Are Voice Recorders Legal? What You Need to Know

Before using any audio recording device, it’s important to understand the legal landscape.

One-Party vs Two-Party Consent

In the United States, recording laws generally fall into two categories:

One-party consent states:
  Only one person involved in the conversation needs to consent to the recording.

Two-party (all-party) consent states:
  Everyone involved in the conversation must agree to be recorded.


Why This Matters

If you are in a one-party consent state, you can legally record a conversation that you are part of without informing the other person.

If you are in a two-party consent state, recording without consent could be illegal.


When Recording Is Typically Allowed

    Personal documentation

    Business or meeting notes

    Safety and protection purposes


When to Be Careful

    Recording conversations you are NOT part of

    Recording in private spaces where there is an expectation of privacy

    Crossing state lines with different laws
