There is zero reason to have contested divorce. There is nothing to contest here. Even if you can prove abuse, what is being contested with no property, no assets, no kids, no money and a marriage was very short lived? That’s the only thing that people contest: custody, property and assets. I am not really understanding why contested divorce was being brought up at all. Maybe there is something I am missing. I’d not stress myself about it and would just go for typical no fault divorce.

Plus it’s extremely hard to prove abuse in absence of collected evidence. He is an ***** but that might not be enough for a proof

I suspect the fact of police being called might not be enough and he has recordings now that might play against you.

Honestly I’d just try to go for getting it over with so you can move on.
