No. Frequently, divorce litigants get discouraged because their soon-to-be ex alleges blatant lies in pleadings to the Court. Quite often, clients desire the self-help remedy of recording conversations, either on the phone or in person, to disprove these false allegations.
Unfortunately, Nevada is considered a two party consent state. This means that both parties must consent to calls/conversations being recorded. Under NRS 200.650, it is a Class D felony (!) for a person to record any private conversation without the consent of the other. The statute provides for possible imprisonment and monetary sanctions. Bottom line: you don’t want to do this.
Having said this, some judges will authorize divorce litigants to record calls if the communications seem to get out of hand. This is more of an extreme remedy, and you can’t use it to justify recordings made prior to the judge’s order.
