Recorded a conversation without consent

Was this a private conversation in a secluded place? Are you asking in terms of civil or criminal liability?

In NY is is legal to record a conversation as long as one of the people that is taking part in the conversation consents to the recording. If you are involved in the conversation, you obviously are consenting to the recording so it is permissible. Since illegal recording of conversations is a felony, you really should consult with an attorney regarding your specific situation before you decide to go forward with a recording.

One further caveat, if you are recording a phone conversation where one party is not in NY, you may be governed by the laws of another state so you really should consult with an attorney before recording any conversations.
