One-Party vs. Two-Party Consent: A Guide to Recording Laws by State

If you've ever wondered whether you need permission before hitting record, you're not alone. Recording consent laws in the United States vary significantly from state to state — and misunderstanding them can create serious legal problems.

This guide explains the difference between one-party and two-party (all-party) consent states, lists which category each state falls into, and covers what this means for anyone using a voice recorder in everyday situations.

This article is for informational purposes only and is not legal advice. Consult a qualified attorney in your jurisdiction for guidance specific to your situation.

What Is "Consent" in Recording Law?

When it comes to audio recording, consent refers to whether the people being recorded have agreed to it. Federal law — specifically the Electronic Communications Privacy Act (ECPA) — sets a national baseline that requires at least one party to the conversation to consent to the recording.

Many states go further and require all parties to consent. Understanding which rules apply to you depends on where you are and where the other parties to the conversation are located.

One-Party Consent States

In a one-party consent state, only one person involved in the conversation needs to consent to the recording. That one person can be you — meaning you can record a phone call or in-person conversation you're part of without telling the other person.

One-party consent generally applies in most U.S. states, including:

• Alabama
• Alaska
• Arizona
• Arkansas
• Colorado
• Georgia
• Hawaii
• Idaho
• Indiana
• Iowa
• Kansas
• Kentucky
• Louisiana
• Maine
• Minnesota
• Mississippi
• Missouri
• Nebraska
• New Jersey
• New Mexico
• New York
• North Carolina
• North Dakota
• Ohio
• Oklahoma
• Oregon
• Rhode Island
• South Carolina
• South Dakota
• Tennessee
• Texas
• Utah
• Virginia
• West Virginia
• Wisconsin
• Wyoming

Note that even in one-party consent states, there are exceptions — particularly for recording in places where someone has a reasonable expectation of privacy, or when the recording is used for illegal purposes.

Two-Party (All-Party) Consent States

In two-party or all-party consent states, everyone participating in a conversation must give their consent before it can be recorded. Recording without all-party consent in these states can be a criminal offense.

All-party consent is required in:

• California
• Connecticut
• Delaware
• Florida
• Illinois
• Maryland
• Massachusetts
• Michigan
• Montana
• Nevada
• New Hampshire
• Pennsylvania
• Washington

A few states — including Oregon and Illinois — have more nuanced rules or conflicting interpretations in their case law, so even states that appear on one list may have exceptions depending on context. Always verify current law in your state.

What About Cross-State Calls and Meetings?

When people in different states are on the same call or video meeting, things get more complicated. (If you're recording meetings specifically, see our guide on choosing a recorder for meetings.) The most conservative approach — and often the safest legally — is to follow the strictest applicable law. If one person on a call is in California (an all-party consent state), many attorneys recommend treating the entire call as requiring all-party consent.

This is especially relevant for:

• Remote work meetings with participants across multiple states
• Phone sales calls originating in one state to customers in another
• Legal or HR interviews conducted by video

Common Scenarios and What They Mean

Recording a Meeting at Work

In a one-party consent state, you can generally record a meeting you're attending without notifying others. In an all-party consent state, all attendees must consent. Many employers also have their own policies about recording in the workplace — always check those as well.

Recording a Phone Call

Same rules apply: in one-party states, you can record your own calls. In all-party states, you must tell the other party. Many call centers and businesses address this proactively with announcements like "This call may be recorded."

Recording a Conversation Without Participating

This is where recording laws get strict almost everywhere. If you're not a party to the conversation, recording it typically requires consent from all participants — even in one-party consent states — because you're not the "one party" consenting.

Recording in Public

Recording in public spaces is generally permitted when people don't have a reasonable expectation of privacy. Street conversations, public speeches, or interactions in open spaces are typically fair game. However, even in public, recording conversations that are clearly private (a hushed discussion between two people on a park bench) may still raise legal issues depending on the state.

How This Applies to Voice Recorders

A voice activated recorder is simply a tool — the laws described above apply regardless of what device you use to record. Whether it's a smartphone, a digital voice recorder, or a dedicated voice activated recorder, the consent requirements are the same.

That said, certain recorder form factors naturally lend themselves to more discreet recording (see our guide to discreet voice recorder options) — and it's worth noting that the legality of a recording depends on the consent of the parties, not on whether they can see the recorder. A device that looks like a pen is no different legally than a visible one.

A Quick Reference Summary

Here's a simplified breakdown for common situations:

• One-party state, you're part of the conversation: Generally legal to record without disclosure
• All-party state, you're part of the conversation: Must notify and get consent from all parties
• You're not part of the conversation: Generally requires consent from all parties regardless of state
• Cross-state call: Follow the strictest applicable state law to be safe
• Public space, no expectation of privacy: Generally permitted

Bottom Line

Understanding recording consent laws isn't just about avoiding legal trouble — it's about using these tools responsibly. Most legitimate uses of a voice recorder (documenting meetings, keeping personal notes, recording interviews with permission) don't raise issues under any state's law. But understanding the rules helps you stay informed wherever you are.
