My DD just got one. He didn't turn up for Court.
There had been physical stuff, but that is still to be heard in Court, because via the local DV Services, the Police are now pursuing criminal charges. Before that they hadn't followed procedure and had just ignored my DD reporting it.
So the non mol is based on threatening texts and phone calls. These included threats to kidnap their children.
It's made him take things seriously.
It took two Court hearings, my DD got legal aid.
Her ex wouldn't answer his phone etc, so he couldn't be served. The Police helped out by calling him into the station.
The male server told my DD that he wouldn't give up, he hates the perpetrators of DV. He followed him from the Police Station. Not exactly protocol, but until they are served, they can't be arrested for breaking the conditions.
They can still be arrested for their behaviour, of course.
