Pistachio,
I am struggling to understand this a little.
How long were you married for? For how much of it was it a working, living together, marriage?
If it was a long marriage (over 10 years) the starting point is 50/50 on assets, and you can get more if your ex is a high earner. The general principle is putting both parties in a similar position in terms of spending as when they were married. Exceptions are pre marital assets, but these only really make a difference in large settlements (I. E when the lifestyle can be maintained and there are ‘left over’ assets).
Self employed people can lie more easily but any court can see that private school fees, expensive German pieces of metal and houses worth nearly 1mil are not bought on an income of £40k and/or decent assets.
Where are you with the divorce? You do need to jump through the hoops, but so does he. Lying on a form E (statement of income and assets) is a criminal offence.
I am not a solicitor but there are loads on these boards, not a forensic accountant (these are rarer but I bet MN still has a couple).
I would say, however, that ‘moving on’ (practically, as opposed to emotionally) comes after finalising the financial settlement. Your best hope for a decent lifestyle for you and your daughter is investing time and energy in the divorce.
Questions I would be asking my lawyer in your shoes are:
1/ Can we agree interim financial support during divorce process. If not, why not.
2/ Can we request a form E as soon as possible and get a court order if necessary.
3/ How would your lawyer recommend getting a true picture of your ex’s finances?
You could probably help with the latter a lot if you know what he owns. He can claim debts against them but he would have to evidence them.
You can get help financing legal bills if the prospective settlement is reasonably large. There are shark type loan companies (not really recommended) but also family, friends etc. I don’t know if any lawyers would accept pay out of settlement or to take a percentage. Another question to ask.
I would speak to a couple of high powered lawyers (some do offer a free telephone chat, though not small) and see what they advise.
