When child maintainence figures are calculated, and the non-resident parent who will be making the payments has married again (but with no children arising from that union!), is the new spouse's income taken into account because, surely, it has become the non-resident parents joint income through marriage. Confused? Well - my ex-husband(very well off and highly paid pilot) has calculated that he has to pay me 25% of his net income BUT that his new wife's equally hefty monthly income is absolutely nothing to do with our children, despite the fact that their wages are paid into a joint account and he, therefore, has full access to that extra money each month. Surely, this then becomes a part of his net monthly income? I am so confused and the advice from the CSA has been about as helpful as a chocolate fireguard. Can anyone help?
