So me and ex have a DS (2 years)
we are no longer together and things have gotten quite nasty, him and his gf threatening court, to take my son and never let me see him etc etc
Recently ex came to pick my DS up for his weekend with him and I realised later that whilst getting his stuff he had dropped his phone and left it behind.
the phone was unlocked, so I had a look and found various messages of 'tactics' he would try to make me look bad / things to try and use against me in court. Very underhand stuff.
I took photos of these messages.
I also gave the phone back when DS got dropped home. I didn't mention I had looked at the phone.
I understand that what I've done may be unethical, but is it illegal? If it were to go to court could I use these messages to prove ex has been trying to set me up etc?
