But I just can't work out why the csa is saying £72pw?
He won't stop paying - it's too delicate. She truly believes that while dss is never there, he does actually still live with her (she has a court order that says so, innit?). Despite the fact that even she doesn't live with her - she appears to have moved out of the the house she bought jointly with a bf, using her spousal maints, and moved in with another bloke - as a result she says dss can't stay there. And that she wants more money.
If he stopped she would kick up a huge fuss - she would tell dss he had stopped and that he had to go and stay in the other house with the SD he hates (and who he called social services about - sigh) even though she isn't there herself, and she would go to court for the money and claim black was white to get it back.
I think he should halve it - that way she is far less likely to want to bring a court case and she might see some sense in dss staying here.
Having said that - I am sick to my back teeth of him now. 15 yo are tricky enough, but more so when they are not your own and when their mum has no interest in them and when their dad lets them get away with murder.
Dp was going to talk to her about paying him more attention if nothing else - she told him not to tell us she'd moved in with a new bf, we're not even supposed to know about the bf, and he had to lie to us about where he had been staying, so dp was going to meet with her and bring that up, but it was weeks ago and he's done nothing.
We're not short of money so it isn't an issue that dss is suffering because of it (unless you count not having an iphone 6 as suffering, which he does!) - but it would be nice to, I dunno, have new sofas as ours are her old ones which she replaced before they even split up and has replaced the replacements since plus bought another set as their new house had two sitting rooms! (I don't do credit, which is why we've not had new sofas, she does, which is why she has had three sets of new sofas in seven years and why she is always claiming penury).
We already save for him but it's a good point that dp could save more. I bet she isn't saving for him - in fact, I know she's not, she took the £7k out of the savings his granddad had made for him and has never replaced it let alone added to it (dss can see the account balance).
I may be reaching the end of my tether I now realise....
