Illinois is no longer on this list.
Thank you. I have updated my information.When must you get permission from everyone involved before recording?
Eleven 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, New Hampshire, Pennsylvania and Washington.
(1) Illinois' two-party consent statute was held unconstitutional in 2014;
(2) Hawai'i is in general a one-party state, but requires two-party consent if the recording device is installed in a private place;
(3) Massachusetts bans "secret" recordings rather than requiring explicit consent from all parties.
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.
