Federal law permits recording telephone calls and in-person conversations with the consent of at least one of the parties. See 18 U.S.C. 2511(2)(d). This is called a “one-party consent” law. Under a one-party consent law, you can record a phone call or conversation so long as you are a party to the conversation. Furthermore, if you are not a party to the conversation, a “one-party consent” law will allow you to record the conversation or phone call so long as your source consents and has full knowledge that the communication will be recorded.
