My ex is champing at the bit to stop paying CMS for our eldest child who is going to uni in Sep and despite earning 6 figures is not providing them with any direct financial support 🤬. He has apparently worked out what the reduced payment will be for our younger children and already updated the DD accordingly (he pays me direct). This is due to go out on the 1st Sep. My question is whether this is correct as I thought CMS was paid in arrears? So does the next payment in fact cover August and if so, it would factor in our eldest as it has previously. Presumably then CMS will write to me with an adjusted payment schedule for the remainder of the qualifying year and payments are reduced from the Oct payment (covering Sep)?? Can anyone tell me which it is please - advance or arrears ? Feeling a bit stressed as I am a key worker on a low ish income and conscious that even though I will be supporting my eldest on my own I will obviously no longer be receiving child benefit and I think my UC top up will also be reduced as well as CMS so Sep-Oct are literally unknown quantities income wise. It makes my blood boil that a high earning biological parent is not legally required to provide any financial support to their student child but that's a whole other thread.
