Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many cases on the Child Maintenance Service system have child maintenance arrears, due to be paid by the non-resident parent, which were incurred under the 1993 or 2003 child maintenance schemes.

Information on the number of cases with transitioned arrears from the 1993 or 2003 schemes is not readily available and could only be provided at disproportionate cost.
