Joolyjoolyjoo; The amount of money the non resident parent pays is dependant on the number of children and is a percentage of the net pay.
I know many mothers who receive the grand total of £5 a week because ex's stop working and start doing cash in hand jobs to avoid paying maintenance.......
Ex tried to get out of paying CSA, they eventually caught up with him, in the meantime and after the fact, I still pay for the lions share of the up bringing of my children. IME this is the case for resident parents, the resident parent spends on childminders, and school activities and daily life, more than the absent parent ever will. I work my hours around my children, ex cancels on them when he feels like demands contact when he feels like.... it doesn't matter I'm always their for my girls, and he knows full well that should he disappear out of their lives there is always at least one person in the world willing to lay her life down for our children.
In the event I marry a multi-gazillionaire, I would still expect ex to pay child maintenance, they are now and always will be his children. They are not to be palmed off or ignored because our marriage did not work out. The marriage broke down, ex's repsonsibility to me is absolved, his children will always be his and all the repsonsibility that goes with it. Altho personally I'm just waiting for him to suddenly drop off the face of the earth in order to avoid paying maintenance.
Actually my point here is, that the resident parent gets CSA, that could be a mother paying for her chidlren, it's not sexist as far as I can tell.
Oh and whoever said it was a lifestyle choice to have children and live off of ex, if that had been my personal goal I'd have married a rich old guy on his last legs, far better odds!!!!!
