Call Recording Laws in Hawaii

Short answer: Yes. Hawaii is a one-party consent state. Under Haw. Rev. Stat. § 803-42, you can legally record a phone call you are part of without telling the other people on the call. Recording a conversation you are not part of, without a participant’s consent, is illegal.

Plain-English summary

Hawaii is a one-party-consent state. Haw. Rev. Stat. § 803-42 prohibits intercepting a wire, oral, or electronic communication; § 803-42(b)(3) provides a participant exception.

A participant may record an ordinary phone call in Hawaii without notifying the other party.

Case law of note

No appellate decision in Hawaii has materially reshaped the participant-recording rule in recent decades. Lower-court decisions exist but do not change the analytical framework set by the statute and by general federal precedent under § 2511.

Edge cases and special rules

  • In-person vs. phone. Same — one-party
  • Voicemail. Leaving a message creates the recording at the recipient’s direction; reviewing one’s own voicemail is not interception.
  • Vicarious consent. Several federal courts have recognized a parental-consent doctrine permitting a parent to consent on behalf of a minor child (Pollock v. Pollock, 154 F.3d 601 (6th Cir. 1998)). State law varies; no controlling Hawaii appellate decision on the question.
  • Law enforcement. Court-authorized intercepts are governed by a separate framework and are outside the scope of this page.
  • Cross-border calls. Where any participant is in an all-party state, treat the stricter rule as the safer default. See cross-border calls.

Penalties and remedies

Criminal: Class C felony under § 803-44.

Civil: Yes — § 803-48 provides civil remedies.

Evidence: a recording made in violation of the Hawaii statute is generally inadmissible in Hawaii proceedings. Federal § 2515 separately bars use of unlawfully intercepted communications in federal proceedings.

Practical guidance

  • If you are recording an ordinary phone call: you may record without notifying the other party, but verbal consent is the safer practice if the recording may be used in a proceeding.
  • Suggested opening: See our consent script templates for jurisdiction-specific language.
  • If the other party objects: stop recording. Continued recording over an objection is a separate factual question that no consent statute helps you with.
  • What to keep: the date and time of the call, the parties’ phone numbers, a description of the consent given (express verbal, continued participation after notice, etc.), and the audio file itself.

Frequently asked questions

Is Hawaii a one-party consent state?

Yes. Hawaii is a one-party consent state. Under Haw. Rev. Stat. § 803-42, you can legally record a phone call you are part of without telling the other people on the call. Recording a conversation you are not part of, without a participant’s consent, is illegal.

Can I record a phone call in Hawaii without the other person knowing?

Yes, if you are a participant in the call. Hawaii law does not require you to tell the other party. Announcing the recording is still the safer practice if it may be used in court, or if anyone on the call is in an all-party consent state.

Does the same rule apply to in-person conversations in Hawaii?

Yes. Hawaii applies the same one-party rule to in-person conversations.

What is the penalty for illegally recording a call in Hawaii?

Criminal: Class C felony under § 803-44. Civil: Yes — § 803-48 provides civil remedies.

Can a phone recording be used as evidence in Hawaii?

A recording made in violation of Hawaii law is generally inadmissible in Hawaii proceedings, and federal law (18 U.S.C. § 2515) bars unlawfully intercepted communications in federal proceedings. A lawfully made recording can be admissible, but it must still be authenticated and relevant — ask a lawyer before relying on one.

What if the other person on the call is in a different state?

When a call crosses state lines, courts may apply the stricter state’s law. If anyone on the call is in an all-party consent state such as California, Florida or Illinois, get everyone’s consent before recording. See cross-border calls.
