Just that really - STBXH thinks that paying the CMS minimum (8% of his gross salary) is sufficient financial responsibility for our son, and that he needn't pay more. I disagree.
To illustrate:
If I paid only 8% of my income it would amount to £169 a month. That in addition to 8% of his income (£466 a month), totals £635 a month. An amount that doesn’t even cover my son's nursery fees.
So by his logic, after paying his nursery fees, I therefore have no further financial responsibility for my son as I’ve paid the amount deemed sufficient by the CMS.
Obviously, I don't just arbitrarily assign 8% of my income to my son, and instead pay for what he needs.
AIBU?
