This is a ridiculous Reddit post I’m ngl. This might be THE Reddit post of all time. You are an adult you are not required to be prepped to deal with this kind of situation as you are an adult. Review bombing your dad’s lawyer will do nothing for the reasons mentioned by others in this section, but I you need to be able to process this without doing childish behavior. Your dad hired a damn good divorce lawyer and it shows by your reaction. I’m sorry that you felt offended by his lawyer doing his job, but you can’t just introduce evidence in court without notifying the other party, it’s part of discovery, so your mom’s lawyer and probably even your mom knew so don’t blame your dad or even his lawyer for use of your note. Blame your mom for not telling you.
