Hi Wonka, Yes, that would be the next step in a normal world. Except, XH is self-employed... and so there is no wage. And there are no tax returns, and he has no assets in his name.
He really has all bases covered.
One thing our agency does here is to prevent overseas travel by those who have significant outstanding child support payments.
So eventually, if he chooses not to pay, he will be turned back at the departure gate on one of his luxury overseas holidays ...
