I wish people would read the thread, or at least the OPs posts before they start frothing about benefits
the OP gets DLA for a disabled child.
DLA, like PIP, is not means tested - its to help with the extra costs over and above normal, which having a disability entails.
That said, the DLA and CM for eldest should be taken out of the equation, because effectively these are not monies that should be available to the OPs partner.
I think I asked earlier, but given the extra info about CM
How does your partner feel that he is being subsidised by a disabled child - does he think thats OK?
And how would your ex feel, knowing that this sponger is having reduced costs because of his CM payments?
remove CM and DLA from your income amount.
what is the difference between your salaries now? if you want to be fair you can do it proportionally.
Does that make his £500 more or less reasonable, especially given you have a £600 childcare bill, which no doubt allows him to work too?
and yes, he should be paying for their clothes and activities. AND doing half the chores as you both work full time.
for comparison, my daughter who is disabled, who gets PIP/UC and is currently at uni so gets a grant, pays me £450 a month, food, rent and bills included. her income is less than your partners. She doesnt have any children to be responsible for. Your partner is taking the piss, and he SHOULD be paying a fair amount, not griping about his freeloading. Its called respect.
