Child maintenance

Ronnib

Hello looking for some advice please.
i am the third respondent on a child maintenance appeal.
i have found out today that the appeal has been allowed. I am trying to get some advice on what happens next.
The apeallant appealed on the basis that she thought that the paying parent (1st respondent) was underpaying her.
 I received monthly payments from the paying parent for my two children.
appellant received monthly payments from the paying parent for her one child.
appellant thought that the money should have been split two ways not between tree children as she believe that my eldest child should not be considered as she was not in full time education.
I at all times have maintained that she was in full time education, the college provided documents for council tax exemption for child benefit and this was used as evidence.
this case has rumbled on for over four years now - my payments for both children stopped over four years ago. However, further evidence has been provided from the college showing that her actual supervised hours where on average 11 hours a week, less than the minimum of 12 hours. The college still claimed for her as a full time student but the court has now allowed the appeal based on her actual hours.
How. when will I be expected to pay within back and how will it be calculated. Clearly I am extremely anxious as to date I have always been under the impression that she was classed as a full time student.

As an add on the amount the paying parent paid was set by CMS but was paid monthly not by standing order of as direct payment

Have you been officially notified by CMS about the change in the payments you will receive, and does it say you will need to repay?
