[quote Sillysandy]@Blendiful yes if he planned to backpay I would feel differently. I guess this situation could be more nuanced than it looks with one perspective
But based on what I have read he really does seem to be operating as if his responsibilities toward his eldest children are optional. He didn't come to an agreement with op, he told her what himself and his wife had decided.[/quote]
He probably should have discussed with OP but ultimately if she had turned round and said, no I need that £250, should he have not agreed to give up work? Even if that meant his other 2 DC would lose their home and bills would go unpaid?
I highly doubt he has decided to be a SAHP based on wanting to stay home all day and not pay a penny. Most people who have been in work want to continue to work; if they can, even part time. He paid £250 before it seems and when together agreed to be the main breadwinner so OP could be a SAHP, why would he choose now to decide to not bother paying for anything unless it wasn’t financially viable to?
Most of the time the reason any parent becomes a SAHP is because it makes financial sense to do so due to high childcare costs. Sometimes because the parent wants to stay home with the child also. But given they have twins and their costs are 2x I am making an assumption that it is likely to be for financial reasons.
If his wife earns more and either way they are going to have to go from being a 2 income household with 25% of SC to a 1 income household with 2 100% children and 2 25% SC then surely she needs to be the one to work. To literally survive and pay the bills.
If the calculation was done on CMS and he was paying £250 it seems like he probably earns around 25k a year, that’s not a lot to pay for 1 household of 2 adults and 2 children 75% and 4 children 25% and another 25% of the other DC care especially if living costs are high. It’s £1720 a month, take off maintanence leaves £1500 to cover all of the above plus including babies needs which include nappies/milk etc as their DC are still young. If his wife earns more and that meets their living costs then that’s what they have to do. I think a lot of families of that size would struggle on that income to cover all costs.
