Edam, Interesting to hear your views so please continue to contribute. The point being made is that responsible and involved NRPs have housing costs for children so this is a neutral item for each parent.
In addition a lot of NRPs handed most of the previous house equity so the PWC has had housing taken into account. Also most PWC's get CB - which never seems to be mentioned in calculations.
Everyone's circumstances are different so I think CM should be based on actual costs.Parents should work out what a child costs, clothes, food per week, school dinners, activities, school trips etc and then they should split the costs equally. This way both parents are forced to contribute and the costs are known.
I would be interested to hear from PWCs (I am one) if they think this would work. I wouldn't have an issue sharing these costs - why would I?
Travis, I don't think your DH has to justify his position on work. My DH was told by his ex that 'she wouldn't allow him' to downsize from a highly stressful job to a profession like teaching as it would mean less money for her. Honest you can't make this stuff up and men have the bad press for being controlling!!
I would however advise him to give the ex notice - everyone needs some advance warning of changes in money. I would also recommend that he works out what the actual costs of raising his child are school dinners, school uniforms etc and makes sure there is room in your budget for these. If that means he has to earn some money then so he will have too.
So in summary - yes children should be paid for by both parents but let's base it on actual costs rather than a %.
Btw, CSA amounts = 15% of income isn't a small amount, if it was, no one would complaint about tax rates. I wish I could contribute 15% of income to raising my child, I don't think any parent normally does this so the CSA amount is generous.
Also most NRPs pay - yes there is a % who don't but even on the CSA own stats most parents so it's wrong to assume all NRPs are feckless.
