Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, in how many cases child maintenance was not collectable as a result of a Child Maintenance Service administrative error when a deduction from earnings request was made to the armed forces in each quarter of the last three years.

The Child Maintenance Service does not record this data as there is no facility on the Child Maintenance System to record instances when a Deduction from Earning Request has been rejected by MoD or where an administrative error occurred.

As the information requested is not collated centrally it would require examination of individual cases and could only be provided at disproportionate cost.
