In a distressing turn of events, numerous parents across the UK are grappling with significant financial losses due to errors made by the Child Maintenance Service (CMS). Reports have emerged detailing cases of incorrect deductions, with one father losing nearly £20,000 he did not owe. These alarming incidents have sparked calls for urgent reform in the child support system, highlighting the need for greater accountability and accuracy.
A Severe Miscalculation
John Hammond, a 56-year-old maths teacher from Peterborough, experienced a shocking ordeal when he discovered that the CMS had withdrawn £19,269 from his bank account. This unexpected deduction came while he was settling into a new job at a school, checking his finances during a lunch break. “I was so shocked that I couldn’t stop shaking,” Hammond recalled. His children, now aged 25 and 28, had concluded their child support arrangements more than a decade ago, leaving Hammond convinced that the withdrawal was a scam.
This situation is not isolated. Over 30 parents have shared similar experiences with BBC Your Voice, recounting instances of miscalculated arrears, unwarranted deductions from their wages or bank accounts, and prolonged legal battles with the CMS. These problems often stem from child support agreements established many years earlier.
The Role of the CMS
Established in 2012 to replace the Child Support Agency (CSA), the CMS is tasked with ensuring that children’s living costs are met when a parent does not live with them. The agency uses a specific formula to determine payment amounts. When private arrangements fail, the CMS has the authority to deduct money directly from wages, bank accounts, benefits, or pensions, and can also recover arrears if payments are missed.
Concerns regarding the CMS’s practices were raised in a recent House of Lords report, which indicated that many parents had money taken “inappropriately” while attempting to comply with their obligations. However, the Department for Work and Pensions (DWP), responsible for the CMS, did not address personal cases like Hammond’s or explain the reasons behind erroneous deductions.
Painful Legal Battles
Hammond’s troubles began in September 2002 when he received a letter from the CSA indicating he owed £947, a debt that was not pursued at his ex-wife’s request. Fast forward to 2019, and he was shocked to receive a demand from the CMS for nearly £19,000. Despite providing documentation to dispute the claim, he found himself frustrated by the system, describing interactions with the CMS as “banging your head against a wall.”
After enduring a lengthy appeals process, a county court judge ruled in Hammond’s favour in 2021, ordering the CMS to return the money and awarding him £8,000 in legal costs. Nevertheless, he spent over £14,000 on legal fees and still felt financially burdened.
Similarly, Richard George, a 63-year-old from Devon, faced a nightmare when £18,800 was deducted from his account by the CMS. He had believed a previous CSA ruling had absolved him of any arrears, only to be blindsided by the CMS in late 2019. After years of miscommunication, including the CMS sending correspondence to the wrong address, George finally had his funds returned in 2023, but not without significant personal and financial strain.
Calls for Reform
The House of Lords report titled “Reforming the Child Maintenance Service” raised serious concerns about the enforcement practices of the CMS, labelling them “random, abusive, and unregulated.” Parents have expressed that the system punishes responsible individuals while ignoring those who deliberately evade their obligations.
The CMS manages around 800,000 arrangements for nearly 720,000 paying parents. Yet, a staggering 92,700 requests for reconsideration were filed in 2025, leading to nearly a quarter of decisions being overturned. Parents often do not contest their obligation to pay child maintenance; rather, they challenge the accuracy of the calculations and the enforcement measures imposed before appeals are resolved.
Abigail Wood, chief executive of Gingerbread, a charity supporting single-parent families, emphasised the need for reform, stating that the CMS is “failing parents and children alike.” Michelle Counley from the National Association for Child Support Action called for enhanced collaboration between parents to resolve disputes more efficiently, avoiding the need for enforcement altogether.
Why it Matters
The ongoing challenges faced by parents like Hammond and George underscore the critical need for reform within the Child Maintenance Service. These stories reveal a system that, while intended to support children, is failing to protect the interests of parents and, by extension, the children themselves. As financial burdens and emotional distress mount, it is imperative that the government takes swift action to address these errors and establish a more just and transparent child support framework. Without significant changes, countless families will continue to suffer the consequences of a flawed system.
