openly with the witness's agreement or documented in written notes. Surveillance is conducted from public vantage points and logged by date, time and location, with photographs and video tied to the log. We do not install devices on property the client has no right to, and we do not access accounts.

That discipline is what makes the work usable. Defense attorneys and civil litigators need evidence that survives a suppression motion or a challenge to authenticity, and family law clients need reports a magistrate will credit. Delator bills investigative work in Idaho at $100 per hour, and the Idaho service pricing page lists case minimums. Before you hire anyone, our checklist for vetting an Idaho investigator tells you which recording questions to ask.

If you already have a recording and are unsure whether it was lawful, do not delete it and do not share it with anyone. Bring it to your attorney first and explain how it was made. We can then help counsel evaluate it and build independent evidence around it through an investigative case review. Where a recording points to a crime against a business, our corporate espionage investigations take the matter further lawfully.

How it works

Before You Press Record in Idaho

1. 01

   Confirm you are a party

   Make sure you are an actual participant in the conversation, not a listener in the next room, and that your consent exists before the recording begins.

2. 02

   Check every location

   Find out where each participant is. A caller in Washington or another all-party state can change the rule, so assume the strictest law applies until advised.

3. 03

   Avoid other people's devices

   Do not install apps, cameras or recorders on phones, cars or rooms you do not control, and do not log into another person's email, cloud or social media accounts.

4. 04

   Preserve and ask counsel

   Keep the original file unedited, write down when and how it was made, and let your attorney decide whether and how it is used in court.
