XP currently pays £37 a week and has done for for 12 years. Now DC is older it’s obviously a lot more expensive, I earn but nothing amazing
XP has own home, is married and has 2 other DC’s, my DC doesn’t stay there at all, visits but doesn’t stay
AIBU to go via CMS and ask for more? I don’t know he’s earnings but owning a house and going on holidays I’m guessing he’s not too badly off
YABU just leave it as it is
YANBU it’s fair to ask for more
