I am livid, my EXH went 'self employed' in 2012, since then I've received £52pw from him. After two years I asked the CSA to reassess him, they wrote to me telling me I should now get £140pw...brilliant I thought, until I got a new letter only 3 weeks later stating it's now £21pw.
It turns out he didn't provide the information the first time, so they used their calculator to take a 'stab' at what he 'might' earn and based the £140pw calculation on that!! He's then sent in his books, which are very well cooked, and now I'm only entitled to £18pw.
The CSA are useless and really do not want me to dispute this or ask for a mandatory consideration. I'm disgusted he's a self employed IT contractor who's sneakily claiming he only earns £145pw......
I don't seem to have a leg to stand on :(
