In a troubling revelation, numerous parents have reported significant financial errors by the Child Maintenance Service (CMS), with some losing tens of thousands of pounds they do not owe. Among them is John Hammond, a maths teacher from Peterborough, who discovered nearly £20,000 had been taken from his bank account, triggering a distressing battle to reclaim his funds. As the CMS faces mounting scrutiny over its practices, calls for reform are growing louder.

Shocking Discoveries for Parents

John Hammond, 56, was settling into his new role at a school when his routine banking check turned into a nightmare. Expecting to see his first month’s wages, he was instead met with the shocking news that the CMS had deducted £20,000 from his account. “I was so shocked that I couldn’t stop shaking,” he recalled. With his children now in their 20s, Hammond believed his child support obligations had ended long ago, and the sudden withdrawal felt like an elaborate scam.

His experience is not isolated. Over 30 parents have reached out to the BBC, sharing their own stories of miscalculated arrears and funds taken unjustly. Many of these cases date back years, even decades, raising serious questions about the CMS’s efficiency and oversight.

The Role of the Child Maintenance Service

The CMS was established in 2012, replacing the Child Support Agency (CSA), with the aim of ensuring that children receive financial support from non-residential parents. It employs a formula to determine payment amounts, and if parents cannot arrange payments themselves, the CMS has the authority to deduct funds directly from earnings, benefits, or bank accounts.

The Role of the Child Maintenance Service

However, instances of erroneous deductions have led to significant distress and frustration among parents. In Hammond’s case, he received a notification in 2019 stating he owed nearly £19,000, despite earlier correspondence from the CSA indicating that he did not owe anything. “It felt like banging your head against a wall,” he said of his futile attempts to resolve the issue.

Despite his persistence, the CMS proceeded with an interim order, deducting £19,269 from his account in December 2020. Although Hammond eventually won his appeal and recovered his funds, the battle took a toll on him financially and emotionally, leaving him over £6,000 out of pocket even after the court ruled in his favour.

A Pattern of Mistakes

Similarly, Richard George, a 63-year-old fintech entrepreneur from Devon, faced a shocking £18,800 deduction from his bank account. He had believed his child maintenance case was settled after a tribunal ruled in his favour in 2016, but unexpected CMS actions in late 2019 turned his life upside down. Miscommunication compounded the issue, as letters meant for George were sent to the wrong address, despite his efforts to correct the CMS records.

“It felt like a scammer had taken everything I had,” George said, recalling his panic upon discovering the missing funds. Although he ultimately received his money back, the ordeal left lasting effects on his health and well-being.

Calls for Reform

Concerns regarding the CMS have been echoed in a recent House of Lords report, which described the enforcement of maintenance payments as “random, abusive, and unregulated.” It highlighted a troubling trend where enforcement actions can occur before disputes are resolved, leaving parents vulnerable to unjust penalties.

Calls for Reform

The report also noted that the CMS’s calculation formula, which has been in place for over two decades, is outdated and fails to reflect modern family dynamics. With 720,000 paying parents relying on the CMS to manage 800,000 arrangements, the need for reform is becoming increasingly urgent.

The Department for Work and Pensions (DWP), which oversees the CMS, reported that nearly a quarter of decisions were altered after parents contested them. In 2025, the CMS received 92,700 reconsideration requests, with 21,400 resulting in changed decisions. However, the DWP has not provided data on appeals regarding arrears or bank deductions, raising further questions about accountability.

Why it Matters

The troubling experiences of parents like John Hammond and Richard George underscore a significant flaw within the Child Maintenance Service, one that not only affects the financial security of families but also impacts their mental health and overall well-being. As these cases highlight the urgent need for a transparent and fair system, the call for reform becomes not just a matter of policy but a necessary step towards restoring trust in a service designed to support children and their families. Without immediate action, many more parents may find themselves facing similar distressing situations.
