Under Kansas law, unlawful eavesdropping consists of secretly listening to, recording, or amplifying private conversations or using any device to intercept a telephone or wire communication “without the consent of the person in possession or control of the facilities for such wire communication.” Kan. Stat. Ann. § 21-4001.

Violations are misdemeanors. A criminal breach of privacy, punishable as a misdemeanor as well, occurs when any means of private communication is intercepted without the consent of the sender or receiver. Divulging the existence or contents of any type of private communication, whether carried out by telephone or even letter, is also a misdemeanor if the person knows the message was intercepted illegally. Kan. Stat. Ann. § 21-4002.
