Who must give permission to record a telephone or in-person conversation?
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.
In addition to federal law, thirty-eight states and the District of Columbia have adopted "one-party consent" laws and permit individuals to record phone calls and conversations to which they are a party or when one party to the communication consents. See the
State Law: Recording section of this legal guide for information on state wiretapping laws.
When must you get permission from everyone involved before recording?
Twelve states require the consent of every party to a phone call or conversation in order to make the recording lawful. These "two-party consent" laws have been adopted in California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania and Washington (Hawai'i is also in general a one-party state, but requires two-party consent if the recording device is installed in a private place). Although they are referred to as "two-party consent" laws, consent must be obtained from every party to a phone call or conversation if it involves more than two people. In some of these states, it might be enough if all parties to the call or conversation know that you are recording and proceed with the communication anyway, even if they do not voice explicit consent.
