They would probably have to see an independent psychologist and give the independent psychologist their "wishes" pursuant to the Family Law Act.

It is unlikely that any Court would make orders in respect to children of those ages, unless it was clear that one party had "alienated" them from the other - obviously not in your case, as it's his choice!

HTH.
The stat dec should go a long way to proving he removed himself - not the other way around.

Well that would be proof enough that he wants no part in their lives as well as the stat dec. Unfortunately the CSA has to by law persue any child support claim and mutual agreements are not enough these days.
Thats what I told him. At the time I was a non working single mum to 2 kids - I wasnt risking losing $200 a fortnight so he could skip out of $25 a month. But thats what he was asking me to do, knowing full well I'd lose most of my ftba.

Maybe stupid question, but if he wanted shared care, wouldn't that end up costing him alot more? I know what you get paid for support is not enough to raise a child, so to have to actually feed and clothe them himself for half the week would surely be more expensive.... wouldn't it?
Yeah - sadly its not about the money so much as the fact that he has to "give it to me".
