Rickman - I've just seen this!
What a horrible piece of work he is, but you knew that already didn't you! Just showing his real colours now!
I think if these accounts have been submitted to the CSA you will need to find some way of challenging them. Is he self employed as a sole trader or does he have a company? If it is the latter I can get a set of accounts from company's house and have a look at them for you! If the former - there isn't really any way to get them!
You really need to get a solicitor on the case as the judge can ask for complete financial disclosure as part of the settlement. This settlement goes beyond the CSA and looks at teh split of all matrimonial assets and the provision of maintenance for hte children and you! Freckle will know more about this than me.
The financial disclosure to the Courts will give details of all assets owned by him and you. So teh cars, house, bank accounts etc are all caught. The judges are pretty good at looking beyond the self-employed accounts to get some idea of actual income (by asking for business bank accounts) and if the cash flow shows a different answer from the accounts themselves then they have to explain why. A pretty dim view is taken of non-disclosure. As party to all this you can instruct your solicitor to ask why things you know exist haven't been disclosed so at the end of the process the position tends to be more complete!
I know you didn;t want to go to court for a financial settlement, but to be honest I now don't think you have much choice! I think you stand to get a fairly good settlement going down this route, particularly because he retained the matrimonial home. It is tempting to say sod it and walk away, but the financial security of your family depends on you fighting this one out!
So be brave girl - get Freckle's advice - get angry and get moving
