My minor child spoke with his father by phone for a court-ordered call and thought he hung up the line afterward- but he did not. The phone line was left open, my ex-husband didn't hang up and eavesdropped into our home for a long time. Now he is "reporting" what he claims he heard over the line to try and change custody. Is it illegal that he eavesdropped and did not hang up the phone? The eavesdropping went well beyond the phone call time allowed by the court order and phone records prove the length of time he listened. He is reporting a manufactured version of lies of what he claims he heard to authorities when I did nothing wrong. In court would his "story" be hearsay? Can I file criminal charges for eavesdropping or do I have to have evidence of a recording to take any action?
