I will admit, MJ, that I agree with you on that point - The DWP don't recognise shared care agreements. They should. But then, if my Ex-H was able to claim x% of the TC's I get at the moment for DS1 (Different dad to DS2&3) - I'd still be paying for ALL of DS1's clothes, school trips, shoes, after-school clubs AND school swimming lessons, as I am at the moment - just becaus ehe got some of the TC's, doesn't mean his new partner would 'let' him spend it on DS1. I would have to pay ALL the costs out of less than all the TC's.
I USED to give DS1's dad the TC's for DS1 for every day he was there, and before Ex-H got with his new partner, he paid half for all the costs mentioned. As soon as he got with new partner - that stopped. Until Ex-H is willing to pay half the additional costs for DS1, I'M not willing to give Ex-H any of the TC's. So Ex-H's new partner shot herself in the foot there, as I was giving them the money. Also if they stopped keeping clothes that I paid for, and want to hand down to MY DS2, and giving them to Ex-H's new partner's son when I'VE paid for them, I would be more likely to split the tc's again.
So, the problem is, the DWP's computer systems aren't set up to recognise shared care, AND the DWP are worried about making some PWC harder up if their ex-partner refuses to spend the split tc's on essentials like clothing, which the PWC would still have to pay for. I can see both sides of that one!
