Yep i would report it to them My ex is the same he works in the mines and knows how to hide a lot of his income he also owens a home but put it in his mothers name so it doesnt show as his asset i reported it to them......he got busted big time!!! He would pay the morgage on it in weekly payments to his mum via net bank and they traced it at. If you have any thing to back up what he is doing or any info that can help them i would call them and ask.Why not.

My ex see's it the same as well that he earns it why should i get so much it dont take all that to raise a child......but thats not how they base it they base it on if he were here what would he be spending on the child(also with account of course of what it does coast).

As for getting rewiews clover she can request a review if she has a good reason like change or circumstance ect
