What REAL, meaningful support is there out there for such a person?
I can tell you from experience in a very similar situation that practically speaking, there is no real, meaningful support for such a perswon. The whole system is completely an utterly genderised so that women get pretty much all the support they want, and men are treated as perpetrators by definition. When my journey began, I naively thought that "If you haven't done anything wrong, the truth will set you free". I didn't have enough money to fight the DVO in the magistrate's court AND pursue a family law case, so I essentially relied on duty lawyers to advise me how to handle the DVO. I thought I had nothing to lose in trying to oppose it.
Over time, I realised that whether you're guilty or you're innocent, you're bent over just the same and treated as though you are guilty in ways that are arguably worse than in criminal law where you at least have the presumption of innocence and the prosecution needs to PROVE you committed the crime. Not so with a DVO. A plausible claim and no evidence is all the applicant needs.
It took 13 months to get to a contested hearing, longer than it would have taken if I had consented without admission in the first place. That's 13 months without justice, without being able to tell your side of the story. 13 months being forced out of your home and deprived of almost all your belongings, and sometimes deprived of contact with your children (if I didn't have the sense to pursue access to my children through family law, that may well have been the case).
On the day of my contested hearing, after having been told by my family law lawyer that there was nothing to gain and everything to lose by 'winning' my IVO case, I decided to consent without admission. The police officer that was prosecuting my ex's case, only once I had consented, admitted that my ex's case was very weak, that she had admitted to hitting me and the worst she had accused me of was pushing her away, and that normally that isn't what IVOs are supposed to be for. They warned me to be careful around her because she was clearly gunning for me.
So sure, Tim and Allison may have their many years of personal experience, but I suggest there may be some confirmation bias going on. Every case should be heard on its merits without prejudice. There is a huge amount of room for abuse in the system. I don't have the statistics on how often such cases are vexatious (and I suspect nobody does, given how most end with consent without admission and no testing of the facts) but I know how beneficial they are to people in parenting matters because they effectively make you primary carer by default, and once you're primary carer, that's likely the way it will remain for the foreseeable future. Apparently around half of all cases being heard in the Family Court involve a DVO these days.
