Hi there, Last year my Mum passed away and since then there has been a lot of arguments, contentious issues and general lack of communication between my siblings as we work through the estate division. One sibling is hyper-paranoid and very disagreeable and has made threats to use audio clips she made from voice recording phone conversations (without us knowing) to use them against the other siblings as leverage. While there is nothing that I am overly concerned about, there were times when she would call and be quite strange on the phone and ask very probing questions that were framed to get a specific answer regarding possessions and also information about other people who are involved in the estate division. My questions are: what can be done with these recordings in a legal capacity? Is it illegal to record people without them knowing? She has threatened to share the recordings with other family members - I know there is nothing I can do about this - but should she want to use them in court etc, can they be used? Thank you in advance.
