The Child Maintenance and Enforcement Commission is responsible for the child maintenance system. I have asked the Child Maintenance Commissioner to write to the hon. Member with the information requested and I have seen the response.Letter from Noel Shanahan:"In reply to your recent Parliamentary Question about the Child Support Agency, the Secretary of State promised a substantive reply from the Child Maintenance Commissioner as the Child Support Agency is now the responsibility of the Child Maintenance and Enforcement Commission.""You asked the Secretary of State for Work and Pensions, what proportion of Child Support Agency assessed cases with a positive liability involve (a) parents with care in receipt of income-related benefits, (b) non-resident parents in receipt of income-related benefits and (c) cases where both parents are in receipt of income-related benefits. [102728]""In the quarter ending May 2011, 18% of cases with a positive liability included a parent with care, who is in receipt of Income Support, Incapacity Benefits or Income Based Job Seekers Allowance.""11% of cases with a positive liability included a non-resident parent who is in receipt of Income Support, Incapacity Benefits or Income Based Job Seekers Allowance.""7% of cases with a positive liability included both a parent with care and non-resident parent who are in receipt of Income Support, Incapacity Benefits or Job Seekers Allowance."
