Is It Illegal to Record a Conversation?

Recording a conversation is legal in most of the United States as long as one person in the conversation agrees to it. That person can be you. Federal law and roughly 38 states follow this one-party consent rule.

The catch is the other states. About a dozen require that everyone in the conversation consent before it is recorded. Record a call with someone in one of those states and you may break the law, even if you are on the call yourself.

This guide explains the difference, how it changes across in-person talks, phone calls, and video meetings, and why AI note-takers have made the question urgent again. The answer is rarely a flat yes or no. It turns on where each participant sits, what medium you use, and whether the conversation was private.

This is general information, not legal advice. Consult a qualified attorney about your specific situation before you record.

One-party Consent vs. All-party Consent

One-party consent means the recording is legal if at least one participant agrees. All-party consent means every participant must agree first. That single distinction decides most recording questions.

Federal law sets the floor at one-party consent. Under the federal Wiretap Act, you can record a communication you are part of, or one where a party has consented. States are free to demand more protection, and about a dozen do.

When a conversation crosses state lines, the safest assumption is that the strictest state's law could apply. A one-party-state caller and an all-party-state listener can create real legal risk.

• One-party consent: one participant (including you) can authorize the recording.
• All-party consent: every participant must be told and must agree.
• Federal baseline is one-party; states can raise the bar, not lower it.

What Federal Law Says (ECPA and the Wiretap Act)

Federal law permits recording when you are a party to the conversation or one party has given consent. This rule comes from the Electronic Communications Privacy Act, which amended the older federal Wiretap Act at 18 U.S.C. § 2511.

The statute carries an important limit. The one-party exception does not apply if the recording is made to commit a crime or a tort. Courts in the Ninth Circuit read that criminal-or-tortious-purpose exception narrowly, so the intent has to be genuinely unlawful, not just self-interested.

Federal penalties are serious. Illegal interception can bring fines and up to five years in prison, plus civil liability. But federal law is only the floor. State law is where most people get tripped up.

Where State All-party Consent Laws Apply

A group of states requires consent from every participant. These are the all-party (often called two-party) consent states, and they include California, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania, and Washington.

Several more are mixed. Connecticut, Nevada, Oregon, and Michigan apply all-party rules in some situations and one-party rules in others, often splitting between phone calls and in-person talks. Michigan courts read its statute to let a participant record their own conversation.

California is the model most people cite. Its Invasion of Privacy Act, at Penal Code § 632, makes it illegal to record a confidential communication without everyone's consent. A confidential communication is one where the parties reasonably expect privacy.

• Clear all-party states: California, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania, Washington.
• Mixed or nuanced: Connecticut, Nevada, Oregon, Michigan.
• Everywhere else, plus federal: one-party consent.

In Person, Phone, and Video Meetings Are Treated Differently

The medium can change the rule inside a single state. Oregon requires all-party consent for in-person conversations but allows one-party consent for phone calls. Connecticut runs the opposite way for telephone recordings.

Video meetings are the newest wrinkle. A Zoom, Google Meet, or Teams call with participants in several states can pull in the strictest state's law. Platform vendors know this, which is why most now show a visible recording banner.

A recorded video meeting is still a recorded conversation. The same consent analysis applies, whether a human clicks record or an automated tool captures the audio in the background.

Why AI Note-takers Make This a Live Question

AI note-takers record and transcribe meetings automatically, and many join without an obvious visible presence. That silent capture is exactly what consent laws were written to police.

Tools like Granola, Otter, Fireflies, and Fathom listen to a meeting and produce a summary. Some send a labeled bot into the call. Others, including Granola, capture audio on the user's own device without a visible bot, which makes notice to other participants harder.

This design is now being tested in court. A putative class action, Chamberlain v. Granola, Inc., filed in the Northern District of California in July 2026, alleges the tool recorded conversations and used captured communications to train AI models by default. The complaint is early-stage and unproven, and parallel suits have been filed against Otter.ai and Fireflies.ai. The core federal theory rests on the Wiretap Act, with state claims under laws like California's CIPA.

• AI note-takers can record without a clearly visible presence.
• Silent, on-device capture makes participant notice harder.
• Litigation is testing whether default recording and training violate consent laws.

How to Record Without Breaking the Law

Announce the recording at the start and get a clear yes. A spoken confirmation, a checkbox, or a persistent on-screen banner all help show consent was given.

When participants span multiple states, apply all-party rules across the board. It is simpler than mapping each person to a jurisdiction, and it protects you if someone travels.

For AI note-takers specifically, do not rely on the tool's defaults. Confirm what it records, whether it uses your data for training, and whether other participants ever see a notice. Those settings decide your exposure.

• Give clear notice and capture affirmative consent before recording.
• Default to all-party consent on any multi-state call.
• Audit your note-taker's recording, notice, and training settings.

Recording at Work Carries Extra Rules

Employers face a second layer beyond consent law. Recording employees can collide with labor rules, and secretly recording a workforce can chill protected activity such as discussing pay or organizing.

Employees recording their own workplace face the same consent map as anyone else. In a one-party state, an employee can usually record a meeting they attend. In an all-party state, they generally cannot record coworkers or managers without consent.

Company policy does not override statute. A handbook that bans recording still cannot make a one-party-state recording illegal, and a policy that permits recording cannot cure an all-party violation. Both employer and employee should know which state's law governs the call.

• Secretly recording staff can trigger labor-law problems.
• Employees follow the same one-party or all-party map as anyone.
• Company policy cannot override the governing state statute.

What Happens If You Record Illegally

Illegal recording can be both a crime and a civil wrong. Federal law allows criminal penalties and civil damages. State statutes add their own fines, and some make unauthorized interception a felony.

Private lawsuits are often the bigger business risk. Several all-party states let a person sue for statutory damages per violation, which multiplies fast across many recorded meetings. A single misconfigured note-taker across hundreds of calls can turn one mistake into a large exposure.

An illegally made recording can also be thrown out as evidence, so a recording meant to protect you can end up useless. When money, employment, or litigation is on the line, get advice from qualified counsel before you record.
