The Department’s system of child maintenance is not designed to protect those subject to domestic abuse or coercive control. The Department designed the current child maintenance system to emphasise collaboration between parents, with the CMS available as a voluntary safety net that separated parents can choose to use if they decide to. For survivors of domestic abuse, the CMS may be the safest and only way to secure maintenance from their ex-partner. Around three in five parents that apply to CMS report that they or their child had experienced domestic abuse. The Department points to the training and controls it has put in place to protect such parents subject to domestic abuse and coercive control. However, we are deeply concerned by submissions from stakeholders relating to how the CMS fails to provide these parents with appropriate support or consideration for their circumstances, and how the system exacerbates conflict between parents and financial coercion by requiring intervention from the receiving parent before CMS can take action in a case. This leaves the system open to being ‘played’ by parents wishing to exert coercive control over the other parent, including using the child maintenance system to continue to abuse their former partners, for example by withholding payments or access to children. The Department does not investigate why people stop using its services and whether there are any issues of financial or other coercion in such cases. It also knows little about separated parents without any form of arrangement, and therefore, whether some victims of domestic abuse of coercive control are prevented from using the service. Recommendation: The Department should, as part of its Treasury Minute response, outline how it will identify cases which potentially involve domestic abuse or coercive control and adapt its services and communications in response. It should build into its transformation plans: clearer routes for parents to flag and communicate do
