sounds familiar mate... Been there done that.
The advice I got. you can spend a small fortune fighting it... You might win, you might not... But you can accept without admission for free and save your $$$ for family law. So if there are kids involved? get back to me. That is a game changer.
Sounds like there is? so give more details - how long since separation?
I'm familiar with nsw - But Vic is probably not that different.
Final AVO
Go down to the bit about the "applicant being successful".... So there is no "beyond reasonable doubt" here. It is on the grounds of probability... Toss a coin, probably heads / possibly tails. MADNESS..
WORSE it isn't whether or not it is probable that you were violent... That would at least give some chance of getting a reasonable hearing. BUT it is whether or not it is probable that she fears you...
So with a hole in the wall, she is well on her way... Now the fact that the cops have done it on her behalf, suggests to me that you're stuffed.... See if they thought it was frivilous they could refuse to do the application. They have accepted her statement and hence served you (again, that is how NSW works, not familiar with Vic - but confident it would not be too different)
So my advice consent without admission, save your $$$ for the real fight - getting to see your kids... BUT get back to us here with a bit more detail and you'll get good opinions.
