Do you have to inform a person that a conversation is to be recorded?

Yes, in many jurisdictions, it is legally required to inform a person that a conversation is being recorded, especially if the recording occurs in private settings. This is often governed by wiretapping laws, which can vary significantly by location. In some places, only one party needs to consent to the recording, while in others, all parties must be informed and agree. It's always best to check local laws to ensure compliance.
