Child Maintenance Service Withdraws Tens of Thousands in Erroneous Deductions

Context The Child Maintenance Service (CMS), created in 2012 to replace the Child Support Agency, collects payments for children whose parents live apart. It can deduct money directly from wages, bank accounts, benefits or pensions when parents fall behind. Recent cases reveal that the agency is still pulling funds based on outdated or incorrect arrears, sometimes decades after the original support order ended.

Key Facts In December 2020 the CMS withdrew £19,269 from the bank account of John Hammond, a maths teacher in Peterborough. Hammond, who had not owed child support for more than ten years, discovered the deduction while checking his first‑month salary. He described the shock as “so intense I couldn’t stop shaking.” After a year of appeals, a county court ordered the full sum returned and awarded him £8,000 in legal costs, but he remains over £6,000 out of pocket after spending £14,055 on legal fees.

A similar error affected Richard George, a fintech founder in Devon, whose account was debited £18,800 in late 2019. George’s original arrears had been written off in 2016, but CMS correspondence was sent to an old address, leaving him unaware of the pending claim. The agency eventually repaid the money and associated fees in 2023, yet the financial disruption persisted for four years.

A 2025 House of Lords report on the CMS found that about 23 % of reconsideration requests led to a changed decision, indicating a substantial error rate in the agency’s calculations and enforcement actions. The same report described enforcement as “random, abusive and unregulated,” noting that the system often punishes compliant parents while missing genuine avoidance.

What It Means These high‑value mistakes highlight systemic flaws in the CMS’s data handling and arrears verification. The agency’s inability to trace why Hammond was told he owed £19,000, despite a clear record of a settled case, suggests gaps in legacy data migration from the defunct Child Support Agency. The proportion of successful appeals underscores the need for a more transparent, auditable process before enforcement actions are taken.

Stakeholders are calling for an independent review of the CMS’s arrears database, stricter checks before issuing deduction orders, and a streamlined appeals pathway. As the Department for Work and Pensions faces mounting pressure, the next parliamentary session will likely examine whether legislative changes can curb wrongful deductions and restore confidence in the child support system.
