Child Maintenance and Other Payments Bill

Let us consider a situation in which a self-employed individual is declaring an income of £10,000, which is considerably less than they are probably earning, and they then realise a capital asset of £1 million but that cannot be included in the settlement. That asset has a notional income—if it is invested in the stock market or in a high-yielding savings account—of about £50,000 a year. Is there any way of taking such income into consideration when coming up with settlements?
