That's what I said: They do underestimate. It doesn't show up as often as it ought to in the pleadings, so I agree absolutely that it's underestimated in the pleadings.
What we were looking at were cases where custody and access were to be determined, so violence may be relevant to property issues but not particularly. Where violence is very relevant is in terms of custody and access determinations. The arrangements that are made for the children can make it possible for the perpetrator to continue the abuse post-separation.
