@iovemilton you have my internet hugs. Whether you want them or not 
My experience of family law in the UK is 16 years ago. My experience with Irish family law is ongoing.
@smeddum is correct with saying that it is up to the judge whether or not they wish to see said text/recording.
Family court is already full and they dont care unless the solicitor is able to present this as new and relevant information. Even then, they exercise their own discretion. Quite frankly they are too bloody busy.
Family law court is a shit place to be.
An access order is a civil order which carries potentially criminal consequences. If you breach it, the other party can call the Gards who will note it and tell you to take it back through the civil court.
My order says that The Idiot has access on dates/times X, Y and Z. I must therefore make the children available for access at this point. If a reasonable time elapses and he hasnt turned up, then I can refuse the entire access period. I could go on for ages about this, but wont.
Once you are in the court system you can't really get out. If you act outside the court order, you are technically breaching it- even if you are both in agreement. If you want something altered it has to be put before the court (be it a mutual agreement or a hearing) and have it signed by a judge. Court Orders dont disappear.
My heart truly does go out to OP because once you're on that hamster wheel, minds have been made up.
Judges do not like to go against each other.
My ex-idiot has a nutbag girlfriend who is a flaming nutjob. The things she says and does... there's nothing I can do. This is on advice from solicitors, family law lecturers and doctors. Emotional abuse is the hardest to prove as it takes time to build. In the meantime, I dont stop them hating her and let them call her 'the Emmaroid'.
There is nothing I can do at this point. I truly feel for OP.
