Pennsylvania recording law stipulates that it is a two-party consent state. In Pennsylvania, it is a criminal offense to use any device to record communications, whether they’re wire, oral or electronic, without the consent of everyone taking part in the conversation. This means that in Pennsylvania you are not legally allowed to record a conversation you are taking part in unless all parties are in agreement. 18 Pa. Cons. Stat. Ann. § 5704 (West 2012).
