Consent of all parties is required to tape a conversation in Nevada. Intercepting or delaying a telephone conversation is a misdemeanor. Nev. Rev. Stat. Ann. § 707.900. However, if the interception is made with the prior consent of one of the parties to the communication and an emergency situation exists in which it is impractical to gain a court order before intercepting the communication, an exception may be made. § 200.620. This exception applies mostly to law enforcement officers who proceed without a warrant.

In addition, it is a crime to intrude upon the privacy of another by surreptitiously listening to, recording, or disclosing any conversation gained by means of electronic or mechanical device, unless authorized to do so by one of the parties of the conversation. Nev. Rev. Stat. Ann § 200.630, .650.

Violations of the statute can be punishable by $1,000 or $100 per day, whichever is greater, punitive damages for violations of privacy, and costs reasonably incurred in bringing the action to court. Nev. Rev. Stat. Ann § 200.690.
