You can record somebody without their knowledge. But if you're trying to admit it into a court case as discovery, the judge will rule on the admissibility of the recording. I have recorded family members, friends, etc.I record as for my protection and a receipt of what just signed in on. When aguaintences tell lies, the story doesn't comeback tol anybodym
I am pretty sure it is illegal. I know someone who got arrested for it during a ugly divorce. Courts alow texts, and voice mail recordings, come in as evidence in cases, but they do not submit or allow unauthorized recordings in as evidence to my knowledge. I believe Its because statements are being made by individuals without consent.
