Sorry I seem to have started quite a debate.
Just to clarify AGAIN - this has never been about which figure DH should pay, I just wanted to know whether the calculation was correct as I never for a minute thought that they would calculate the figure based on his net net pay, after the childcare vouchers have come off, after all, they are income.
I have stated all along that I think it would be unfair to reduce the amount as DH's income hasn't really decreased, but if he decides to pay the lower amount then that is up to HIM. I am shocked that the CSA have actually calculated it this way, because it doesn't seem right or fair for the amount to be reduced because of DH's company benefits.
I have also stated several times that I doubt very much that DH will decrease his payments as he just wants a quiet/easy life and it really wouldn't be worth risking an argument or risking his ex reducing contact over the sake of about £10pw.
He is not the one who asked for a reassessment, he was happy paying the original amount, we're not wealthy people but we can afford it so there's no reason for him to reduce his payments, especially not just for the sake of 'getting one over on her' as some people have suggested. This isn't his attitude. He is the most laid back, easy going person, that really isn't his style.
I only mentioned his ex's pay in reply to somebody asking if the children would go without if he was to pay the lesser amount.
The answer being - no she is on good money and their (her and her partner's) household income is much greater than ours.
This does not mean that DH should not pay a fair amount (he does, always has done and always will pay what he should) but I was just making the point that she is not a poor struggling single mum who relies on DH's money to put a roof over their heads.
And in reply to those insinuating that I am some bitter new wife who doesn't have a clue - I also have an 11 year old who I brought up on my own for a number of years before meeting DH. So I do know what it is like to be a single parent.
I am not ''living off my husband'' - I am temporarily working part time until our child starts school, because that is how we decided that we want our child to be raised. And even if I did work full time it would make little difference to our income due to childcare costs, so would I still be ''living off my husband'' if I worked full time but paid out most of my wage on childcare?
I don't like the woman for very justified reasons (reasons which I won't go in to) but that is pretty irrelevant. Whether I like the woman has got nothing to do with the amount of money DH will pay for his DC's.
DH is a decent bloke who works hard to provide everything he can for ALL his children, they all get everything they need.
