Bit of background ... exP and I split up when DS was sixth months' old; reasonably amicable, but things have become more complex now due to money. We both work; currently we split DS's nursery payments (£1100pm) on a salary-ratio, and exP pays me £120 a month on top of that.
However, I've been living rent-free for a year and am about to move into rented accommodation (which will cost over two-and-a-half times what exP pays for his place). My feeling is that his maintenance payments should reflect that (we both earn decent money, but live in central London). According to the CSA calculator he should pay me around £400 a month, but he thinks this ought to include nursery fees, and I think nursery fees should be worked out separately, and that the £400 is maintenance. Can anyone tell me who's right? £400 wouldn't even cover half of DS's nursery fees, never mind anything else, so I'm pretty much hoping it's me!
