What would you do if your soon to be ex husband?

had been made redundant in February and that was the last payment from the CSA, but since then has been making money by doing courier work with you having no idea of how much is being earnt and has not given you a penny. He willl not go on job seekers allowance because he is doing cash in hand work, the law states that if you are on job seekers allowance you are entitled to �5.00 week. By the way, I was perfectly happy with a verbal agreement but had to go to the CSA in the first place as nothing again was paid for four months after the break up.
