In a startling revelation, numerous parents across the UK, including John Hammond and Richard George, have reported distressing issues with the Child Maintenance Service (CMS) that have led to the wrongful deduction of thousands of pounds from their accounts. As these individuals seek accountability and clarity, it raises broader questions about the efficacy and transparency of the CMS’s operations.
Alarming Withdrawals Leave Parents in Shock
John Hammond, a maths teacher from Peterborough, experienced a life-altering moment when he checked his bank account during a lunch break at his new school. Instead of confirming the arrival of his salary, he found nearly £20,000 had been deducted by the CMS—an amount he did not owe. “I was so shocked that I couldn’t stop shaking,” recalled the 56-year-old, whose child support obligations had ended over a decade ago when his children reached adulthood.
Hammond is far from alone in this predicament. Over 30 parents have come forward to BBC Your Voice, detailing similar experiences with miscalculated child maintenance arrears and unapproved deductions from their accounts. Many of these cases involve arrangements that were finalised many years ago, highlighting a significant flaw in the CMS’s processes.
The Role of the Child Maintenance Service
Established in 2012 as a successor to the Child Support Agency (CSA), the CMS is tasked with ensuring that children receive the financial support they need when parents are not living together. The service employs a formula to determine how much a non-custodial parent should pay. If parents fail to arrange payments voluntarily, the CMS can withdraw funds directly from their wages, bank accounts, benefits, or pensions.
However, the recent experiences shared by parents indicate a troubling pattern. Many have reported that funds were taken “inappropriately” while they were actively trying to comply with their obligations. The Department for Work and Pensions (DWP), which oversees the CMS, has not directly addressed individual cases such as Hammond’s, stating only that enforcement measures are reserved for those who persistently fail to pay.
A Battle for Justice
Hammond believes that his ordeal began back in September 2002 when he received a letter from the CSA indicating he owed £947, which was not pursued at his ex-wife’s request. Fast forward to 2019, when the CMS erroneously claimed he owed nearly £19,000. After disputing the demand and presenting evidence, he found himself battling the CMS as they continued to enforce deductions.
Despite winning his appeal in 2021, which resulted in a court order for the return of the funds along with £8,000 in legal costs, Hammond remains over £6,000 out of pocket due to legal expenses. “Even when you’re proved right, it doesn’t feel like justice,” he lamented.
Richard George, a 63-year-old fintech director from Devon, faced a similarly distressing situation when £18,800 vanished from his account. He believed his previous disputes with the CSA were resolved, only to discover in 2019 that the CMS had mistakenly pursued him for arrears that should never have existed. After years of turmoil, the CMS finally acknowledged its errors in 2023, but George insists that the emotional and financial toll was already immense.
Calls for Reform
The troubling experiences of Hammond, George, and many others have prompted serious concerns about the CMS, which were highlighted in a recent House of Lords report titled “Reforming the Child Maintenance Service.” The report criticises the enforcement practices as “random, abusive and unregulated,” arguing that they disproportionately punish compliant parents while neglecting actual cases of avoidance.
There are also significant criticisms of the CMS’s calculation formula, which has remained unchanged for over twenty years. Many parents believe it is outdated and does not reflect the complexities of modern family structures. In response, the government has promised to review the CMS’s calculation model and is considering recommendations from the House of Lords report.
Statistics provided by the DWP reveal that the CMS currently manages approximately 800,000 arrangements for around 720,000 paying parents. In 2025 alone, the CMS received nearly 93,000 requests for reconsideration, with nearly a quarter of those decisions being overturned.
Why it Matters
The ongoing struggles of parents dealing with the CMS underscore a critical need for reform in the child maintenance system. As families navigate the complexities of financial support, the experiences shared by individuals like Hammond and George highlight the potential for systemic errors to cause devastating impacts on their lives. With a significant portion of decisions being overturned, it is imperative that the CMS addresses these issues swiftly and transparently to restore trust and ensure that child maintenance serves its intended purpose: supporting children’s needs without placing undue burden on their parents.
