If the non resident parent has a 'relevant other child' living with them that they or their partner receive chb for, their income pool is reduced by 15%.
for the sake of the argument, XP had an affair and left. At the time that we had our three children, we were both working in relatively low paid, but stable employment. He then left OW when their DC was 9 months old for OW2' lost his job, had a variety of mental health issues and was unemployed for 7 years until OW2 conceived a late unplanned baby.
For the sake of the argument, if XP had been working earning, say £2000pcm, for his first subsequent child, his salary would have a 15% ringfence, so £300 for subsequent child leaving £1700 in the pot. My children would have been entitled to 25% of that pot, so £375, £125 per child. Both parents were working and contributing to household finance. I maintained a house on my own with three children
Moving on, he left OW for OW2 and had another (unplanned) child. The fictious pot of £2000 would still have a £300 ringfence for 'relevant other child' 2, but the 25% remaining in the child maintenace calculation would now stretch to my DCs and 'relevant other child2' (i do apologise for the terminology, it isnt mine) so £375 split 4 ways = just under £90 per child.
When couples have children they hopefully discuss the finances. When relationships end, for whatever reason, the discussion regarding finances for subsequent babies with new DWs doesnt really reach the parent with care. These are not our choices. We suck it up. The child maintenance system does need serious overhaul. Not just for collection (is it around 25% of parents with care that receive nothing? Is it higher?)
With regard to unplanned children, all of mine were planned, not that i can actually see, even as a tax payer that that is any of your business. Without foresight, i could not see that the man i loved would leave me and create a Jeremy Kyle-esque nightmare in his wake. I am lucky that I have always managed to work, but I could feasibly lose my job tomorrow, we all could, even higher rate taxpayers. I could have an accident or develop a tumor or any number of circumstance that would determine that i would have to claim state benefits.
Which of my children do you think i should give to a nice middle class married working couple
