To qualify for maintenance payments a child must meet the Child Maintenance Service's criteria. They must be:

  • under 20 years of age and
  • in full time non-advanced education or approved training, and
  • eligible for Child Benefit.

They must also be habitually resident in the UK and usually living in the same household as the receiving parent. Child maintenance defines a child the same way as Child Benefit does to offer consistency across rules. Child benefit is not used as a blunt tool in determining who may be considered a receiving parent and the CMS can consider multiple different forms of evidence when determining who is the primary carer.

If a paying parent believes that the Child Maintenance (CM) liability should cease because a qualifying child (QC) no longer meets the statutory definition of a qualifying young person but checks with His Majesty's Revenue and Customs (HMRC) disagree, the CM caseworker can ask the receiving parent to provide;

1. verbal confirmation of the QCs status if they agree that the paying parent’s statement is correct, or

2. where they disagree with the paying parent, a letter from the school or college confirming the QCs status, or

3. written confirmation from an employer that the QC has started work.

Where the paying parent believes that Child Benefit is claimed fraudulently, the paying parent will be signposted to report the fraud to HMRC at Gov.UK.

Child Maintenance Service make automated monthly requests to HMRC asking for all children aged 16 to 19 who are included in its caseload, to establish whether Child Benefit is still in payment.

The CMS has a Financial Investigations Unit (FIU), that can investigate complex cases. This is a specialist team which can investigate the accuracy of information the CMS is given by either parent.
