The UK's Child Maintenance Service (CMS) is under fire following reports of significant issues faced by both parents. Mothers are reporting arduous battles to secure financial support from ex-partners, essential for their children’s wellbeing. Simultaneously, fathers claim they are being incorrectly billed for thousands of pounds, creating substantial financial burdens. The BBC has been hearing directly from parents detailing their frustrating experiences with the system. These accounts highlight a perceived imbalance and lack of fairness in the CMS process. The problems suggest systemic flaws are causing considerable stress and financial strain for families already navigating the complexities of separation. These failings are prompting calls for urgent review and reform of the service.
