Family courts are a blunt tool used because there is no better alternative at the moment.
Take your typical warring couple. Most of the time they are throwing accusation and counter-accusation at each other. They cannot resolve the situation at mediation hence court. By this time both are so entrenched and convinced THEY are in the right that it really doesn't matter what the court decides. Unless it is the absolute vindication of one against the other, both will leave disappointed.
To give a hypothetical example, Mum left abusive relationship. Uses that as her reason for witholding contact. Says he's abusive, besides which he's not paying maintenance and this place is totally unsuitable for their daughter.
The ex wants half the week since he's dad and doesn't see why he should pay maintenance when she's not letting him see their daughter anyway.
There is a big gap here and it's all too common. Courts have to unpick the lies from the exaggerated and extrapolate the truth somehow then decide what they think is best FOR THE CHILD, not the parents.
Court eventually decides something like I don't know...alternate weekends. Dad leaves pissed off because he's only seeing his daughter once a fortnight. Mum leaves pissed off because court has decided to allow contact to (in her opinion) and abusive man.
Both leave feeling family court has let them down.
But as a neutral third party the court (and even ourselves) may think the result is fair.
My point is that we're using a court system to decide on issues surrounded with emotion and the law isn't really suited to deciding on emotional issues.
