Csa for two children with seperate mothers

Steadyedy

Right so I have two amazing daughters from seperate mothers. Child one when the mother and I split she owed money from the house so we agreed to deduct money weekly for my daughter for last 4 years until it's paid off. That is now paid and she has made a csa claim which I am fine about. But.....
She is adamant that my daughters because of seperate mothers are dealt as seperate claims.. Ie 15% of my wages for each child. I was under the impression it was 20% for two children and then split so 10% to each parent? My other daughter I have an amicable agreement which calculates to the 10% I mentioned. I am all for paying for my children but an extra 10% will leave me struggling to get by as I live alone. Can anyone shed any light on this please? I'm Yer to receive contact from csa yet but I'm worried they will just start taking what they want..

System

From http://www.childsupportlaws.co.uk/how-much-will-i-have-pay.html

What if a parent has other children?

If a resident parent has children with several different non-resident parents, the CSA will make these calculations separately. For example, if a woman has two children by one father and one by another man, the men will only pay for their own children respectively. Similarly, if a non-resident parent is paying money to several children in different households, the CSA will generally divide the money equally between the children.

My bold

In other words, its 20% split between the 2 PWCs. However be aware of:-

If the non-resident parent has some CSA arrangements and some Family-Arrangement maintenance then unfortunately, the CSA cannot take into account the Family-Arrangement maintenance paid. It can, however, take into account any court orders in relation to maintenance.

I thought this to be the case... She's been crafty sugguesting I keep an agrrement with my other childs mother.. So really im better to just out both directly through the csa? Other wise unless on their system they will be charged 15% for my one daughter. Really apreciate comments! I've been so stressed the last few days!!

The above post was true for the CSA but isn't the case for CMS. CMS will take account of your family based arrangement in the same way as if it were another case, so long as they can verify the arrangement exists.
